Prevent Gnome apps autostart in KDE ( or vice versa)

If you are a user (like me) who runs both gnome and kde together and finds that some of the auto starting applications meant for either gnome only or kde only are running in both desktops , then /etc/xdg/autostart is the directory to look for.
In this directory we can see .desktop files of auto starting applications. For preventing an application from auto starting in KDE edit the applications .desktop file and add OnlyShowIn=GNOME;
For preventing a KDE application from running in Gnome add
OnlyShowIn=KDE; to that applications .desktop file and you are done

Kde 4.2.1 rocks

Hi guys kde folks have released kde 4.2.1
http://kde.org/announcements/announce-4.2.1.php
In one work amazing. The have fixed many annoying bugs i faced with 4.2.0.
One was performance issue with desktop effects enabled. Xorg was taking too much of cpu and my system was damn slow. Its better now with 4.2.1.
Now big changes happened in kopete. Yahoo messenger service was in a way broken in previous releases. Problems ranged from frequent disconnection to contact photos not being displayed at all.
And all have been fixed. Kudos to kopete team.

So any one using 4.2 must update to 4.2.1 it helps you to love kde even more.
