[gentoo-user] Multiple Displays & nVida vs Radeon... take TWO

[gentoo-user] Multiple Displays & nVida vs Radeon... take TWO

[Justin Hart]

Hey folks,

I'm looking for a quick answer, because I may need to make a hardware
purchase tonight based on the replies.

I have a big presentation on Friday.  I noticed, the other day, that
upon hooking my laptop up to a projector, that the projector failed to
come on.

It is worth noting that I have had this configuration working before. 
I had made entries in xorg.conf that, should have, allowed for this to
work.  I figured that, because it was a different projector than I had
originally tested this setup on, that differences in the setup may be
the issue.  Tonight, I came back to my lab, plugged it into the
projector that I had originally set this matter up on, and it failed
to work on that projector.

Anyway, quick rundown.

I have a Dell Inspiron 9100.  In it is a Radeon 9700 mobile graphics
adapter, PCI express.

Any thoughts?  Do the nVidia cards do this better?

Welcome to the mess that are laptops and xorg/xfree with projectors.
Both nvidia and ati are as good as each other - and each have their own
little problems.  I currently use an ati M9

I find the main problem is most projectors I deal with work in a native
1024x768 mode, with higher modes internally mapped back to this
resolution.  I normally use 1600x1200 which works - mostly.  Things to
look for are jittery displays, missing edges, and no screen etc.  The
cure? - back the resolution down to something the projector is happy
with.  I find that "specs" saying a projector will do a particular high
resolution rather rubbery - the older the projector the less likely it
will be happy at a high res.

xrandr or one of the desktop applets can be used to change the
resolution on the fly.  if the projector doesn't come on, I go to
1024x768 and work up until we are both happy.

The main linux problem is getting a config that works at all!

Ok, well, another question.

I called Dell.  I asked "can I upgrade my Inspiron 9100 to take a
GeForce Go 6800."  The answer was no.

Three questions:

Is this because the GeForce Go is unavailable in AGP?
Is there another, suitable, graphics card that I could jump to?
Given that the board were available in AGP, is are notebook video
cards standard enough for me to even make the replacement, given that
a part could be found.

Laptop hardware is custom, so I doubt yu can replace anything with
something else.  

For radeons, use the xorg driver rather than the ati ones for a laptop.
You lose some, you gain some.  For me I can get it to work across
multiple projectors/monitor types and resolutions without rebooting (I
use suspend2) so I can just go into a lecture theatre, plug the cable in
and resume.  No picture, then just start changing resolutions until
happy (takes seconds at the most) Avoid autodetect - almost always chose
unsuitable resolutions with projectors, plus needed a cold boot (even
just shutting xorg didnt work - think its a bios thing) to work
properly.

Yep, however its also worth remembering to plug the laptop into the
projector and turn the projector on before booting the laptop. Often
they will auto detect what is connected to the port and adjust
themselves.

Ah.. Me too. 1400x1050. Missing edges at this res.

I used to solve this by putting different Res on LCD and Projector.

use Dual Monitor output in Xorg.conf.

1400x1050 in LCD
1024x768 in Output.

Best of both worlds.

I would be interested in a copy of your xorg.conf - its always good to
see how the other guy does it ...

Mine is at http://wdk.dyndns.org/xorg.conf.html

I actually got mine working pretty happily.  It connected to the
projector today and worked with no problems.
