Public bug reported:
I Updated to Ubuntu 15.10 with a full new installation. My monitor (Viewpoint,
VP 712 DI, 17") that worked perfectly with 14.04 has bouts of flipping from
normal performance to pixelated nonsense images.
I uninstalled 15.10 and reinstalled 14.04 and the problem disappeared. I also
disaassembled the monitor and checked it out inside: all the capacitors are
healthy and the boards seem in perfect condition.
After being convinced that the monitor was not at fault, I upgraded
14.04 to 15.10, hoping that the driver for the monitor in 14.04 would
remain in service but apparently the upgrade (as did the new comoplete
installation) still changed the driver and my monitor is once again
acting up.
I manage, most of the time, to return my picture to normal by typing
cont+alt+del, which brings up the "shut down/restart" option. I "X" the box
closed and usually get the monitor to return to normal functioning---for a
while.
Obviously, this is not a viable solution for the long term.
My question is, how do I get and install a driver that will properly
handle the performance of my monitor? Can I "hijack" the driver from
12.04 and activate it in 15.10?
