I recently started getting a fuzzy screen on start up when booting into Fedora. The best way to describe it is to say the screen looks like it has a H-Scroll problem - fuzzy horizontal lines. The mouse pointer is stable however. My current work around is to log out and back in, then I get a nice stable login screen (difficult to do since you are clicking on menu items you cannot see properly). I´m looking for a permanent fix.

I had this exact issue on my machine where I am running both Fedora 20 x64 and Windows 8.1. Sometime in the summer I changed the GPU (Gigabyte GeForce GTX 750 Ti) to support two monitors both using the HDMI interface. Today I needed to switch onto Fedora and was surprised by the same fuzzy (corrupted) screen on both monitors (LG 22M45).

I did the following (below I list two links where I found the procedure):

  1. Ctrl + Alt + F4 at the fuzzy screen in order to bring up a terminal which was displayed correctly.

  2. Then I logged on and performed:

    sudo yum update

    Afterwards I did a reboot.

  3. Installed the nvidia drivers (the author of the solution recommends akmod instead of kmod):

    sudo yum install kmod-nvidia xorg-x11-drv-nvidia-libs

  4. Finally, I removed Nouveau from initramfs by performing:

    mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img

    and, also:

    dracut /boot/initramfs-$(uname -r).img $(uname -r)

Then, I did a reboot and the next time the Fedora logon screen appeared correctly.

Here is the original procedure. The same instructions, but more concise, are also here.
