[Workaround]
As workaround add the option i915.powersave=0 to the kernel command line in the grub config (for GRUB 2: edit /etc/default/grub and add i915.powersave=0 to GRUB_CMDLINE_LINUX, then run sudo update-grub; for GRUB 1: edit /boot/grub/menu.lst and add i915.powersave=0 to the end of the line beginning with # kopt=, then run sudo update-grub).
