Lately I find out that the ddcutil and ddccontrol doesn’t work, and as much as I tried to fix them … no luck. So I decided to remove Nvidia drivers, but somehow the Nouveau don’t load. I tried remove possible “blacklist” options I could find online [for example the files automatically created by Nvidia installer in /etc/modprobe.d/], but still lsmod | grep nouveau returns nothing.
What should I do?
I’m not sure about what this stuff means, but could this be the problem?
$ sudo modprobe -v nouveau
insmod /lib/modules/6.3.8-200.fc38.x86_64/kernel/drivers/media/cec/core/cec.ko.xz
insmod /lib/modules/6.3.8-200.fc38.x86_64/kernel/drivers/gpu/drm/display/drm_display_helper.ko.xz
insmod /lib/modules/6.3.8-200.fc38.x86_64/kernel/drivers/gpu/drm/ttm/ttm.ko.xz

insmod /lib/modules/6.3.8-200.fc38.x86_64/kernel/drivers/gpu/drm/nouveau/nouveau.ko.xz modeset=0 modeset=0
The last line those values being 0 instead of 1?
Reinstalling Fedora to the latest edition 38 did the trick. 
Awesome improvement to graphic stuff by default! Well done devs & co.
