Re: Cannot project from laptop

Steps I take to get VGA-out working on my laptop:

- Boot computer, without projector plugged in
- Log in, etc
- Plug in projector, switch on
- In a terminal: "xrandr --output VGA-0 --auto"

You may need to replace "VGA-0" with something else: try the command "xrandr --prop" to list all your potential video outputs.

Re: Cannot project from laptop

Hi,
I've got a laptop with an ATI card.
Watched "man xrandr" and the --output and auto option.
It seems fine to me.
But i'd like to know if it will be a clone in the projector, and that clone will be set for the native resolution of the projector?

Right now, my resolution is set at 1280 800 on my laptop.
With this command, will it clone the desktop to the projector and set it to the good resolution ?
(I'm sorry, i can't test it at home...)

Also, is there another way to do it with some kind of GUI ?
(it's for my girlfriend and she is not comfortable with command line... yet)
Oh and I'm using the fglrx driver, installed via the restricted manager after starting kubuntu on that laptop.

Thx

Re: Cannot project from laptop

As far as I know there's no pretty GUI for this yet, the functionality has only been around a little while.

However - there is a nice easy way to do things...

You can create shortcuts on the desktop (Create New -> Link To Application) to run various xrandr commands. I did this recently when my laptop was used for an away weekend and even the most computer-illiterate people there had no problems in switching modes.

As for the resolution - not sure on that one. The "auto" option seems to clone by default; and you can change the resolution with --mode 1024x768 or whatever your projector supports.

Fiddle, see what happens

Re: Cannot project from laptop

Can you post your xorg.conf, and the output of "xrandr --verbose"?

Re: Cannot project from laptop

sorry i can't right now, since I don't have that pc here.

I can add I tried playing with aticonfig, with no luck (generated a dual head configuration etc...)

I'll "bump" this topic when I have all the informations avaible
I think I can make it work by "sudo vim /etc/X11/xorg.conf, but I don't want to do it since I want to prove that kubuntu is "user friendly", but my girlfriend doesn't think so.
So if it works without editing manually xorg.xonf, it will also contribute to the expansion of kubuntu !
Thx
