Nvidia video driver 4.15.18 install complete but cannot boot in GUI desktop

My desktop OS is fedora 29.I install the latest video driver for my GTX 750ti(4.15.18) with no error…But when I reboot,I can’t log into my GUI desktop as before.

Works fine here.

Where’s your NVIDIA bug report?

I suspect you haven’t blacklisted nouveau and thus your NVIDIA driver cannot load. Also, you might wanna try using RPMFusion instead of installing the driver manually using a *.run file which is rarely a correct decision.

Here is my nouveau block file content:

generated by nvidia-installer

blacklist nouveau
options nouveau modeset=0

video driver 4.15.13 works fine in the same situation.

It works for me by this way.

1.Boot to single user mode.
2.uninstall old video driver.
3.reboot to single user mode again.
4.install new video driver and create a xorg.conf file at end of installation.
5.type exit to continue boot to desktop.
6.run nvidia-settings as root and save all new options to xorg.conf.
7.reboot then all are ok.
