Bug Description
My problem is, If I connect an external display (monitor, projector, etc) Ubuntu detects it only once, only the first time I plug it in. After that, I can't reconnect that external display again, Ubuntu does not see it. After a system restart the disply is detected again, for the first time I plug it in.
This problem is really annying, because initializing all the applications run before needs a lot of time.
I don't know if problem is with the libdrm package, but my syslog got a lot of these errors when I plugged OUT the display:
Jan 16 09:23:33 probook430 kernel: [ 92.060702] [drm:intel_
Jan 16 09:23:33 probook430 kernel: [ 92.066291] [drm:intel_
This problem is persistent, and can be reproduced every time with every external display.
