Is this similar to: Failed to set mode on CRTC:10? –  user25656 Jan 24 '13 at 10:13

I recently had the same problem on an HP as well. I believe it is an issue with the video driver. I corrected the issue by re-installing the correct driver.

From the error message, get to the terminal by crtl+alt+f1(login/password)

Verify your video card type (prob Nvidia or ATI)

sudo lshw -C video

After you verify your card, just a simple apt-get install

sudo apt-get install nvidia-current

*install the needed video driver if diffrent from Nvidia.

after the install sudo reboot

I hope this helps!

If you have more than one external monitor plugged in, see this bug which suggests booting with one of your monitors unplugged. Worked for me.

Running sudo apt-get install nvidia-current solved my problem on an old Compaq Presario SR2010NX using a NVidia GeForce 6150 LE on-board video chip. This was Xubuntu 12.04 LTS.

The install went smoothly, but I got "failed to set mode CRTC:6" when booting and had to start X manually.
