I am new to Linux/Ubuntu. Any input is greatly appreciated.

I am using Ubuntu 12.04 on an eeepc 1101HA. Using the Intel GMA500 "Poulsbo" video hardware.

The display graphics are fine at all times when I power on the computer fresh, but as soon as I close the lid or suspend from the cog menu and I wake up the computer, it looks like this:

distorted screen

Every second line of pixels is black, the display seems to be on a angle and repeated 3 times, and the middle section works for clicking and interacting with the mouse. Everything works normally, it just appears to be the graphics. Will this problem be solved if I install an older version of Ubuntu like 11.10?

Any insights into where I should be looking/reading up on how to fix this are greatly appreciated.

It seems I got this symptom fixed by following instructions from Ubuntu wiki.

Relevant part here:

Fix suspend

If suspend does not work for you, there are various quirk options you can try. See the manpage for pm-suspend for a list of them all. One that has been reported to help is quirk-vbemode-restore, which saves and restores the current VESA mode.

To test it, open a terminal and use the following commands

sudo pm-suspend --quirk-vbemode-restore

That should suspend your system. If you are able to resume, you'll want to configure UBuntu to use this option every time you suspend. To do this oOpen a terminal and use the following commands:

gksu gedit /etc/pm/config.d/gma500

Add in the following code and save the file:
