Yes, I still observed it under current HWE server 1.19 with modesetting driver. (I intentionally switched back from Intel to modesetting to test it). I did not see it recently though (without any X related updates), but what I see currently is - screen goes blank, I move mouse, screen unblanks and then after second or so quickly blanks/unblanks again. It looks as if some hardware re-probing happens.
It is possible that it is kernel related, there were some i915 fixes in kernel updates. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1665850 Title: Screen corruption after unblank with HWE stack To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server-hwe-16.04/+bug/1665850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
