Ubuntu 9.04 often/random GUI hangup requiring reset


The problem manifests itself randomly.
Sometimes when I move the mouse towards some action point (random), GUI hangs up: mouse does not move any more. Can't Alt PrntSub REISUB, nothing works except turn machine off.
From Xorg.0.log:
(II) Module synaptics: vendor="X.Org Foundation"
compiled for 1.6.0, module version = 0.99.3
Module class: X.Org XInput Driver
ABI class: X.Org XInput driver, version 4.0
(II) Synaptics touchpad driver version 0.99.3
Thanks

Sounds to me like a Hardware problem. Not necessarily overheating. Might be faulty ram or something else. Plug in some Linux Live distro (Ubuntu, Knoppix) and let it run through a RAM rest for a few hours. If it crashes (hangs) there too, you surely can assume that it IS the hardware.

The computer (a laptop - Dell Inspiron 8200) does cycle the fans with some frequency, but it quietens if no flash activity is around the many firefox windows I have open. On the terminal 'top' shows 35% with 114 tasks running, 2 running, 0 stopped, 0 zombie;
I will run the memory test.

In the hangup situation none of the aforementioned keyins work. Only forcible power off.

I have done a memory test with no errors. The machine is now quite hot from running the test; the fans were at maximum; they have receded somewhat now; now after 5 minutes back to silence!.

The hangup is so annoying that I am considering going back to Suse (never had any problems with that distro).

I hope that I can resolve this issue which started with my last reinstall of 9.04 which was forced on me after I tried 9.10 with many UI problems (reported to the forum with no help). The problem seems to be in the update that Xorg applies soon after reinstallation.

Thanks for your help.
