Allow to disable same image on all monitor by default [15$]

[alexarnaud]

Expected behaviour

I would like to be able same image on all monitor by default with a GSettings because for low-vision people screen magnification software don't support double screen on Linux so I need to disable.

Actual behaviour

With the current situation if a visual-impaired plug a new screen the screen magnifier will be automatically turned off so it means the people that cannot read the screen have to unchecked a boxes on the interface but it's impossible for them because the screen magnifier doesn't work.

MATE general version

1.20

Package version

1.20.1

Linux Distribution

Best of all possible behavior would be to sense that the screen reader is running and automatically disable clone output so long as the screen reader is being used.

Alternately it would work to set this as never being the default, since we now have the "same output in all monitors" check menu item in the xrandr applet popup menu. That allows laptop users setting up things like projectors to quickly set up clone no matter what the default, thus removing the need to have clone as a default.

@lukefromdc Detecting screen magnifier could be really difficult. I think we should avoid this and make the feature available for all.

@lukefromdc @raveit65 @vkareh Do you plan to work on this or should Hypra could contribute to this?

Best regards, Alex.

@alexarnaud, so let me see if I understand. You want a gsettings that a user can set to override what the default should be when a new monitor is plugged in? Effectively this would expose the randr "clone" option outside of the randr applet, right?

Right :), only for clone, I just expect to be able to disabled clone by default due to accessibility concern. If it's available from the GUI it would be great to make it available really for all, if it's only a GSettings it would be OK for me right now.

At the moment, I am not encountering "clone" as being the default if I start up a "test" user default session with my normal two monitors installed, but this is when Xorg having just been run with a side by side or single layout. If "clone" is still the default, this should probably be changed to side by side (xinerama layout) due to this accessability issue.

No new GUI option would be needed, and now we have one-touch application of "clone" in the xrandr applet. If screen readers can't read clone, a user accidently triggering it from the applet would not be able to confirm the change to clone, and the layout would automatically revert, avoiding the need for a fully sighted helper to fix things.

Clone as the default has another problem that I used to get all the time: limiting the resolution of a large primary screen to that of a smaller secondary every time a live USB stick of a distro is booted until the display capplet can be opened. Remember that the xrandr applet is not in the tray until selected from the display capplet.

@lukefromdc I totally agree with your last comment.

@raveit65 @vkareh @monsta @flexiondotorg @clefebvre What are your opinions ?

Is clone the default option?

On my Debian Stretch "9" box, yes. I'm running 1.16 GTK3 and as I see no way to change the default behavior other than inside the code itself it should be the default.

Sure we can change that. The clone mode is only useful for presentations which is a rare case with linux, imo.

[alexarnaud]

@raveit65 @vkareh Is it OK to let us (Hypra) submit a pull request ? We'd like to implement that before the end the month.

Best regards, Alex.

[vkareh]

@alexarnaud - of course!

[alexarnaud]

As @sthibaul as solved the issue in the screen magnifier part (Compiz/Ezoom) I'm closing the issue to avoid to change the default behavior and habits of users.

Best regards, Alex.
