Newbie Linux user here. I just installed Ubuntu 12.10, dual booting with Windows 8 Preview Release Build 8400 on a Dell Precision 490 workstation with Nvidia Quandro NVS 55/280 PCI graphics card.

I cannot login to Ubuntu - after entering my password and pressing enter, the screen graphics gets garbled for a few seconds, and then the screen goes black showing only the mouse cursor. I suspect it's something to do with my Graphics Card, everything on the GUI login screen feels very sluggish.

I know what I have provided here doesn't give you much information, would appreciate it if I could get some guidance on how to provide more useful logs.

Thank you.

Here is a link to a answer on how to install drivers if you can't access ubuntu. – Seth Dec 12 '12 at 3:08
Try booting with nomodeset. To do this, when you get to the Grub menu, select Advanced Options, then the second Recovery mode entry, and then select Resume normal boot. After that install a graphics driver from additional-drivers. – bcbc Dec 12 '12 at 4:31
@iSeth I tried that link, but when I got to "Additional Drivers" tab, the list was blank. Couldn't find anything to install. – mchangun Dec 12 '12 at 15:54
what graphics card do you have? – Seth Dec 12 '12 at 16:21

The Ubuntu X team has created a stable PPA for the Quadro NVS 160M that should work with your graphics card too.

To Install it follow these instructions.

First you need to add the PPA.

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

Then Update the package list and install the driver

sudo apt-get update && sudo apt-get install nvidia-current nvidia-settings

Then reboot the computer with sudo reboot
