On the upstream bug the patches being proposed are kernel patches, so this seems to be a bug in the drm, thus I'm retargeting to linux.
It sounds like as a minimum, this patch is needed, once it's verified to fix the issue: https://bugs.freedesktop.org/attachment.cgi?id=34718 ** Package changed: xserver-xorg-video-ati (Ubuntu) => linux (Ubuntu) -- [R423] gamma bug, display too bright when using DVI-VGA adapter https://bugs.launchpad.net/bugs/548709 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
