Matteo, I had the exact same experience yesterday and filed this bug: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/320525
I also mentioned it in #ubuntu-x and they said it will be fixed as soon as intel xorg ddx driver 2.6.1 hits apt. Indeed this morning I got new updates and they fixed my black-and-white screen corruption issues and my machine is not bootable again. Now let's try to confirm that the drmWaitForVBlank bug has disappeared with these new versions. -- [g45] jaunty X "EQ overflow" infinite loop hang https://bugs.launchpad.net/bugs/305979 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
