No suitable X-Server found for Matrox G400

Hi!

I'm trying to boot Knoppix 3.2 2003-06-06-BETA from floppy/CD, but get the following error:

Quote:

Starting X11... root@tty1 [/]#..
Retrying with Server XFree86(vesa)
Error: No suitable X-Server found for your card..
Retrying with Server XFree86(fbdev).

and a lot of blinking (problably trying to change displaymode?).

My card is a Matrox Millenium G400 AGP 32Mb. I can boot and run Knoppix 3.1 2003-01-20-BETA and Knoppix 3.2 2003-03-28-BETA without problems, but havent tried the intervening relases, so I don't know exactly when the problem has started.

My motherboard is an ASUS P5A with AMD K6-2 400 proc.

I can press Enter after the error and give the command "lspci -v", but I don't know how to redirect its output to a file on the floppy or my HD. So I can't give complete output of lspci, but the Graphics controller part says:

VGA compatible controller: Matrox Graphics, Inc. MGA G400 AGP (rev 03) (prog-if 00 [VGA])

This is my setup on the boot floppy, and it should be default values except for lang=en keyboard=da wheelmouse xkeyboard=dk:

Quote:

DEFAULT vmlinuz
APPEND ramdisk_size=100000 init=/etc/init lang=en keyboard=da wheelmouse xkeyboard=dk apm=power-off hda=scsi hdb=scsi hdc=scsi hdd=scsi hde=scsi hdf=scsi hdg=scsi hdh=scsi vga=791 initrd=miniroot.gz nomce quiet BOOT_IMAGE=knoppix

Can anyone help?

Stig.

Try adding xserver=XF86_SVGA and xmodule=mga also you will not need the wheelmouse cheat code it is the default now.

Thanks Stephen, that got me at least up and running. But not in a very impressive video mode. I'm not sure which mode it is... In Control Center -> Peripherals -> Display it says 640x480/75Hz, 8 bit. I'm not sure that is correct (I'm actually pretty damn sure the refresh rate is much lower), maybe its 800x600, 4bit. But for sure its not very impressive and its not like it used to be in previous Knoppix releases I have tried. How do I get it to start in 1024x768, 24 bit? I've already tried setting screen=1024x768 and vsync=85, but that doesn't seem to help?

I never trust what that is telling you the only way to really see what mode you are running is to check in the file /etc/X11/XF86Config-4 and look at the bottom of the monitor section for the ModeLine and the top of the screen section for your depth, knoppix defaults to a depth of 16 bit I don't think there is a cheat code to change that on CD boot.

Try knoppix xserver=XF86_SVGA xmodule=mga xvrefresh=85 screen=1024x768 noddc you may also want to try the expert cheat code to set your video you know what your card and monitor are capable of so just put in your settings where needed.

Hi again

I'm still in trouble :-(

I only see a list of modes, but no indication of what mode I'm actually running?

Allright. It's not important either. But right now I'm running with so few colors that the colorfade effect on the title-bars are dithered, and the screenflicker is annoying too.

Didn't help :-(

I tried that, but don't think I'm expert enough. I know what my videocard and monitor are capable off, but couldn't find out how to specify it. I choose to set my own videosettings - I thought - but it didn't give me the change anyway :-/

BTW, my monitor might not be correctly detected either. I have a Samsung SyncMaster 900SL Plus, but Knoppix thinks its a "SAM4279"? Well, maybe its the same thing? Anyway, even if the detected monitor shouldn't be able to display high resolutions, it sounds weird it also choose a mode with only 256 colors (I've would had guess it was something in between 16 and 256 colors, but I don't think such modes exists?).

When I go into Control Center -> Peripherals -> Display I have the choice to select different videocards, monitors and modes, but I have to restart "my session" to make the changes take effect. The only way I know of doing that, is to reboot Knoppix, and then I loose the changes I've just made... Is there some way I can restart X without rebooting Knoppix completely? (I asume "restart session" means restart X?) It would make it much easier to experiment.

But well... My primary reason to want to boot Knoppix at the moment is to check some webpages in Konqueror. I can do that now, so its no big deal actually. If theres no more bright ideas to what I can try, I can live with it as it is now, and just hope it gets better in a later release.

Thanks for trying :-)

At the bottom of the ModeLine's you will see a section similar to these for my monitor these are the ones being used.

Code:

vendorname "Acer Peripherals" modelname "54e" ModeLine "1024x768/65Hz" 65 1024 1032 1176 1344 768 771 777 806 -HSync -VSync ModeLine "800x600/72Hz" 50 800 856 976 1040 600 637 643 666 +HSync +VSync EndSection

My monitor is also never detected correctly on when I boot from the CD.

You can go through the Xdisplay and configure for your monitor and video card after you are done open a console window and sudo init 3 to take you to the console itself without X running in effect the same as re-starting the Xserver but not shutting down then while at the console /etc/init.d/xsession start will start the knoppix Xsession again with the new settings that you had saved in the config process with Xdisplay. Also some other cheat codes you may want to try knoppix vga=normal with maybe your xmodule and xvrefresh cheat code and have you tried any of the fb images like fb1024x768 note: you do not need to put the knoppix in front of this.
