I already have one instance of Archlinux installed that has xorg, and KDE installed, and from looking at /var/cache/pacman/pkg, I also have gdm installed. Now this instance of Archlinux works fine, and I can login to KDE with no problems. The graphics driver is trident, and according to /etc/X11/xorg.conf, that is the one that is being used. I now have installed another instance of Archlinux (Don't Panic) on a new machine that I've built. Mobo is Asus M2N-X Plus, and has no onboard graphics card, so I installed one with an ati chipset . Booting into Archlinux is ok, and I did a pacman -S xorg, and after that, a startx started the xserver with no problems, apart from the usual crappy display. I then did a pacman -S kde, and a whole bunch of kde stuff was installed, but a reboot, and changing to runlevel 5 just brought me back to the text (runlevel3) login. Looking at my earlier install of Don't Panic, I see that I'd also installed the gdm package, so I installed it on my new install of Don't Panic. Doing a reboot after this, there is no change, and booting up, and appending the kernel line to 5 has no effect, and I still find myself in runlevel 3. Is there some file that I need to edit, in order to use gdm as the display manager? Nigel.
