How to disable monitor auto configuration?
Im running Ubuntu 16.04 (dev branch), XFCE as desktop environment.
My computer is connected to two monitors. One via regular VGA cable and the other
is connected to a HDMI Switcher. That setup works fine, but every time I temporarily change the HDMI Switcher to another HDMI connection Xorg detects that the monitor has been disconnected and reconfigures Xorg to only use a single monitor, switching the HDMI Switcher back to my computer doesn't reactivate dual monitor use either, I have to manually trigger that with xrandr
How can I prevent this kind of automatic monitor detection and reconfiguration from happening? I'd like to be able to switch the HDMI Switcher without the computer doing anything.
Command used to restore the multi-monitor setup:
xrandr
--output HDMI-1
--mode "1920x1080"
--panning "1920x1080+1280+0/0x0+0+0"
--output DVI-1-I
--mode "1280x1024"
--panning "1280x1024/0x0+0+0"

Some more things I tried:
With the monitor connected find out the modeline:
$ xvidtune -show
"1920x1080" 148.50 1920 2008 2052 2200 1080 1084 1089 1125 -hsync +vsync
Then with the monitor disconnected:
$ xrandr --newmode "1920x1080-new" 148.50 1920 2008 2052 2200 1080 1084 1089 1125 -hsync +vsync
$ xrandr --addmode HDMI-1 1920x1080-new
$ xrandr --output HDMI-1 --mode 1920x1080-new
This allows me to activate the display when disconnected, which would otherwise fail due to non-existent mode 1920x1080. The problem however remains, if I switch the HDMI Switcher the display gets disabled, even if I have it set to a custom mode.
This are the udev events when disconnecting the display with the HDMI Switcher:
$ udevadm monitor --property
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing

I assume the monitor is listed inxrandrwhen reconnected? Could you post the output ofxrandrwhen the setup is as you like it to be? we can then easily make it restore automatically on reconnect. Also, what is yourxrandrcommand to "manually trigger".

Updated the post. However I don't want to just automatically restore the config, I want it to not get messed up in the first place.

That is most likely out of reach, unless you find a graphics driver that fixes it. The issue is caused by the fact that the communication between the driver and your screen fails on connection, jumping to defaults. You need some kind of action, either by a shortcut key or automaitcally. Make your pick, fix it dirty or not at all :)

@Grumbel, Could you add the output ofsudo lshw -c displayto the question. If you have nvidia, try the answer in askubuntu.com/q/858798/26246

Then with the monitor disconnected:
$ xrandr --newmode "1920x1080-new" 148.50 1920 2008 2052 2200 1080 1084 1089 1125 -hsync +vsync
$ xrandr --addmode HDMI-1 1920x1080-new
$ xrandr --output HDMI-1 --mode 1920x1080-new
This allows me to activate the display when disconnected, which would otherwise fail due to non-existent mode 1920x1080. The problem however remains, if I switch the HDMI Switcher the display gets disabled, even if I have it set to a custom mode.
This are the udev events when disconnecting the display with the HDMI Switcher:
$ udevadm monitor --property
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing

Im running Ubuntu 16.04 (dev branch), XFCE as desktop environment.
My computer is connected to two monitors. One via regular VGA cable and the other
is connected to a HDMI Switcher. That setup works fine, but every time I temporarily change the HDMI Switcher to another HDMI connection Xorg detects that the monitor has been disconnected and reconfigures Xorg to only use a single monitor, switching the HDMI Switcher back to my computer doesn't reactivate dual monitor use either, I have to manually trigger that with xrandr
How can I prevent this kind of automatic monitor detection and reconfiguration from happening? I'd like to be able to switch the HDMI Switcher without the computer doing anything.
Command used to restore the multi-monitor setup:
xrandr
--output HDMI-1
--mode "1920x1080"
--panning "1920x1080+1280+0/0x0+0+0"
--output DVI-1-I
--mode "1280x1024"
--panning "1280x1024/0x0+0+0"
xrandr output on regular use:
Screen 0: minimum 320 x 200, current 3200 x 1080, maximum 8192 x 8192

I assume the monitor is listed inxrandrwhen reconnected? Could you post the output ofxrandrwhen the setup is as you like it to be? we can then easily make it restore automatically on reconnect. Also, what is yourxrandrcommand to "manually trigger".

Updated the post. However I don't want to just automatically restore the config, I want it to not get messed up in the first place.

That is most likely out of reach, unless you find a graphics driver that fixes it. The issue is caused by the fact that the communication between the driver and your screen fails on connection, jumping to defaults. You need some kind of action, either by a shortcut key or automaitcally. Make your pick, fix it dirty or not at all :)

This is not a final answer, just a pointer into the right direction. On XFCE the xfsettingsd programm is responsible for handling of the RRScreenChangeNotify event and triggering the mode switch, the exact function can be found in xfce4-settings-4.12.0/xfsettingsd/displays.c line 77, the function is called xfce_displays_helper_screen_on_event. Disabling the function will make the mode no longer change when a new monitor connects.
Debug information can be obtained with:
DISPLAY=:0 XFSETTINGSD_DEBUG=512 xfsettingsd --replace --no-daemon

This is not a final answer, just a pointer into the right direction. On XFCE the xfsettingsd programm is responsible for handling of the RRScreenChangeNotify event and triggering the mode switch, the exact function can be found in xfce4-settings-4.12.0/xfsettingsd/displays.c line 77, the function is called xfce_displays_helper_screen_on_event. Disabling the function will make the mode no longer change when a new monitor connects.
Debug information can be obtained with:
DISPLAY=:0 XFSETTINGSD_DEBUG=512 xfsettingsd --replace --no-daemon

I assume the monitor is listed in
xrandrwhen reconnected? Could you post the output ofxrandrwhen the setup is as you like it to be? we can then easily make it restore automatically on reconnect. Also, what is yourxrandrcommand to "manually trigger".– Jacob Vlijm

Updated the post. However I don't want to just automatically restore the config, I want it to not get messed up in the first place.

That is most likely out of reach, unless you find a graphics driver that fixes it. The issue is caused by the fact that the communication between the driver and your screen fails on connection, jumping to defaults. You need some kind of action, either by a shortcut key or automaitcally. Make your pick, fix it dirty or not at all :)

@Grumbel, Could you add the output of
sudo lshw -c displayto the question. If you have nvidia, try the answer in askubuntu.com/q/858798/26246– user.dz
