3D acceleration/DRI on the local LCD screen is fine, works.
Mesa DRI R600(TURKS 6740) TCL DRI2.
When booting with external Samsung 22" LCD monitor works fine while in fb mode, when the module radeon modeset=1 loads, the local LCD is still fine, the Samsung is flashing but readable.

At startx, the Samsung goes blank.

Comment 1 Alex Deucher 2012-04-25 06:23:14 UTC 
Is this still an issue with a newer driver/kernel?  Is this a hybrid laptop?  Please attach your xorg log and dmesg output.
Comment 2 Adam Jackson 2018-06-12 19:06:03 UTC 
Mass closure: This bug has been untouched for more than six years, and is not
obviously still valid. Please reopen this bug or file a new report if you continue to experience issues with current releases.
