View Full Version : [ubuntu] Kubuntu hangs randomly

June 29th, 2009, 03:11 PM
Hi all,

I am relatively new to kubuntu.

Recently my kubuntu kdm hangs randomly. It happen so randomly.

When it hangs, everythings does not work except the mouse. I can move my mouse but cannot click anything. I cannot also ctrl+alt+F1 to switch to terminal mode.

Can anyone help me with this. I cannot reproduce the hang exactly. Sometimes it happens when i do only small things.

When you reboot, you'll need to look at the your logs under /var/log (probably using sudo tail /var/log/syslog and sudo /var/log/messages). Also look at the output from dmesg | less. You may see a message indicating what was going on at the time of the hang, and you can start trouble-shooting from there.

If you can post what was running at the time of the hang, that would also help. Which version of Kubuntu is this?

This is a big and well known problem in 9.04. I am guessing you have an intel integrated graphics card? Kernel updates have improved the issue somewhat, but it is still an issue, and still has open bugs associated with it. Best option is to disable desktop effects and hope they fix it soon.
