[Desktop-packages] [Bug 1877226] Re: nvidia - external display unavailable after screen goes to sleep
Daniel et al, I wanted to provide an update based on the latest official mutter release as of today - 25.Mai. The issue still exists. However, I provide the following in the event it helps to refine the underlying issue. Please let me know if there are logs that would be helpful to you or additional steps you would like me to take to help with the diagnosis. >From the desktop with dual monitors running: 1) Goto lock screen (win+l) 2) initial screen shows both monitors active 3) both screens go blac 4) external monitor goes into standby mode due to loss of signal 5) primary laptop displays turns on momentarily and a resolution change is observed based on the size of the mouse. 6) primary display goes black. 7) logging back in and going to display settings 8) system no longer uses external display and returns to single display 9) open gnome-control-center -> displays. Single Display is active 10) Attempt to select join displays 11) Error at the top of gnome-control-center: Changes cannot be applied - This could be due to hardware limitations 12) select mirror - click apply 13) a keep settings dialogue will pop-up briefly before the screen goes blank. When the screen comes back on, both screens come back on, with a new keep settings dialogue. 14) select keep settings. gnome-control-center now shows Joing Displays as being active. not/not mirror. - As an additional note. If instead of going to the lock screen I suspend the system, which includes both monitors going into sleep mode, the above issue is not observed. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1877226 Title: nvidia - external display unavailable after screen goes to sleep Status in gnome-control-center package in Ubuntu: New Status in mutter package in Ubuntu: New Status in nvidia-graphics-drivers-440 package in Ubuntu: New Bug description: On ubuntu 20.04 (Linux 5.4.0-29-generic #33-Ubuntu SMP Wed Apr 29 14:32:27 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux) with nvidia proprietary driver 440.64 with an nvidia MX250 (Lenovo T590): 1) Attach monitor via HDMI 2) Monitor is properly detected.

[Desktop-packages] [Bug 1877226] Re: nvidia - external display unavailable after screen goes to sleep
I have seen the error in step 10 before. In my case it was caused by bug 1874207 in mutter so maybe wait for that to be fixed... Also, next time the external display is "unavailable" please open a Terminal window and run 'xrandr'. Can you still see the external display there? ** Tags added: nvidia ** Tags added: multimonitor ** Changed in: gnome-control-center (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1877226 Title: nvidia - external display unavailable after screen goes to sleep Status in gnome-control-center package in Ubuntu: Incomplete Bug description: On ubuntu 20.04 (Linux 5.4.0-29-generic #33-Ubuntu SMP Wed Apr 29 14:32:27 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux) with nvidia proprietary driver 440.64 with an nvidia MX250 (Lenovo T590): 1) Attach monitor via HDMI 2) Monitor is properly detected.
