I've finally resolved my problem with `vim` working in "compatible mode". It was caused by _missing_ configuration files in /etc/vim I don't know why there were no files in /etc/vim - my Ubuntu installation is rather old. I've recorded my findings in bug #667235 to make default behavior of `vi` and `vim` not to be affected by shared configuration files. The bug also portrays another side of problem that `vi` (not `vim`) starts to run in "nocompatible mode" after `vim` is installed.
Vik, Samium, Peter, if the following fixes the problem with "nocompatible" mode in _vim_ for you, I'll mark this bug as duplucate of #667235 $ sudo aptitude purge vim vim-common vim-gnome vim-gui-common vim-runtime vim-tiny $ sudo aptitude install vim -- Using arrow keys in vim-tiny while in Insert mode introduces A,B,C,D into text https://bugs.launchpad.net/bugs/491615 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
