I have the same problem with an ECS motherboard that uses the Nvidia chipset, with an Athlon X2 CPU. The mouse cursor disappears after the first logout when using dtlogin. I just switched to gdm. After a reboot, the cursor reappeared, and does not disappear when logging out from gdm. So, something in the dtlogin logout causes the problem.
Using Nevada b54, I had trouble getting gdm to run. To fix it, I had to change `default' to `gnome' in ~/.dmrc . This is not a good solution for multiple users. Without that change, the ~/.xsession-errors file records: /etc/X11/gdm/PreSession/Default: Registering your session with wtmp and utmp /etc/X11/gdm/PreSession/Default: running: /usr/openwin/bin/sessreg -a -w /var/log/wtmp -u /var/run/utmp -x "/var/lib/gdm/:0.Xservers" -h "" -l ":0" "mills" /etc/X11/gdm/Xsession: Beginning session setup... /etc/X11/gdm/Xsession: Cannot find Xclients /etc/X11/gdm/Xsession: Setup done, will execute: xsm /etc/X11/gdm/Xsession[273]: xsm: not found and the session terminates immediately.
