I found the cause. This is not USB/CD boot loader issue, but X server issue.
1. The problem can be reproduced in both CD boot and USB boot. 2. ID->ubuntu PASS->none does not work. what happened? 1. USB/CD boots. 2. forks gnome. 3. X crashes. 4. fall back to login screen. 5. enter ID/PASS. 6. forks gnome. 7. X crashes...... Booting Ubuntu with xforcevesa works. So, this is not boot loader issue, but X server issue. --- Okajima, Jun.
