Debian and DVI video?
|
|
|
| Generally speaking, do Debian and other Linux distributions work with video
boards that have DVI instead of the normal VGA ports? I have only seen Linux
hooked up to VGA, but who knows.

Sure, no problem. Even works on a very ancient system that still uses
XFree 4.3.
I don't know about dual-link DVI, though, in case you want to use a
30" display.

Yes, it works without a problem if you only have a monitor hooked up to the
DVI port. Strange things can happen if you hook up two monitors, though. On
nVidia cards, the VGA port is *always* assigned priority over the DVI port.
If there's a monitor hooked up to the VGA port, then it is automatically
the primary display.
This leads to some interesting scenarios:
1) If xorg isn't configured for multiple monitors (and odds are it isn't by
default in most distros), then you get a blank display on whatever is
attached to the DVI port.
2) If xorg *is* configured for multiple monitors, all login screens are
displayed on the monitor connected to the VGA adaptor. This could be the
exact opposite of what you want to see.
The latest versions of the nVidia drivers allow you to edit xorg.conf and
set the correct primary monitor in a dual-monitor scenario. I don't know if
this works if you want just a single monitor. But then, the official fix
would be to not plug anything into the VGA port.
I am running a Dell 2007FP connected to an eVGA nVidia 6600 via DVI with no
problems at all.

Interesting scenarios!
I run Linspire (you can see my level of Linux sophistication) and
wouldn't know how to install a new video driver.
Tks.

Never had any problem with DVI cables over the last couple years. On
docking stations or otherwise.

Sorry, the crux of my babbling there was: It will probably work. Try
plugging your monitor into the DVI port on your video controller and make
sure nothing is connected to the VGA port. Then restart X (there should be
an option to do so from the login menu).
It should Just Work.

Restart with Ctrl-Alt-Backspace. But be shore you have logged out
before. Data can get lost otherwise.

It does...

I have a nivida video card with DVI.
I replaced a similar card having vga with this one.
Didn't have to do a thing to make it work (except
for re-configuring my monitor to use the DVI connector
instead of the vga, monitor had both.
Just swapped the cable and it worked!
