Ubuntu Installation :: Random Logging Off Since Lucid Upgrade
May 18, 2010
Just upgraded from Karmic to Lucid using auto upgrade on Thinkpad T42. Since doing this, I am experiencing random logging off. Suddenly, I get dumped to the log in screen and need to log back in. A search in the forum suggests this was a problem that some people had with Karmic, but is now fixed (I never experienced it with Karmic)
It seems to be associated with Firefox, with it not happened since switching to Chrome, but switching back to Firefox has just resulted in me being logged off. This could be a coincidence of course. This is rather serious problem as I use the Thinkpad to give presentations
1st post @ LQ. Ubuntu user since 2007ish. Lots of PC experience... now vexed by upgrade from 9.10 Karmic to 10.04LTS Lucid.
The problem: random freezes whenever I boot into Lucid as user through usual Grub menu. The freeze sequence is: 1- screen stops, 2- mouse pointer freeze w/ no effect on click but moves freely and keyboard is useless, 3- screen blacks out for about 30 seconds and then returns but is unusable and 4- constant HDD activity for about 5-10 seconds. I have waited several minutes for a recovery of some sort but no dice. I reboot via on/off or reset button. Ubu deletes 2 inodes and then I'm off and running again.
If I boot through the recovery console there are no problems at all. The recovery console sequence: 1- select recovery from Grub menu, 2- at recovery menu select drop to root command prompt, 3- give root password, 4- enter 'gdm' at console prompt, finish boot up in my only user desktop (not root.)
I have not been able to find any log files that show an error message, but I'm not so tech oriented that I would necessarily know one if I saw one. Through many hours of browsing posts describing Lucid problems @ UbuntuForums (one of which has over 1,000 responses) I have found my '.xsession-errors' file (attached) is full of data.code...
I am using Ubuntu Lucid Lynx 10.04 (64 bits) in my Asus U30JC laptop (Core i3 M350, intel 4500MHD + nvidia 310M with nvidia Optimus, 4GB RAM). I am content with Lucid and I don't want to upgrade to 10.10 for now. However I read that the new 2.6.36 kernel has some good improvements, such as improving system interactivity while intensive I/O (such as copying large files), and improved energy management for i3/i5 processors (which I hope translates into more battery time, which is a problem of Ubuntu vs Win7 in my laptop).
I discovered I had 2 options: compile the kernel myself, or use the Ubuntu Kernel PPA (maintained by the Ubuntu Kernel Team). I decided to use the PPA, so I added it to my software sources and installed the generic"linux-lts-backport-natty" kernel (2.6.36-1).
Package installation went fine, and after reboot, I could log in to the desktop no problem. Everything seemed fine, but after a few minutes, the system freezes completely: mouse did not move, none of the indicators moved, even Ctrl + Alt + F1 did not work.Where is the log file where there might be a message related to the freeze? Do you think that the kernel developers would try to fix a bug that probably only affects people running the 2.6.36-1 kernel on a distribution that was not built around it?
Why is it that about 98 to 99% of the time my computer will boot to Ubuntu/Lucid just fine but on rare / random occasions after seeing the initial BIOS boot screen and initial cursor just after initial BIOS boot screens, the video will just go BLANK, i.e. does not boot to Ubuntu desktop ?
If I then do ALT,CRL,DEL sequence the SPLASH screen is displayed on the monitor and the system then reboots and then goes thru the complete boot process all the way to the desktop just fine.Why this occasional failure to boot completely to the desktop ?
Ever since I upgraded to Ubuntu 10.10 on my laptop, I've been having this problem. Every now and then, for seemingly no reason at all, the screen will go black and after a few seconds I find myself at the login screen. I've kept track of when it happens and there is seemingly no pattern to it; sometimes it will happen when I'm watching a video, sometimes it just happens when I'm browsing the internet, and sometimes it happens when I'm not doing anything.
As per the title, really. I've upgraded to 11.04, ran updates, but I can't stop LottaNZB randomly crashing out. It will be running fine one moment, then 'zap' it disappears. I've tried going through the apps running at the same time, and there doesn't appear to be any pattern. In fact, I've left it running with nothing else open and have returned to a computer with no running apps. Sometimes, however, it will run fine for several hours, completing all of it's downloads, although this is pretty rare. LottaNZB's logs appear to wipe after a crash (unless I'm missing something) so I'm none the wiser why it happens. Has anyone got any ideas what to try next? It ran faultlessly on Ubuntu 10.x
After upgrade to 10.04, my disks are randomly named (sda, sdb, sdc) at each boot. My drive labeled "XP" is sometimes named "sdb" and sometimes "sdc", while my other drive "DATA" is respectively "sdc" or "sdb". This wasn't the case before upgrade with KUbuntu 9.10.
Due to this random naming, my auto-mount in fstab often fail at boot time !
Any solution for this (not found here by myself) ?
Is this linked to Grub troubles reported many times here ?
I upgraded from 9.10 to 10.04 2 weeks ago. After a day or so I suddenly couldn't logon anymore. The pc boots, I get the userlist and can enter my username and password, then the userchooser dissappears but the background stays purple and nothing happens anymore. I can still move the mouse and switch to text console but I don't get my desktop. This happens for any user even a new user I created from the command line just to test this. In the end I assumed I messed something up during the upgrade and reinstalled the pc from scratch using Ubuntu 10.04 32-bit.
I was happy for almost 2 weeks but now suddenly I get exactly the same problem. No matter which user account I try I just can't logon (graphically) anymore. Rebooting the system doesn't help. When I run top on a text console I don't see anything hogging the cpu. There is nothing obvious blocking anything. I can't find any clue in /var/log/* or ~/.xsession-errors. I can logon still in text mode as a regular user, my homedir is there, everything looks ok. 1 thing I did notice is that a (few) boots before this started happening autofs suddenly didn't start anymore at boot time (my homedir is mounted from a NAS via NFS). I had to manually start autofs as root to be able to get to my homedir. However this seems to be ok now, automount is running and my homedirs are available. I tried making a new user with a local account just to rule out network issues but even this user can't logon. So the automount issue may be totally unrelated.
It seems that my Ubuntu 10.04 (clean install) to randomly freeze / hang (mouse/keyboard unresponsive, only a hard reboot is available as option) but with no garbled screens/windows/etc. There's no pattern why or any application that could be responsible. It could happen ten minutes after it is started or after 2 days but at some point and suddenly the system will become totally unresponsive, freeze and hang up. I used the same PC with Karmic Koala and releases before that (sometimes on for days) with no such problem so it shouldn't be a hardware problem.
I thoroughly check system logs after the hard reboot (System > Administation > Log File Viewer) and there's no entry around the time of each freeze / hang to pinpoint me to something.
The only thing that is certain is that the following errors / warnings always appear in .xsession-errors file:
Here is also some info about my system: M/B: ASUS P4R800-V DELUXE CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz RAM: 1GB Graphics: ATI Radeon 9100 IGP
Since upgrading to lucid, I have been experiencing regular system lockups. About once a day, my X desktop will disappear and I'll see a TTY with a few old console messages and at that point everything is completely frozen and I must hard reboot.
I have checked out various logs in /var/log and found nothing at all that indicates the system knew anything bad was happening. What is the correct approach to try to narrow this down?
I want my Ubuntu 10.04 to login to an Xterm session every time, so I changed it to auto login to Xterm in the login screen settings. This worked fine until I went to do something in a gnome session again, and now even though it is still selected as logging into Xterm automatically, it logs into a Gnome session. Can anyone help me with fixing this?
I'm currently upgrading my laptop, and it has completed the step "Getting new packages", and is now onto "Installing the upgrades".It says it is going to take another 2.5 hours, but I am leaving work soon and want to take the laptop with me. Is it safe to disconnect it from the internet at this point? I don't want to fudge up the install, but I don't want to have to leave my laptop at work all weekend (or have to come back and pick it up at some point).
I upgraded successfully last night from Hardy Heron to Lucid Lynx, but have no sound now. After searching around I can see that this is a fairly common problem. But none of the proposed solutions that work for other people have yet worked for me.
If I type 'alsamixer' at the command line, everything looks fine. There are no 'MM's indicating something being muted. I tried removing and reinstalling alsamixer and pulseaudio with no success. Edited lines 45 and 46 of /etc/pulse/default.pa with no luck.
I have a dual boot system with Win XP and Ubuntu (using grub boot menu). I recently upgraded my Ubuntu from 9.04 (Jaunty) to 10.04 (Lucid) and now I cannot boot into Ubuntu - I just get a desktop with no icons or disk activity. I think this may have something to do with the fact that I answered 'no' when asked whether to replace my menu.1st file, and possibly some others. So my boot menu still refers to 9.04.
I can't upgrade from Karmic to Lucid,If I try to use the update manager I get a message that says "Can't download release notes. Check your Internet connection". I've tried changing the repository and I get the same message, but I can log in to the Internet, and download and install any program from the repository. I also get regular updates for Karmic so the repository is fine.I tried the command line
~$ sudo apt-get dist-upgrade Leyendo lista de paquetes... Hecho Creando �rbol de dependencias
I wonder if others have upgraded their Lucid kernel using the deb [URL]..repository. I have been using the repository for some time now without any apparent problems, and have gone from 2.6.36-1, through 2.6.37-10, and am now on 2.6.37-12.
All of these seem to work with no problems at all, but I am just wondering if other users can also report success, or if there are any trip-ups that might occur. I still keep updating the "standard" kernel from the main repos, ie 2.6.32-27, so I have that as a backup, but I'm just very curious about other people's findings.
I read recently about security flaws in the ubuntu kernel, and when I checked my kernel, it is 2.6.32-29-generic. I looked in synaptic, and I have the linux-generic meta-package - which should ensure upgrade to the latest kernel, and yet this is not being updated when I run update manager. There is a linux-image-2.6.35-25-generic, but the advice is not to install this directly (to avoid breaking dependencies, etc.), but to install the meta-package instead. Yet, the meta-package doesn't seem to be doing what is should do.
I'm running Ubuntu 10.04 Lucid Lynx Desktop Edition and most of the time I get these random freezes and then I have to turn off my computer and reboot it back on. It's getting really annoying because I am constantly downloading huge packs of data and it freezes and then I have to start re downloading...
Right after I type in my username and password and hear the usual login sound I have to wait about 15 to 20 seconds to get the X desktop. The system load average monitor is at its max and starts to become lower.If I log out and in again I dont get that delay. It only happens with logging in after a reboot/power on.I tried to open a console (Ctrl+Alt+F1) before I log in, move back to X and login then jump to console and use htop to see what's eating up my resources during that time with no luck. Everything seems to be normal.
After upgrading from Karmic to Lucid, no wireless networks are found on my computer�an acer travelmate 5510. On Karmic, wifi worked flawlessly "out of the box"�no windows drivers or anything needed. I have checked under Administration/hardware drivers; it tells me "no proprietary drivers are in use on this system." Cabled internet access through my wifi router works fine. How to get wifi up and running under Lucid. Despite having used Karmic for a while, I am relatively new to the inner workings of Ubuntu / linux systems, and really don't know where to go from here.
I have an AMD64 system, which I recently upgraded to Lucid 10.04. The system now fails to boot after the upgrade. Recovery mode makes no difference.
When I attempt to boot, I get a series of messages about file systems needing checking, and also some messages from ureadahead-other. (process terminated status 4), though a post here says that status 4 is in fact not an error.
I have sucessfully booted the Lucid desktop install CD in live CD mode, mounted the filesystems, and started parts of my system in a chroot. In that system I tried running an update, and removing plymouth, but it made no difference. how I can get my system working.
I did take a backup of /etc before I upgraded, so I could get back to a karmic install, but the pain in doing so would be considerable, so I would prefer to avoid that if possible.
I made the mistake of trying to upgrade my Karmic (server) installation to Lucid earlier today, after which I've been unable to boot into my server. The server is on OVH, so I can't watch it boot, but I am able to access all of the data from the filesystems via rescue mode. I ran fsck and that came back clean. I also ran the boot info script, the results of which are below.
I know my best bet is to backup what I can and do a fresh install, but I won't be able to back everything up so trying to get this working would certainly be more convenient. I'm sure I'm leaving out useful information, so let me know and I'll post it.

Upgrade to lucid (by running update-manager -d) succeeded with no major error. But when I reboot the computer, the boot splash screen is "Ubuntu Studio" and the login screen's background is a "Ubuntu-eee" png picture. A funny mess.I was able to get to the new boot splash screen by remove --purge ubuntu-studio, which I must have installed sometimes in the past, but I don't see anyway of getting the new theme for the login screen.I have this eeepc for about 2 years and never have to fresh-install Ubuntu except the first time. I much rather not have to fresh-install just to solve some aesthetic problems.I am pretty sure it's due to some package I installed in the past, but I don't see any Ubuntu-eee related package in Synaptic either.
A few days ago I made the mistake of upgrading to Ubuntu 10.04 LTS, and subsequently had nothing but trouble. My volume icon disappeared and for the life of me I couldn't find it or reinstall it. An eerily Windows-like chat icon has appeared next to my login name that I didn't ask for, and more importantly my handbrake program (Matroska encoder) completely stopped working.
I've learned in the past that LTS editions are not normal upgrades, and I should best avoid them. But this one appears from the Ubuntu homepage to be the standard upgrade from Karmic to Lucid. I've had to completely reinstall Karmic on my workstation just to be able to carry on as normal, but the laptop seems to be coping ok with the LTS edition. Can anybody tell me if this LTS is now the default upgrade for Lucid, or is this just a regular LTS and I should wait for my standard one to come out?
