[Bug 1820832] Re: [xorg] multiple monitors: limits the framerate of faster 120/144hz monitors to 60hz
dreamcat4, Ubuntu 19.10 is not supported. It reached end of life on July 17, 2020. This is a bug/design feature of Xorg graphics drivers like Nvidia and AMD's. You can work around it either by explicitly configuring the driver to sync to the fastest monitor, or by enabling "TearFree" if available. For a more long term permanent solution, using GNOME Wayland sessions should never hit such a problem. But that also requires your graphics driver support Wayland sessions :( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820832 Title: [xorg] multiple monitors: limits the framerate of faster 120/144hz monitors to 60hz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1820832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1820832] Re: [xorg] multiple monitors: limits the framerate of faster 120/144hz monitors to 60hz
OK I have now regression tested on the latest 19.10, with the above ^^software stack. All except incrementing the kernel from 5.8.11 to 5.8.13. I can now confirm that the old bug has also re-appeared on 19.10 too. So it is not only exclusive to 20.04. To myself, I really don know what to try. But I had been holding off upgrading to 20.04 only because of this bug. Daniel - do you need me for any more testing on 19.10? So i may be free to upgrade? Thank you for letting me know. My opinion would be first try rolling back the nvidia driver stack, to a version that was latest at the time when we last confirmed this bug was fixed. I.e. nvidia-driver-450/eoan,now 450.57-0ubuntu0~0.19.10.2 amd64 [installed] NVIDIA driver metapackage Roll that back. Hopefully we can do this still on 20.04? Is that older package going to still work on 20.04? Thanks again!

It would be nice to understand what is going on here. Currently on 19.10 and have not upgraded to 20.04 yet... because of this very same bug! It took so long to get rid of the last time around. Many months. Should also do a regression test here back on 19.10 too? It seems I can install both the latest kernel v5.8.11 and the nvidia drivers are currently at 450.57 (on this system).

[Bug 1820832] Re: [xorg] multiple monitors: limits the framerate of faster 120/144hz monitors to 60hz
Hello there. Good news for a change: Re-tested this bug today on latest linux 5.3.1 kernel and nvidia 435.21 binary (closed) drivers. And it seems like there might be some improvement now. What I noticed this time: * Enabled 120hz overclock on my high refresh 120hz monitor, and rebooted this monitor. It is my primary display. * Opened nvidia settings ("NVIDIA X Server Settings") * Set the frame rate of this dispaly in there to 120hz with force full composition pipeline both on * Frame rate was initially capped at 60 fps. Which matches the slower 2nd monitor as before. As shown by the command: 'sudo journalctl -f' * Then I unplugged my 2nd slower 60hz monitor. * Frame rate was still capped at 60 fps * Closed some graphical (probably open GL based) programs: Glxgears, kodi, and bitwig studio. * Frame rate was now capped to 71 fps * Went back to NVIDIA settings GUI * Navigated to "OpenGL Settings" page * Un-checked all of the first 4 settings on that page, which were: [ ] "Sync to VBlank" [ ] "Allow Flipping" [ ] "Allow G-SYNC/G-SYNC Compatible" [ ] "Enable G-SYNC/G-SYNC Compatible Visual Indicator" * The fps shown in 'sudo journalctl -f' is now going all the way up to 120hz. Whilst running the command 'glxgears' to make a graphical workload I then went back and re-enabled all of the options in the OpenGL page, except for "Allow Flipping", like this: [x] "Sync to VBlank" [ ] "Allow Flipping" [x] "Allow G-SYNC/G-SYNC Compatible" [x] "Enable G-SYNC/G-SYNC Compatible Visual Indicator" * The frame rate was still reaching up to 120Hz. * Then I plugged my 2nd slower 60hz monitor back into the NVIDIA graphics card * Previously this was the point in the test when the frame rate would immediately drop back down to only 60 FPS However this time, it stayed at 120fps. Which is very encouraging and a positive result from my testing today. What I am not sure about: * How easily it is to get the system into this state * For example whether it can come up like this after a reboot. Or if it requires a certain ritual / ceremony / fernagaling to get everything to this point * How stable this state is, how delicate / easily broken by launching some specific program(s). In particular I am thinking about fullscreen games. However my gpu here (GT 1030) simply isn't powerful enough to do proper testing for more demanding programs and workloads like that. Anyhow I think it's a great result from what we can observe so far. Just wish I had a better graphics card now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820832 Title: [xorg] multiple monitors: limits the framerate of faster 120/144hz monitors to 60hz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-418/+bug/1820832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

well by that logic, then somebody with an amd ryzen APU (such as 3200G or whichever with the integrated Vega graphics). Would also not be affected by this bug. But the other reason would be that intel's linux igp drivers are not affected.

I can confirm this bug too. But additionally I have noticed one more interesting fact: It seems that this bug affects only PCs with dedicated GPUs (AMD, Nvidia). When I connect monitors into motherboard ports this bugs disappears. In my case via VGA(60Hz) and DVI-D(120Hz), but I believe that with HDMI and DisplayPort there will be the same results as with VGA or DVI. Unfortunately I haven't got a motherboard with DP or HDMI to test it. Because of this behaviour I have a theory that the bug exists only in Nvidia/AMD drivers for dedicated GPUs.

I can also confirm that this bug is still present. I'm on Ubuntu 19.04 with the latest drivers & updates installed. Also, I want to add something here: It's not that it specifically limits the framerate to 60 Hz. Rather, it limits it to the monitor with the lowest refresh rate. Try setting one monitor's refresh rate to 30 Hz, and you should instantly notice how laggy the whole desktop environment becomes. I understand that this issue might be looked at as "not that important", but I believe a lot of people that would love to switch from Windows to something like Ubuntu really wouldn't appreciate the fact that their 144 Hz monitor doesn't work as intended.

I have instead logged it against version 418, assuming the problem is still there. ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New ** Changed in: mutter (Ubuntu) Status: New => Invalid ** Tags added: multimonitor -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820832 Title: (xorg) multiple monitors: limits the framerate of faster 120/144hz monitors to 60hz To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1820832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This is a bug/limitation of the graphics driver itself. So I will reassign this bug to NVIDIA. Also Mitchell, please let us know which AMD Xorg graphics driver you are using (attach a Xorg.log?). As luck would have it, one user upstream found a solution for NVIDIA documented here: https://gitlab.gnome.org/GNOME/mutter/issues/503#note_463305 ** Bug watch added: gitlab.gnome.org/GNOME/mutter/issues #503 https://gitlab.gnome.org/GNOME/mutter/issues/503 ** Also affects: mutter via https://gitlab.gnome.org/GNOME/mutter/issues/503 Importance: Unknown Status: Unknown ** Package changed: gnome-shell (Ubuntu) => nvidia-graphics-drivers-418 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820832 Title: (xorg) multiple monitors: limits the framerate of faster 120/144hz monitors to 60hz To manage notifications about this bug go to: https://bugs.launchpad.net/mutter/+bug/1820832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Just confirming that this issue affects me also. Here's my post from the other other bug: I'm using Xorg with an AMD Vega 64. Both displays are connected to the GPU. My main 144hz display is connected via Display Port, and my second 60hz display is connected via HDMI. I'm using Mesa 19.1.0-devel - padoka PPA When I perform the test case in the first post, I get high framerates when the secondary display is disabled, and only 60 fps when it's enabled. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1820832 Title: (xorg) multiple monitors: limits the framerate of faster 120/144hz monitors to 60hz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1820832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
