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-X, which is subscribed to xorg-server-hwe-16.04 in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
