I was using GTX 560 with nvidia's drivers in Ubuntu without problem. Then I have removed that video card and used Intel HD4000 for a week. After that I installed GTX 780, connected LCD with HDMI cable (no DVI on it) and it got weird.
The only resolution I have is 1024*720, SystemSettings--Displays calls my LCD a 'Laptop' and offers no options for it. SystemSettings--Software--Additional Drivers is empty.
I have tried installing nvidia driver packages from repositories with apt-get but it did no visible difference. X just does not pick them up. I just feel that writing xorg.conf in 2013 is not a right thing to do. Am I wrong?
Sure, I can just download NVIDIA drivers from their site, install drivers from binary, create xorg.conf file and be entitled to manual reinstallation of it with every kernel update. May be somebody can tell me a less awkward solution?
