So I’ve been looking around on the web for some while now but this seems to be a tricky task.
I intended to change my default terminal on a Mint system from gnome to alacrity.
I had alacrity installed before on the same system and it seemed to be work fine.
I have not set up my root user or know the password for it so this makes this extra hard!
To change the default global behavior (e.g. pressing Crtl+Alt+T) modifying the
/etc/passwd seemed reasonably to me.
This is what the last line looks now:
But: If I want to open a shell now almost a thousand instances do appear once the command is triggered and after a short while the whole system crashes.
I don’t know how to reset to the default setting since I need a shell and that tool is broken…
Here is what I tried so far
- Try to use the shell env available at user log in: Login ends in an infinite loop
- Try to open the
/etc/passwdin graphical environment: Cannot modify the file (read only)
So here what I wish: Make this undone without reinstalling the operational system.
Thanks for your help and advice!
The field you are trying to change in /etc/passwd is used to set the per user shell (usually /bin/bash on Linux). The terminal emulator you want to use is can either be done with update-alternatives (system wise if you have root) on Debian based systems, or Window Manager specific configuration in general (GNOME, KDE, Xmonad etc).
Login in as root, and change the /etc/passwd file back to using a valid shell for the user in question. Not sure how you don’t have a root user. If you don’t have the root password then follow the normal password recovery process. Boot from a live or rescue cd. If it doesn’t mount the file system for you, mount it manually then edit /mnt/etc/password (where /mnt is where the original file system was mounted). Unmount and reboot your system normally.
