Hi everyone: I am trying to setup 2 monitors. The hardware is: AMD chipset, ATI video card screen 3 Vga monitor 20" ( 1600x900 ) screen 2 DVI-I to adapter to Vga monitor 14" ( 1024x768)
I can use display and rotation to the following setup: screen3 main monitor screen2 extended desktop
But i have 2 problems and question 1) every boot the screen are cloned and not extended. How i can do to store permanently the extended configuration?
2) when the screen are cloned i see well into screen 2, but when i switch to extended the screen 2 the color are degraded like old 16 ega. How fix it?
Best Regards Christian

Cloning is normal until TDE has a chance to rearrange the displays.
I tried several approaches but what works well for me is a single desktop where the monitors are laid out using R&R (Resize and Rotate). R&R is always running for me in the systray. If you don't have it running there try KDE Menu / / System / Screen Resize & Rotate to start it.

Could be a video RAM limitation in your video card or a million other things. Can't think of an easy solution - - just poke around looking for clues. Sorry.

Wow -- you've set up a hard task here, with monitors that agree on no dimension. How much memory does your vid card have?
Is there some sort of ATI configurator app, as there is with Nvidia? I have two identical monitors and couldn't get some of my preferred settings to stick until I used it in combination with R&R. If there is such an application, you probably want to give it a try. But given the disparity between monitors and what seems like a limitation of the vid card, it could be that you'll not get what you seek under any circumstance.
Would love to be proved wrong about this, though! -- dep

Three unequal monitors in TDE here - see attachment.
Took some fiddling at first but has been working fine for a long time now.

Impressive -- particularly the numbering, which puzzles me (though without effect, so an explanation is not necessary). Mine's set up as a single display comprising two monitors, with a resolution of 1920x2160. Frankly, I've never been able to get the KDE/TDE display configurator to do anything useful, though I haven't tried it for a few years and it may have improved.
Any tool is better than editing XF86Config by hand . . . which used to be the only way to do anything non-vanilla. -- dep

Please provide output from the following: xrandr --listproviders xrandr | egrep 'onnect|creen|*' | grep -v disconn | sort -r inxi -Gay
Before running the above commands, update inxi thus:
sudo inxi -U
If you don't, you'll probably get error message(s) from a or y switches. If the command is refused, either update by following the instructions on:
https://smxi.org/docs/inxi-installation.htm#inxi-manual-install
or use the instructions on that site that allow to override the distro's -U switch defeat via an /etc/inxi.conf file.
Note that I don't try to use any DE's screen configurator. Instead, I do it globally via xrandr script in /etc/X11/ somewhere, depending on distro. With output requested above, I can probably make such a script for you.
The colors problem might not be solvable. An old Radeon card might have bad RAM (I seen it quite a bit) or insufficient RAM for the total output space.

But may be it is better OP is getting this done in the TDE
So what I do is I go in tderandrtray and in the "Global" and Global I check both option "store for the session" and "enable next time on start up"
On some intel chips it was necessary to add xorg.conf to tune the server, but on the recent ones I use it works out of the box.

Hi Christian,
I had similar problems on Intel IGP's. Switching with xrand results in a colormap error on the second screen. One possibility is to set the resolutions in administrator mode as default profile. But as this leads to other problems, if you login on different machines wit the same account or if you use openGL.... So now I setup the display geometry in a xorg.conf.d file. The attached sample is located in the folder /etc/X11/xorg.conf.d folder. For AMD graphic, you will have to change the driver name in the Device Section and you have to find out the names of your graphics ports for this driver. With the file, you can setup the placement of the monitors 'Option "LeftOf" "Primary Monitor" ' and if the automatic selection of the resolution fails, you can set the wanted resolution with 'Option "PreferredMode" "1920x1200" '.
