LEAP 42.2 with AMD Redwood with three ports?

[martinprowe]

Hi,

As the title says, I have three ports on my AMD HD 5xxx card. A monitor each on the DVI-0 & VGA-0 ports and a home theater amplifier (audio only) on the HDMI-0 port.

My problem, is that I can’t stop the settings “dancing” around as I turn on/off the monitors and more importantly the HDMI sinks.
Where & how can I set up the displays as I would like and then “freeze” it so that when I turn on the HDMI audio, I don’t loose the displays?

Regards, Martin

What desktop are you using? if you’re using kde/Plasma, then try it with kscreen … though, when settings keep changing, its sometimes indicative of the kscreen cache needing to be cleared out (as its interfering with configuration reality)

you can also use xrandr to set your config … put it (the xrandr command for the config that you want) into a script and place that in any one of a number of spots that will suffice for the job (e.g. autostart)

Hi Tyler(?),

Thank you for the tips…

@Tyler_K

What desktop are you using?

Yes, I’m using KDE/Plasma. And yes, I have been using kscreen

you can also use xrandr to set your config

And yes again, I have tried that. This is my script in autostart:

#!/bin/sh
xrandr --output DVI-0 --primary --mode 1920x1080 --pos 0x0 --rotate normal --output HDMI-0 --mode 1920x1080 --pos 0x0 --rotate normal --output VGA-0 --mode 1680x1050 --pos 1920x0 --rotate normal

You will note that as I have three desktops and only two displays, I have set the DVI and HDMI displays to overlap in the hope that the DVI display will be to the fore and active and the HDMI non-display will sit harmlessly to the rear! However, if I boot with the HDMI off and later turn it on, the third desktop pops up to the right of the other two!

One more specific question if I may? How do I map virtual desktops to graphic ports? For, example how can I know that Desktop 1 is the DVI display and Desktop 2 is the VGA display.
Right clicking and setting a a different wallpaper on each has limited success! Turn the HDMI off & on again, and I’m lost.

I do not know what you mean by three desktops and only two displays.

In any regard, lets back up

Your device is not an eyefinity card, so its only going to be able to use two of the outputs at any time. Pick your poison (so to speak).

You don’t. That’s not what Virtual Desktop’s are about.
