Proposed fix fixed it for me (Lenovo 3000 N200). Many thanks.
Original error was:
compiz[1519]: segfault at 0 ip 00007f54d91a2986 sp 00007ffd58273a20
error 4 in i965_dri.so[7f54d8bca000+82d000]

[regression] compiz crashes after Mesa upgrade

Bug description:
[Impact]
When I use the Unity session I automatically get logged out under these
conditions:
When I hover with my mouse over any icon of the sidebar.
When I press the alt key.
When I press the super key.
running dmesg after this unwanted logout happens I get following
information:
compiz[10616]: segfault at 0 ip 00007fbca309feeb sp 00007fff5f59a4d0
error 4 in i965_dri.so[7fbca2af6000+7e4000]
This is caused by a mesa upgrade, which added a patch for bug #1727401. The
crasher is reproduced on:
- gen4 / gen5 Intel
- if using modesetting X driver, like when xserver-xorg-video-intel is not
installed, or the HWE stack is installed (xserver-xorg-core-hwe-16.04 defaults
to modesetting)
[Test case]
Log in to Unity, open the dash or try to log out etc. Compiz shouldn't crash.
[Regression potential]
The backported patches need to be tested, here for regressions and on 1727401
that they fix the original bug (again).
Best to test on a wide array of Intel HW:
gen4 (965GM/GM45/G45)
gen5 (Ironlake)
gen6 (Sandy Bridge)
gen7 (Bay Trail, Ivy Bridge, Haswell)
gen8 (Braswell, Broadwell)
gen9 (Apollo Lake, Skylake, Gemini Lake, Kaby Lake, Coffee Lake)
