Bug#755116: [xorg] impossible execute startx

[Vincent Cheng]

reassign 755116 nvidia-graphics-drivers
forcemerge 755138 755116
thanks

Merging duplicate bugs (and thus closing). The root issue is that
nvidia-graphics-drivers wasn't updated in time for the xserver 1.16
transition and ABI bump, and was thus temporarily unavailable /
non-installable. Fixed in nvidia-graphics-drivers/340.24-1.

Regards,
Vincent
