dmesg output
After booting with KMS enabled my laptop screen turns black as soon as X
starts, while my external screen continues to work. The desktop still expands
to both screens. If I disconnect the external monitor everything runs smooth, I
can even connect the monitor afterwars and enable it through xrandr. But the
laptop screen turns black again when I run glxgears through Gallium. I can turn
the black screen off and on through xrandr, but it stays black.
With KMS disabled everything works fine. I rebuild my graphic stack from git
but the problem remained. The error first occured months ago, so I disabled
KMS. Today I tried it again and the error is still there.
