A workaround seems to be disabling 'kernel mode setting'. (https://wiki.ubuntu.com/X/KernelModeSetting)
Since I am a clueless user ;-), I am not sure how to do this. I tried these two things: 1. execute this command (as root): echo options i915 modeset=0 > /etc/modprobe.d/i915-kms.conf 2. edit /etc/default/grub; change the line starting with GRUB_CMDLINE_LINUX_DEFAULT to GRUB_CMDLINE_LINUX_DEFAULT="splash quiet nomodeset" and then: update-grub -- You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xf86-video-intel. https://bugs.launchpad.net/bugs/528467 Title: [i855] GPU hung (drm i915 intel) on Lucid Lynx _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
