Priority: medium Bug ID: 78987 Assignee: dri-devel@lists.freedesktop.org Summary: black screen when trying to enable external VGA screen on Trinity APU laptop Severity: major Classification: Unclassified OS: All Reporter: dev@lynxeye.de Hardware: Other Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
Created attachment 99447 --> https://bugs.freedesktop.org/attachment.cgi?id=99447&action=edit dmesg from failing machine
Plugging in an VGA monitor and trying to enable it results in black screen on both the internal laptop display as well as the external VGA monitor.
The graphics is dead after this, I have not found any way to restore the screen. However the machine is still responding to ssh and I was able to pick up an quite interesting dmesg snapshot.
If you need me to test patches or need any other information, just ping me.
