Initial Summary:
Fubar X with Radeon AGP on Pentium III Coppermine

forum thread:

Just guessing that this is a kernel driver bug rather than an X bug, hence the
kernel component selected.

When the login manager tries to load, all that ultimately paints is the
background graphic. WINDOWMANAGER=/usr/bin/icewm startx produces a black screen
with mouse pointer. Xorg.0.log shows no apparent problem. No apparent
difference whether using kernel 5.9.10 or 5.8.15. Vttys work as expected.
Replacing the Radeon AGP rv250 ID: 1002:4c66 gfxcard with a Matrox G400 makes X
work entirely as expected.
