Change to severity blocker, there is no known workaround and xorg/gdm don't work. I have a laptop(Compaq 1201EA) that had XP installed until today, running with no problem. As I'm using mainly Ubuntu 8.04 in my Desktop since it came out, and I'm enjoying it, so I decided to install it in the laptop too. I tried to install Ubuntu 8.04 with the x86 live CD, but found the laptop monitor will hang. Hoping in text mode the problem didn't exist, I downloaded the x86 alternate desktop CD to install in text mode, and installed Ubuntu without any problem. The fist time my computer was booting the newly installed Ubuntu installation, the same problem occurred. The monitor hangs while starting Ubuntu, and it doesn't react to Ctr+Alt+F1 or Ctr+Alt+Backspace To be able to start a session without gdm to crash I disable it, by booting in safe mode and: update-rc.d -f gdm remove after that I installed ssh server so I could login through my Desktop: sudo apt-get install openssh-server In my Desktop: ssh 192.168.1.2 sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade sudo apt-get install xresprobe sudo apt-get install discover1 sudo apt-get install xserver-xorg-core-dbg ( tried to find xserver-xorg-video-trident-dbg but didn't found any. ) sudo update-rc.d -f gdm remove sudo reboot sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_bak sudo nano /etc/X11/xorg.conf ----------------------- >Section "ServerFlags" > Option "NoTrapSignals" "true" >EndSection ----------------------- sudo gdb /usr/bin/Xorg (gdb) run -keeptty -dumbSched ----------------------- Starting program: /usr/bin/Xorg -keeptty -dumbSched [Thread debugging using libthread_db enabled] This is a pre-release version of the X server from The X.Org Foundation.

I think the original bug report here (NoDCC causes hang) has been fixed. I am currently testing the trident driver on an ancient laptop here, and it has many bugs, but this isn't one of them. The "vesa" mode doesn't work, and most importantly auto-detection doesn't work. Manually writing your own Xorg configuration and assigning driver as "trident" however, works fine.
What you need is:
Driver "trident"
Option "AccelMethod" "EXA"
At that point you get the proper response from Xorg:
(WW) TRIDENT(0): Option "NoDCC" is not used
So it simply skips NoDCC in the config file and in turn skips the hang.
I will be opening another bug report regarding detection.
