If you want to install the nvidia driver better use this guide, it is more concise http://rpmfusion.org/Howto/nVidia When you install nvidia* driver packages it modifies /boot/grub2/grub.cfg (it's /boot/efi/EFI/fedora/grub.cfg on UEFI systems) to make sure the nouveau module isn't loaded at boot; uninstalling those packages should have reverted the changes to grub.cfg. If you uninstalled the nvidia packages and the display isn't using the full HD resolution as before, chances are the changes in grub.cfg weren't reverted, so check that file and remove these bit: nouveau.modeset=0 rd.driver.blacklist=nouveau video=vesa:off If you decide to try the nvidia driver again and it still doesn't work, after you boot post the contents of /var/log/Xorg.0.log to http://fpaste.org and post a link to it here; or you can use this command: fpaste /var/log/Xorg.0.log -- Ahmad Samir
