Hi
Every time I choose another key combination in launchy I get this:
The hotkey you have chosen is already in use. Please select another from Launchy's preferences.
I am using PCLinuxOS 2010 with Gnome desktop.
And if I start launchy from a terminal I get this:
[ole@localhost ~]$ launchy
/usr/share/themes/Darklooks/gtk-2.0/gtkrc:181: Invalid symbolic color 'tooltip_bg_color'
/usr/share/themes/Darklooks/gtk-2.0/gtkrc:181: error: invalid identifier `tooltip_bg_color', expected valid identifier
failed to grab key

Since you are running the Gnome edition, you will probably get more responses at the PCLOS Gnome site:
http://linuxgator.org/forums/index.phpI did a quick search on the home page for "failed to grab key", but got only one hit, which doesn't seem to apply.
I use PCLOS e17 and PCLOS LXDE on different computers, but I get some weird gtk2 errors with some fairly generic programs. In your case, it looks like the error is being caused by an installed theme, Darklooks, that gtkrc is having issues with. gtkrc is a theme engine. There are 3 overriding configuration files for gtkrc-driven themes, but the only one you should be concerned with is:
/home/(your-username)/.gtkrc-2.0
The file is only a few lines, but I don't know enough about the configuration to make any recommendations. Mine looks like this:
# This file was written by PCLinuxOS
include "/usr/share/themes/Oxygen-Molecule/gtk-2.0/gtkrc"
style "user-font"
{
} widget_class "*" style "user-font"
gtk-theme-name="Oxygen-Molecule"
gtk-font-name="DejaVu Sans 10"EDIT: If you are using the Darklooks theme, try switching to another theme. Try one of the generic ones. If that doesn't work, then you might try this: see if you have a Darklooks theme installed, see if you can live without said theme, then see if deleting the theme solves the problem. If deleting or uninstalling the theme will uninstall additional packages, then STOP and DO NOT do it.
