Cant boot after ATI proprietary driver install

[Muximori]

Since the easy install driver worked on a previous system, I simply downloaded the fglrx package, went to system settings and choose "restricted driver". Now, whenever I try to boot, the system hangs on a blank screen. In recovery mode, typing "fglrx-info" returns "Cannot open device :0".

How do I roll back to the previous driver from recovery mode?

I simply downloaded the fglrx package

From where ?
Is this from repositories or from AMD(Ati)

In recovery mode, typing "fglrx-info" returns "Cannot open device :0"

I think that recovery mode use vesa drivers.

Now, whenever I try to boot, the system hangs on a blank screen.

You could try:

Blank screen: press Ctrl + Alt + F1 (or F2...6). This will start virtual console.

From Virtual console
http://en.wikipedia.org/wiki/Virtual_console

a virtual console (VC, sometimes virtual terminal, VT) is a conceptual combination of the keyboard and the display for a user interface. The concrete combination is the system console of the computer, where the user can switch between the virtual consoles to access multiple unrelated user interfaces. Usually in Linux, the first six virtual consoles provide a text terminal with a login prompt to a unix shell. The graphical X Window System starts in the seventh virtual console.

Log in and

sudo dpkg-reconfigure -phigh xserver-xorg

this will make new xorg.conf with default options.

Re: Cant boot after ATI proprietary driver install

I downloaded the package from the repository through adept.

I tried sudo dpkg-reconfigure -phigh xserver-xorg, only to get an error when I startx. I'm not sure what else the driver install affected that could be screwing it up, is there any way to roll back the installation with apt-get?

What kind of error ?

What happen if you:

sudo /etc/init.d/kdm restart

is there any way to roll back the installation with apt-get?

Well - there is no need to. After installation you need to edit xorg.conf (Xorg.conf is xorg X Window System server configuration file) and tell that you want to use fglrx driver. That is: "System -> Administration -> Restricted Drivers Manager" and select "ATI accelerated graphics driver".

sudo dpkg-reconfigure -phigh xserver-xorg should reset the situation so that kubuntu is using safe drivers (non proprietary).

You could also try:

sudo dpkg-reconfigure xserver-xorg

This reconfigures xorg (ask questions - what you want to do).

Here is good page of sudo dpkg-reconfigure xserver-xorg:

Thanks for the help, I fixed the problem by simply reinstalling kubuntu.
