Bug Description

Binary package hint: xorg

Hi,
I am just start work with linux and can not sure tell in which package bug.

Symptoms:
Xserver randomly freeze. Today it was frozen 5 or 6 times. It can happened in different situations. Some of them:
1) Working with Firefox
2) using Nautilus
3) resizing some windows
4) changing workspace
5) computer try to Sleep.

When System freeze usually mouse continue respond but some times disappear.

In all cases Combination keys:
1) Cntrl+Alt + RSEIUB work normally.
2) Cntrl+Alt+Backspase doesn't work but when system wasn't freeze this combination work good

I am using ununtu Jaunty 9.04 64 bit

Give this a try first:

Go to Applications > Accessories > Terminal

When the terminal window appears, type this command:

sudo dpkg-reconfigure xserver-xorg

Enter your password and follow the instructions on the screen. Let me know how it goes.

Hi Greg,
Thanks for your replay.
I did it. Everything was OK.
Cntr+Alt+Bs don't work anymore.
;) Absent flag "DontZap" "off".
I will try to use this for awhile and give respond after next freeze.

Maxim.

It didn't help.
After reconfiguring and restarting computer freezing not finished.

I found that xserver often freeze if computer was locked by timeout. Sometimes it ask password but after resume show only background without any panels. Sometimes it don't ask password it all, just freeze.
If I Suspend or Hibernate it resume normally.

I am using now only 3 programs: FireFox, Nautilus and terminal.

Answers on questions:
How complete is the X failure?
+ Does ctrl+alt+f1 take you to a console? NO
+ Does ctrl+alt+backspace restart X? When frozen NO in normal situation Yes
+ Does mouse pointer still move? USUALLY YES
+ Does the keyboard LED come on when hitting the CAPSLOCK key? YES
+ Can you ssh into the system from another computer? I don't have possibility to test it now but I will.

I used this:
When the crash occurs, press Alt+SysRq+1 (one, not L) followed by Alt+SysRq+t. If using a text console, you should see a trace dumped to the screen. If the system is sufficiently alive, it will also be logged to /var/log/kern.log and visible in the output from dmesg.

In this time xserver was completely frozen (mouse disappear). After this keys I used Cntrl-Alt-Del.
in attached file fragment of kern.log for current run.

Please anybody help me. I restart computer once per hour or even often.

Max, unfortunately none of these files show an error message or backtrace. No troubleshooting can begin until we know what the error is.

Perhaps they are in one of your files in /var/log/gdm/. Look in your :0.log.1, :0.log.2, etc. to see if it indicates an error.

The kernel is calling the "Out of Memory killer", "oom_kill_process". This means that your system has catastrophically run out of memory for some reason. This is not an Xorg bug, so I'm refiling to Ubuntu for better triaging.

Meanwhile, look into why you would be running out of memory. Are you running a program that uses too much memory? Is your hardware memory bad? Do you have enough of it? There are various programs, like 'top', which you can use to display memory usage and watch the memory use of different processes so you can learn which package has the fault.

Good luck!

Hi Bryce,
yesterday night i reinstall jaunty. I installed Alpha3 with hope that back will disappear. But It is not.
Now I have system by default except: I removed games, and install: CompizConfig Setting manager, and Gnome SWF player.
I left computer turn on overnight and at morning It was frozen. It show black screen but monitor wasn't switch off. In my power management I turn on screensaver after 10 min idl with screen lock and switch off monitor in 11 minutes.
It don't have mouse, don't ask password, it didn't respond on Alt+SysRq+R with following Cntr+Alt+Del.
after this I pressed Alt+SysRq+R1tseiub. It saved log and reboot.
In log absent messages out of memory but I don't know when it freeze really.
I will try to look on memory using.
I have now 3Gb memory.

Thanks

I can add that this error very often happen if computer was idle for awhile. But It is not error screensaver, I turned off it.

I installed Ubuntu 8.1 on Lenovo T500. It is randomly crash too. If ubuntu 9.04 after crash can save report (Alt+SysRg+1, t) and can be rebooted by (Alt+SysRg+RSEIUB) than ubuntu 8.1 just crash with blinking CapsLk.
Ubuntu 8.1 can be rebooted only by switch of power (Press and hold power button).

I have the same effect: randomly freezes. Today I had to do a reboot by switch of power (Press and hold power button).
I was running 9.04 32-bit alpha-4 to rc without problems.
After I was switching to 9.04 64-bit and it run ok. since two days I have this regurarly system freezes. I don't have a sure way to reproduce it, as it may happen during any situation (working by terminal, ...)

Yesterday now crash so far. It's running since 10h without problems, only using Rythmbox, aMSN and FF.

Today I had again a crash after about 30mins, only using FF. The computer was in the same state as the day before (suspended during night). After rebooting and comtinuing surfing, it crashed again. Today no flashing of Caps-Lock and Num-Lock

Sometimes after a reboot, I have the following behaviour of the network manager:
- No wireless connected and no wireless found
- Right click on network manager icon and uncheck [] Wireless
- Left click on network manager icon states now "Network Manager is not running..."
- Hoover over says "Networking disabled"
- Dmesg states "[ 355.720377] NetworkManager[4307]: segfault at 0 ip 00007fe07dab7c60 sp 00007fff88c27678 error 4 in libc-2.9.so[7fe07da37000+168000]"
