Hi, I wrote a while back about a problem where X apps used huge amounts of memory and I was just told that it was probably my fault somewhere, well, after switching the offending machine to Gentoo (I still use Debian on the other ones that work fine), I found I had the same problem. Turns out that I had to recompile fontconfig AFTER compiling XFree86 and installing it! I don't know exactly why that is, but if you're reading this (Branden) and want to know more, do a search on the gentoo.org bug list for something relating to fontconfig. This affected me with any new install of Debian (of which I did 4 or 5 after the first few weeks with the problem), so I think it is essential to be fixed in the binaries somehow. The affected system ran an NVidia video card (but this problem was both using the NVidia drivers and the nv drivers of XFree86). I hope this helps.
