you can disable load detection with xrandr: xrandr --output VGA-0 --set load_detection 0 Fabulous suggestion, too bad I can't actually do that because Xorg decides to NOT START AT ALL in the configuration I desire. Bit hard to run xrandr to runtime-reconfigure a non-running X server. If I have the display connected to the VGA port, everything works fine, but if it isn't (because the display is connected to another input via a hardware switch that provides no dummy load) load detection decides the output should just be disabled, period, and then the server dies because hey, it has no outputs.

Created attachment 17118 [details] HTPC Xorg config file for radeon Expected behaviour: VGA-0 always enabled when "Option Enable" is set. Observed behaviour: appears to do nothing. See attached config + logs, they ended up too large for the comment field. This is running on my HTPC, with a RV350 R9600 Mobility. In all circumstances that Xorg gets up and running, the other monitor can be successfully manipulated with xrandr. Dualhead isn't my goal, though, if anything I'm looking for a reliable way to force VGA-0 to be the only enabled output, and stay so whether or not the X server thinks it's electrically connected to anything. This is a laptop running with its lid closed as a HTPC with a CRT TV connected via RGB-SCART as its only output, an output which is frequently disconnected during startup via a physical switch. Load detection is at best highly undesirable. I have managed to disable it The Hard Way by patching it out of the driver, but obviously this is not ideal.
