Note that if nvidia_drm is starting so late then plymouth won't display in that case. Because Plymouth prioritises DRM and won't fall back to any other options (hence won't display anything!) unless boot takes longer than 8 seconds.

Hi Seb, FWIK, the fix from gdm is not mandatory. The display-manager (inside u-d-c) will handle it. but if any flavor which doesn't use u-d-c then gdm upstream also provide this commit https://gitlab.gnome.org/GNOME/gdm/-/commit/ecbd9694458194e24f356ba9d37fc4f3a515c3dd#note_1402863 to fix this issue in GDM.

[Bug 1958488] Re: [nvidia][xorg] display hangs on boot LOGO
** Description changed:
[Impact]
- * In Ubuntu 20.04 (which using Xorg with proprietary nvidia driver), in some
cases, the nvidia driver will probe later than launching gdm.
+ * In Ubuntu 20.04 (either impish, jammy, upstream gdm) (which using Xorg
with proprietary nvidia driver), in some cases, the nvidia driver will probe
later than launching gdm.
* If above race condition happens in iGPU + nvidia cases and monitor
connects to dGPU, which will cause gdm starts with wayland as opposed to Xorg.
Which may lead the monitor stuck in black-screen or boot LOGO.
[Test Plan]
* The environment:
1. A desktop or workstation which containing an iGPU.
2. Plug a nvidia graphic card to the system and installing proprietary
nvidia driver (470 in my case)
3. Attach a monitor to dGPU and leave iGPU connect to nothing.
(in my test environment, there is the other ethernet card and TBT4 cards)
* Setup a cronjob,
e.g. @reboot /home/u/test.sh
* Have a test script in something like /home/u/test.sh as
#!/bin/bash
sleep 20
count="$(cat /home/ubuntu/count)"
count=$((count+1))
echo $count | tee /home/ubuntu/count
journalctl -b | grep -q -i wayland || sudo reboot
* the system will probably stuck in black-screen or boot LOGO.
* Before applying the fix, the fail rate is 6/24 (fail 6 time in 24 runs).
- * After applying the fix, it got pass within 90 reboot cycles.
+ * After applying the fix, it got pass within 1000+ reboot cycles.
+ * Test PPA can be found here
https://launchpad.net/~os369510/+archive/ubuntu/lp1958488
+
+ [Fix]
+ * The patch makes gpu-manager to probe nvidia (if needed) first and waiting
for the /run/u-d-c-nvidia-drm-was-loaded be touched by
71-u-d-c-gpu-detection.rules.
+ * Also, the gdm is using 61-gdm.rules to configure the gdm mode by checking
the nvidia driver presents or not.
+ * gpu-manager is before display-manager. Thus, gpu-manager will wait for
nvidia uevent be processed and then continue to work. When gdm be launched, the
targeted nvidia uevent has been processed already.
(71-u-d-c-gpu-detection.rules is later than 61-gdm.rules）
[Where problems could occur]
- * The patch checkes device/boot_vga with tag "master-of-seat". If a system
without any GPU as boot_vga then it will wait 10 seconds in the loop.
- * I tried to detach all monitors from the system and the boot_vga still
exist (default to use iGPU, the first device found during initialization)
- * I don't think they will a case which boot_vga doesn't exist in this moment
because:
- In drivers/gpu/vga/vgaarb.c (linux package)
- vga_arb_select_default_device() has a fallback function to determine the
boot_vga device to prevent firmware doesn't pass correct efifb to linux-kernel.
+ * there is not potential regression from my mind but it will lead the boot
time be longer.
+ * In my test cycles, it leads extra 0~1000ms in boot time. Usually, 0~200ms.
Worst case, over 1 s in 8xx runs (of 1000).
+ * I think the stability is important than performance in this case.
+
+ [Other Info]
+ * For non-ubuntu-desktop (which doesn't have gpu-manager), which using gdm
will meet this issue still. The other potential fix (from either gdm or logind)
is under discussion in
https://gitlab.gnome.org/GNOME/gdm/-/issues/763#note_1385786.

Test environment/steps:
1. A desktop or workstation which containing an iGPU.
2. Plug a nvidia graphic card to the system and installing proprietary nvidia
driver (470 in my case)
3. Attach a monitor to dGPU and leave iGPU connect to nothing.
(in my test environment, there is the other ethernet card and TBT4 cards)
4. Reboot system.
Based on:
$ cat /lib/udev/rules.d/61-gdm.rules
# disable Wayland on Hi1710 chipsets
ATTR{vendor}=="0x19e5", ATTR{device}=="0x1711",
RUN+="/usr/lib/gdm3/gdm-disable-wayland"
# disable Wayland when using the proprietary nvidia driver
DRIVER=="nvidia", RUN+="/usr/lib/gdm3/gdm-disable-wayland"
It will disable wayland by default if proprietary nvidia driver load.
But in some race condition cases, the nvidia probe is later than gnome
launches. (The fail rate is 6/24.)
Thus, ubuntu-gdm has a fix for Bug#1794280 to add
"ExecStartPre=@libexecdir@/gdm-wait-for-drm".
The gdm-wait-for-drm is intend to make sure all drm udev devices
enumerated before launching gdm.
It rely on at least one "master-of-seat" graphic card for gdm but it's not
rigorous enough.
Since most of graphic cards are own "master-of-seat"[1].
In my case, it detects the iGPU is probed but dGPU.
However, the display is attached to dGPU.
We need to make sure the targeted gpu (connecting to monitor) is probe
before launching gdm.

(in my test environment, there is the other ethernet card and TBT4 cards)
4. Reboot system.
Based on:
$ cat /lib/udev/rules.d/61-gdm.rules
# disable Wayland on Hi1710 chipsets
ATTR{vendor}=="0x19e5", ATTR{device}=="0x1711",
RUN+="/usr/lib/gdm3/gdm-disable-wayland"
# disable Wayland when using the proprietary nvidia driver
DRIVER=="nvidia", RUN+="/usr/lib/gdm3/gdm-disable-wayland"
It will disable wayland by default if proprietary nvidia driver load.
But in some race condition cases, the nvidia probe is later than gnome
launches. (The fail rate is 6/24.)
Thus, ubuntu-gdm has a fix for Bug#1794280 to add
"ExecStartPre=@libexecdir@/gdm-wait-for-drm".
The gdm-wait-for-drm is intend to make sure all drm udev devices
enumerated before launching gdm.
It rely on at least one "master-of-seat" graphic card for gdm but it's not
rigorous enough.
Since most of graphic cards are own "master-of-seat"[1].
In my case, it detects the iGPU is probed but dGPU.
However, the display is attached to dGPU.
We need to make sure the targeted gpu (connecting to monitor) is probe
before launching gdm.

the "gdm-wait-for-drm" is only maintain in ubuntu-focal also upstream doesn't use "gdm-disable-wayland" anymore but "gdm-runtime-config" instead.

[Bug 1958488] Re: [nvidia][xorg] display hangs on boot LOGO
** Description changed:
+ [Impact]
+
+ * In Ubuntu 20.04 (which using Xorg with proprietary nvidia driver), in some
cases, the nvidia driver will probe later than launching gdm.
+ * If above race condition happens in iGPU + nvidia cases and monitor
connects to dGPU, which will cause gdm starts with wayland as opposed to Xorg.
Which may lead the monitor stuck in black-screen or boot LOGO.
+
+ [Test Plan]
+
+ * The environment:
+ 1. A desktop or workstation which containing an iGPU.
+ 2. Plug a nvidia graphic card to the system and installing proprietary
+ nvidia driver (470 in my case)
+ 3. Attach a monitor to dGPU and leave iGPU connect to nothing.
+ (in my test environment, there is the other ethernet card and TBT4 cards)
+ * Setup a cronjob,
+e.g. @reboot /home/u/test.sh
+ * Have a test script in something like /home/u/test.sh as
+
+ #!/bin/bash
+
+ sleep 20
+ count="$(cat /home/u/count)"
+ count=$((count+1))
+ echo $count | tee /home/u/count
+ journalctl -b | grep -q -i wayland || sudo reboot
+
+ * the system will probably stuck in black-screen or boot LOGO.
+ * Before applying the fix, the fail rate is 6/24 (fail 6 time in 24 runs).
+ * After applying the fix, it got pass within 90 reboot cycles.
+
+ [Where problems could occur]
+ * The patch checkes device/boot_vga with tag "master-of-seat". If a system
without any GPU as boot_vga then it will fall in infinite loop.
+ * I tried to detach all monitors from the system and the boot_vga still
exist (default to use iGPU, the first device found during initialization)
+ * I don't think they will a case which boot_vga doesn't exist in this moment
because:
+ In drivers/gpu/vga/vgaarb.c (linux package)
+ vga_arb_select_default_device() has a fallback function to determine the
boot_vga device to prevent firmware doesn't pass correct efifb to linux-kernel.

[Bug 1958488] Re: [nvidia][xorg] display hangs on boot LOGO
Note that gnome-shell (which also renders the login screen for gdm) always uses the primary iGPU for rendering regardless of whether some monitors are plugged into a dGPU port. The latter get their framebuffers rendered on the iGPU but copied to the dGPU for output on every frame. This makes sense for the common dual-GPU case of a laptop where you want to be able to connect an external monitor to any port (even if that port is wired to dGPU) while still using the iGPU for efficiency by default. But enough from me. You should propose any patches to https://gitlab.gnome.org/GNOME/gdm/ (or to https://gitlab.gnome.org/GNOME/mutter) to get more authoritative information from the developers. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1958488 Title: [nvidia][xorg] display hangs on boot LOGO To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1958488/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
