</span>I recently had a problem with the nvidia-340xx. I would only get a blank screen with no X<br>
being started. I did not check the logs I just did what has worked for me in the past.<br>
<br>
1. dnf erase *nvidia*<br>
2. reboot (You could either boot to gui using nouveau or multi-user mode)<br>
3. dnf install akmod-nvidia-340xx (In your case akmod-nvidia-304xx<br>
4. reboot<br>
<br>
There is nothing to lose by trying this.<br>
