I just installed kernel 4.4.0-23.41 from xenial-proposed and it seems to include whatever alleviated this issue. My laptop isn't crashing anymore.
There is the occasional glitch: sometimes when I enter my password at the login screen, the screen will actually not redraw at stay at the login screen while the contents seem to have changed. Moving my mouse cursor actually changes the cursor depending on what should be underneath. Switching to anther VT and back to X.org redraws the screen and fixes it. Also the title bar sometimes gets garbled. Moving or resizing the window fixes that. I did h experience these issues with 4.6 too, by the way. All in all, it's definitely usable this way! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1569383 Title: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1569383/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
