Whoa Nelly! GF4-MultiScreen kills machine with X

[Matthew Carpenter]

Reading the README for the 3D driver from NVIDIA, I have figured out that there are two ways to configure X to utilize the TV-out from my new GF4Ti4200: MultiScreen, of CombinedScreen (TwinView).
After a little tinkering and decisionmaking, I got my machine working (apparently) correctly in a Multi-Screen setup.  It's sweet.  I have two desktops, one on my CRT and one on my TV.  But one gotcha has creeped into my "dream".  If I kill X (<CTRL><ALT><BkSpc>) it doesn't return....

For those of you wondering what the difference is, Multi-Screen mode uses X's ability to have two video-systems (look at the README if you have the NVIDIA driver).  Each video-system has it's own K Menu etc, mouse moves between screens but no apps can.
TwinView is a NVIDIA-specific feature which allows you to treat the second screen as simply an extension of your desktop.  You can move apps between them and X is basically unaware that you have two screens.  While this is appealing the video modes have to be identical: 1024x768 on both or 1280x1024 on both, etc...  I may try TwinView later, but I was interested in the clean mode and it works pretty well.

If you use NVidia's TV-out, be sure to read the README. It has more than its fair share of information!

Thanks,
Matt
