Public bug reported:
I have the Dell E6510 laptop with the following Intel VGA: "Core
Processor Integrated Graphics Controller [8086:0046] (rev 02)". The
laptop sits docked in the docking station. An external 1920x1200 monitor
is connected via the docking station's DisplayPort. I have configured
the laptop's display (eDP1) to be disabled while docked, as shown in
xrandr:
$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 8192 x 8192

When the SNA is enabled and the notebook is ejected from the docking
station, the screen becomes garbled on the internal screen (please see
attachment for a screenshot). When I switch to old UXA using the
following xorg.conf:
$ cat /etc/X11/xorg.conf
Section "Device"
Identifier "Card0"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
the laptop detachment works flawlessly and the screen is not garbled.
