I am installing slackware 8.1 on a Dell Gx200 with a NVIDIA RIVA TNT2 Model 64 video card and a Trinitron Multiscan 20se II monitor. The monitor is a 21 inch. When I run startx I get the same error 'no screens found'. I searched the other forums came across the same stuff. I believe the video card is 8mg and is onboard. The monitor I'm not sure of the all the specs so when I run xf86config I may be getting the resolution wrong. Anyone have any suggestions or ideas?

Well I would first suggest trying to enable VESA mode operation. There is a default X11 config provided. Just copy it to the XF86Config, then attempt to startx.

cp /etc/X11/XF86Config-vesa /etc/X11/XF86Config

If it still reports the same error message then I would suggest attempting to use the framebuffer device. Similar to the above, except it also requires vga=791 in the /etc/lilo.conf to be set for 1024x768x64k. Run lilo to write the new boot record and reboot. Then copy the default fb config file.

cp /etc/X11/XF86Config-fbdev /etc/X11/XF86Config

Then startx. I have had this to work when everything else fails to at least get X running even with LCD panels and notebooks.

Once you have a usable system and everything is stable, then you should look into the nVidia module drivers for better performance. Not sure here but I think that on 8 MB ram for video 1200x1024, true color is about the maximum that can be run. Lowering the color depth can increase the maximum desktop resolution.

That usually means that you don't have a screen definition that is compatible with your hardware.

1. Make sure you use the correct Horizontal and Vertical frequencies for your monitor. If you don't have the manual try monitorworld.com they have specs for most monitors.

2. List several resolutions and color depths in your screen section of XF86Config to increase the likelihood that the X server can find a usable one.

I have an TNT card and it works OK with the nv driver that comes wit XFree86
