[Ubuntu-x-swat] [Bug 1547077] Re: Some glyphs drawn consistently wrong, bug comes and go
The bug is still triggered (not always) by suspend-to-ram then wake-up. This make a frustrating user experience since the most affordable workaround is to close the session the reopen it when bug occurs. Since many applications are defaced (see screenshots), the user cannot properly check if their work is saved.

[Ubuntu-x-swat] [Bug 1547077] Re: Some glyphs drawn consistently wrong, bug comes and go
Unfortunately, the bug occurred again a few minutes ago. This means that uninstalling light-locker and using xscreensaver instead is not enough to prevent the bug from occurring. AFAIK, doing so avoids light-locker creating possibly short-lived X servers (for the purpose of asking password for unlocking screen while allowing to open a new session). Thus I believe that the bug is not triggered by running several X servers. Still, I've noticed that the bug is not active for the whole machine at a time, but can be active on an X server (for example, while typing password to unlock) and inactive on another (main session) or vice versa. All in all, this and bug https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1558236 make (for our usage pattern at least) two important regressions that 16.04 introduces.

Hello Christopher @penalvch. > Could you please report this problem through the appropriate channel by following the instructions verbatim at http://nouveau.freedesktop.org/wiki/Bugs/ ? I performed part of it. The situation passed the "TroubleShooting" step. I checked on the bugzilla, visited #nouveau to see if the issue was known. Found nothing really close. I'll try to invest more time. In the meantime I used 15.04 and 15.10 (that I kept on separate partitions on same machine) and observed that there I had uninstalled light-locker and replaced it with xscreensaver to work around a freeze- with-black-screen-on-wakeup issue. Those used nouveau 1.0.11. So, I went back to 16.04 (which uses nouveau 1.0.12), uninstalled light- locker and replaced it with xscreensaver. If there is no more activity on this bug report for a long time, then it probably means that it is an effective workaround. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1547077 Title: Some glyphs drawn consistently wrong, bug comes and go To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1547077/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

After another failed attempt at installing nVidia driver through software-properties-gtk here is another bug report https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-361/+bug/1556960 So bugs happens every few days. Hypothesis: bug happens when another X server is run. This happens with needing to unlock session, either after plain lock or after resume from syspens. That might be why it did not happen on older Xubuntu where I used xscreensaver instead of light-locker. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1547077 Title: Some glyphs drawn consistently wrong, bug comes and go To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1547077/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Still occurs with latest build xserver-xorg-video-nouveau 1:1.0.12-1build2 *Bug is severely impacting for daily work.* Strangely enough, video worked rather well with 14.10 and 15.04, we mainly had trouble with NetworkManager there.

[Ubuntu-x-swat] [Bug 1547077] Re: Some glyphs drawn consistently wrong, bug comes and go
Hello. Suspending then resuming system seems to have some effect. This morning, after resume from suspend (with session still open), all text glyphs appeared blank on the lightdm screen. I expected the session to be fully unusable, but surprisingly, the session itself has had no problem at all since unlocking it (one hour ago). Contrary to first times the bug appeared, I'm not currently using an external screen (and have rebooted since the last time an external screen was used), so the bug does not need that to appear. I would consider the bug severe since it make the whole desktop look awfully broken. :-) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1547077 Title: Some glyphs drawn consistently wrong, bug comes and go To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1547077/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
