Without xorg.conf, I have only one half of screen. I can enable 2 screens of same graphics card with xrandr of course (and kde system setting too)
But unfortunaly I can not use xrand to enable my 3rd screen connected on my second graphic cars DISPLAY=:1 /usr/bin/xrandr --output VGA-0 --mode 1280x1024 and DISPLAY=:1 xrandr --setprovideroutputsource "ATI Radeon 3000 Graphics @ pci:0000:01:05.0" return is: "Can't open display :1" (I tested with and without "xhost +" command previously) and xrandr --setprovideroutputsource 1 "ATI Radeon 3000 Graphics @ pci:0000:01:05.0" crash kde What do you mean by "Oops, the DISPLAY=:1 wasn't supposed to be there." ? ty Pascal -------------------------------------------- En date de : Ven 30.6.17, Michel Dänzer <[email protected]> a écrit : ... > If anyone could help me?

Then you can configure the outputs of both GPUs with xrandr or any graphical monitor configuration tool using the RandR extension. _______________________________________________ xorg-driver-ati mailing list [email protected] https://lists.x.org/mailman/listinfo/xorg-driver-ati
