Without any deeper analyses I created a patch which simply reverts them. With this patch today drm-nightly (commit 874703062650d24d701aa79e6ab25bc14ace0475, 4.9.0) works on ASUS T100HA with this trick: DISPLAY=:0 xrandr --output DSI-1 --off sleep 1 DISPLAY=:0 xrandr --output DSI-1 --auto Maybe even without, I have to do more tests. I have Xorg running with kms and I can control brightness.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
