2021-10-28 15:12:31 jeremyszu description We are facing an issue that GDM starts with Wayland instead of Xorg, despite of 61-gdm.rules' gdm-disable-wayland for NVIDIA graphics. The issue happens because gdm-disable-wayland is executed after GDM has started. The reason why the udev rules takes so long is because the the runtime suspended NVIDIA GFX takes more than 1 second to runtime resume, hence the driver starts the probing routine rather late. The proper solution is to impose a barrier like systemd-udev-settle.service before GDM, but limits to the GFX device only to avoid waiting for all udev rules are finished. Since such mechanism isn't available right now, workaround the issue by enabling runtime PM after driver is bound to avoid the runtime resume delay, and hope GDM always starts after the probing is done. Please backport below patch to supported nvidia-drivers: https://github.com/tseliot/nvidia-graphics-drivers/pull/41/commits/7e9e4d4a827dc9da0e27058871034245ae4b7508 [Impact] * In some race condition, the GDM starts before gdm-udev rule be applied. * That's because somehow the nvidia driver takes more times to do the runtime resume. Thus, apply the workaround to postpone to enable RTD3. [Test Plan] 1. In problematic machine, warn/cold boot the system. 2.1 System hangs on GDM login shell 2.2 After apply this patch, the system can enter the login screen. [Where problems could occur] * Postpone to enable RTD3 when binding driver should not impact the functionality since the power consumption usually not be consider in booting stage. --- We are facing an issue that GDM starts with Wayland instead of Xorg, despite of 61-gdm.rules' gdm-disable-wayland for NVIDIA graphics.
