Matrox G450
HowTo Enable TVOut with a Matrox G450
This overview will cover how to get the TVOut working on a Matrox G450 using FC4 and MythTV .19. This covers my experience with this setup and how I got it to work.
For the most part, I followed Jarod's Guide on getting MythTV set up on Fedora Core. The initial setup was a little difficult in the GUI because whil the installer correctly identified my Matrox G450, the Matrox drivers that ship for x.org are for v. <= 6.8.1 while the installer uses 6.8.2. No biggie, I've set up FC before and was able to get by.
After the installation completed, I grabbed the updated Matrox drivers from [1]. Setting them up is easy - download, extract run install.sh to have the files copied to the correct place. A quick restart of X (ctrl+alt+backspace) gets everything nice and pretty.
After doing some reading in various places, I discovered that in order to get the framebuffer devices created so we can use them, we have to load the matrox modules at boot. We need to create /etc/sysconfig/modules/matrox.modules with the following code:
- !/bin/sh
/sbin/modprobe i2c-matroxfb /sbin/modprobe matroxfb_Ti3026 /sbin/modprobe matroxfb_crtc2 /sbin/modprobe matroxfb_maven
