Red Hat Bugzilla – Bug 6867
rxvt incorrectly(?) sets DISPLAY variable
Last modified: 2008-05-01 11:37:52 EDT
I'm not sure if this is a bug or just an annoyance, but at
rxvt sets the DISPLAY environment variable to unix:0.0
rather than just the local :0.0
It does this when no -display option is given to it.
I was using rxvt-2.6.1-1 from RedHat 6.1, and the same
problem seems to be present in rxvt-2.6.1-2 from Raw Hide.
Again, this may be some sort of intended behavior that just
seems odd to me, but I thought you should probably be
Thanks in advance,
unix:0.0 is a synonym for :0.0. Trust us.
It *is* a bug, in particular the behaviour is inconsistent with the man page.
Note that if DISPLAY is set to :0.1 when rxvt is invoked, the rxvt window
still appears on Screen 0; to get reasonable behaviour, you need to use
rxvt -d $DISPLAY
The annoyance I found, although I was incorrect to blame rxvt, *is* still in
existance. I suppose I could/should start a new bug, but if someone at redhat
is watching this...
Some (GTK) applications have trouble with the unix:0.0 DISPLAY variable. I get
"can't resolve hostname unix!" from a lot of GTK apps. The workaround was to
undefine the compile-time option from rxvt (or just use -d, or ...) and I
assumed it was just an rxvt problem.
Next time I have an opportunity to reproduce this I'll send specifics.
