I'm also experiencing exactly this problem on a fully updated Debian testing system. It broke at about the point the kernel was upgraded from 2.6.32 to 2.6.38. I've not got any non-default grub options that I'm aware of. I've got a fairly old PCI Matrox G450 graphics card so no support for kernel mode setting.
Have you got any idea how I might fix it or diagnose the problem? Oliver -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
