48145a91f9 monitor-config-manager: Let CRTC assignment transform be logical
This means that it doesn't necessarily mean what transform / rotation
the hardware resource gets, e.g. it instead represents the logical
transform related to the configured mode. This allows us to postpone
checking the plane capabilities until later (as rotation capabilities
depends is a plane property), when a plane has been assigned.

This was in practice already handled when configuring the
transform-via-offscreen case, handled when creating the view, and the
mode setting configuration.

429e65b993 monitor-config-manager: Allow backends to assign extra data
When we're configuring monitors, allow backends to add backend specific
assignments during resource assignment (mapping connectors and CRTCs
etc).

This will later allow the native backend's KMS monitor resources to
assign a primary plane and optionally a cursor plane during
configuration. This will then dictate what plane will be used for
primary plane updates, as well as cursor updates, until reconfigured
again.

3dca01a06c monitor-config-manager: Use scale from past configs when generating
When we e.g. generate switch configs (i.e. the ones from pressing the
Super+P or the switch-config key on laptops), try a bit harder to find a
"good" monitor scale.

With "good", it means pick a scale that was used in a previous
configuration. In practice, this means that if you for example have
configured your external monitor to use a specific scale, then pressed
e.g. "built in only", and then switched back to e.g. "external only" or
"linear", the generated configuration will use the scale that was
previously configured.

4580bca664 monitor: Add mode spec helper checking resolution similarness
If two modes are roughly the same, they should probably use the same UI
scaling factor. I.e. for the same monitor, if a 4K mode was configured to
have a certain scaling factor, and we generate a new configuration with
a similar sized 4K mode, we should re-use the scale previously
configured; however if we e.g. go from a 4K mode to a FHD mode, we
shouldn't.

This allows implementing better hueristics when using the switch-config
feature, where we'd be less likely to loose the for a certain monitor
mode combination previously configured scaling factor.

c326313370 monitor-config-manager: Find builtin configuration even when inactive
When creating the configuration for the builtin monitor we try to get
the panel configuration for the builtin panel, but we don't proceed if
that monitor is currently inactive.

This is fine when adjusting an active configuration to the current
device rotation, but it isn't correct when we want to create a new
configuration based on another where the monitor is configured but not
yet enabled.

So, only find the panel configuration without looking the current state
but ensuring that the passed configuration will enable it.

f803c0ee0a monitor-manager: Add config relationships and use it for orientation events
When we get an orientation event we don't care about keeping track of the
configuration changes, but actually we can consider the new configuration
just a variant of the previous one, adapted to floating device hardware
events, so we only want to apply it if possible, but we don't want to keep
a record of it for reverting capabilities.

Doing that would in fact, break the ability of reverting back to an actual
temporary or persistent configuration.
For example when device orientation events happen while we're waiting for
an user resolution change confirmation, we would save our new rotated
configuration in the history, making then impossible to revert back to
the original persistent one.

So in such case, don't keep track of those configurations in the history,
but only keep track of the last one as current, checking whether the
new current is child or sibling of the previously one.

d773aaf7a9 monitor-manager: Apply built-in monitor orientation to previous configurations
When we reuse a monitor configuration (from the storage or previously
used), we need to make sure that the built-in monitor rotation matches
with the current sensors status.

So, instead of trying to apply a previously used or stored configuration
with a wrong orientation and fix it later, if orientation is managed by
sensor, try to create another configuration based on the previous one that
uses the current built-in monitor orientation and use it.

the sensors orientation even if this is currently not used (for example
when an accelerator is available, but there's no touch screen).

This would cause to have a different behavior when configuration is

f6db6cd203 monitor-config-manager: Handle multiple builtin panels gracefully
While multiple built-in panels isn't actually supported in any
meaningful manner, if we would ever end up with such a situation, e.g.
due to kernel bugs[0], we shouldn't crash when trying to set an
'external only' without any external monitors.

While we could handle this with more degraded functionality (e.g. don't
support the 'switch' method of monitor configuration at all), handle it
by simply not trying to switch to external-only when there are no,
according to the kernel, external monitors available. This would e.g.
still allow betwene 'mirror-all', and 'linear' switches.

The crash itself was disguised as an arbitrary X11 BadValue error, due
to mutter trying to resize the root window to 0x0, as the monitor
configuration that was applied consisted of zero logical monitors, thus
was effectively empty.

bd6bab113b monitor-manager: Set switch config when create monitors config
It is linear config manager created when ensuring configuration.
However, the switch config is not set as LINEAR, but left as UNKNOWN.
This leads switch mode OSD always shows "Join Displays" icon, rather
than the next icon which is "External Only" after connect an external
display and press Super+P once at first time since mutter starts.

This patch moves switch config setting into
meta_monitor_config_manager_create_linear() (and the sibling functions)
to well prepare the monitors config and avoid missing settings.

e48516679c monitor-config-manager: Fallback to closed laptop lid configuration
When closing the lid of a laptop, we reconfigure all the monitors in order
to update the CRTCs and (if enabled) the global UI scaling factor.

To do this, we try first to reuse the current configuration for the usable
monitors, but if we have only monitor enabled and this one is on the laptop
lid we just end up creating a new configuration where the primary monitor is
the laptop one (as per find_primary_monitor() in MetaMonitorConfigManager),
but ignoring the user parameters.

In case the user selected a different resolution / scaling compared to the
default one, while the laptop lid is closed we might change the monitors
layout, causing applications to rescale or reposition.

To avoid this, when creating the monitors configuration from the current
current state, in case we have only one monitor available and that one is
the laptop panel, let's just reuse this configuration.

bcbb44fdea monitor-config-manager: honor accelerometer value changes when there is more than 1 monitor
Modify create_for_builtin_display_rotation to lookup the
MetaLogicalMonitorConfig for the panel in the logical_monitor_configs
list instead of only working when there is only 1 monitor.

The goal of this change is to honor accelerometer value changes when there is
more than 1 monitor.

Note, since create_for_builtin_display_rotation is also used for handling the
"rotate-monitor" hotkey and this commit modifies the common path of
create_for_builtin_display_rotation this means that we will now also honor
"rotate-monitor" hotkey keypresses when there is more than 1 monitor and
update the builtin display rotation instead of ignoring "rotate-monitor"
hotkey keypresses when there is more than 1 monitor. If this is deemed
undesirable this is easy to fix, but I believe that doing things this way
is more consistent.

When creating a new config because of a monitor being (un)plugged or

Before this commit we would always configure the internal panel with
a normal / upright transform when e.g. an external monitor gets plugged
in even if another transform was in use before plugging in the external
monitor. This is inconsistent and causes problems for several use-cases.
This commit fixes this by querying the accelerometer when creating a new

6267732bec monitor-manager: use MonitorsConfig to track switch_config
When constructing MetaMonitorsConfig objects, store which type
of switch_config they are for (or UNKNOWN if it is not such
type of config).

Stop unconditionally setting current_switch_config to UNKNOWN when
handling monitors changed events. Instead, set it to the switch_config
type stored in the MonitorsConfig in the codepath that updates logical
state. In addition to being called in the hotplug case along the same
code flow that generates monitors changed events, this is also called
in the coldplug case where a secondary monitor was connected before
mutter was started.

When creating the default linear display config, create it as a
switch_config so that internal state gets updated to represent
linear mode when this config is used.

The previous behaviour of unconditionally resetting current_switch_config
to UNKNOWN was breaking the internal state machine for display config
switching, causing misbehaviour in gnome-shell's switchMonitor UI when
using display switch hotkeys. The lack of internal tracking when the
displays are already in the default "Join Displays" linear mode was
then causing the first display switch hotkey press to do nothing
(it would attempt to select "Join Displays" mode, but that was already
active).

f12e6ad4f1 monitor-config-manager: Adjust accelerometer rotation for panel-orientation
The device orientation coming out of iio-sensor-proxy defines upright/normal
as the direction in which the picture is displayed on the LCD panel without
any rotation. This is necessary for accelerometer rotation to work properly
in desktop environments which are not aware of panel-orientation issues.

This means that we need to correct the logical-monitor-config / user-visible
rotation for the panel-orientation when we get rotation info from
iio-sensor-proxy.
