[Solved] make/help me to make a xorg.conf from xrandr

Hi all,

I have following command lines (i use for setup dual-head and it's in .xinitrc that's called by slim):

xrandr --output DVI-0 --mode 1280x1024
xrandr --output VGA-0 --mode 1366x768
xrandr --output VGA-0 --left-of DVI-0

It's setup a dual-head configuration, i can move windows of one monitor to other, use browser in one while watch movie in other, etc...

but i want to do this on xorg.conf, why ?
* I use awesome (work perfect), MATE (working, but setting in mate-control-center, not in .xinitrc), GNOME (problem, problem, and more problem, if i set in gnome-control-center, i'll explain more about this)
* I want to it be system-wide, and Display Manager independent.

More about setting in gnome-control-center:
VGA-0: 1024x768 DVI-0: 1024x768 (so working)
VGA-0: 1366x768 DVI-0: 2048x1024 (terrible, impossible to use, stained yellow)

Then, someone can make or help me to make a xorg.conf ?

PS: i've tried already made by myself, but no success

If you really need help, gives us a bit more to work with than 'no success' (what did you do? what is the (unsatisfactory) result?).

Re: [Solved] make/help me to make a xorg.conf from xrandr

also xorg.conf is deprecated. Monitor settings usually go into 10-monitor.conf

I've tried this: http://pastebin.com/c0q8GMyh
and other modes (using two Device sections, or using xinerama), the 'no success' mean X start with VGA-0 in 1024x768 mode (no 1366x768 avaliable), and screens are mirrored.

Re: [Solved] make/help me to make a xorg.conf from xrandr

For awesome, I just have a key command coded into my rc.lua for when I have an external monitor setup.  You could store the command in rc.lua so that you don't have to type it everytime.  Of course, you can do this for just about any WM/DE. 
It seems that VGA-0 and DVI-0 are on the same card, but having it on different cards, doesn't want to cooperate quite so well.
I also have the keycode set so that I can switch the order the monitors are in relation to each other.

nomorewindows

Re: [Solved] make/help me to make a xorg.conf from xrandr

You can put that all on one line.
xrandr --output VGA-0 --mode 1366x768 --output DVI-0 --mode 1280x1024 --right-of/--left-of VGA-0/DVI-0
And in your xorg.conf line, you just tell one monitor to be to the left/right of the other one.  Or I forget which section of xorg.conf it is, but you actually put option left-of/right-of VGA-0/DVI-0

I don't know about those radeons, they work dual monitor in Windows just fine, but to do it in Linux, it doesn't want to do it for some reason.  All the graphics are corrupted and such.

Re: [Solved] make/help me to make a xorg.conf from xrandr

I modified my xorg.conf, now i get two monitors working, like i want, except for one thing resolution of VGA-0, VGA-0 alway start in 1024x768, but DVI-0 is correct 2048x1024.

% xrandr                   
Screen 0: minimum 320 x 200, current 2304 x 1024, maximum 4096 x 4096
VGA-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
   1024x768       75.1*    72.0     70.1  
   832x624        74.6  
DVI-0 connected 1280x1024+1024+0 (normal left inverted right x axis y axis) 376mm x 301mm
   1280x1024      60.0*+   75.0  
   1280x960       60.0  
   1152x864       75.0  
   1024x768       75.1     70.1  
   832x624        74.6  
S-video disconnected (normal left inverted right x axis y axis)

There is no difference if you put the stuff into xorg.conf or 10-monitor.conf. xorg.conf is not deprecated, it was specifically part of the design when they were implementing split config files. It's the equivalent of 99-something.conf in that it is read last.

Also, I consider putting xrandr commands into .xinitrc a hack, xorg.conf (or equivalent in xorg.conf.d/) being a proper solution.

@hotvic: What Raynman linked to is 100% correct, you need two simple Monitor sections and that's it.

My point was that using the simple proper solution, instead of that crazy file you have now, might fix your problem.
