Graphics freeze until mouse or keyboard input.

[r0gue]

It's not the screensaver, I have that disabled and 'Regard computer as idle' set to two hours (the maximum) yet still the problem persists.

After a few minutes without keyboard or mouse input the graphical output from most programs just stops. It remains paused until I use an input peripheral whereupon it refreshes, showing that it has been running beneath all the time. Eventually though, in many cases, the processing of those programs appers to stop too not too long after (minutes).

This happens...

When I play DVDs - the picture just freezes (the sound continues for a while)
When I play youtube video's - the whole thing just stops playing mid stream.
When I run large verbose rsyncs - the command line stops scrolling
When I run programs I have written myself - likewise
In FF with sites like Jango it finishes the song I'm playing then pauses indefinitely

In short, everywhere with every program. The length of time it takes to kick in seems to vary from 20 seconds to 15 mins with the shorter being more typical in command line programs.

My setup is a fresh install of Jaunty on a P4/3000 that has been running Hardy quite happily for about a year (and indeed still runs it fine if I swap that hard drive back in) so I've ruled out hardware problems.

I suspect the issue may be with power management or the new Xorg but the gnome interface seems to offer little in the way of options for either of these subsystems.

Has anyone else suffered a similar problems If you solved it what was your solution? If not, then does anyone know of a program that will periodically wiggle my mouse for me so I can at leave tasks running overnight and watch DVDs without having to get up every 10 minutes?

Cheers,

Roger.

Really no-one?

sounds like graphics issue, what is output of this

lspci | grep -i vga
grep -i driver /etc/X11/xorg.conf

I ask, because if it is intel based, there is a bug in the intel graphics driver, there are some work arounds.

Thanks for getting back to me

Yep, it's an Intel (output below)

As that's the case I wonder if the other problem I'm having might be related too... Google Earth is dog slow i.e. 3 second refresh, locks up for long stretches etc.

Cheers,

Roger.

r0g@steppa:~$ lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)
r0g@steppa:~$ grep -i driver /etc/X11/xorg.conf
r0g@steppa:~$

I should mention though that's is a vast improvement over Google Earth in Hardy on the same machine which used to restart my x session with zero warning every time I tried to open it!

Post the contents of /etc/X11/xorg.conf file here.

That seems to have sorted the freezing problem, it's not done it for a while now at least.

It's made Google Earth even worse though, crazy graphics corruption everywhere but I've got an old windows box I can run that on when I need to so I'm not so fussed now. The thing that's troubling me is xorg's CPU usage ~ idling around 55%. That might be to do with me enabling Option "AccelMethod" "XAA" in my xorg.conf as several of those posters suggest so I'll get rid of that and see if it improves. If not I'll post back with my xorg.conf file - even though it looks pretty sparse.

That seems to have fixed it (I didn't notice any improvement with it on anyway). So thanks again, it seems backward is the new forward!
