as you can see, this directory has *.conf file from /etc/modprobe.d/ about nvidia
and the grub is from /etc/default/grub
for some how, I found that the kde will loop detect the volumes device, so I create the disable-nvidia-hdmi.conf
I try to find the error log myself, and storage the log into:
- journalctl.1.txt:
journalctl --user -b | grep -iE 'kwin|plasmashell|nvidia - journalctl.2.txt: `sudo journalctl -k | grep -i nvidia'
- xsession-errors:
cat ~/.xsession-errors, and I launch the plasma x11 at 21:04(my time region)
