[solved]Gentoo Bash Prompt not working in X

lustikus · 2010-01-10 22:50:22

Hi

I'm using this .bashrc from AUR:
http://aur.archlinux.org/packages.php?ID=18418

it is said to be the standard bashrc from gentoo.

It works with xterm, but I now installed urxvt (256 color) and it doesn't work any more, my prompt ist not colored any more.

I'm not familiar with bash scripting, perhaps someone could have a look.
The Problem ist not my .Xdefaults, I tried with an empty one. I also did "source .bashrc".

after editing ~/.bashrc, did u run "bash" from the command prompt? (without " " )

if not try it! it may help

you must "source" the .bashrc again.

do something as

$ source ~/.bashrc

or simplier
$ . ~/.bashrc

thanks for the replys.

I ran "bash" and sourced the .bashrc again, nothing changes.
In a non-X console I see the colors, so perhaps it's urxvt related?

I just copy pasted the code in my bashrc and re-sourced it. It's working for me in urxvt. Can you post the contents of your bashrc? Please put it within code tags.

thanks for testing it.

This is my .bashrc. I did not change anything:

# /etc/bash/bashrc
#
# This file is sourced by all *interactive* bash shells on startup,
# including some apparently interactive shells such as scp and rcp
# that can't tolerate any output.  So make sure this doesn't display
# anything or bad things will happen !


# Test for an interactive shell.  There is no need to set anything
# past this point for scp and rcp, and it's important to refrain from
# outputting anything in those cases.

if [[ $- != *i* ]] ; then
    # Shell is non-interactive.  Be done now!
    return
fi

I also made a screenshot with xterm and urxvt in comparison:

Somehow your urxvt does not enable color, so the code falls back to

use_color=false

Which makes

if ${use_color} ; then

jump over to

else
    if [[ ${EUID} == 0 ]] ; then
        # show root@ when we don't have colors
        PS1='\u@\h \W \$ '
    else
        PS1='\u@\h \w \$ '
    fi
fi

which does not contain color.

Perhaps it is some urxvt setting that you should change so it presents itself als a color terminal instead of a black and white one.

Dirty fix would be to force it like this:
Try changing the use_colors variable to true.
That should make the first "if" statement enter the code contained in it, which is the colorful one.

thanks, your dirty fix works

If someone knows a less dirty fix, it'd be welcome as well

Anaways, I think I just use the PS1 String in this file and dump the rest, as I don't even know what it really does..

Might try specifying urxvt's color depth in .Xdefaults:

URxvt*depth: 32
