Bug ID: 99181 Summary: RS780 blank screen on boot Product: DRI Version: XOrg git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: chithanh@gentoo.org
Hardware: BIOSTAR A780L
When booting with 3.15 or newer kernels, a monitor connected to the DVI port of the BIOSTAR A780L will stay blank. Kernel 3.14 and older work fine.
I tried forcing the output to on with video=HDMI-A-1:e but this made no difference.
