Title:
System hangs after connecting or disconnecting external monitor
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Each time I connect or disconnect the external monitor my ubuntu
system will hang and a Hard reboot is necessary. Only way I manage to
have the external monitor working is to plug it before booting. Which
gets quite annoying after a while.
I had the exact same problem already with ubuntu 12.04 and was hoping
the upgrade of the system to last release 14.04 would solve it.
Although it did not. I am using a vaio vgn-sr19xn with Intel Graphics
Media Accelerator (GMA) 4500MHD. The external monitor is a Samsung Tv.
In the wiki says it is a known problem, although I was wondering weather there is some fix for this?
Which info do you need from me?
