Description Tom Jaeger 2010-08-16 20:27:59 UTC 
When changing the "Mouse Orientation" to "Left-handed" in the gnome-mouse-properties configuration dialog, all slave devices will get their button map changed to "3 2 1 ...".  While this definitely the correct thing to do for physical devices, it leads to programs that send out XTest requests not working correctly:  If the program intends for a left click (button 1) to be emulated, this will get translated to a right-click.

Gnome should test for the XI_PROP_XTEST_DEVICE property (defined in
<xorg/xserver-properties.h>) and not change the button map if the property is defined.

I've only tested this on 2.30.2, apologies if the issue is fixed in git.

Thank you

We can't use XI_PROP_XTEST_DEVICE, it's not exported, instead we'll just check for the device name.

    mouse: Don't switch mouse buttons for XTest devices
    
    Fixes fake events generated by applications being the wrong button.
