I had a problem with woody several days ago where X would die immediately after starting, before the window manager took over. In trying to fix it, I really messed up my X installation, so I decided to downgrade to potato and did a fresh installation of 2.2r2. I did this and everything was working fine (including X).
Since I had started with a somewhat minimal installation I just added a lot of new packages and now X dies immediately after starting with no messages, which is the same behaviour I had before with woody. System is a K6/2-350 with 128 MB, Cirrus 5430-based video card with 2048k videoram. Any ideas as to where I should be looking? Bob
