Thank you Olafur and George for your answers. I am using Gnome, so that is not the issue here.
Doing: sudo mv /usr/lib/udev/rules.d/61-gdm.rules /usr/lib/udev/rules.d/61- gdm.rules.bak Worked for me. I get gdm with options and Wayland by default. I'm back in business thanks to you. I however did follow a bunch of other instructions and now I don't if I should undo any of them. These are the things I did, in case you can provide some input: 1. echo "options nvidia-drm modeset=1" >> /etc/modprobe.d/nvidia- options.conf 2. echo 'GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX nvidia-drm.modeset=1"' > /etc/default/grub.d/nvidia-modeset.cfg 3. # systemctl enable nvidia-suspend.service # systemctl enable nvidia-hibernate.service # systemctl enable nvidia-resume.service 4. echo 'options nvidia NVreg_PreserveVideoMemoryAllocations=1' > /etc/modprobe.d/nvidia-power-management.conf 5. apt remove xserver-xorg-video-intel. (gave me an error on one boot (wifi?) but the error didn't come up in subsequent boots). And finally I did: 6. sudo mv /usr/lib/udev/rules.d/61-gdm.rules /usr/lib/udev/rules.d/61- gdm.rules.bak I can try renaming back the gdm.rules and only commenting out the gdm- runtime-config, if that is what you recommend? Should I undo any of the steps listed above for some reason? thank you,
