Public bug reported:
The first time a secondary display/projector is connected to my laptop,
it is detected and works in mirrored mode. However, once I open System
Settings > Displays, the seconday display gets disabled. Loging out and
rebooting doesn't solve the problem. At least not right away. A few
reboots later secondary display starts working again. Occasioally I'm
able to use Fn+F4 to switch between different modes (mirrored,
extended), but it usually doesn't last long. As soon as System Settings
is activated, the secondary display is disable and no longer detected.
Additional clues:
1) If I leave a display plugged in and reboot, it is activated on login screen,
but shuts off as soon as I login. Pressing 'Detect Displays' button is Displays
settings does not bring it back.
2)
Every time I open System Settings (even without external displayed plugged in)
there is a short lag and even the moust stops moving for about a second. The
following shows up in the log:
