[FIXED] Suspend To Ram (Garbled Display; weird fix)

[lingwitt]

Hello,

After waking up from Suspend to Ram while in X, only the top 4th of the screen is usable; all of the screen below seems to be the last correct line of pixels stretched to the bottom of the screen; the screen doesn't even show up when I'm not using X.

I noticed that I can return the screen to normal by doing a standby and then waking the computer up again. For instance, I issue this at the command line:

echo -n mem > /sys/power/state; echo -n standby > /sys/power/state

Then, the computer goes into sleep mode S3.
When I push the power button, it wakes up and then immediately drops into S1.
I push the power button again, and it wakes up in perfect condition.

What's the deal? Thanks.

Come on guys!

55 pairs of eyes on my post and no one knows anything?

I needed to do VBE POST and reset the VBE Mode.

The trick was to use OpenSUSE's s2ram.

My machine requires:

s2ram -fpm

but I simply modified the code for my machine.
