Ubuntu – Graphical corruption of characters in File Manager or Terminal

12.04command linefilemanagerhibernateintel graphics

I'm using Ubuntu 12.04 LTS with graphic driver IntelĀ® 945G x86/MMX/SSE2. Sometimes (I think after using hibernation – not restarting system) I'm getting graphical issue with characters in File Manager or Terminal. I can't imagine what is the source of this problem.

Here is my desktop with graphical corruption, see text characters in browser is fine.

It appears to be a rather severe example of the intel text rendering bug that has been around since Natty Narwhal. The fix usually suggested is to insert the following into /etc/X11/xorg.conf:

Section "Device"
    Identifier "Intel"
    Driver "intel"
    Option "DebugWait" "true"

The Launchpad bug report is here.

It could also be this Intel/Xorg bug: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1005717]2 However that is markd "fix released". Make sure your Ubuntu is fully updated. Chris.
