Bug ID: 427677
Summary: Feature Req: allow setting window position relative to
specific screen
Product: kwin
Version: unspecified
Platform: unspecified
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: rules

SUMMARY
We can already set window rules for the (absolute) position of a window in the
whole X screen, we can also set a specific screen a window should be on. What
we cannot (yet) do is set a specific position on a specific screen for a
window. This is useful on setups with a varying monitor configuration, e.g.
laptops that sometimes have a external monitor plugged in. If this external
monitor is set to be left of or above the internal monitor, the physical
position of the upper left corner (0,0) of the X screen will be changed, and
therefore the windows with position rules will be put into a different position
than if the external monitor were not connected.
What I suggest is adding e.g. a drop down menu to the 'Position' rule, where
the user can select e.g, the following options:
- Absolute (which is the current behaviour)
- Monitor/Screen 0 (e.g. if the position is set to 960,0 the window will be
halfway the first monitor if it is Full HD)
- Monitor/Screen 1
- etc ...
I imagine that in the background this would work by determining first the
position of the monitor the window should be on, and then adding on top of this
the user specified (relative) position which would give the (absolute) position
the window should be at.
E.g. I want window foo to be on screen 2 (the third monitor) which is at
position 3520x0, I want the window to be 200 pixels from the left side of the
monitor. Now I would have to set the position of the window to 3720x0, and it
will only work in this specific monitor configuration. What I suggest is
allowing the user to set the position to '200x0 on screen 2' instead. In the
background the absolute position would be calculated by getting the position of
screen 2 (3520x0) and adding the user specified position (200x0) to get
(3720x0) which would then be where the window will be positioned. The advantage
of this is that this will still work as intended if the position of screen 2 is
changed.
