--- Comment #2 from Stefan Hoffmeister <stefan.hoffmeis...@econos.de> --- Based on comments in https://bbs.archlinux.org/viewtopic.php?id=250684 I looked at there being a chance of racing between drm and systemd-logind (which apparently is responsible for handing out the file handle to card0). In the two blocks below based on `journalctl -b<the boot> | grep -E '\[drm\]|systemd-login'`, I do not see much of a difference in ordering, and none that would seem to matter (not that I would be competent in assessing that): ``` +++ broken fedora kernel: i915 0000:00:02.0: [drm] VT-d active for gfx access fedora kernel: i915 0000:00:02.0: [drm] Using Transparent Hugepages fedora kernel: i915 0000:00:02.0: [drm] Finished loading DMC firmware i915/tgl_dmc_ver2_12.bin (v2.12) fedora kernel: i915 0000:00:02.0: [drm] GT0: GuC firmware i915/tgl_guc_70.1.1.bin version 70.1.1 fedora kernel: i915 0000:00:02.0: [drm] GT0: HuC firmware i915/tgl_huc_7.9.3.bin version 7.9.3 fedora kernel: i915 0000:00:02.0: [drm] GT0: HuC: authenticated for all workloads fedora kernel: i915 0000:00:02.0: [drm] GT0: GUC: submission enabled fedora kernel: i915 0000:00:02.0: [drm] GT0: GUC: SLPC enabled fedora kernel: i915 0000:00:02.0: [drm] GT0: GUC: RC enabled fedora kernel: i915 0000:00:02.0: [drm] Protected Xe Path (PXP) protected content support initialized fedora kernel: [drm] Initialized i915 1.6.0 20201103 for 0000:00:02.0 on minor 0 fedora kernel: i915 0000:00:02.0: [drm] fb0: i915drmfb frame buffer device fedora kernel: i915 0000:00:02.0: [drm] Selective fetch area calculation failed in pipe A fedora systemd[1]: Starting systemd-logind.service - User Login Management... fedora systemd-logind[1520]: New seat seat0. fedora systemd-logind[1520]: Watching system buttons on /dev/input/event1 (Power Button) fedora systemd-logind[1520]: Watching system buttons on /dev/input/event0 (Lid Switch) fedora systemd-logind[1520]: Watching system buttons on /dev/input/event2 (Sleep Button) fedora systemd-logind[1520]: Watching system buttons on /dev/input/event15 (Intel HID events) fedora systemd-logind[1520]: Watching system buttons on /dev/input/event16 (Intel HID 5 button array) fedora systemd-logind[1520]: Watching system buttons on /dev/input/event3 (AT Translated Set 2 keyboard) fedora audit[1]: SERVICE_START pid=1 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0 msg='unit=systemd-logind comm="systemd" exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=success' fedora systemd[1]: Started systemd-logind.service - User Login Management. fedora kernel: [drm] [nvidia-drm] [GPU ID 0x00000100] Loading driver dell.home systemd-logind[1520]: Watching system buttons on /dev/input/event8 (Cherry GmbH CHERRY Corded Device) dell.home kernel: [drm] Initialized nvidia-drm 0.0.0 20160202 for 0000:01:00.0 on minor 1 dell.home kernel: nvidia 0000:01:00.0: [drm] Cannot find any crtc or sizes dell.home systemd-logind[1520]: Watching system buttons on /dev/input/event10 (Generic USB Audio Consumer Control) dell.home kernel: nvidia 0000:01:00.0: [drm] fb1: nvidia-drmdrmfb frame buffer device dell.home systemd-logind[1520]: New session c1 of user sddm. dell.home systemd-logind[1520]: Session c1 logged out.
