I have always had a problem with Evolution being installed when emerging gnome on my Gentoo system. Even with "-evo -eds" use flags, it still wanted Evolution.

Evolution is a BIG piece of CRAP, and I don't want it anywhere on my system. So I edited the gnome-base/gnome ebuild, and made all evolution stuff dependant on the "evo" or "eds" use flags, which worked fine.

However, I wanted to know why I can't have Gnome without Evolution, and I started asking around... Turns out that you can emerge gnome-light .... Sweet ;-)

I just installed a fresh WinXP virtual host on kvm on my Gentoo system. It didn't allow me to use the maximum resolution that my monitor supports (1440x900). So I started reading the kvm manual page, and found the --std-vga option. After restarting my WinXP machine with this option, Windows was unable to find a driver for the graphics card. Too bad ...

Recently I needed to run an application that needs X on a server running SLES10. Because it wasn't necessary to have the application output anything on a screen, the X virtual framebuffer was sufficient to accomplish this. You can easily install the X virtual framebuffer, which comes with the xvfb package in SLES10.
yast -i xorg-x11-Xvfb xorg-x11

Installing the xvfb package is sufficient to start the X virtual framebuffer server, but the application I needed to run also needed some fonts. So, I installed some extra packages as well with yast.
yast -i xorg-x11-fonts-100dpi xorg-x11-fonts-75dpi xorg-x11-fonts-scalable bitstream-vera fonts-config
