I suffer also from: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/954426 Trying to switch to console mode then come back doesn't trigger these lines. This report is only about this BUG behing logged into Xorg file. But it might be of interest of noting that I'm chasing an sudden issue with my typecover : the trackpad stopped working. For now, this is probably unrelated.
