Arch Linux over time Screen jitter then black screen
 

Hello everyone.

I've been a happy Arch Linux user for years now.

Recently, on my eee 1000he (an Atom netbook with intel GMA graphics) I've been seeing strange things.

After it has been on for some time (usually hours), the screen starts to jitter, just for a fraction of a second, every now and then. After this has happened some times, the screen goes black (one time it went red). The backlight is still on and I can still ssh to the machine which reacts normal appart from the black screen.

I can only regain the screen when rebooting.

What could this mean? Is it hardware or software? X logs don't shown anything weird, where should I look? I haven't found anyone with the same problem on the net.

The fact is that this post is my last resort before reinstalling and hoping it is a software issue...

Do the problems occur when or shortly after the screensaver or power management kicks in. If so, that might be why.

It SOUNDS like a hardware issue though.

I'm pretty sure Asus sell the netbooks with Linux, so maybe you could contact them?

Thanx for the response... I have downgraded tot kernel 2.6.31 and I haven't had the effect since!
(happy it's not a hardware problem (so far))

now I'm back to losing my internet connection upon wakeup :) http://bugs.archlinux.org/task/17183?opened=3787&status[0]=)

2.6.32 is not treating me very well, I also posted this:

Anyways... I'll just wait for 2.6.33 then ;) and in the mean time look for correlation with powermanagement events.

Perhaps it is this:

Lets hope, it explains (as far as I onderstand) why it happens after some time...

I know now for a fact that it only happens after the laptop has gone to sleep once after a reboot. So it is software and it is powermanagement related.

I posted a bug report:

Hope some people have the same problem and it will be solved...
