I left a rig of 6 video cards running poclbm on ubuntu 11.04 overnight and everything went fine...

I left the same rig running all day today and found that my mouse was "jittering" in the lower right side of the desktop, the desktop was still visible, presumably active... but my mouse was frozen to a section of the screen and the miner terminals seem to have stopped working (not updating anymore).

Any solutions for this?

Does anybody even know what's causing it?

Could it be their temperatures? Some cards are approaching 80-85 celcius when mining... perhaps just heat adding up near the rig over time?

do you use DE on you Linux box[aside Xorg itself]?
no Compiz/Plasma was running[interfering/competing with mining sofware GPU loading in interface rendering]?
and yes, temperatures above 80'C is bigger than perfered. try keep it under 75'C-70'C. add/replace more case fans, invest in watercooling and etc.

The mouse moving around by itself shouldn't freak X out. Are you running Ubuntu 11.04? I saw something about turning off multiple desktops or if the mouse hits the edge of the screen it will flip desktops and impact mining. If it's a usb mouse, just unplug it and see if that makes any difference.

It's more likely heat, power, or the fglrx driver freaking out.

I imagine the mouse jittering could be caused by power issues, which could be exacerbated by heat.  Otherwise, I see terminals stop updating after a while too so that's normal under heavy graphics usage.

I am fairly certain it has to do purely with temperatures now guys...

I tweaked the cards a bit to guarantee their temps stayed below 75 celcius and the rig ran fine overnight.

If any one of the cards rises above 85-90 for too long though this seems to happen :S

I thought GPUs were smart enough to automatically shut off after getting too hot?!

What GPU's are they? When I first got mine and they were pushing 80 C I started getting worried about temps so I searched for it and from what I found, most 5850's internal cutoff doesn't trigger until 100 C or more even though it is generally recommended to keep them below 80 C.

They are 5870s, from all different manufacturers.
