Out of curiosity, I plugged my T42p (2373-HTU) into a video projector
and noticed the following:
- it worked but the image was a bit fuzzy -- while I'm not 100%
certain, it appeared that my video card was driving the external
projector at a higher rate and it was forced to somehow down-
sample and it did not do a great job -- so perhaps adjusting
the rate or the resolution (my LCD is 1600x1200 native) would
give a crisper image on the LCD...?
- the external VGA adapter seems to be "always on" as Matthew
describes -- pressing Fn--F7 did nothing
- I'm running the very latest FC-4 stuff with *no* proprietary
drivers added (just as-shipped from Fedora + updates):
- kernel: 2.6.12-1.1447_FC4
- xorg-x11: 6.8.2-37.FC4.49.2
- lspci reports:
"01:00.0 VGA compatible controller: ATI Technologies Inc
M10 NT [FireGL Mobility T2] (rev 80)"
