After installing Xubuntu on the P1120, I created a new user and deleted the user created when I installed the OS.
Unfortunately, I didn’t know that I had to make the new user a member of the “admin†group for the user to be able to use “sudo†to do privileged actions. Somehow the user that I deleted wasn’t really deleted, but it’s no longer a member of the “admin†group either.
I can’t just reinstall the OS since I no longer have the second laptop for use with PXE booting and I haven’t been successful in creating floppies for the rather complicated floppy installation procedure. I’m left with trying to find a working Linux rescue floppy so I can modify just the one /etc/group file, but so far no luck.
