Hi, I have an asus GL502VS laptop that has a GTX 1070m and kde. I have installed the latest nvidia driver and the startup time is very long displaying a black screen. After 1m30 the connection window appears.
Whatâs visible in the logs, its doing nothing for 90 seconds. This makes me suspect systemd is trying to start some daemon, it doesnât work so it times out. This would only be visible in the journal, which is not included in nvidia-bug-report.log.
Please check your journal
sudo journalctl -b0
for whatâs hanging.
I attach the result of the command.
There are errors like : ânvidia : module verification failed : signature and/or required key missing - tainting kernelâ
ânvidia: Process â/usr/bin/bash -c â/usr/bin/mknod -Z -m 666 /dev/nvidiactl c 195 255ââ failed with exit code 1â

For your information, if I change the âacpi_backlight=nativeâ parameter to âacpi_backlight=vendorâ in the grub the logon window is displayed quickly.
As a result, the brightness control does not work anymore.
