Linux Support / Ubuntu - Constant disc access - SOLVED
« on: July 09, 2012, 01:04:49 pm »
The disc-access light seems to be on continuously despite disconnecting the network and not running any s/w.  If I run System Monitor, it shows all processes to be sleeping (except for SysMon of course). 
I can understand some background, automatic  defragmenting (does Ubuntu do that?) but that must finish eventually. 
It's not a big problem (I hope) but I'm curious.  Any ideas?

Linux Support / Removing files & directories
« on: June 23, 2012, 04:23:18 pm »
I want to remove all the files and subdirectories of a temporary directory   var/lib/apt/lists.backup    but don't want to delete every file individually as there are too many! 
I am not familiar with “recursive” when used in the context of directories but, after browsing the manual, am hoping that the command
   rm -v -r  var/lib/apt/lists.backup   
will do the trick. 
Your advice would be appreciated before I screw up everything. 

Linux Support / Ubuntu update error
« on: June 23, 2012, 01:43:31 pm »
I am running Ubuntu 11.10 successfully, until yesterday when the automatic invocation of the Update Manager showed an error. 
The update appears to be related to Mozilla products (mainly Firefox?) and upon clicking the “Install Updates” button, I received the error message:
   “Requires installation of untrusted packages.
   The action would require the installation of packages from unauthenticated sources.”
I attach a Print-Screen *.png file for the full info. 
Clicking on “Close” showed that the Update Manager had stopped the process.
Just in case there had been an error in the transmission of data I launched Update Manager manually but the the same thing happened. 
I considered updating files one-by-one to catch the culprit, but since all the files appear to be related, I haven't done so.

Has anyone encountered the same problem?  And more to the point: is there a solution? 

Linux Support / Missing Application - Solved
« on: March 20, 2012, 02:38:35 pm »
I wanted to copy some files from a USB stick to a CD.  I expected Brasero to start but a default application with no name persuaded me that it was doing as requested.  Sadly, the CD was empty so I went in search of Brasero.
I am using V11.10 in classic mode, and Brasero used to be in Applications/Other or Applications/Accessories but was nowhere to be found.  Thinking that perhaps I had removed it from the display list, I viewed the entire available set of menu items using
Applications/Other/Main-menu, but it was not listed.
Had I deleted it?  Ubuntu Software Centre told me it was installed.  So I un-installed it then re-installed it.  And it is still not listed in the Applications menus. 

Hmm!  Any ideas anyone?  Is there a sudo command to list installed applications?

Linux Support / HP Photosmart 7280 wireless connection - Solved
« on: February 27, 2012, 11:29:52 am »
You are kindly helping me with my friend's Epson wireless printer.  This is a similar post for my HP Photosmart 7280 so as not to confuse.
There are  /etc/sane.d/ files for several HP printers , but not the Photosmart 7280, and the SANE website indicates that the USB Photosmarts are not supported by SANE.
On HP indicates full support for the 7280 in Ubuntu V11.10, though without indicating the network parameters, but does offer a download that I haven't dared try.  Your advice would be appreciated. 

Linux Support / A laptop suitable for Ubuntu? AsusK53S
« on: February 22, 2012, 06:26:45 pm »
I have been asked to purchase a laptop for an elderly, ex-academic who wants a machine that will be reasonably future-proof (say 6 years).  My local PC repairer recommends Toshiba for their internal ruggedness and I have found one (C670) at my local Argos store:
Just to be on the safe side I would be grateful if someone would mention any known problems running Ubuntu 11.10 on this series of laptops. 
I bought an Ubuntu V11.10 disc from the Canonical Store which they advertise as “for desktops”.  Would it be OK for this laptop?  It certainly won't load onto my old Dell D505 – but that's another problem being addressed elsewhere on this forum. 

Many thanks.

Linux Support / Upgrading from 11.04 to 11.10 on Dell D505 - Solved
« on: February 20, 2012, 11:39:13 am »
My Dell D505 has V11.04 installed.
I tried to install V11.10 from a disk but it turns out that the display/driver is not adequate.  I tried the Dell website and forums for suitable upgrades but found no joy.   
Unfortunately;  now that a few files have been transferred from the V11.10 disk to the laptop it keeps downloading files for V11.10 but can't install them, of course. 
How can I stop this?  Apart form buying a modern laptop! 

I gave my keyboard away to a friend yesterday with a V11.10-loaded PC (spreading the word) knowing that I had a brand new, spare k/b at home.  But Ubuntu didn't recognise it - just booted itself into Ubuntu awaiting a password. 
The new mouse was OK so I tried to use the on-screen keyboard.  I was too ham-fisted and gave up after a few tries, opting (wrongly as it turned out) to just try another re-boot.  Bad mistake!  Now my PC just hangs at the dual-boot screen.   
I can't find anything by searching this Forum that might help.  Is there anything that can be done using the installation disc? 

Fortunately I have an Ubuntu 10.4(?) laptop to tell you about it, and would be very grateful for advice. 

Linux Support / Wireless printing in Ubuntu V11.10 - Solved
« on: February 18, 2012, 02:57:03 pm »
I added an HP 7200 series printer without any problem just by plugging it in.  I have now given the PC to a friend who has an Epson PX720WD printer.  When plugging the USB cable into the PC, Ubuntu doesn't respond.  I tried System Settings/Printers but the add-printer “+”  button was greyed out. 
Any ideas?

Linux Support / No sound output from Ubuntu desktop - Solved!
« on: January 29, 2012, 06:31:21 pm »
My own PC with V11.10 works very well and I offered to upgrade a free desktop that came my way for a friend.  Ubuntu V11.10 loaded without problems and I even managed (with some help from this Forum) to get the wireless network going.  And the HP printer works as well! 

Sadly, though, there is no sound output.  I have searched several forums and other sites for advice, but most of it is for rather old Linux distros. 

I have used all the system checks that I can find, and used several terminal commands found on the web to examine audio drivers and hardware, but it's beginning to look as though the amplifier is not working.  I attach a file of my efforts and the results and would be glad if someone would advise me. 


Linux Support / Creating a wireless network in Ubuntu V11.10 - Solved
« on: January 04, 2012, 07:02:09 pm »
I am running Ubuntu V11.10 and, after a few glitches sorted out with help from this forum, I am very happy with it since discovering that I can run it in Classic View. 
My next task is to set up a wireless network.  My only experience of trying this in XP was disastrous so I am starting by asking for advice, having searched the Forum on the subject.   
My goal is to have my desktop wired to a router/modem (one device or a pair) and have a laptop (also Ubuntu) and printer connected wirelessly. 
Whilst Ubuntu is great at interacting with whatever device I plug into it, I want to be sure that I buy the “best” wireless adapter and router/modem combination for my purpose without getting out of my depth.  I found a web-page somewhere that recommended the  Thomson SpeedTouch 546 or Belkin N1 for Linux. 
So:  which device(s) would Forum users recommend (and why) and what advice would they offer a wireless novice in setting up such a system?
My PC is ?? without a wireless adapter. The laptop is a Dell Latitude D505 and the printer is an HP 7200 series, to be replaced with an Epson PX720WD when I give the system away to a friend.  I note Topic post 9844.0 on the subject of wireless printers. 
Oh, and a Happy New Year to all my readers. 

Linux Support / Ubuntu V11.10 problems
« on: November 12, 2011, 06:44:02 pm »
I started Linux with Ubuntu V 11.04 and liked it very much.  When the Update Manager offered V11.10 I accepted despite many problems with the installation due, probably, to a poor broadband connection. 
I found V11.10 rather slow to respond - e.g. ALT+TAB took about 1sec to tab between applications and I could easily out-type LibreOffice writer. 
Now LibreOffice has become ultra slow and the spreadsheet locked me out while it auto-saved repeatedly.  Manual saving was refused.  FireFox is now at a snail-pace (except for this typing) and I have to wait many seconds for the scroll to catch up. 
I am at my wits' end and long for V11.04  -  can I go back?  Any solutions?
(As a general comment: I preferred the Classic View of V11.04.  This V11.10 is beginning to feel like a move to Microsoft bloatedness.)

Linux Support / Running Ubuntu from CD on Vista laptop
« on: September 20, 2011, 02:15:37 pm »
My mate wants to try Ubuntu on his Vista laptop but I can't change the boot device order - looks like Vista thing. 
I found a website ( that provides a method of running Linux from CD without rebooting but it requires a file (StartLinuxCD.exe) that I can't find on the web. 
Any ideas anyone?

Update 22/11/11:
I revisited this problem armed with an Ubuntu 11.10 disc purchased from Canonical.  Pressing F12 during POST did indeed produce a boot choice list and choosing CD worked perfectly.

Internet Connectivity / Thunderbird
« on: September 12, 2011, 01:37:59 pm »
Dear Forum,
Having had wonderful help from the Forum when installing Ubuntu, I would be grateful for help with a long-standing problem with Thunderbird. 
When using it on XP it was fine until I upgraded it and suddenly I could send but not receive Emails.  Now using Ubuntu, I have tried but can't get on with Evolution so installed Thunderbird in the hope that it would be compatible with Ubuntu.
Sadly not - the same error message occurs:   Sending of password did not succeed. Mail server responded: Incorrect username or password.
I have checked all the settings, of course, to no avail. 
This is beginning to look like a BT/Yahoo problem, but I would be grateful for advice from anyone with similar experience. 
Many thanks.

Linux Support / Lubuntu installation
« on: August 07, 2011, 01:08:21 pm »
Dear Forum,
I have read here several plaintiff cries from new Linux users and am heartend by the assistance being offered.  And yes, you've guessed already: I am a new user with a problem.
Some backgound:  I have been writing scientific s/w for some years before retirement and am reasonably familiar with XP Home (even modifying the registry!) but have no knowledge of the mechanics of operating systems, and Linux does seem to need some expertise.
I acquired a distro disc with a Linux magazine and attempted to install Lubuntu 11.04.  It ran fine directly from the disc but the installation failed miserably. 
The first error message: ........comp.bus not detected.  Module not inserted.
Then lots more unintelligible ones, but the installation continued until it crashed near the end.  Each installation attempt provides some different error messages including a suggestion that my DVD or HD drives are faulty.  Not true as I can run Lubuntu from the DVD and can re-install XP SP1.  None of the other distros on the disc (Xubuntu 11.04, TinyCore Linux 3.6) will install either. 
I would be grateful for advice:  should I purchase a Ubuntu disc from a reputable supplier (e.g. CodeSages), try another distro type, or do I have a problem with my system that prevents Linux installation?
My PC is very old: AMD Athlon 1.1GHz with 1G RAM and new 160GB IDE H/D. 
Your assistance would be appreciated.
