Ubuntu / Re: Ubuntu getting slow
« on: Yesterday at 11:35:39 pm »
Hello Mark,

I've been trying this, but there's no obvious culprit. FF and Chrome (which I'm reluctantly trying because FF keeps giving me the "Well, this is embarrassing" screen) tend to use a lot of CPU, especially when streaming videos, but I haven't seen the whole machine freeze up again.

Obviously I can't open the two terminals until the machine is running, so they don't offer any clues as to why the boot process takes so long (consistently around 100 - 120 seconds to a usable desktop). FF also starts up amazingly slowly.

I'm beginning to think in terms of a full reinstall of Ubuntu 16.04...

IO is in the order of 0 - 4%, with occasionally 7 - 9%.

sudo smartctl -A /dev/sda gives..

No, I don't think so. I also use Chrome and/or Chromium.

Slowness seems to be the order of the day. Swap is being used, albeit minimally. Do you think this may be a physical memory problem?

This is getting silly now. I've just spent over five minutes listening to constant disk accessing and waiting for this PC to become responsive again. I couldn't shut anything down, open a terminal, or anything else.

I was on the point of a hard reboot when things finally started responding. The terminal showed this;

By the clock on my desk.

I just tested it again. From clicking 'restart' in Ubuntu, it was 90 seconds until the desktop appeared, with lots of disk accessing still going on. I clicked immediately on the Firefox icon and it took another 40 seconds for FF to load and be useable.

Sorted. Outlook.com has imported all my emails and folders without fuss.

Anyone trying this should be aware that you need to use imap, not pop.

Ubuntu / Ubuntu getting slow
« on: May 20, 2017, 10:52:08 pm »
My main Ubuntu machine (Ubuntu 16.04, core2 duo + 4GB Ram) is taking almost 2 minutes from pushing the button to a functioning desktop.

I'm sure it used to be a lot quicker and I haven't made any changes lately.

Does Ubuntu gradually slow down like Windows?

Has anyone got any recommendations for another, preferably free, account provider?

We have two fsmail.net accounts going back years, hence a lot of messages/folders to transfer. Transferring them to gmail seems to be fairly straightforward, but I simply don't want to be involved with google and it's quest to know everything about everybody on the planet. I don't even use it's search engine.

So what I need is a new, non-google account into which I can import messages from fsmail, but I can't seem to find one. Yahoo would be ok, except it imports from only a limited number of other providers, excluding fsmail.

It doesn't have to be free. I'm wondering about buying a domain name and using it's email facilities without creating a website. Trouble is, I'd still have the problem of importing a multitude of old messages, contacts etc.

Everything seems to be working ok now. I created a new VM and the owner was 'me'.

The old VM works as does a clone I made of it.

I didn't copy from another machine, and the only way I can think I was running with elevated privileges would be if I'd elevated them to do updates immediately before creating the old VM. Is that even plausible?

Thanks Mark. I'll make this solved now..

PS: the weird thing is still that when I use the 'search your computer' feature it finds only the old version. Although it says it's installed 'nowhere', I still have the uninstall option available..

Thanks Mark,

The change of ownership seems to have worked. The VM now appears in the Virtualbox list of VMs and I can start it.

Next step is to create another VM and see who the owner is..  I'll try that in the next couple of days. I'll wait till then to mark this thread solved, although I think it is.

Thanks again.

PS: I'm now starting to read resources about the command line. Bit like learning DOS all over again.. Happy days. Then along came Windows 3.1...

I've just uninstalled vn 5.0.36 of Virtualbox, and installed vn 5.1.18. At least I think I have.. However, when I use the 'search your computer' feature in Ubuntu 16.04, it still seems to find the old version, although it says it's installed 'nowhere'.

Confused? Me too, but it gets better, or rather, worse.

Immediately after installing the new version I was able to add a VM from the previous version, start it, use it and suspend it while I went out to the Co-Op (I live life in the fast lane..)

Now I open Virtualbox to find the welcome screen and no existing VMs. What's more, I can't add the same VM again. I get the following message...




Runtime error opening '/home/mike/VirtualBox VMs/XP/XP.vbox' for reading: -38(Access denied.).
/home/vbox/vbox-5.1.18/src/VBox/Main/src-server/MachineImpl.cpp[485] (nsresult Machine::initFromSettings(VirtualBox*, const com::Utf8Str&, const com::Guid*)).

Callee:
IVirtualBox {0169423f-46b4-cde9-91af-1e9d5b6cd945}



I've tried moving the VM to my home folder in case that helped, but Ubuntu tells me I don't own it, so I can't move it.

I'm the only user of this PC and I created the old VM, so how can I not be the owner?

As always, thanks in advance for any/all help..

Internet Connectivity / Re: loss of wi-fi connection

Bingo! Rebooting the router worked.

Don't know why I hadn't tried it in the first place. Probably because the iPod connected easily and the wired connections were fine. And because I'm no comms expert and I was bogged down at the laptop end, tweaking settings and looking for something more complicated.

Thanks Mark..
