Looking for modeline so that I can fix graphics card

gishaust · 02-08-2008, 03:11 AM

hi everyone

I have just looked at backtrack live cd that I got of the web.
in the opening choices the only choice that I could get to work was vesa 1024*768

I installed and all went well but when I restart the computer the screen shakes if I flux, startX, I can see the dragon but it is moving very quickly.

I found a site that can test the screen and it came up with "1024*768" 81.55 1024 1064 1168 1352 768 768 770 804

but i don't where do I put them I know that it is xorg.conf but where!!!

any help would be great

Add the mode lines as I have shown below

Code:

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes "1024x768" 81.55 1024 1064 1168 1352 768 768 770 804
        EndSubSection
EndSection

I'm assuming that the mode line you found is the one you want to use. Generally you can just use something like Modes "1280x1024" "1024x768"

thankyou for the reply

I have tried what you said and all it does is error in the log its says that 81.55 is not a valid keyword for this section.

if I take out everything after "1024*768" I can get it startx to work but the fuzz screen is back

Make sure it's "1024x768", not "1024*768". Also, is it a laptop or a desktop? What video card? Have you tried the driver(s) for the video card together with the mode line?

Yes it is a laptop. How do I get multiplication and not * on a laptop? How do I find out what the video card is linux?

It's the letter x lower case.

Open a terminal and type /sbin/lspci. There should be a line telling you about the video or graphics card. I'm assuming lspci is in the /sbin folder for your distro. If it's not there then type locate lspci and then type the path and the command, /path/to/lspci.
Here's the command from my laptop:

Code:

[glenn@toshiba ~]$ /sbin/lspci

Here's my xorg.conf / drivers:

Code:

        Driver      "kbd"
        Driver      "synaptics"
        Driver      "intel"

My video driver is intel.

Also modelines go to the Monitor section not the Screen one as it was stated earlier.

Correct usage:

Section "Monitor"
...
Modeline "1152x864" 139.84 1152 1232 1344 1520 864 865 868 920 (this is for mine, don't use it :P)
...
EndSection

Good catch pdw_hu. Sorry for the confusion gishaust.

gishaust · 02-08-2008, 09:46 PM

I have found out that ATI technologies Inc Radeon IGP 330m/340m/350m is the driver. IF I cat /etc/X11/Xorg.conf | grep Driver I get
Driver "kbd"
Driver "mouse"
Driver "ati"

pdw_hu Thanks for the pickup I put it in monitor instead of screen.

but its stills shaking

gishaust · 02-08-2008, 11:06 PM

maybe the answer???

I have been searching the web and found out that there can be an issue with
the above driver. But I found a site that said if I change ati to vesa in the xorg.config device it can work after compiling the kernel. I have never done this is it a good thing to do. When you think about it at the start of the thread the live cd vesa drivers is when it worked and the others could of been trying to install a ati card which seems to have a lot of issues.

What do you think???

any advice would be great.

gishaust · 02-10-2008, 02:56 PM

this has been fixed back track a the start asks you if you want to work under vesa if you don't xconfig at the start. it will work under the vesa drivers. Thanks for your help.
