Hello, In my case, appending __GL_SYNC_DISPLAY_DEVICE=DP-0 in the /etc/environment file (DP-0 is my 144hz monitor - see X Server XVideo Settings in NVIDIA X Server Settings) seems to works (config: GTX 1070/60 Hz + 144 Hz monitors).
I forced resolution + frequency in NVIDIA X Server Settings for the two monitors in the X Server Display Configuration section. Disabled Force Composition Pipeline + Force Full Composition Pipeline. Disabled Sync to VBlank + Allow Flipping (OpenGL Settings). NVIDIA driver version: 435.21 (the latest in Ubuntu 18.04.3 with HWE 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/nvidia-graphics-drivers-418/+bug/1820832/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
