I recently installed a new NVIDIA card GK106 [GeForce GTX 660]. I tried to install the nvidia drivers and didn't see anything different but once I restarted i cannot get any GUI. I can ctrl+alt+f2 and get to a terminal. I've tried to remove all Nvidia drivers but still that's no help.

I'm still a novice by most standards so any help is greatly appreciated!

you said you tried to install the nvidia driver ?

if you did NOT read the fedora install instructions and user guide you will find that that is hard to do unless you fallow the INSTRUCTIONS
http://docs.fedoraproject.org/en-US/...ide/index.html
release notes
http://docs.fedoraproject.org/en-US/...tes/index.html
http://docs.fedoraproject.org/en-US/...ide/index.html

have a look at the fedoraforum nvidia guide
http://www.forums.fedoraforum.org/sh...d.php?t=280750
and at the TOP of EVERY page on the forum is a bold yellow link to guides
and the very FIRST one is "mjmwired"

Above is the what I found for installing and uninstalling which is what I have tried. I admit I should have came here first but thought I could find a faster solution by going to Google and I'm now paying the price. I hate to have to re-image my machine especially because anytime I mess it up my wife insist I go back to windows!

Thank you for the great information (I never thought about first). I am getting some errors when I issue "yum grouplist -v hidden | grep desktop"

root@localhost ~]# yum grouplist -v hidden | grep desktop

Could this be part of my problem?

??????????????????????????????
what is it you are doing ?

and where did you get those very odd and weird commands
( and change the "odd" command that are on "if-not-true-then-false"
that first one ??? "yum grouplist -v hidden | grep desktop"
mind bogglingly odd

i would really use the operating system's forum than some random webpage
"http://www.if-not-true-then-false.com/2014/fedora-20-nvidia-guide/"

"if-not-true-then-false" sometimes is fine

but , use the official fedora guide
on fedoraforum


This error
i am guessing you used ONLY "su" to become root

fedora uses TWO very different commands to become root
"su"
and
"su -"
that "-" makes a VERY big difference
su = root BUT!!! with the NORMAL users' $PATH and OLNY using the normal users settings
( only PARTLY the root administrators account )

su - = ROOT and with the full ROOT $PATH
and full root settings

there is a SAFETY check in gnome
the GUI really SHOULD NOT !!! be ran as root ( very big security MESS )

you have to use "su -" or the long version of that shortcut " su -l root" to be able to do most things as root

How did you manage to get 6 kernels installed

fedora defaults to 3
the current one being used
the last as a back up
and the one before that as an EMERGENCY back up


can you post the output of these two commands

Thanks for all your help! After seeing your post as well as others I've choosen to just re-intsll Fedora 20 on my desktop.

Thanks again for your help!
