Yesterday I got a Nvidia GTX 750ti for my htpc (ubuntu headless 12.04) but the computer wont boot with it installed. I've tried booting with nomodeset parameter and installing the latest beta driver from nvidia but I get black screen on boot. The machine does not seem to boot as I cannot ssh into it or invoke ctrl-alt-f*
I have ubuntu 13.04 64 bit and same problem: Nvidia GTX 750ti and no boot.
if you have trouble at reboot you can do a new reboot and start in recovery mode:
after this if you continue by the normal boot you can login in graphical mode but after you are logged in you have to repeat step 7,8,9
at next login you can boot on graphical mode.
this procedure has worked for me I hope work for you too.
I too have had some issues with the new Nvidia cards. Here's more commands that helped me.
boot in recovery mode with networking on.
navigate to your home directory.
download Nvidia 750ti drivers... If you've got a different card, like a 760ti or 780ti check Nvidia's website when you go to download the driver, the 'Agree and Download" button is the link I used for the wget command below. If the drivers are different, (I don't think they are) this may solve some issues for others as well.
Then continue were Leonardo left off above. Thanks man, I'd +1 if I could.
After booting with nomodeset and installing ubuntu then only follow step 7 & 8 from Leonardo Saracini
then add following ppa;
restart and voila ;) (by the way I'm using 14.04)
This can be fixed by going:
