[Bug 1808626] Re: Triple buffer flickering and weird display updating
Any other workarounds? For me adding video=VGA-1:e helped only for limited time: after the computer got into sleep mode and woke up again, the flickering problem was back. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808626 Title: Triple buffer flickering and weird display updating To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1808626/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I didn't think that Ubuntu's SimpleScreenRecorder would record the corruption but it records it just fine: Here's an HD video of the screen corruption: https://www.youtube.com/watch?v=6dG_awbM5oo -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808626 Title: Triple buffer flickering and weird display updating To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1808626/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1808626] Re: Triple buffer flickering and weird display updating
Been fiddling with rotating and unrotating displays and when it starts drawing improperly when rotated, I can unrotate the displays and the improper drawing/flickering disappears. Also the improper drawing disappears when I go to mirror mode. I would imagine most people don't see this bug because few people have one monitor rotated left and have a second monitor in normal orientation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808626 Title: Triple buffer flickering and weird display updating To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1808626/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1808626] Re: Triple buffer flickering and weird display updating
I've been hesitant to try to reproduce this because my system runs so well for a long time when this doesn't crop up. So I rebooted without the video=VGA-1:e parameter and it starts doing this sort of thing immediately. I uploaded a video at youtube: https://www.youtube.com/watch?v=2JOy_ilLAlw Strangely, when I add the video=VGA-1:e parameter it comes up fine and I tried to rotate and unrotate my monitors and various manipulations with ubuntu's display settings and xrandr and I couldn't get it to do the flickering thing. And I think I misspoke, it doesn't seem like triple buffering flicker but perhaps double buffering flicker. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808626 Title: Triple buffer flickering and weird display updating To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1808626/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1808626] Re: Triple buffer flickering and weird display updating
I've been running the same setup and it runs absolutely perfectly if I boot up with editing the Ubuntu command line in grub and add video=VGA-1:e BOOT_IMAGE=/boot/vmlinuz-4.15.0-43-generic root=UUID= ro drm_kms_helper.edid_firmware=VGA-1:edid/hannsg.bin video=VGA-1:e adding the video=VGA-1:e will allow the drm_kms_helper.edid_firmware parameter to work and I get my proper display. If I don't add the video=VGA-1:e line it will come up at 1024x768 mode and give a "Could not apply the stored configuration for monitors". After I do this following xrandr command and the stored configuration is restored I get the flickering problem virtually INSTANTLY. $ xrandr --newmode "1920x1080R" 138.50 1920 1968 2000 2080 1080 1083 1088 +hsync -vsync; xrandr --addmode VGA-1 "1920x1080R" With the video=VGA-1:e the stored configuration comes up properly on initial boot and the video drivers work perfectly, no flickering. https://ptouchman.blogspot.com/2018/12/my-edid-was-going-unrecognized- until-i.html I'll post a video when I dig out my digital camera. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808626 Title: Triple buffer flickering and weird display updating To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1808626/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
