The xrandr source is a mess. I tried adding some debug prints in find_output and it seems that xrandr does not find the output but sets something somewhere anyway, even if --dryrun is specified. ~/x11-xserver-utils-7.4+2/xrandr/build $ ./xrandr --dryrun --output DVI-0 --primary find_output_by_name: DVI-0: find_output: (nil) find_output: (nil) find_output: DVI-0, 0, 0x00000000 find_output: (nil) find_output_by_xid: 0x0000004d: find_output: DVI-0, 0, 0x0000004d find_output_by_xid: 0x0000004d: find_output: DVI-0, 0, 0x0000004d find_output_by_xid: 0x0000004c: find_output: VGA-0, 0, 0x0000004c crtc 0: 1280x1024 60.0 +0+0 "DVI-0" ~/x11-xserver-utils-7.4+2/xrandr/build $ ./xrandr --dryrun --output DVI --primary find_output_by_name: DVI: find_output: (nil) find_output: (nil) find_output: (nil) find_output: (nil) find_output_by_xid: 0x0000004d: find_output: DVI-0, 1, 0x0000004d find_output_by_xid: 0x0000004c: find_output: VGA-0, 0, 0x0000004c -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
