Using ~/.bashrc for the xhost command is not robust. It will only work if one of the Bash Startup Files for an interactive logon shell sources ~/.bashrc. It is common practice to do so but not universal.

If xhost is run unconditionally, it will result in an error when the user logs on at a virtual terminal: xhost: unable to open display “”. Making it conditional on $DISPLAY being set avoids this.

The same code will work for all users by using $LOGNAME instead of a hard-coded user name string.

Putting this all together, put this in ~/.bash_profile:

[[ $DISPLAY ]] && xhost +localhost:$LOGNAME

Hi, in reply to the latest pingback (comment #2; I’m not signed up to the forum it links to) — what exactly doesn’t work for you? Note that “mpromber” in this line

xhost local:mpromber > /dev/null

is my username, so you’d have to substitute your username.
