Sounds pretty >significant to me. > How does XFree86 3.1 work on 2.0.5?... I use the S3 based version of XFree86 3.1.1 and it seems ok. Sometimes, XFree uses lots of memory and can cause paging. Try doing a ps -xla and see how big the VSZ and RSZ fields are... Also, there may have been some changes in algorithms in XFree -- I don't know about that. I am using XFree86 on a 486/66, with 20MB, and an F1280 (don't laugh) and it appears OK, but XFree does grow alot -- and there is work being done in the XFree group to fix that. This is a problem on Linux, and probably NetBSD also... John dyson@root.com
