Title:
multi monitors - black flashes or black screen when the mouse cursor
leaves a monitor
Status in linux package in Ubuntu:
Invalid
Bug description:
I experience the following bug after updating Ubuntu 14.04. on a Dell
Latitude Laptop for Hardware Enablement Stack some days ago:
Dual Monitor Screen:
When the mouse cursor leaves one of the screens, there is either :
- no problem
- the screen becomes black just below the position of the cursor and
instantly comes back to normal.
- the screen becomes entirely black with some random colored pixels
flickering on the far left of the screen. I have to move the cursor to the
black screen, otherwise it stays black.
After the update my kernel version is 4.4.0-36-generic, and my Ubuntu
is Ubuntu 14.04.5 LTS
Thank you,
Janek Greskowiak
