Have you tried the nv driver to see if the same thing happens with that?

This is correct functionality. Nvidia's own 'run' file blindly replaces the existing software opengl implementation. The Gentoo ebuild stops this occuring by placing the libraries in different locations and then using symlinks. That is what opengl-update is for. > (2) the Nvidia README says installation shd create files in > /dev , ie nvidia0 1 2 3 ctl , which weren't there with > either method of install'n. I can't check on this at the moment coz I'm still at work (for the last 26 hours) but I seem to remember a single nvidia0 entry in my /dev. > (3) /var/log/XFree86.0.log says "module(s) glx/nvidia > compiled for 4.0.2", whereas all the other modules loaded > were compiled for 4.3.0 . back with my usual working system > (software acceler'n), modules 'glx' & 'nv' are compiled for > 4.3.0 . the log does claim that "AGP 8x was successfully initialised". That is also correct behaviour. The modules are built for 4.0.2 for compatibility with older distributions (such as Debian stable ;-) but will work fine with XFree86 4.3.0 as well. > problem (1) seems to be with Gentoo's ebuilds; Nope > (2) mb with something like devfs, which i've never had to look into; Maybe > (3) may mean i need to compile the modules specially myself: Nope > i've never compiled a kernel or module explicitly (Nvidia's > 'run' compiled the interface this time), but i'm always > willing to learn to do new things.

Also try using the 'other' AGP driver. e.g. compile the kernel with agp as a module and add a line to your XF86Config to specify which driver to use. Jason -- [EMAIL PROTECTED] mailing list
