Hm, rotate appears to do nothing with master bits from today. Will investigate. impacting moblin the issue also happens on 855gm and 915gm Looks like the rotation actually happens correctly, but the server disables the output. Doing a "xset dpms force on" turns the display back on and things seem to work. Looks like the server's DisableUnusedFunctions is turning off the LVDS after the rotation happens, which means the output's crtc isn't set correctly. Created attachment 24005 [details] [review] re-enable disabled outputs at mode set time With the mode_set_major hook we may need to re-enable a previously disabled output at rotate time. I'm not sure this is the correct fix, but please try it out (works for me).
