I'm adding a task for gdm to this bug. The reason is that if simpledrm is used, we've found race conditions that occur where the transition from simpledrm to the proper KMS driver may race with gdm starting up the login screen.
When gdm loses the race you end up with a black screen. So please make sure that any kernels that do adopt simpledrm the matching GDM for OS releases that run this kernel (think about HWE!) will need to pick up this GDM fix as well. https://gitlab.gnome.org/GNOME/gdm/-/commit/04e119c8332a564cfad05dfb9cb6ec547d5ba954 ** Also affects: gdm (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in Ubuntu. https://bugs.launchpad.net/bugs/1965303 Title: Migrate from fbdev drivers to simpledrm and DRM fbdev emulation layer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm/+bug/1965303/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
