I have a computer that i didnt turn off, simply put
in suspend mode. But i
found that sometimes ( i dont know when or why) kdesktop go away.
The symptoms are:
- the fan speed up
- two KDESKTOP process take 80% of cpu each one,
- The icons on desktop are not clikable anymore
- the shutdown button on first call open the dialog and i can make click on
suspend
- the shutdown button on second call do nothing.
Pressing ALT+CRL+BAKSPACE i go to login and everyting works again... for one
hour, 1 day or one week (randomly)
I have opensuse tumbleweed.
A common suggestion is pop open a terminal window and run top or htop.
Often that will show processes using too many CPU cycles.
Might also want to note if any non TDE software is running. The other
day I saw this and my laptop was getting quite warm. If I remember
correctly I was running two krdc sessions concurrently, but I don't
remember if I was using TDE or KDE krdc.
Another approach might be to not suspend the computer. See how often the
runaway issue arises. Not suspending removes one variable from the equation.
Another approach when the desktop becomes unusable is toggle to a
console with Ctrl+Alt+F[1-6]. Log in as root and run top or htop. Kill
any suspect processes and see if that restores desktop usability. If
unfamiliar with using alternate consoles, then practice a bit when the
system is running okay to get the hang of toggling.
Another option, if available, is use a second system to SSH into the
problem box and repeat looking at processes with top.
These types of strategies should reveal whether the problem is the
operating system, desktop environment, or something else.
On a less pleasant note, I have seen hardware cause similar issues. I
have seen systems where the desktop eventually freezes and no amount of
troubleshooting or wizardry finds a remedy. The solution is replace the
motherboard.
I hope that helps. :)
