Adding to my above report - after the update to 2:2.99.914-1~exp1ubuntu4.5~trusty1 screen started to go blank(black) constantly. In intervals from seconds to minutes. System is till running OK, I am able to start the screen by Ctrl-Alt-F1 and then Ctrl-Alt-F7. I do not know if this is really connected to driver.
