I can confirm this on a fresh install of Lubuntu 16.04 on a relatively new laptop. This bug effectively renders the laptop useless.
Libreoffice crashes X regularly (!) and hence is not usable. When I look at /var/log/syslog the culprit is always something like: May 9 20:55:54 kermit kernel: [ 46.807723] [drm] GPU HANG: ecode 7:0:0x85fffdfc, in Xorg [812], reason: Ring hung, action: reset May 9 20:55:54 kermit kernel: [ 46.809807] drm/i915: Resetting chip after gpu hang This seems to be a well known problem with the i915 driver. I've tried some of the fixes that people suggest (adding various i915 options to grub like i915.enable_rc6=0 i915.semaphores=0 i915.modeset=1 i915.use_mmio_flip=1 i915.enable_ppgtt=1). But so fare nothing works. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575301 Title: GPU Hang [i915 / drm] crashes whole session; triggered by LibreOffice dialog boxes (regression) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1575301/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
