Just tested, installed and worked fine nVidia 3060 Ti

Will test sway again soon as this particular gfx card has never worked with sway on proprietary drivers, but works fine for nouveau drivers

Add, if not already, into your environment or bashrc.

I add these into my NixOS, fedora and now, solus and it does help

    But you should keep the current one right? Windows in mind, I deinstalled my drivers first, did a reboot and installed the beta drivers afterwards. But my system get stucked at the bios menu. So I had to use the solus history command to jump back in time and let my pc boot again. Had no time to test it again, maybe later this day.

      Phiqu But you should keep the current one right?

      Do you mean whether one should keep the other driver version installed? No, that's not possible.

      How did you install the driver?

          Staudey
          Via SoftwareCenter, which seems not the way to go. So I installed the beta drivers now via terminal and had no problems.

              Phiqu Well, it should work just as well from the Software Center as long as you choose the correct packages.

                ibm450 thanks for the tip, I did add them to my bashrc, unfortunately didn't work, when loging in to a sway session the screen goes black, then after a second or two returns back to the login. it seems Wayland stuff just doesn't like proprietary drivers for this particular card(3060 Ti). but thanks for the export variable, I will definitely keep them handy for future use
