Just seen several times: When I open a dialog window in LibreOffice Calc (for example, in order to save a table as .csv or after right-click and then choosing "Format Cells"), the window flickers and then Ubuntu crashes, going back to "Scanning for btrfs file system", and then the Ubuntu login appears.

Here is the dmesg output:

[39325.939024] [drm] stuck on render ring
[39325.940137] [drm] GPU HANG: ecode 7:0:0x87d77c3e, in Xorg [21731], reason: Ring hung, action: reset

[39333.943197] drm/i915: Resetting chip after gpu hang

It's curious that this error only occurs with LibreOffice, and only after upgrading from 15.10 to 16.04 LTS.

Edit 2: No crashes lately, but the display is still weird.

Edit 3: I installed xserver-xorg-video-intel and later mesa-utils, and both do not change the appearance of LibreOffice.

  • What are your machine specs? Apr 24, 2016 at 19:11
  • Just added them. Are some useful specs missing?

  • Thank for mentioning xserver-xorg-video-intel. It fixed in my case.

I just did a clean re-install of 16.04, and the problem doesn't occur anymore. I battled with Libreoffice when it ran on 16.04, upgraded from 15.10 by do-release-upgrade -d.

It seems the upgrade wasn't that clean...

Whether it's Impaled Impala 8.10 or another release, IMHO one should rather do a backup of all important directories and then a clean re-install instead of upgrading Ubuntu.
