I finally decided to get my woody machine at home to use the X4.0.3 nv driver instead of the xserver-svga from 3.3.6 it had been using.
After some struggling with apt-get and dpkg, I finally decided to uninstall all X-related packages and start over. This worked fine except that now colors are screwed up when I run mozilla or netscape. Basically, blues are rendered as aqua/green and netscape, at one point, complained about not being able to "allocate pixmap for default background." Up until now mozilla/netscape are the only apps that have given me trouble. Is there a package I'm still missing? Or maybe my XF86Config-4 file's missing something? Any ideas? TIA
