Description r087r70 2009-04-19 04:17:15 UTC
Created attachment 24937 [details] Xorg.0.log I have two monitors connected: tv lcd on the vga port and the primary monitor on the dvi port. The problem is that the primary monitor is assigned to the vga port and there's no way to change that, unless using "ignore" option, but that's not what I want. When X starts both the monitors are enabled, and it chooses a resolution valid to both. Then I have to exec the following line: xrandr --output VGA --off ; xrandr --output HDMI-1 --mode 1280x1024 --rate 75 to put the system in the right mode. From man xorg.conf: Option "Enable" "bool" This optional entry specifies whether the monitor should be turned on at startup. By default, the server will attempt to enable all connected monitors. my xorg.conf: Section "Monitor" Identifier "Monitor" Option "DPMS" "true" EndSection Section "Monitor" Identifier "Monitor" Option "DPMS" "true" Option "Enable" "false" EndSection Section "Device" Identifier "Device" Driver "intel" Option "Monitor-HDMI-1" "Monitor" Option "Monitor-VGA" "Monitor" EndSection I'm on an intel G45 chipset with debian sid.

Comment 3 MaLing 2009-04-21 18:53:05 UTC
yes, vga port is assigned by primary pipe A, DVI by pipe B, log file shows two monitors work correctly. Why do you ask pipe A to be assigned to DVI? thanks maling

(In reply to comment #3) > yes, vga port is assigned by primary pipe A, DVI by pipe B, > log file shows two monitors work correctly. that's the problem, they work despite i ask to disable the monitor attached to the vga port. the vga monitor is 1360x768 the dvi monitor is 1280x1024 the resolution that xorg chooses at startup is 1024x768, that is the highest resolution common to both screens. Instead I wish to disable the vga-connected monitor at startup, so that I can have the proper 1280x1024 resolution on the pipe B. The bug is that the whether i set Option "Enable" true or false doesn't change nothing. thanks rob

Please modify you xorg.conf as below, thanks. Section "Monitor" Identifier "Monitor" Option "DPMS" "true" Option "Disable" "true" EndSection

It works! So the xorg.conf man-page should be adjusted accordingly. Thank you, Rob.

I'm reopening this as this is a bug. The description is 'Setting "Option Enable false" in monitor section of xorg.conf doesn't work'. This is completely accurate. The man page clearly documents this. It mentions nothing about using "Disable true" instead of "Enable false". The last comment from almost 5 years ago is about the documentation being incorrect, and it is still incorrect.
