I used the net-installer package yesterday to install fedora 22 with the cinnamon desktop. That installer was buggy but I eventually got it to do the install. I then went to install my nvidia drivers. First I tried the run file install and no matter what I did the driver kept detecting nouveau running on my system. This was even after I did the minimal install and had not yet added any graphics or window managers. I followed the following steps to disable nouveau...
dracut --omit-drivers nouveau /boot/initramfs-$(uname -r).img $(uname -r) --force systemctl disable gdm reboot
These did not seem to do anything.
I gave up with the run file and decided to use the rpmfusion packages instead. I installed the drive like this and it seemed to work.
sudo dnf install xorg-x11-drv-nvidia sudo dnf install xorg-x11-drv-nvidia-libs.i686
This time it seemed to install well. When I rebooted the system I made it to the login screen with no problem. However once I logged in cinnamon displayed some message about how it had crashed. I then installed some other window managers and these would not open either.
I also tried installing the driver with a few other ways I found on the internet and all of the installs either did not work or caused it to crash in the same way. I am using and Nvidia GTX 960 for my display along with a GTX 720 (no display just for debugging CUDA applications). Does anyone know how to make it work?
