Problem with resolution

[MasterN64]

When it boots I Hit f2 and put in the standard screen=1024x768 command and it defaults to 800x600. However if I put in screen=1280x1024 it works and puts it at 1280x1024.

Im using the latest version and boot from a CD.

Here are my specs incase they help.

Radeon 7500
K7VZA MoBo with latest bios
Everythign else works fin so it shouldnt be a problem.

I have no idea whats wrong or what could be wrong. It doesnt make sense to me why it would work with the higher resolution but not the lower one.

And i have tried the fb1024x768 command to. It didnt work.

[edit] Just want to note that 1280x1024 is not supported by my monitor and is jsut too big of a resolution for my small monitor so i have a problem wiht running it at that res. I also have Win2k set for 1024 and cant switch it to 1280. So even if i did run it at that i would have to constantly tweak my monitor.

Try using xvrefresh=60 it is probably trying to use to high a refresh rate you may also want to include noddc to stop auto-detection of the monitor and you could try xmodule=radeon for the card.

I tried all of those and most combinations of them. None of them worked. I even tried xmodule=ati.

Here are some examples of what ive put in.

knoppix screen=1024x768 xvrefresh=60 xmodule=radeon noddc noeject noprompt

knoppix screen=1024x768 xvrefresh=60 xmodule=ati noddc noeject noprompt

And then i tried them wihout the noddc and wihtout the noeject and noprompt. Still didnt work.

Is there anything else i should do pr is there somethign wrong with how im putting the commands in?

You are using the cheat codes properly there's only a couple more things I can think of try knoppix fb1024x768 xmodule=fbdev this tells knoppix to use the frame buffer for the screen size and the frame buffer device for the display or knoppix expert and go through the configuration and see if it works.

Re-reading your first post I notice the 1280x1024 worked and you say the monitor does not support that are you sure it did not fallback to 1024x768 when you tried it. You may want to try it again and go into the Info Center and check the X-Server and check the actual resolution being used it is in the System menu.

You could also try to configure the display in the Control Center -> Peripherals -> X-Display and go through configuring the display then open a console window and sudo init 2 to go to the terminal and while there either sudo init 5 or sudo /etc/init.d/xsession start to re-sart the Xserver with the saved settings from the configuration you just completed.

Thank you so much for all your help!

It seems I had tried the fb1024x768 but I had forgot to put in the command xmodule=fbdev. When I put woth together it worked.

knoppix xmodule=fbdev fb1024x768 xvrefresh=60 noprompt noeject

That is what got it to work with me.

Thanks again!
