For some time, GTK apps running inside my KDE4 session would not pick up their theme
properly, making them look hideous in their default theme. I’m using a small wrapper
script (/usr/local/bin/startkde4) to get my KDE4 desktop up and running. Since I’ve put
the “unset GTK2*” line into the script, GTK apps pick their theme again:
#!/bin/sh export LD_LIBRARY_PATH=/home/kdedev/kde/lib export KDEDIR=/home/kdedev/kde export PATH=$KDEDIR/bin/:$PATH export KDEHOME=~/.kde4 unset GTK2_RC_FILES . /home/kdedev/kde/bin/startkde
If you’re still living under the “I use a GTK1 app” stone, put another line for GTK(1) apps
in there.
