Reset Kudzu to re-detect monitor


I have a weird situation. I'm building a homebrew PVR using mythTV, based on FC3.
I got everything working 100% when hooked up to my computer monitor. However the end goal is to move it to the stereo / TV. I have a XGA/Elite VGA -> S-Video device instead of a TV-out card. I know this works because I had it working with FC2 prior to my full switch to FC3.

I was stupid and when I moved the machine over to the TV, and didn't take the keyboard with me (I have my remote control setup for input). When I plugged in the XGA device and turned on the machine, kudzu came up saying that it detected the new device and to press any key to configure it. Well, since the keyboard wasn't hooked up, I didn't get to "press any key" before the timer ran out. Problem is now that what ever it did, my refresh rates or resolution are so messed up, I can't use X on my machine (the other terminals work fine). Any subsequent reboots, the device is no longer a "new" device and thus I don't get the opportunity to configure it.

So my question is:
1. How do I reset the hw detection stuff to remove the profile for this device so that on the next reboot, the OS thinks it is a new device and should allow me to configure it.

As root, you shold be able to run the command:


to reset your video.

Your situation is not "standard" but this may work for you. If not, you could always reconnect your monitor, allow kudzu to redetect and configure that, then hook your current configuration back up making sure that you do have a keyboard available.

Try looking at the /etc/sysconfig/hwconf file. Maybe you need to find your hardware item in the list and change the 'Detached' attribute to 0. Or perhaps delete its entry and reboot.
