By the way, over the last week, I also (automatically) sent several apport-gpu error reports. However, I do not know how I can refer to these here, because the system does not give me any error handling number or the like.

Often hard boot necessary Status in “xorg” package in Ubuntu: New Bug description: For about two weeks (I assume one of the driver updates caused the problem), the Intel GPU X driver crashes several times during a session. Several times a day, a hard reboot is necessary since everything but the mouse cursor freezes. It is also not possible to switch to text consoles via Alt-F keys. It is a particularly severe bug, because it results in system freezes and therefore in data loss. It happens in Gnome 3 Shell and also in Unity. I also cannot associate the Intel GPU driver crash with any particular activity. Sometimes it even crashes without having done anything. I hope the attached log files will help to find the problem and to fix it. If you need more information, I am more than willing to provide additonal tests.
