More info on the undefined mode number. During some testing on an HP vectra pIII 733 I ran the scan instead of pressing space to go on (when I pressed enter I was presented with a list of modes and when I ran the scan I was presented with the same list so I assumed that the list was what it had originally found the system could handle). I tested some of the modes (just chose a number 0 then 1 then 2 etc...) and what I found was that the mode was used for the rows and columns for the console terminal (didn't affect the virtual X terminal). I then added the code for 80x25 to the boot line vga=0f00 and the undefined mode problem disapeared. I also tried the 132x80 (not sure if those were the exact numbers or not but close enough for this explanation) and it worked it is just that the text was pretty small (but as I stated it did not affect the 800x600 X terminal once it came up). If I switched to terminal 1 the text was small but when I switched back to vt5 the X terminal was normal.

The short version of this is that to get rid of the undefined mode set vga=<whatever mode you want for the console terminal text i.e 0f00 for text screen 80x25>. This will probably only work for hard drive installs because it would appear that the vga code is used by the knoppix scripts to avoid the need for running xsetup at each boot (I may be wrong about that point as I don't run liveCD or frugal so I am not sure about that but I do know that on an HD install this works).

I just purchased a dell gx100 pIII 700 and with the grapjics card that is in it I can't run in 1024x768x24. If I choose 800x600x24 the icons show up. Run xsetup until you get the right combo that works.

I just tried that on my GX100 and it worked.

I think it it has to do with the cutdown xserver that DSL uses, because I previously had Puppy linux installed on this machine and it runs xorg with no problems in 1024x768x24.

So far the only other advice I've seen to fix this problem is to use Xfree86 and try to find a configuration from the net, or copy the configuration file from a "full" distro - I haven't had success with either suggestion.

Has anybody installed and used xorg with DSL?
