# Graphics card replaced - problems with drivers at start up

Hello

My laptop just got its motherboard replaced because the connection to the docking station had gone. I was told that the hardware was exactly the same (the repair was taken care of by the IT department), but I face problems when booting Fedora:

The system did not reach the log in screen but was instead hangs displaying what looks like tty with all kind of stuff that has been loaded. I had similar problems with nvidia drivers when installing fedora so this seems to be related. At that time I installed the kmod drivers (see the old question and answer here). It was suggested somewhere to remove the Xorg.conf file which resulted in the screen saying "Something has gone wrong and the system cannot recover" on start up. When pressing the Log Out button nothing happens.

By running lspci | grep VGA I found that the graphics card is an GF108GLM (NVS 5200M), which seems to be the same as the one I had previously.

I had a look at the /var/log/Xorg.0.log and found the following errors:

• Failed to load module nv (module does not exist)
• [drm] KMS not enabled
• Failed to initialize GLX extension (compatible NVIDIA X driver not found)

It seems to me that the problem is with the graphics card drivers and the fact that I have got new hardware (even though it should be the same). However, I haven't got much clue on what to do to solve the problem or where the problem actually lies so any help is much appreciated.

I am running Fedora 20 on a Dell latitude with i7 processor and 64-bit OS in dual-boot with Windows which has no problems starting up. The system and drivers should be up to date.

UPDATE: I now tried removing kmod and xorg-x11-drv-nvidia\ * and installing akmod which as a dependency also reinstalled xorg-x11-drv-nvidia (as far as I could see). This recreated the xorg.conf file. The error in xorg.0.log is now 'N o devices detected' and 'No screens found'. I tried to run X -configure which returned the error: Number of screens do not match. After reboot I am back to the 'No devices detected' error in Xorg.0.log. So I am still stuck. Any help is much appreciated!!
UPDATE 2: I now removed all related to nvidia by yum remove \*nvidia\* and I can now boot to desktop as normal. The only problem that remains is that there is a lag on text and mouse on my external screens, related but not as bad as my problem when I installed Fedora, here. Following the procedure that helped me then results in the problems described above. Maybe a full reinstall of fedora would do the trick? Or maybe just an upgrade to a different version of Fedora?
