Being duped here with a more specific bug, i.e 19.10 optimus hardware No login to ubuntu session possible with gdm, lightdm is ok
Maybe a few comments. This bug orig. suggests that one could actually login on optimus hardware with nvidia-drm.modeset=1 thru gdm. That was once the case, it no longer is in 19.10. The only session available is a wayland one because it falls back to Intel. As far as why users set nvidia-drm.modeset=1? I'd suggest the majority do so on optimus machines to be able to use nvidia without tearing. For the most part none have any interest in wayland even though wayland would solve tearing. Why?, because no (or virtually none) optimus machine has ever been able to use wayland & nvidia drivers. Not in the last couple of years, not now. While I don't have a desktop machine I do have a laptop with nvidia GPU only. In that case (19.04) with nvidia-drm.modeset=1 it presents and logs into a wayland session but llvmpipe only. It does work ok in a ubuntu session. Maybe I'll give it a try with 19.10 though on this machine there is no tearing so xorg is fine, currently any positives, if any, of wayland are outweighed by it's negatives. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1716857 Title: nvidia-drm.modeset=1 results in no monitors detected by Xorg To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1716857/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
