Title:
[Lenovo x220] display port stopped working after move to 13.04
Status in “linux” package in Ubuntu:
Expired
Bug description:
I get a blank (turned off) display on an Eizo monitor connected via
DisplayPort to a Lenovo x220.
The display works on 12.10 and does work while booting. As soon as X
starts, the display is gone. Xrandr does show it and it can be
configured. The screenshot tool shows entire area correctly. But
nothing appears on the screen. Reconnecting the cable does the usual
flicker, as does power cycling the monitor. The display stays blank.
On 12.10 something similar occurred intermittently. After closing the
notebook lid, the monitor had to be powercycled (re-plugging the cable
did not help).
