Oh dear i seem to have cockedup somewhat.

Running Ubuntu ( Hoary )

My Nvidia card fried on me so i wanted a replacement as soon as, so i went and bought an ATI Radeon 9550 guru.

At the console log in as root and type XFdrake and select your new video card.

Then type startx and you should be back at a graphical desktop.

That does not work ( command not found ) is that not for Mandrake?

Sorry thats the first I heard of Ubuntu try running a search on google though I will research it for you and post back if I find anything. "Mandrake is not a bad choice though for a newbie" you may want to try it.

edit your /etc/X11/xorg.conf file (as root) and change this:

Code:

Section "Device"
    Driver      "nv" (or possibly "nvidia")

to this:

Code:

Section "Device"
    Driver      "vesa"

This should get X up and running again.

edit: try "pico /etc/X11/xorg.conf", or "mcedit /etc/X11/xorg.conf", lastly "vim /etc/X11/xorg.conf"

type "man [command name]" for instructions!

Thankyou,thankyou, i have now got back in.

Is that it, or is there anything else i should need to do , because although i am in, i do not think things are right as i cannot change resolution, if i do the screen just gets all garbled up.

nice one.
If you look more closely at the file you edited you will see that it contains all the information the "X" windowing system needs including:
driver details (Device section(s))
screen resolution and colour depth (Screen section(s))
monitor type and refresh rate range (Monitor section(s))
keyboard & mouse (Input Device sections)

Drivers can usually be found on the manufacturers website (for linux) and are required for 3d accelerated graphics. It also needs to be declared in the "Driver" section of your xorg.conf file (like "nv" for nvidia) - read the "README" file for your driver for full info.
Radeon drivers aren't yet up to scratch, nvidia drivers on the other hand are a doddle.
For best results with screen resolution, read "man gtf" then try this for starters:

Code:

$ gtf 1024 768 75
  # 1024x768 @ 75.00 Hz (GTF) hsync: 60.15 kHz; pclk: 81.80 MHz
  Modeline "1024x768_75.00"  81.80  1024 1080 1192 1360  768 769 772 802  -HSync +Vsync

copy and paste YOUR output to the "Monitor" section of your xorg.conf, then edit it to match the resolution decalred in the "Screen" section thus:

Code:

Section "Monitor"
    Modeline "1024x768"  81.80  1024 1080 1192 1360  768 769 772 802  -HSync +Vsync

if "1024x768" is mentioned here:

Code:

    Subsection "Display"
        Depth       8
        Modes "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       16
        Modes "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       24
        Modes "1024x768" "800x600" "640x480"
    EndSubsection
    Subsection "Display"
        Depth       32
        Modes "1024x768" "800x600" "640x480"
    EndSubsection

As you can see there are many ways of tweaking your graphics. Enjoy!

Tuttle Thanks for the (how to) i will print it off for future reference.
I was not happy for some reason with the ATI card so i have bought another Nvidia card, i believe the drivers are more linux friendly than ATI's offerings, (i maybe wrong).

But i have totally screwed up the install know, because of the constant changes, so as i have had it only installed for a week or so i am just reinstalling Ubuntu.

Once agin thanks for the help. I know no where to next time i screw things up.

Such a lot to learn and get used to.
