Hi everyone,
few weeks ago, after a normal update on LEAP 15.4, i got a nasty problem at boot: long story short, the boot process goes without errors but I get no graphical login.
To go graphical, I need to log in as root, revert to runlevel 3 and then go again to runlevel 5, issuing
# init 3
# init 5
By the way, if I issue directly init 5, I got a blank screen in another virtual console and must go back to the previous console, set runlevel 3 and then 5.
This tells me that my video card is correctly managed, right? I have a nVidia with proprietary driver.
I really don’t know how to solve the problem.
I also don’t know what log could be useful to attach.
Reboot and before doing init 3/init 5 capture full output of “journalctl -b” as root and upload to https://susepaste.org. Then execute init 3/init 5 and provide the same output again, also upload.
Well, the first time sddm attempts to start Xorg server this server crashes. Also NVIDIA kernel drivers are being loaded when Xorg server begins startup. The second time Xorg server is started normally. It sounds like some race condition between loading of NVIDIA drivers and Xorg. You should now have to files - /var/log/Xorg.0.log and /var/log/Xorg.0.log.old. Could you upload them for comparison?
I will try myself to analyze the logs: maybe stopping X from starting before the nVidia driver is completely loaded could help? But being a dinosaur, and being grown up with the old initV I have no idea how to do it with systemd…
The sequence of events - Xorg starts, detects NVIDIA and unloads modesetting driver, then comes udev event that DRI device becomes available (as the result of loading nvidia-dri I assume), Xorg attempts to load modesetting driver again and crashes.
And here DRI device is available from the very beginning, so Xorg starts with preferred NVIDIA driver, it succeeds and modesetting driver is unloaded without initialization.
This sounds like upstream Xorg issue. You could try to report it to Xorg project.
maybe stopping X from starting before the nVidia driver is completely loaded could help?
Normally systemd-logind should wait until DRI device becomes available so display managers only attempt to start Xorg after this point, but using “nomodeset” disables this logic. Also I am not sure what triggers loading of NVIDIA kernel drivers.
You could try force loading of nvidia drivers early (see “man modules-load.d”) and removing “nomodeset” kernel command line.
Hi.
No news here. Tried a lot, with no luck.
I even tried to create a systemd service starting after the login message in the console to let it issue the init commands: nothing.
I tried removing nomodeset. Nothing.
I posted on Xorg issues board, no answer till now.
With systemd, the graphics driver should have been loaded before the GUI start job was queued – example with an AMD GPU and wait for Chrony to synchronise the system time –
# journalctl -b 0 --output=short-monotonic --no-hostname --system | grep -iE 'amdgpu|graphic|chrony'

As you can see, the Graphical Taget requires that, the Multi-User target has been reached, beforehand …
And, you can list the dependencies of the Graphical target –
Therefore, given systemd and, the way that systemd organises what starts when and, what a given unit needs before it is started, if, the Graphical target is reached before the NVIDIA drivers are properly loaded, there is something very wrong with the systemd Unit which loads the NVIDIA driver …
If plymouth and nvidia’s proprietary drivers are both installed, try removing plymouth, or at least disable it via linu line in Grub. I’m not sure which work, since I never have it installed:
plymouth=0
noplymouth
*]plymouth.enable=0
Maybe they all would work.
In case it helps, I am also experiencing this problem starting today (I also have nvidia drivers from the nvidia repository installed). I have been applying updates daily, as they come.
Did you guys fix the problem … because starting today i have the problem … again. I had something like this last october or november and fixed it by getting rid of nvidia. fast forward i want to try again and problem still persists.
System boots into a black blank screen with an underscore in the top left corner and a mouse pointer. Switch to virtual console, login as root, init 3 and init 5. Voila … everything works.
The only interestings things in my log i found so far are:
Feb 14 15:06:07 tuxedo-xps systemd-udevd[642]: /usr/lib/udev/rules.d/99-bumblebee-nvidia-dev.rules:10 Invalid value “/bin/bash -c ‘/bin/mknod -m 666 /dev/nvidia-uvm c $(grep nvidia-uvm /proc/devices | cut -d \ -f 1) 0;’” for RUN (char 51: invalid substitution type), ignoring.

So the bbswitch module is there it just doesnt seem to be found on the first try for some reason.
