For the help of other users, I just want to mention that in Ubuntu 17.04, I ended up switching back to stable xorg and *removing* xserver- xorg-video-intel, as suggested in some online documentation, in order to force the modesetting driver to run. I'd see modesetting and glamoregl modules loading in the Xorg.0.log file.
Then, I disabled hardware acceleration in Chrome, using the official setting available in Chrome settings. (Not via a flag.) Search for "acceleration" in chrome://settings and then un-check that option. With these two corrective actions, I seem to have a stable machine, even when running Chrome day-in day-out for a long time in gnome-shell. I also can't force a crash with Facebook 3D images any longer. This is probably the right set of recommendations for users with my Lenovo X1C model or similar Skylake & GPU hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1710051 Title: xorg crash/freeze when Chrome uses WebGL, caused by: GPU HANG: ... chrome ... reason: Hang on render ring, action: reset To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1710051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
