Screen resolution going back to default (Ubuntu Budgie 20.10, NVIDIA, Intel i7)

Budgie Desktop
1

Hi everyone

I am using a fresh out of the box Budgie 20.10 install on my primary desktop.

  • i7 2600k
  • 16GB DDR
  • GTX 1070

After install, my full screen resolution was correctly detected, looked amazing (1440p). After a reboot though, things shift back to 1024x768 and I can’t select a different resolution from the GUI. The NVIDIA driver appears to be loaded.
nvidia-smi shows

This is the second attempt at this, first time I used a more maximal approach when install budgie (all the apps out of the box), same issue as with this more minimal one.

Any help much appreciated.

Sounds like a bug in the proprietary driver :frowning:

Does any of this help you? https://askubuntu.com/a/222281/14356

Thansks - I followed Jim Salter’s approach (saving nvidia settings to /etc/X11/xorg.conf) and that seems to have made no difference.

My xorg.conf now has

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "Stereo" "0"
    Option         "nvidiaXineramaInfoOrder" "DFP-2"
    Option         "metamodes" "2560x1440_144 +0+0"
    Option         "SLI" "Off"
    Option         "MultiGPU" "Off"
    Option         "BaseMosaic" "off"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

in it, which matches the answer given in that link - but I still get bogus resolution following a reboot.

It turns out I can kick this into life by running sudo systemctl restart display-manager - not ideal, but it’s nice to have 1440p again :smiley:

Please file a bug report so that the Canonical devs are aware

ubuntu-bug libmutter-7

OK thanks I will try and do that.

james@beasty:~$ ubuntu-bug libmutter-7
dpkg-query: no packages found matching libmutter-7

ah - typo - libmutter-7-0

OK I submitted a bug, but unfortunately that PC had to go into a shipping container tomorrow morning, so I’m out of troubleshooting time for the next 12 weeks. :smiley:
