Same here for Ubuntu LTS 12.04 (updated), i686, grub-pc, AMD Radeon X850 XT graphics card. Monitor is a VGA-connected BenQ FP202W that never caused any trouble with typical resolutions like 640x480, 800x600 etc.
Workaround: Tell grub to stick to ascii terminal instead of graphics mode (uncomment "GRUB_TERMINAL=console" in /etc/default/grub ) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/767092 Title: Grub gives graphics card invalid data To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/767092/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
