Ubuntu :: Strange Bug Renders Keyboard Unusable?
Apr 11, 2010
I have encountered the strangest bug, filled with so many inconsistencies that I am unable to comprehend why or how it is happening. It has only happened once and whilst it seems to resemble another bug that I found when looking for this one, it is fundamentally different. Here are the facts:1. I am using an Acer Aspire One netbook.2. This netbook is running Ubuntu 9.10.3. It has been running Ubuntu 9.10 since the first time it was released as stable.4. Yesterday, whilst I was engaging in an intellectually stimulating debate through the convenience of Pidgin, I encountered the said bug with the following attributes:The keyboard has the appearance of not working.
But if one applies a lot of pressure to each key, one is able to type.This bug is not resolved by a system reset.This bug does not affect my BIOS or even Ubuntu until I log into the particular account where it first happened.When I log out of the account and log into another one, my keyboard is perfectly responsive.When I log back into the "damaged account", the keyboard is once more unusable.The right click menus do work, in stark contrast to another, similar bug, the report of which I encountered in my search for this one.So, clearly, an undesirable workaround would be to migrate to a new user on my system. This, however, does not change the fact that I do not wish to do this another time if the bug repeats itself. Furthermore, if it is only active in a session of the "damaged account", it is likely that it is a configuration error of sorts, no? I have another strange configuration error on that account. The little icon that allows me to choose to which wireless network I wish to connect is random in when it chooses to appear or not, although the service is active (as I am greeted with a message directing me to click on the non-existing icon in order to select the network...). Yet again, this only happens when logged into a particular user, while other users seem completely unaffected.
What I conclude from this is that Ubuntu's configuration system is pretty erratic and it makes seemingly random yet seemingly irreversible changes to user configuration. I would not even know where to start when faced with reading through different configuration files. Furthermore, I would feel as though my PC were constantly working against me. It is a strange feeling, when I bought it with the intention that we might work together.

After doing the standard sequence to go from 10.4 to 10.10 beta, the system is now unusable.There are no icons and no thees. The GDM login shows a big question mark where a graphics would normally be.When I log into the session, I get nothing: no desktop, no panels. Alt+F2 does nothing, so I can't even launch a terminal that way.After starting a terminal from a virtual console, I can start looking at what's wrong. Metacity crashes right awaywith:metacity:ERROR:ui/ui.c:752:meta_ui_get_default_window_icon: assertion failed: (default_icon)Aborted (core dumped)

I formatted a 1.5 Tb western digital external usb drive to ext4 for media streaming on ubuntu-server. I tried FAT32/NTFS before but it keeps unmounting itself for no reason. I tried everything I could find on Google but no luck. After formatting it to ext4, it worked OK for a while but for some reason it has stopped working. Running mount -a makes system unusable indefinitely. It works only if I restart it.
UUID=db261dd6-2edf-4020-a0f5-17613a6e94ea /media/wd ext4 defaults 0 0
Is ext4 not a compatible format for external drive? Since, I have I tried different formats and Ubuntu keeps unmounting them. Should I try a different distro?

I have a problem after running zypper up. Apparantly somehow it upgraded to current factory release.. Problems so farNo networkNo x - session(after a quick hack i have x started but no input devices work)I think there is something wrong with udev and my xorg.confx first complained about InputDevice not being recognised.. I moved away my /etc/X11/xorg.conf and got a quick running session (without input devices, so icannot log on) but after a reboot it gives me a "black" screenWhile troubleshooting is encountered the problem that my network card is not recognised.. This all points in the direction of udev or whatever to be badly configured during upgrade..

I am currently running squeeze with the 2.6.32-trunk amd64 kernel.
If I close the laptop lid the screen will not turn back on and the laptop becomes unresponsive. The only way to get it functioning again is to hold the power button down until it dies.

I recently bought a second monitor and I had this set up perfectly fine with two panels on my primary display and one on my secondary. I've now gone away for the weekend (leaving the monitor) and I went to turn on my laptop and it didn't work.
When I login to a gnome session (or indeed a failsafe gnome session) I just got two horizontal white bars (where the panels would be). I switch to a terminal, login and run top and see that gnome-panel is on 100%. Running 'killall gnome-panel' does nothing (tried a few times).
I've had to install xfce4 just to type this message. Is there any way I can 'reset' gnome-panel or any other fix? Or even a workaround would be nice. I'm on 9.10 by the way. I am going to upgrade at some point but its not really an option yet.

My mom's computer is no longer bootable. I was thinking of attempting to fix it later on this week and am thinking of doing a chroot and updating via a live CD hoping that an even newer update solves the problem but I have some doubts of success. Does anyone have any information about this issue so that I can be better prepared to fix it? Also, I thought I should mention that I tried the second newest kernel to see if that would make it work. It didn't. The error is something along the lines of having the /dev/diskuuid change. If I'm correct, Ubuntu changed the disk's name and is trying to boot the old name. It's dropping to an initramfs shell (not the regular terminal where you can work miracles ).

I did a routine update of my ubuntu 10.4 (in wubi vista) to the latest kernel (something -26) and installed a java plugin for firefox. After a reboot, i open up the "Ubuntu" entry and i see a message flash accross the screen (something about hda,0,0 or sda im not sure) then it just reboots the PC. No command line or anything. No need to say im pretty screwed
My question is, is there any way to get my files off of wubi? Or even better can i restore Ubuntu to working again? P.S for some reason the two times i have tried to run a live CD on this laptop, it has corrupted vista.

I noticed (in my couple of days Debian experience) that most of my PDF files renders poorly in Evince. And poorly is gentle word to say, as they are unreadable: So I searched Software Center for some programs and installed XPDF, but this program does not belong in my time perception so I ditched it. Then googling, I found Foxit deb package, which shows fine: but I'd like to use something else if possible on Linux system I did not try to install Adobe Reader as I understand it's bloated and slow program, and I felt nostalgic towards SumatraPDF which I use on my Windows 7 OS. I guess there is no hope for such slick PDF viewer on Linux, as I googled as said, but knowing that SumatraPDF's PDF engine is MuPDF, I just feel sorry that developers prefer only Windows version I'm curious which program, experienced Debian users find appropriate for viewing PDF files

I am working on an application that will convert English text into equivalent Indian language text. Since Unicode is the standard, I will be using it. In most of the western languages each code-value directly refers to the glyph index and placing the code-values side by side will give the required display. This one to one mapping is not possible in Indian languages where rendering syllables is required rather than rendering just consonants and vowels. Many of the complex characters are made up by combining several unicode values.
My question here is: How Linux renders this Unicode text correctly? More specifically, what package is used? I believe in Windows they use Uniscribe for rendering.I believe there will be an operating system library for handling the text rendering. Or do I need to write my own rendering engine? How programs like Firefox, GEdit shows unicode text? Do they also have proprietary engines for correct rendering?

I have copied my Windows fonts to /usr/share/fonts/. While I understand that they can't exactly be rendered like they are on Windows, this Verdana rendering looks odd.(CSS style: font-family: verdana, arial, sans-serif;)Notice how that "N" in "Norton" and the "V" in "Virus" look obese? By means of comparison, here's the font viewer's rendering of Verdana:

I recently installed Debian 5 04 AMD64, when I double-click on any HTML document it is rendered in very large characters.I guess one of the browsers installed (Iceweasel or Epiphany) is selected by default but I cannot find any clue as to which one.What puzzles me most is that I have not yet edited the Apache2 config files to give access to the directories where these files are stored, nor the user etc, and as far as I understand these HTML documents should not yet be available to Apache2 and the browser.

So I'm trying to copy some media from my main hard drive to an external drive.In particular, I'm clicking folders (each containing O(15 GB) in files) and dragging them into a folder on my external HD. Fedora pops up an error message saying there was an I/O error for some of the files I'm trying to copy.So, now, some of the directories copied right, and one seems to have gone haywire. In particular if I navigate to /media/China Disk/TV/Battlestar/ and then run ll, I get the following output
Code:
ls: cannot access Battlestar.Galactica.S03: Input/output error
total 12

And we are unable to restore the setting because the button to click on to do so is outside of the viewable screen! Also we have lost the start bar/dock at the bottom of the screen and cannot figure out how to get it back.

Like my title states, Compiz or any desktop effects aren't usable for me in 10.04. Never had any problem with any previous release. I'm using the open drivers with my ATI 1950 GT. At first I thought it was due to the fact that I have dual monitors now, but after disabling one and trying again it still acts up.
All I can explain it is it's as if my desktop were "lagging". My mouse cursor will jump and stay in a certain area and I can only move windows a short distance before my mouse pops off and the window jumps back. Minimizing windows also seems like it's a burden on my computer and will take a few seconds to do so.
This is the same setup I've had over various distributions and this is the first time I've experienced it. Anyone have any idea if it's fixable or if my computer is just finally getting too old? I can post the rest of my specs if they're needed.

So if we don't like Unity or the way it crashes with alarming regularity, the fact that it requires multiple mouse clicks to do things we used to do with a couple and the fact that the launcher is not configurable in any meaningful way, we can always go back to Ubuntu Classic, right? Wrong!
Trying to enable desktop effects in Classic under amd64 and NVidia proves something of a nightmare.
1. There is no 'Desktop Effects' tab anymore. We are told that this is no longer necessary as Compiz is running by default.
2. Jockey reports that the NVidia driver is installed and that the driver is activated but 'not currently in use'. This is a bug and has been reported. However, this could tempt people to uninstall and re-install the driver (I am one of these) with disastrous results.
3. Trying to enable things like the Cube and Cube rotation break Compiz and remove *all* the settings in CCSM. Window menus and borders disappear and have to be restored by resetting the Window Manager to Metacity.
4. Getting applications like Radio Tray or Shutter to show in the System Tray involves circuitous circumventing of a 'Whitelist' (which is there for our protection because we shouldn't really want to use applications which put icons in the tray!) is really going to put off people installing applications which then apparently don't work. (They do work, they just become unusable because you cant see them or do anything with them!)
5. Skype will sometimes load and sometimes won't. Sometimes the sound is corrupted and sometimes not. Despite the fact that Skype is proprietary software, many people need to use it. If it becomes unreliable many people will look elsewhere or go back to Wingedows.
6. In both Unity and Classic the task bar will randomly freeze and become unresponsive, requiring a reboot.
Natty Narwhal? More like Natty Dread at the moment. I dread turning it on and it is dreadful. I'll try Gnome 3 or go back to 10.10. I can no longer recommend Ubuntu as a viable alternative to Windows to my customers.

I've been using Ubuntu 10.4 for nearly a month now and am very happy with it, especially the ability to add and upgrade programmes which up till now was a nightmare with worries about dependencies etc. I do have one major gripe, and that is Firefox 3.6.3. I gather others have had the same problem. At start-up Firefox works fine, but after about 12 hours, it becomes so sluggish as to be unusable. Web pages that would take seconds to download now take minutes and the hard drive starts churning and grinding away. The whole system becomes slow and sluggish, and when I do a "top", Firefox is right at the top. Very often the only way to get out of this is to physically turn the machine off and then back on again, which I know is a bad thing.
Its not as if I am overloading Ubuntu. The last time I had to switch the PC off, all I had running were 2 terminals, a calculator and gedit. Firefox was running about 10 tabs. Even when I do a kill -9 pid on firefox and then restart it, within minutes, the system is grinding away and slowing down. The only way to remedy this is to switch the PC off. Someone else who had this problem says its as is Firefox is getting tired and needs to refresh itself completely. Is there any solution to this problem as I gather others have been experiencing it.

I recently built a pc to run 10.04 and EMC2 from linuxcnc.org I havent even gotten to the point of trying out EMC2 on this machine because Ubuntu runs so slow. The build spec's are as follows:
http://www.geeks.com/details.asp?inv...714-CEL24-PB-R MS-6714 mobo
Intel 2.4ghz celeron processor
2x512 PC-3200 patriot ram
using integrated graphics
40gb Maxtor IDE hd
I installed using the live CD downloaded from linuxcnc.org and Ive used that same cd multiple times so I know that's not my issue. Now to my problems. The computer runs, just very very slow. Opening 2 web pages at the same time takes 2-3 minutes, and if there is a lot of pictures or content there's no point in trying. Running EMC2 works ok, but if I open a complex program in the viewer all bets are off.

Since 11.04 was released, I've used it in Gnome and now also KDE, and this problem is in both. Aptitude is completely unusable. The main issue is that when downloading packages, it disconnects every minute if not every half a minute, making package installing a very hard process and making the configuration of a new OS take days (just to install 1GB of packages). Ontop of the disconnections, aptitude doesn't even want to go full speed when it IS connected.
The other issues involve repositories. Whether it's the official Ubuntu package servers, ANY of its many mirrors, or even my own custom PPAs, connecting to ANY repository when I reload my packages is a hit-or-miss, and it's completely impossible to get them all in one refresh (in fact, I don't think I've been able to access the main server since upgrading. Ever. I've been on the US server). This makes installing all of my packages take even LONGER. Also, to add insult to injury, the list files in /var/lib/apt/lists constantly corrupt themselves and make themselves unusable, ESPECIALLY the PPA lists (anything that uses launchpad has to be disabled at all times unless I have to update its program, or else I have to delete those list files every day).
Googling any of these issues separately gets me nowhere, so I'm making a topic, and it better not be the millionth topic I've made here that never got solved. The problem can't be my router or modem because my brother runs aptitude just fine on his 11.04 laptop. This issue is within my computer.
I meant apt-get. You mean they aren't the same program with two ways to run them? Yes, apt-get is the problemed one. I never actually type "aptitude" into the Terminal. As a consequence, Synaptic and KPackageKit and any other apt-get-using program is messed up as well.

this time last week I was happily running 10.10. I decided to upgrade to 11.04 via Update Manager (not a fresh install), and of course I didn't like Unity so gave Gnome3 a shot.
Well.. at this point the system would stall whilst booting.. so I downloaded the 11.04 disc and reinstalled it (I desperately need to keep my data and don't have any backup options at the moment).
But, now when I boot into Ubuntu (using an Acer Aspire 5741), the resolution is about 800x600, and the mouse doesn't work. Has anyone got any ideas how I can force Ubuntu to reconfigure the system as if it was a completely new install?

I have an old Dell desktop that normally runs XP. It has 512mb of ram and I think its a Pentium processor. From what I understood Linux is a simpler, and more stable and efficient OS so I figured I'd give it a shot. First I tried the Wubi installer and got nothing but error messages after the install and it kept freezing and eventually just wouldn't boot at all. So then I tried the full install from disc. Better at first. I soon discovered all the customizable themes and went a little nuts trying to make one user exactly like W7 and the other exactly like OSX leapord just for fun.
I noticed significant slow downs and after some research I came to find that it was taxing my old graphics card. So I setup a user with no changes, still really slow. Then I deleted and reinstalled and I'm now using the bare bones UI. Its still really, really slow. I get lots of mouse drag and just now it took about 7 seconds for the applications window to drop down and 35 seconds to open the home folder. Also about 10 seconds for right click window to drop down.
I'm trying and I really want to like Ubuntu but as of now I'm finding it unusable for even the most basic of computing. I realize my computer is old but xp still runs like gangbusters. So maybe Ubuntu is designed for more modern hardware and more ram, am I screwed? I was looking forward to playing around really customizing my GUI but more importantly I was planning on putting on my girlfriends laptop with similar specs. Her computer needs a reformat but she doesn't have the XP disc. As it stands her XP is still much more usable even with all the viruses then Linux is as a fresh install on my desktop. I don't want to delete xp and end up with a slower linux.

I'm using 9.10 Desktop 64bit on a Dell Latitude D830. I have 4 gigs of RAM and a 7200 rpm sata hard drive. Everything works pretty well, video, sound, and network. Flash isn't as smooth as in Windows but I assume that's a Flash/64bit thing and not necessarily an Ubuntu thing.
However, one area of performance still lags far behind my Windows XP experience, and that's disk writes. For instance, when I'm copying a large amount of information from a USB drive or from my Windows partition to my native partition, I can barely switch windows until the task is complete, nevermind trying to surf the Web. I thought that that might be related to the slow performance of the ntfs driver, but recently I have been doing a lot of work with VMWare, and I get the same result when trying to pause virtual machines - it writes a largish amount of information to disk in a short amount of time and I can't do much until it finishes.
Here are some things I looked at based on other threads to try to debug my issue:
~$ sudo hdparm /dev/sda
/dev/sda:
multcount = 8 (on)
IO_support = 1 (32-bit)
readonly = 0 (off)
readahead = 256 (on)
[Code].....
That disk read speed is a little faster than average - several more tests showed it hovering around the 66 MB/sec range. Of the other info, I see that UDMA is on which I understand is good, but if there is something else there that I should fix I don't see it.
I know that my computer can handle these tasks (at least the vmware stuff) without such a significant interface slowdown because in XP I did it with less RAM than I have now. Is this just the way that the linux kernel scheduler fails to account for UI needs?

I've been using UNR since the 9.04 release on my Eee 1000HE and have been generally happy with it as a solution since then. Tonight I've upgraded to 10.04 using the package manager and everything starts correctly but when I start any application it minimises itself straight away making the system unusable. If I click on the application to bring it to focus, I get about 1/2 a second of typing before it minimises itself again. Using that method I've been able to get around the problem with a sudo apt-get remove netbook-launcher - but I like the netbook launcher and I'd like to keep using it.

I've installed Ubuntu 9.04 on my hard drive. The results are worse I keep getting segmentation fault errors, black screens, lock ups, etc. This time I can't get it as stable as on Wubi. It can't stay stable more than 3-4 minutes - then the interface blinks and goes to black screen or shows weird colored strips/squares, locks up or shows tons of errors in the terminal. I did the kernel recovery mode partition check, no errors were found. I installed 9.04 on my harddrive, everything works fine, I log in and it stays great for about 1 or 2 minutes, then it freezes.
It shows the terminal with 'segmentation fault' errors, or goes to black screen and locks up. Alt+SysRQ+B is the only solution and sometimes it doesn't work either. I got Ubuntu 9.04 running through Wubi before and it ran perfectly stable occasionally on few boots. But I can't get it like that on my hard drive installation It just keeps crashing. I did a long memtest (10 tests passed), ubuntu file disk check went fine, my current operating system Windows 7 runs great and another Live CD Linux based system like Knoppix runs perfectly stable. Should it be a driver issue?

I've just installed BitDefender on my 10.04 netbook, updated and activated it, completed a scan, and found Backdoor.Generic.284566 The thing is, it won't let me delete/quarantine the nasty. BitDefender does give me a warning about my screen resolution being too low (800x600), i believe this may be the problem. The option buttons are not visible on the screen, therefore I cannot use the program properly.(i tried the max resolution 1024x600, but to no avail )
