Desktop freezing

Postby moodywoody on Fri Nov 13, 2009 11:29 pm

Hi folks,

I hope you can help me with an annoying problem that just crept up.

A couple of days ago I reinstalled Mint 7 on a Dell Latitude 6300. System is fully updated, not a lot of stuff installed (most notably Virtualbox, some small stuff, no desktop candy whatsoever). Since then it has happened already half a dozen times that the desktop completely freezes. Mouse pointer can be moved, programs seem to continue to run (music plays on), changing volume and screen brightness with laptop function keys is also ok - but nothing else. No input is accepted, neither ctrl+alt+backspace nor REIBUS work. I can only go for a hard reset.

I've checked the log files but didn't see anything interesting.

Before I reinstalled Mint, I ran a Mint/Vista dual boot combo on the same laptop. I never encountered this problem, so I doubt it's hardware related.

Let me know what kind of info you need.

Any ideas appereciated,
Cheers

Sounds like a graphics issue, but it would be good to post your hardware list. Terminal : inxi -v 4 , copy/paste the output back here.

I fail to see what the problems mentioned in that thread have to do with mine.

Well, if you don't think it is a graphics issue, I won't bother you any more . . . just tryin' to help.

Excuse me for not understanding immediately what video performance/full screen problems have to do with a freezing desktop. I'd just much rather try to get a grip on where the problem is actually located (possibly with some sort of process monitoring tools or whatever) before trying out random stuff.

To whom it may concern ... after reading up some more (in particular starting here https://wiki.ubuntu.com/X/Troubleshooting/Freeze ) I changed a section in my xorg.conf from the basically empty

Code: Select all
Section "Monitor"
   Identifier   "Configured Monitor"
EndSection

Section "Screen"
   Identifier   "Default Screen"
   Monitor      "Configured Monitor"
   Device      "Configured Video Device"
EndSection

Section "Device"
   Identifier   "Configured Video Device"
EndSection

Section "ServerFlags"
   Option   "DontZap"   "False"
EndSection


to
Code: Select all
Section "Device"
   Identifier "Configured Video Device"
   Option "AccelMethod" "exa"
   Option "ExaNoComposite" "false"
   Option "MigrationHeuristic" "greedy"
EndSection


(rest unchanged). In the last fourteen days I did not observe another freeze so I assume this did the trick.
