Evolution freezes in "saving user interface"

Disable "Show the photograph of sender in the message preview"  in

Evolution Preferences -> Mail Preferences -> Headers

This is a workaround to solve the problem for now.

systray classic notification

gnome-shell extension Topicons (Shows legacy tray icons on top)
or in other words "systray classic notification"

Works on gnome-shell 3.6 and Fedora 18
https://extensions.gnome.org/extension/495/topicons/

Fedora 18 and SIS Driver

The SIS driver in Fedora 18 is broken, and the vesa driver is not an option, doesn't support more than 1024x768, and the X has a horrible rendering.

So, create the file /etc/X11/xorg.conf ant put this inside

 Section "Device"
        Identifier  "Videocard0"
        Driver      "sis"
        Option     "NoAccel"
EndSection

This will disable the acceleration from the graphic card, but at least the desktop is usable again, until this problem is solved.
