I have the same issue running DELL Latitude D430 with Intel Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller.
I can confirm, that SNA workaround fixes the issue. $ cat /etc/X11/xorg.conf Section "Device" Identifier "Card0" Driver "intel" Option "AccelMethod" "sna" EndSection -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745608 Title: [915GM] font corruption on Intel GMA900 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/745608/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
