[Bug 1665850] Re: Screen corruption after unblank with HWE stack
I tried to install mesa 17.2.4 (which should include this commit) from ppa ubuntu-x-swat, but still the same - as soon as I attempt to enable DRI3 I get screen corruption and tearing. -- 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
[Bug 1665850] Re: Screen corruption after unblank with HWE stack
Update: recently one of programs I use started to complain that screen was not DRI3 capable. I am using Intel driver which apparently defaults to DRI2. I forced it to DRI3 using Option "DRI" "3" After that I immediately got tearing during video and the same strange corruption of screen (fast blinking). As modesetting driver defaults to DRI3 it appears the issue is not Intel vs. modeseting but rather DRI2 vs. DRI3. Googling around suggests that this may be this upstream bug: https://bugs.freedesktop.org/show_bug.cgi?id=97957 If there is Ubuntu package for 16.04 that includes above commit I would be more than happy to test it. ** Bug watch added: freedesktop.org Bugzilla #97957 https://bugs.freedesktop.org/show_bug.cgi?id=97957 -- 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

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

After I observed visible tearing when watching video on external HDMI screen I switched back to Intel driver.

I noticed that Xorg is now using modesetting driver while in the past I think it was using Intel driver.
