Hello everyone, I have three monitors. Each connected with DVI cables to a Radeon HD 8830M. Two of them are connected with a DVI-DP adapter. The problem is that I can only enable two of the monitors simultaneously, otherwise I get this error message: "xrandr: Configure crtc 0 failed"
Both of the following work fine: "xrandr --output DisplayPort-3 --mode 1680x1050 --pos 1920x0 --rotate normal --output DisplayPort-4 --mode 1920x1200 --pos 0x0 --rotate normal --output HDMI-1-2 --off --output HDMI-1-1 --off --output DVI-0 --off --output DP-1-3 --off --output DP-1-2 --off --output DP-1-1 --off" and "xrandr --output DisplayPort-3 --off --output DisplayPort-4 --mode 1920x1200 --pos 1680x0 --rotate normal --output HDMI-1-2 --off --output HDMI-1-1 --off --output DVI-0 --mode 1680x1050 --pos 0x0 --rotate normal --output DP-1-3 --off --output DP-1-2 --off --output DP-1-1 --off" but when I try to enable three monitors in the following way: "xrandr --verbose --output DisplayPort-3 --mode 1680x1050 --pos 3600x0 --rotate normal --output DisplayPort-4 --mode 1920x1200 --pos 1680x0 --rotate normal --output HDMI-1-2 --off --output HDMI-1-1 --off --output DVI-0 --mode 1680x1050 --pos 0x0 --rotate normal --output DP-1-3 --off --output DP-1-2 --off --output DP-1-1 --off" I get the following error message: "$ bash .screenlayout/testi.sh screen 0: 5280x1200 1399x318 mm 95.85dpi crtc 0: 1680x1050 59.95 +3600+0 "DisplayPort-3" xrandr: Configure crtc 0 failed crtc 0: disable crtc 1: disable crtc 2: disable crtc 3: disable crtc 4: disable crtc 5: disable crtc 6: disable crtc 7: disable crtc 8: disable screen 0: revert crtc 0: revert crtc 1: revert crtc 2: revert crtc 3: revert crtc 4: revert crtc 5: revert crtc 6: revert crtc 7: revert crtc 8: revert" The outputs that are not in use in the scripts are outputs of the motherboard.
