I've come to find out this is 100% Gnomes fault. Shortly after GTK3 was finalized they ignorantly nuked the enumeration of XScreens. Because Ubuntu/Debian is slow to update this problem went semi-undetected for years until we had to move to a system where those changes/packages had been (forced) implemented. So now anything that uses GTK is basically broken.
However there are a few workarounds. I left Ubuntu fed up with this and other things. I'm on Garuda (Arch) but because of the downgrade feature I was able to reinstall XFCE4.12 before everything was broken and hold the packages. KDE also seems to be working though it was also broken for a while. You will have to vett your applications for things that don't lock to a GPU process. So for example I use SpaceFM for file management and Sakura for a term. Sadly this will get worse as even XScreen saver is now broken as of 6.02. I reported the bug but the dev is clueless, doesn't run *nix at all. It's a grim time to have multi GPU systems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942314 Title: Crashes/bugs with dual GPUs when using Nvidia-470 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/marco/+bug/1942314/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
