Title: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: freddie on June 01, 2013, 07:28:39 am
CURSOR FREEZE PROBLEM

I've been running PP3 on my AA1 for a while now and have all the updates loaded.
I have Firefox 21.0
and Thunderbird 17.0.6
But running them together I have recently found that my session usually ends with the cursor freezing - usually in Firefox but it can be Thunderbird. I don't recall this happening before I started doing the regular updates.

F7 doesn't clear it,

I am a bit of a fast and furious typist, so I wondered if it is something like the speaker - where F8 turns it off, but to turn it on you need to click on the volume icon and unmute the speaker.

I wondered if you had any ideas?

When it next freezes .. can you hit Ctrl+Alt+T to open a terminal and run:
Code: [Select]
free -m
and post the output (I only really need the line that starts with Swap:)

Can you try using Chromium+Thunderbird instead of firefox and see if it still does it.

Is this AA1 with SSD?
Is the disk activity LED solid green?
If so then you are suffering from disk write lag.
Try moving Firefox cache into memory:

Firefox:
go to: about:config
filter: cache.
Set:
browser.cache.disk.enable false
browser.cache.memory.enable true
Check status:
about:cache

See if that makes any difference.

Thanks Mark and SeZo. Will wait and see at the next freeze.
SeZo - Yes - SSD - have now updated my profile

Post by: freddie on June 02, 2013, 09:13:53 pm
Froze in Thunderbird (no tabs), with Mozilla the only other active program (and 2 tabs open).
Disk light was solid for a few seconds after the freeze, then went out.
free -m gave swap 497 18 479
I did note the other readings if you want them

Does the mouse free up again when the green disk activity light goes out ?
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: freddie on June 02, 2013, 10:22:34 pm
No. The thing is so seized up that I was amazed I could rouse the Terminal.
Shutting down is a heck of a problem too
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: Mark Greaves (PCNetSpec) on June 02, 2013, 11:46:52 pm
OK, first of all if you can open a terminal you can shut down with:
Code: [Select]
sudo shutdown -P now

Secondly .. what happens if you unload the psmouse driver, then reload it:
Code: [Select]
sudo modprobe -r psmouse
then
Code: [Select]
sudo modprobe psmouse
does the mouse come back to life ?



BTW, I'm going to move these postings to their own topic after your next response .. though the issue IS related to Peppermint 3 and your AA1, it's not really related to the "installation" tutorial .. I'll also send you a link to the new topic by personal message (just in case you can't find it).

Agree. I think it should be separate topic, but I wasn't sure where to put it - I couldn't find a separate Peppermint section

Been trying to bring the fault up for half an hour by being busy, but I think that's the problem - just have to be patient and at some time in normal use it comes up - just when you least want it!

Post by: freddie on June 05, 2013, 05:22:30 am
I started with Thunderbird, and while it was active, this time the cursor froze in Firefox with two tabs open.
- BBC News
- Aljazeera - Turkish deputy PM apologises for 'excessive force'
(Oops! the cursor jumped in the middle of that line (and this) despite touchpad tap to click disabled)
http://www.aljazeera.com/news/europe/2013/06/20136411194960897.html (http://www.aljazeera.com/news/europe/2013/06/20136411194960897.html)

Disk light solid. Cursor frozen.
Unloaded mouse driver as you suggested; reloaded and all OK

Does that give any clues?

BTW that Aljazeera tab really hammers the disk light
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: Mark Greaves (PCNetSpec) on June 05, 2013, 11:11:15 am
Can you try something for me .. run this in a terminal:
Code: [Select]
syndaemon -i 1 -d
That will kill your touchpad whilst you're typing .. the touchpad will come back to life 1 second after you stop typing.

I just want to see if that makes any difference.

Be aware .. this will NOT survive a reboot, and will need entering again .. but if it improves things, we can make it load at bootup.

If (after running that) your mouse freezes .. try hitting any key, then waiting for 1 second .. does the touchpad start working again ?

Can you also confirm you made SeZo's suggested changes in Firefox, and what your "about:cache" page now says.

Hi
Sorry about the silence - been away...

1. CURSOR FREEZE IN FIREFOX
While away, when running Thunderbird, the AA1 cursor continued to freeze in Firefox (even with the cache mod) - with the disk light on solid.  Cursor reload worked OK.
Checking about:config it is still set to:
  browser.cache. disk.enable false
  browser.cache. memory.enable true

2. Cursor also repeatedly froze in Chromium - disk light on solid

3. KILL TOUCHPAD WHILE TYPNG
Thanks - that mod seems to work fine
How do I get to load at boot up?
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: Mark Greaves (PCNetSpec) on June 20, 2013, 11:00:15 am
OK, syndaemon autostart ..

Open a terminal and run:
Code: [Select]
mkdir ~/.config/autostart
then
Code: [Select]
gedit ~/.config/autostart/touchpad-pause.desktop

When a blank file opens in gedit .. make it read:-

Code: [Select]
[Desktop Entry]
Type=Application
Name=Touchpad Pause
Comment=Make touchpad pause for 1 seconds whilst typing
Icon=input-touchpad
Exec=bash -c "syndaemon -i 1 -d"
Terminal=false

SAVE the file .. and reboot (or log off/on) to test.



does the mouse become active again if you just wait for the SSD activity light to stop being on solid ? .. may take a minute.
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: freddie on June 20, 2013, 04:27:57 pm
Thanks

That all looked so easy, but when I tried to save it said:
Could not find the file /home/david/.config/auto…rt/touchpad-pause.desktop.
Please check that you typed the location correctly and try again.

Did a gremlin creep in somewhere?
The file seems to have that name, but even trying to save as with that name fails.
(Wish I wasn't still so virginal!)

Post by: Mark Greaves (PCNetSpec) on June 20, 2013, 04:38:39 pm
Sorry, my mistake, I forgot the ~/.config/autostart directory doesn't exist by default, so needs to be created first.

I've fixed the above posting .. so reload this page, then try it again.

Yeah
I worked that out, but by the time I had created the directories and saved it, you had replied!
(Maybe I should move up one grade from 'Linux virgin'!)

Anyway, it is running now, so I will let you know how I get on
BTW Terminal seemed to run at startup - is that how the patch works?
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: Mark Greaves (PCNetSpec) on June 20, 2013, 05:58:45 pm
I take it the terminal closed again .. it should.

I'f the terminal opening for a second is bugging you, let me know and we can try adding the command elsewhere.
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: freddie on June 20, 2013, 07:19:35 pm
Yes, terminal shuts down after a flash, but Oh dear, very quickly after startup the cursor froze again!

I had Thunderbird running and four tabs open in Firefox. The cursor froze in Firefox. Even when the disk light settled down and went out it still froze. The cursor keys scrolled the screen up and down but that was the only sign of life. (sorry - I didn't try to scroll the touchpad)

I unloaded the psmouse driver, but this time it seemed to do a quick reboot - all the programs shut down. I don't remember that last time. I then reloaded it and the mouse works ok.

Doesn't look like the cursor freeze and jumping cursor are related does it?
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: Mark Greaves (PCNetSpec) on June 20, 2013, 07:42:41 pm
Is this a new phenomena, or has the mouse always froze in Peppermint for you ?
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: freddie on June 20, 2013, 08:08:44 pm
No, my early experience of PP3 was good.

As I said in my first post, I seem to think it was only after doing the updates that freezing started to be a problem.
I have all the current updates. Is there any way of undoing them all?

The freeze above was with Firefox.

But last week, while on holiday I used Chromium almost exclusively and it froze every time :-(
- even when it was the only program running and only one tab open

Beyond a reinstall, then disabling updates .. not easily.

Possibly time to try Peppermint 4 ?

[EDIT]

Just a thought .. have we tried booting an earlier kernel ? .. if not, do you know how ?

Is it possible that you might be short of space?
Try running (to see how much space is used):
Code: [Select]
df -h
and to get more info on your HDD setup of the partitions
Code: [Select]
sudo fdisk -l
and the contents of fstab:
Code: [Select]

Shut down your AA1

Turn it back on, and as soon as you see the "Acer Empowering blah,blah" screen, hit and hold the "Shift" key.

You will eventually be presented with the GRUB boot menu .. you can let go of shift now .. use the "Down Arrow" key to select "Previous Linux Versions" (or similar), and hit the "Enter" key .. in the next menu, select the top entry (or any version that doesn't end with "recovery mode"), and hit the "Enter" key to boot that kernel.

Now see if the cursor freezes .. may be best to test it in chromium if that was the easiest app to get it to freeze in.

If there are no other kernels in that sub-menu .. let us know and we can try installing one.

Post by: SeZo on June 20, 2013, 10:22:19 pm
@ freddie
The output you posted indicates that there is no problem with disk space, so that is not the reason for the freeze. :-\
You could do some tweaking there to save wearing out your SSD, but that can wait.

Post by: freddie on June 21, 2013, 06:45:34 am

The only options are:

Peppermint, with Linux 3.2.0-23-generic
and
Peppermint, with Linux 3.2.0-23-generic (recovery mode)

Is there any difference?

I selected the first and couldn't bring up a cursor freeze with Thunderbird and Chromium
- but that doesn't mean much - this fault has a mind of its own!

Ran one complete pass of Memtest86 v4.20 with no errors reported, but noticed ECC disabled
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze
Post by: Mark Greaves (PCNetSpec) on June 21, 2013, 11:48:30 am
ECC will be disabled, you need a specific type of RAM for that, and a motherboard that supports it .. ECC RAM is usually found in servers.

Can you do me a favour .. open a terminal and run:
sudo apt-get update
then
sudo apt-get upgrade

does it mention anything about packages being "kept back" ?
Title: Re: PeppermintOS Three on an Acer Aspire ZG5 - Cursor Freeze

After the upgrade command it said:

The following packages have been kept back:
  linux-generic linux-headers-generic linux-image-generic

It also said the following, which is odd as the little shield icon says my system is up to date...

The following packages will be upgraded:
  dbus dbus-x11 libdbus-1-3 libgl1-mesa-dri libgl1-mesa-glx libglapi-mesa
  libglu1-mesa libpython2.7 libxatracker1 python python-minimal python2.7
  python2.7-minimal xserver-xorg-video-openchrome
14 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

   apt-get upgrade
       upgrade is used to install the newest versions of all packages
       currently installed on the system from the sources enumerated in
       /etc/apt/sources.list. Packages currently installed with new
       versions available are retrieved and upgraded; under no
       circumstances are currently installed packages removed, or packages
       not already installed retrieved and installed. New versions of
       currently installed packages that cannot be upgraded without
       changing the install status of another package will be left at
       their current version.
An update must be performed first so that
       apt-get knows that new versions of packages are available.

   apt-get dist-upgrade
       dist-upgrade in addition to performing the function of upgrade,
       also intelligently handles changing dependencies with new versions
       of packages; apt-get has a "smart" conflict resolution system, and
       it will attempt to upgrade the most important packages at the
       expense of less important ones if necessary. So, dist-upgrade
       command may remove some packages. The /etc/apt/sources.list file
       contains a list of locations from which to retrieve desired package
       files. See also apt_preferences(5) for a mechanism for overriding
       the general settings for individual packages.

For some reason the kernel updates weren't coming through .. dist-upgrade sorted whatever the problem was .. you're now running the latest kernel for Peppermint 3

If I remember correctly, the mint-update (shield by your clock) application is by default set to not retrieve kernel updates (which I think is stupid, and why I replace it with the Ubuntu one) .. so skip a few kernel updates, and you'll require a dist-upgrade to sort out other packages that were held back such as an xorg update and/or graphics driver update that requires the newer kernel.
(That why I don't consider Mints so called "smart" mint-update to be so "smart")

Is that what you were asking ?



With any luck that may have sorted the issue .. so just keep booting normally, and let us know if you're still getting the freezes.

I was doing really well...

Thunderbird + Chromium, four tabs open, tracking down this GCHQ stuff on the Guardian website.
The disk got busy occasionally and the cursor froze temporarily (and oops - it just jumped while I was typing that line)
Once or twice Chromium said a page was not responding, but shortly afterwards all seemed OK.
THEN the cursor froze solid. Disk light on full. I think it went out, but the cursor froze solid.

Then two funnies...
1. I hit Esc and Chromium bombed out but the cursor still froze.
2. That put me back into Thunderbird, but the cursor still frozen, so I hit cursor down and Thunderbird bombed out. The cursor became moveable again and I was invited to log in and all was back to 'normal'

Afraid I am out all day tomorrow, so won't be able to respond

Could you post the output from below (with Thunderbird + Chromium loaded with few tabs):
Code: [Select]
free -m
It might be trying to use swap but stalling in the process.
Also does this happen when on battery or mains (or both)?

You could try to get the write speed for your SSD (might haveto install hdparm)
Code: [Select]
sudo hdparm -Tt /dev/sda
This would show the settings for how agressive the use of the swap
Code: [Select]
cat /proc/sys/vm/swappiness

No problem. ;)
For tomorrow, you could try (after boot up) setting the swappiness to 10 temporary.
(it will start swapping out around 80-90% of memory.
Code: [Select]
sudo sysctl vm.swappiness=10
and see if that delays the freeze up.

The SSD read speed is quite low at 32.13 MB/sec. the write would be even lower.

It's odd because nobody else has reported a freezing cursor .. yeh, the annoying I/O pauses caused by the very slow SSD .. but no cursor freezes, even with only 500mb RAM.

That's why I suggested moving to PM4 or reinstalling PM3 .. I'd say check the SMART data for the drive, but the AA1 smart data doesn't support SMART.

I'll be typing up a Peppermint 4 tutorial as soon as Peppermint 4 is added to Pendrivelinux's Universal USB Installer so you can have persistence .. yes I know I could use Unetbootin or similar, but I want the tutorial to be able to create a "persistent" LiveUSB from a Windows PC, you can already create one from within Ubuntu/Mint/Peppermint/Debian/etc. but I figure most people will want to create it in Windows.

Meanwhile if you want to give PM4 a shot .. I'll be happy to talk you through creating a PM4 LiveUSB in PM3.

Found a way to unfreeze the cursor...

Ctl-Alt-Del
'Switch user'
and log in as self again (both for OS and screen saver)

- quicker than rebooting, and ALL the programs remain as they are!

That would suggest it's an xserver issue (probably xserver-xorg-input-evdev) .. what's the output from:
Code: [Select]
dpkg -l | grep input

Let's try:
Code: [Select]
sudo apt-get install --reinstall xserver-xorg-input-evdev xserver-xorg-input-mouse xserver-xorg-input-synaptics
once that's finished .. reboot.

Next up .. if that makes no difference .. going through your log files for clues.

Wow!
What was all that? - quite a screenful of mods.
Did I get a bad mix of drivers previously?
Anyway - done. Will let you know either way after a few days (hopefully nbot before!)
Thanks again for all your help
Cheers

We've pretty much reinstalled all the input stuff .. dunno if it will make a difference, but I figure "Hey, worth a shot" :)

Fingers crossed.

Spoke too soon!
My manic typing has brought up the cursor jump problem again.
- going all over the place!
Do I need to put that patch in again?

I wouldn't have thought so .. does the touchpad stop working for 1 second during typing ?

Hi Mark

Sorry about the silence, but not been able to get online until today.
- the wires fell out of BT's junction box up the pole near our house (Yes!)
- only rewired six months ago!

Very hard to tell if touchpad stops working. I guess I am just going to have to slow down in my old age

But no more cursor freezes since that last big patch, so here's hoping!

Thanks again for all your help

Still no cursor freeze since reloading as per your instructions despite running Thunderbird, Firefox and transcribing madly into gedit (Yippee!)

HOWEVER my understanding of cursor leaping has progressed

1. With 1 sec touchpad delay the cursor leapt about all over the place even when typing slowly. Also the contents of my last copy were pasted, and sometimes great chunks of text were deleted.

2. Going to a 3 sec delay there were no errors despite manic typing and transcribing 5 mins of speech. However the 3 secs made moving the cusrsor a tad cumbersome

3. Going to a 2 sec delay seemed to work OK, but then all of a sudden the Thunderbird and gedit icons disappeared from the bottom line of the screen. Opening gedit and the file I was editing I got the message that the file was already open in another gedit window - but I couldn't locate it or access it! Thunderbird I could not open. Task Manager showed gedit and Thunderbird present but not running. I couldn't find out how to get them running, but I did kill them and restart, but lost the gedit text I had enetered since the last save :-(

Does the above offer any clues?

Yeh, you'd switched desktop  .. the apps were still open on the other desktop.

Hit  - Ctrl+Alt+Arrow

Where Arrow is the left or right arrow key, to switch desktop.

Isn't there also a desktop switcher on the bottom panel of Peppermint 3 ? .. can't remember, I'm now on Peppermint 4

I hope you don't take this the wrong way, but - Thanks freddie, that made me spit out my coffee  ;D

Clever stuff. I will know next time.
No, there deosn't seem to be an option with Peppermint3
But why all the messing around when I have 1 and 2 sec delays?
I am back to 3 secs

Post by: Mark Greaves (PCNetSpec) on July 01, 2013, 09:42:03 pm
I have no idea, it makes no sense to me .. the touchpad should be OFF when typing .. the amount of delay shouldn't make a difference.

Have you tried running running:
Code: [Select]
sudo modprobe -r psmouse
then
Code: [Select]
sudo modprobe psmouse proto-imps
and seeing if that makes a difference ?

also try:
Code: [Select]
sudo modprobe -r psmouse
then
Code: [Select]
sudo modprobe psmouse proto-exps

Neither of these will survive a reboot, but if either helps we can make it permanent.

Thanks Mark, but while you were preparing those instructions I had cursor freeze after freeze after freeze...

Running Thunderbird and Firefox, with 4-5 tabs on and opening sites - looking at my BT account, abebooks, amazon BBC News and other sites etc.

Firefox settings are still:
 browser.cache. disk.enable false
 browser.cache. memory.enable true

And to cap it all, restarting after the last freeze, Thunderbird brought in ALL my emails from the server again, but Remove Duplicates sorted that out.

I give up. Is my machine jinxed?

Can I upgrade to Peppermint 4 without losing all my emails and files?
And if so, have you done a tutorial on it? (among the millions of other things you manage to fit into your busy support life!)

Erm, not really .. there is NO (safe) direct "upgrade" path in Peppermint .. the only safe way would be to reinstall .. that said It shouldn't be too difficult to copy off your  thunderbird directory and other files to another drive (USB stick or USB HDD), then copy them back after reinstallling.

And if so, have you done a tutorial on it?

I haven't done a Peppermint 4 tutorial for the AA1 yet, simply because I'm waiting for someone like PendriveLinux to release a LiveUSB creation tool that supports "persistence" on Peppermint 4 .. there are ways around this, such as simply renaming the ISO to Peppermint 3, and in any case persistence isn't required for installation .. so if you wanna give it a shot, I'm willing to help you through it ?

Does your touchpad/cursor fly around if you run Peppermint from a LiveUSB ?

Oops! Didn't get a notification of that post.

Sorry, can't answer that Q at the moment

I Googled: linux cursor freeze
and I see I am not alone.

At the last freeze I pressed Ctrl and it immediately rebooted. I am beginning to wonder if both the cursor freeze and jump could be a keyboard problem?

They certainly *could* be a hardware issue .. mine doesn't do it .. but that doesn't mean much on its own.

It would be interesting to know if it still jumps around when booted to a LiveUSB.

If it originally didn't do it with Peppermint 3, and you boot to a LiveUSB, if it DOES jump around it would tend to indicate hardware, if it doesn't, it would tende towards software.
