I have a C400 and have had problems in the past, seemingly because there are some known problems with the i830 graphic chip.
I found an article discussing known problems with it at

http://www.cse.unsw.edu.au/~chak/linux/c400.html#xfree86

Can someone with a better knowledge than me have a look at that and give me some hint ?

Thanks

[with previous version, X would start but with 800x600 resolution, and i never could get anything more than that with slitaz, though i use 1024x768 with windows and other distros eg ubuntu -- i was hoping to be able to use the vesa mode 773 as described in the referred article, stable V3 was allowing to enter this but this cooking does not).
from what i understant, the chipset uses 1MB of ram by default and "sometthing" has to be done to allocated 12 MB of memory at startup so that the appropriate resolution can be reached.
