y2log archive after X11 hang

## observation

On an openSUSE Leap 42.3 Build 0243 upgraded from openSUSE Leap 42.2 in a
plasma session after starting kontact for the first time I encountered a hang
of the X11 session. The plasma session was not responsive at all anymore. The
text login was still working. Logs provided.

dmesg output:

## further details

I assume the problem is linked to the graphics driver. The hardware is

```
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (primary) (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated
Graphics Controller (secondary) (rev 0c)
00:03.0 Communication controller: Intel Corporation Mobile PM965/GM965 MEI
Controller (rev 0c)
```
