If I'm debugging my graphics driver, I rely on the commandlines I can access by pressing Ctrl+Alt+F1-F6. However, after installing the latest NVIDIA drivers, the screen goes black when I switch to those TTYs. How can I get the TTYs to work with the NVIDIA drivers?
I tried some of the proposals from other questions, like the "closed as too localized" question here: How do I get my blacked out ttys back? and the very involved suggestion here: Can't view output in tty. (Ctrl+alt+f1 to f6 don't work, and display a black screen).
I'm running Ubuntu 14.04 with all the latest updates. Here's some system information:

Edit: I'm using the package nvidia-340 from the xorg-edgers PPA:
└─>apt-cache policy nvidia-340
nvidia-340:
Installed: 340.24-0ubuntu1~xedgers14.04.1
Candidate: 340.24-0ubuntu1~xedgers14.04.1

I also tried disabling the framebuffer as described here: http://forums.linuxmint.com/viewtopic.php?f=42&t=168108#p864284. Still no luck.
Edit: I'm now using the package nvidia-343 from the xorg-edgers PPA:
└─>apt-cache policy nvidia-343
nvidia-343:
Installed: 343.13-0ubuntu1~xedgers14.04.1
Still no luck.
First,
fix grub resolution:
Now, locate the line
and change it to this changing 1280x800 to the desired resolution:
Next,
add framebuffer (no, that's not a typo; use echo twice):
finally, update grub and initramfs:
reboot for the changes to take effect
Did you try installing the Lastest Nvidia Drivers using this link ?
http://www.binarytides.com/install-nvidia-drivers-ubuntu-14-04/
I have the lastest Nvidia and tty works fine on 14.04 64x. P.S: Are you using the standard kde (Unity) ?
First remove the xorg-edges drivers and pa from your system
Second go here: http://www.nvidia.com/Download/driverResults.aspx/78469/en-us
Third download the drivery
Give
Last but not least
I had the same issue after updating packages/kernel last night and installing these helped my nVidia card gets detected again:
Of course you can replace 311 with other versions in repositories, but I think what fixed it is
xserver-xorg-lts-raringThen run
It should show your card (earlier it wasn't showing for me).
have you also tried to download the driver for you specific device and run the installation through WINE? It's a possible route you could try. i have done the same when i ran ubuntu 13.10 and it wouldn't recognize my nVidia graphics card. i put the installation disk in and went to my computer and over the disk drive, right clicked 'run in wine.' then when the installation was done, i just adjusted ubuntu to the correct resolution and it worked for me. i just had to move the driver to C drive under drivers and restarted ubuntu. im not sure if this would work for all different devices, but it's worth a shot, if you ask me.
Have you tried using all the boot options?
nomodeset, noapic no1apic,
etc (the livecd provides the whole list, as does this link: https://help.ubuntu.com/community/BootOptions
When I had display problems I experimented with these until I found one that got me to a usable system. Then from there I was able to solve the problem and remove the boot option.
open this with your text editor
edit this to your resolution:
save and exit:
press ctrl+o to save
press ctrl+x to exit
update grub and reboot:
