--- Comment #4 from Alex Deucher <[email protected]> --- The LVDS is detected as an 1280x800 panel. Does it seem like a backlight issue? Is this a regression? If so when did it used to work? Can you try setting radeon.backlight=0 on the kernel command line in grub to disable driver backlight control. You might be seeing a regression as a result of this patch: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4281f46ef839050d2ef60348f661eb463c21cc2e which was fixed in: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4cee6a9057d5e13911f0cb6e143d11dc1a3245dd http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ae93580ee59c02395c1711d3e6b90546b8137b86 -- You are receiving this mail because: You are the assignee for the bug.
