Using the Ctrl key in config lines

begin
    prog = mythtv
    button = TV
    config = Ctrl+2
end

Repairing broken MythTV tables

2. cd /var/lib/mysql/mythconverg
3. myisamchk *.MYI
4. Identify broken tables
5. myisamchk -r brokenTable.MYI
6. Restart MythTV and MySQL

Slow mythfrontend menu transitions

This will often happen if (with an nVidia driver), the nVidia libglx file has been overwritten by an xserver upgrade. To check for this, run glxinfo | grep direct - if the driver is working the direct rendering should be on. If not, check the /var/log/Xorg.0.log for:

(EE) NVIDIA(0): Failed to initialize the GLX module...

In this case, it's possible to reinstall the latest nvidia linux driver, or alternatively, simply (as root):

mv /usr/X11R6/lib/modules/extensions/libglx.so /usr/X11R6/lib/modules/extensions/libglx.so.orig
ln -s /usr/X11R6/lib/modules/extensions/libglx.so.<nvidia ver> /usr/X11R6/lib/modules/extensions/libglx.so
