[gentoo-user] X11 and HP2475w: First steps?

[meino.cramer]

Hi,

 before damaging "delicate electronic equipment" I want
 to ask, what the best way is to switch from a 1600x1200
 pixel analogous Iiyama monitor to an Flat panel HP2475w (LCD)
 with 1980x1200 pixel monitor?

 Graphics card is a (info via lspci):
 nVidia Corporation G73 [GeForce 7600 GT] (rev a2)

 With one analog and one digital output.

 Thank you very much for any help in advance!

 Keep hacking!

Hi,

I'm not sure if I understand your question correctly... Do you have 2
screens, and want to switch the output of your gfx-card from one screen
to the other? You could use both at the same time :)
Anyway - "xrandr" is your friend.
To see your adapters and modes run "xrandr" without options, then use
something like "xrandr --output VGA --off --output LCD --auto" (maybe
use "--mode 1920x1200" instead of "--auto". You have to experiment with
this...

Bye,
Daniel

If you're using binary nvidia driver I think it should autodetect your
monitor and everything should be fine... no need to specific modelines
or anything like that (however if you have done that with your old
monitor you may need to remove it). I switch between monitors often
and it Just Works(tm). :)

If you use framebuffer maybe you'll need to edit your grub config to
use a different mode, but LCD usually just scales invalid modes to fit
the screen anyway. I don't think you should worry about damaging it.

LCD monitors have to have the correct settings or they won't work. You
can damage them.

You probably have your system set up to detect your hardware just like
a LiveCD does.

True, I was only thinking about resolution but if he is manually
forcing sync rates then anything can happen. :)

Well like I said, if he is using nvidia-drivers he can leave the
configuration empty and it'll use the default mode which is
"nvidia-auto-select", which reads EDID from his new monitor and
configure everything properly without any trouble. Auto detecting
monitor capabilities is the default action unless you've specifically
told it to do otherwise.
