On my test laptop, I installed Athena 9.3 and configured X. The
installer's automated X configuration didn't work right for me, but I
just had to edit some lines in the "Monitor" and "Screen" sections to
make it work.
After the update to proto-Athena-9.4, however, my X configuration was
invalid. One of the InputDevice sections had /dev/psaux as the device
name, and that device no longer exists. Changing it to /dev/mouse0
works. (Under RHEL 3, /dev/mouse0 does not exist, though /dev/mouse
exists as a symlink to /dev/psaux.)
Worse, when X fails to start up for this reason, something seems to go
wrong resetting the video mode, and I wind up with a blank screen. A
mingetty is running on tty7, but nothing is visible, and I don't
believe keyboard input is being honored. I can ssh in, however, and
if I kill the mingetty, the system will retry running X and will
succeed if I've fixed the configuration file. This failure may be
hardware-dependent.
(In an SDIT meeting, I claimed that the XF86Config file would simply
disappear during an update to RHEL 4. This is not the case; it is
renamed to xorg.conf. I'm not sure how I got the wrong idea before.)
