[SOLVED] Run pacman from external boot drive

There is something wrong with (I think) my GDM that causes my boot process to hang after "[OK] Started User Manager for UID 120". I cannot access other TTYs (no response at all to key presses). I'm thinking to chroot from an external boot drive (a USB drive with the Arch installation image), and uninstall/reinstall GDM for my original system. Is this the right way to go?

That should work, do the mounting and arch-chroot similar to the installation process.

Instead of using the installation media you can also try to boot to multi-user.target which should give you a console instead of a graphical login.

Thanks! I booted to multi-user.target and updated GDM, which solved the issue.
