No graphics on Dell Inspiron 510m

[frog-x]

I work at a university and we're develpoing a Knoppix remaster which we've given out to some students to test. We've got one student with a Dell Inspiron 510m (bought last summer) and we just can't get the graphics to work. It uses integrated Intel graphics 82852/82855 GM/GME. This is correctly recognised when Knoppix is booting, and it tries to use the i810 module, which would seem to be sensible. However, when Knoppix tries to start the X server, we get:

[drm:drm_init] *ERROR* Cannot initialise the agpgart module
..
Retrying with Server XFree86(vesa)
Retrying with Server XFree86(fbdev)
Error: No suitable X-Server found for you card


I've tried starting with "failsafe", "knoppix26", "fb800x600" etc. but it still doesn't work. Our remaster is based on Knoppix 3.4 but I've tried with an unaltered Knoppix 3.6, and 3.7 and still get the same result. Any ideas why it isn't working even though it correctly identifies the graphics chipset???

many thanks...

There has been a fair amount of posts on problems with integrated graphics.
Have you tried cheat code "knoppix xmodule=i810" at boot?

I don't have one of these boards but as i said I have seen several
posts complaining about no xserver with them. http://www.google.com/custom?domains=www.knoppix.net&q=integrated+Intel+graphics+82852%2F82855+GM%2FGME +knoppix&sitesearch=&sa=Search&client=pub-3822347126027973&forid=1&ie=UTF-8&oe=UTF-8&cof=GALT%3A%23E9382F%3BGL%3A1%3BDIV%3A%23CCCCCC%3B VLC%3A7E3939%3BAH%3Acenter%3BBGC%3AFFFFFF%3BLBGC%3 AFF3333%3BALC%3AE9382F%3BLC%3AE9382F%3BT%3A000000% 3BGFNT%3A7E3939%3BGIMP%3A7E3939%3BFORID%3A1%3B&hl=en

Yes, I did. Although I didn't try it with a different xserver. I don't know if that might be worth a try?

I've also found some downloads at http://www.chzsoft.com.ar/855patch.html which are worth looking at.

the only way for me to get X in knoppix is to specify screen=1280x1024 (you may choose another resolution) and use vga=normal. The i810 really doesn't like framebuffering so everything in virtual terminals is huge :(
And so my complete bootstring concists of: knoppix26 lang=us screen=1280x1024 vga=normal

In the end, I didn't need any of the patches. The issue was solved by setting the refresh rates correctly. The relevant cheatcode was:

vsync=100.0

Thanks.
