Ie right after X launches and splash screen occurs. /usr/bin/X goes into infinate loop consuming 99% CPU. Verified by booting to single user, starting sshd, and letting boot.

I posted some infos about this bug here: https://bugs.freedesktop.org/show_bug.cgi?id=11617 But I was probably wrong about "xorg starts correctly" as it doesn't start and it behaves like Timo described (100% CPU). So I correct my previous statement and re-post my infos (as attachments seem corrupted in the other bug). Computer: Toshiba 1800-100 and Trident Ai1 (for more info see the attached X org log and dmesg). Not-working Distributions tested: - Ubuntu 7.10 - Xorg 7.2 - Debian unstable - Xorg 7.3 - Fedora 7 - Xorg 7.2 Working distros: - Debian 4.0 - Xorg 7.1 - a lot of other distros with Xorg <= 7.1 Other reports: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-trident/+bug/154069 http://ubuntuforums.org/showthread.php?t=587668 Workaround: Add Option "NoDDC" in the "Device" section of xorg.conf Bugs probably related (or duplicates): https://bugs.freedesktop.org/show_bug.cgi?id=3946 Working combinations of xorg.conf: driver trident + option noddc Not working combinations: driver trident without option noddc driver vesa + option noddc Going to attach some logs.

If I start the installation in graphical mode the screen turns blank and CPU fan goes at the maximum speed (indicating constant 100% CPU usage); while if I start in text mode everything goes well.

To my surprise X.Org X Server 1.5.3 seems to work flawlessly even without the "NoDDC" option. So this bug is probably due to a weird patch downstream. The xorg.conf is generated by X -configure, with no modifications.
