I found a workaround. If I create a file `/etc/X11/xorg.conf` with the following contents: % cat /etc/X11/xorg.conf # Workaround for Debian bug#1005359. Section "Device" Identifier "modesetting" Driver "modesetting" Option "UseGammaLUT" "false" EndSection % then the Xorg server comes up fine. As the comment indicate, I took this workaround from bug#1005359, so maybe the two bugs should be merged. (I hadn't tried this earlier since I presumed that the hardware was sufficiently different between my X201s and my Librem mini that the bugs would also be different). Stefan
