I run arch Linux on an hp laptop. I installed a graphical login manager (gdm) and during boot, the kernel unpacks, systemd starts, but when it attempts to start my login manager
"An error has occurred :(. Log out and try again.
[Log out]"
But I can't select that button. I know that uninstalling it will repair my system, or at the very least, stop the bleeding. I need to be able to boot into a thumb drive, access my installation and sudo pacman --remove gdm
BUT, I am not sure the exact procedure to do so without messing up my system. What partitions do I mount, do I need sudo, do I need to tamper with any init scripts? The laptop is fairly junk, and nothing important is on it, but I don't want to reinstall for a misconfigured package.
EDIT: Ok, I have found that with the arch-chroot scripts, I can get into an install by mounting all partitions mount /mnt /dev/sda1 /dev/sda6 ; arch-chroot (something, I think the drives I mounted(This is most of the part I need help with))
archiso@joeyhobbypcarch / # su averagejoey2000
averagejoey2000@joeyhobbypcarch / $ sudo pacman -R gdm fprintd ; yaourt -R (package 1 2 3)
Is any part of this wrong? I know the partition table by heart, I can find the buggy package within minutes of controlling the device.
EDIT: Added caveats! Screen is mostly busted. How quickly can I have it output to an external monitor? I don't have an arch iso handy. Can I chroot from an unrelated live os; say "T.A.I.L.S."?
