I met the same problem on my fedora, though not knowing the reason, I solved it by add nouveau into blacklist.
?1????????nouveau ? ?su?????root???:
- su root
- vim /lib/modprobe.d/dist-blacklist.conf`
?nvidiafb????
#blacklist nvidiafb?????????
blacklist nouveau
options nouveau modeset=0
?2? ??initramfs image????????
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak
dracut -v /boot/initramfs-$(uname -r).img $(uname -r)
?4???????????nouveau??????
lsmod | grep nouveau
?????????????
I forgot where i find this way, and manage to solve many problems with GUI (you must repeat the operation everytime you update the kernel)
``` (1)forbiid nouveau
su root
vim/lib/modprobe.d/dist-blacklist.conf
add # before blacklist nvidiafb
#blacklist nvidiafb
then insert:
blacklist nouveau
options nouveau modeset=0
(2)rebuild initramfs image?recommend copy directly?
mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.bak
dracut -v /boot/initramfs-$(uname -r).img $(uname -r)
(4)then after computer, restarted
lsmod | grep nouveau
it will ok if there is not any output
