I have recently reinstalled Fedora 37 KDE spin due to many issues when installing the proprietary Nvidia driver.
As soon as I install the Nvidia driver and boot up the computer, sddm does not start, but only a black screen with a functional mouse curser appears. So I can not even log in properly.
I have to switch to tty3 or tty4,… to log in and startxstartx, KDE starts normally, no issue so far (except diagonal tearing on an external monitor as mentioned here: Diagonal Screen Tearing since 525.78.01 - Thinkpad P1 Gen2 T2000 - #6 by fhortner )
So I decided to completely uninstall the nvidia driver.
As soon as the Nvidia driver is installed again, SDDM also does not work anymore.
I already tried to add
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
to /etc/sddm/Xsetup
nvidia-bug-report ran from tty3 before startx was executednvidia-bug-report.log.gz (140.9 KB)
When loging in on tty3, I can restart sddm via
sudo systemctl restart sddm
or
sudo systemctl restart lightdm
and sddm/lightdm starts on tty2.
SELinux is preventing gdb from ‘read’ accesses on the chr_file nvidiactl .
The is no issue when using nouveau driver (where I have massive diagonal screen tearing. Thus I can not run nouveau regularly).

The nvidia driver is loading too late, please try embedding it into the initrd. Should be like this:https://www.suse.com/support/kb/doc/?id=000019945
Strange thing is, no issue with Fedora 36.
We checked and reinstalled F36 with Nvidia 525.89.02 - no issue with SDDM under F36
Upgrade to Fedora 37 and again SDDM does not start.
removing
nvidia-drm.modeset-1
and
initcall_blacklist=simpledrm_platform_driver_init
from the kernel parameter did the trick.
