Could you elaborate on how you reinstalled the drivers, have you used the cli or gui?
eg what does
mhwd output? That would give an idea on what is installed, for nvidia you need video-nvidia installed for nvidia supported cards.
See the mhwd --help for options to remove and install
Documentation for installing graphics cards
Hard to read the log 
There is a mention of fb this is probably not correct, but I hope a more knowledgeable user will confirm.
edit: the type of card would be usefull for troubleshooting, depending on the type the install differs between the nvidia supported drivers and the not supported drivers.
