Usage
|
||||
-----
|
||||
|
||||
The client command is the binary file: **looking-glass-client**. This
|
||||
command should run after the Windows Host Application has started.
|
||||
|
||||
You may run the client directly from the build directory. Alternatively, to
|
||||
install the client for all users, you can run
|
||||
::
|
||||
|
||||
make install
|
||||
|
||||
To install for the local user only, run
|
||||
::
|
||||
|
||||
cmake -DCMAKE_INSTALL_PREFIX=~/.local .. && make install
|
||||
|
||||
.. _client_key_bindings:
|
||||
|
||||
Default Key Bindings
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
By default, Looking Glass uses the :kbd:`Scroll Lock` key as the escape key
|
||||
for commands, as well as the input :kbd:`capture` mode toggle; this can be
|
||||
changed using the ``-m`` switch if you desire a different key. Below are
|
||||
a list of current key bindings:

.. _client_cli_options:
|
||||
|
||||
Command Line Options
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
A full list of command line options is available with the ``--help`` or ``-h``
|
||||
options.
|
||||
|
||||
Example: ``looking-glass-client --help``
|
||||
|
||||
Common options include ``-s`` for disabling spice, ``-S`` for disabling the
|
||||
screen saver, and ``-F`` to automatically enter full screen.
|
||||
|
||||
Options may be provided with a short form, if available, or long form.
|
||||
Boolean options may be specified without a parameter to toggle their
|
||||
state.
|
||||
|
||||
Examples:
|
||||
|
||||
- ``looking-glass-client -F`` (short)
|
||||
- ``looking-glass-client win:fullScreen`` (long)
|
||||
- ``looking-glass-client -f /dev/shm/my-lg-shmem`` (short with parameter)
|
||||
- ``looking-glass-client app:shmFile=/dev/shm/my-lg-shmem`` (long with parameter)
|
||||
|
||||
.. _client_config_options_file:
|
||||
|
||||
Configuration Files
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
By default, Looking Glass will load config files from
|
||||
the following locations:
|
||||
|
||||
- /etc/looking-glass-client.ini
|
||||
- ~/.looking-glass-client.ini
|
||||
- $XDG_CONFIG_HOME/looking-glass/client.ini (usually ~/.config/looking-glass/client.ini)
|
||||
|
||||
All config files are loaded in order. Duplicate entries override earlier ones.
|
||||
This means you can set a system-wide configuration in
|
||||
``/etc/looking-glass-client.ini``, and override specific options for just
|
||||
your user in ``~/.looking-glass-client.ini``, which is overlayed on top of
|
||||
the system-wide configuration.
|
||||
|
||||
When first launched, the Looking-Glass client will create the folder
|
||||
$XDG_CONFIG_HOME/looking-glass/ if it does not yet exist.
|
||||
|
||||
The format of config files is the commonly known INI format, for example::
|
||||
|
||||
[win]
|
||||
fullScreen=yes
|
||||
|
||||
[egl]
|
||||
nvGain=1
|
||||
|
||||
Command line arguments will override any options loaded from config
|
||||
files.
|
||||
|
||||
.. _client_overlay_mode:
|
||||
|
||||
Overlay Mode
|
||||
~~~~~~~~~~~~
|
||||
|
||||
The Overlay Mode lets you configure various runtime options for Looking Glass.
|
||||
These include:
|
||||
|
||||
- EGL filters
|
||||
- Performance metrics options
|
||||
- Debug frame damage display
|
||||
|
||||
(see :ref:`client_config_widget`)
|
||||
|
||||
You can also reposition and resize enabled widgets, like the FPS/UPS Display,
|
||||
and Performance Metrics.
|
||||
|
||||
Enter and exit Overlay Mode with :kbd:`ScrLk` + :kbd:`O`.
|
||||
:kbd:`ESC` can also be used to exit. (see :ref:`client_key_bindings`)
|
||||
|
||||
Modifications done to widgets in Overlay Mode are stored in
|
||||
``$XDG_CONFIG_HOME/looking-glass/imgui.ini``.
|
||||
Please do not manually edit this file while Looking Glass is running,
|
||||
as your changes may be discarded.
|
||||
|
||||
.. _client_config_widget:
|
||||
|
||||
Configuration Widget
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The Configuration Widget is accessible through the Overlay Mode. The
|
||||
widget has multiple tabs that allow setting a variety of modes and
|
||||
parameters for Looking Glass at runtime.
|
||||
|
||||
Settings tab
|
||||
^^^^^^^^^^^^
|
||||
|
||||
- Performance Metrics: A toggle for the Performance Metrics Widget.
|
||||
Multiple graphs are available, and they will stack vertically.
|
||||
- EGL: Modify EGL features, such as the algorithm used for scaling, and
|
||||
night vision mode.
|
||||
|
||||
Changes in the Settings tab are not persistent, and will change back to
|
||||
their default values when the client is restarted.
|
||||
|
||||
EGL Filters tab
|
||||
^^^^^^^^^^^^^^^
|
||||
|
||||
The EGL Filters tab contains options for toggling, configuring, and ordering
|
||||
post-processing filters. Each filter can be expanded to open its settings.
|
||||
Filters can also be re-ordered by dragging them up or down. Filters are applied
|
||||
from top to bottom, keep this in mind when ordering them, e.g applying CAS
|
||||
before FSR might have different results than the reverse. Users are encouraged
|
||||
to experiment with the order and parameters to achieve optimal results. The
|
||||
currently available filters include:
|
||||
|
||||
- Downscaler: Filter for downscaling the host resolution. Can be used to undo
|
||||
poor upscaling on the VM to better utilize AMD FSR (see below). The filter
|
||||
has a pixel-size setting that is used to set the effective downscaling ratio,
|
||||
and a configurable interpolation algorithm.
|
||||
|
||||
- AMD FidelityFX Super Resolution (FSR): Spatial upscaling filter that works
|
||||
on low resolution frames from the guest VM and intelligently upscales to a
|
||||
higher resolution. The filter sharpness is tunable, and displays the
|
||||
equivalent AMD quality mode based on the resolution difference.
|
||||
|
||||
- AMD FidelityFX Contrast Adaptive Sharpening (CAS): Filter that
|
||||
increases visual quality by applying a sharpening algorithm to the
|
||||
video. CAS can sometimes restore detail lost in a typical upscaling
|
||||
application. Has adjustable sharpness setting.
|
||||
|
||||
The filter settings and order can be saved to presets so that it can be restored
|
||||
at a later time. As filter settings are usually application specific, multiple
|
||||
presets can be defined for each case scenario. To save a preset, click on "Save
|
||||
preset as..." and enter a preset name. Presets are loaded by selecting them in
|
||||
the "Preset name" pull down. Presets are persistent and are stored on disk at
|
||||
``$XDG_CONFIG_HOME/looking-glass/presets``.
|
||||
|
||||
.. warning::
|
||||
Please refrain from modifying any files under the ``presets`` folder.
|
||||
Those files are meant to be modified only by the Looking-Glass client.
|
||||
|
||||
.. note::
|
||||
Although presets are persistent, the client will not remember which
|
||||
preset was used last session, so a preset needs to be recalled once
|
||||
the client starts.

Usage
|
||||
-----
|
||||
|
||||
The client command is the binary file: **looking-glass-client**. This
|
||||
command should run after the Windows Host Application has started.
|
||||
|
||||
You may run the client directly from the build directory. Alternatively, to
|
||||
install the client for all users, you can run
|
||||
::
|
||||
|
||||
make install
|
||||
|
||||
To install for the local user only, run
|
||||
::
|
||||
|
||||
cmake -DCMAKE_INSTALL_PREFIX=~/.local .. && make install
|
||||
|
||||
.. _client_key_bindings:
|
||||
|
||||
Default Key Bindings
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
By default, Looking Glass uses the :kbd:`Scroll Lock` key as the escape key
|
||||
for commands, as well as the input :kbd:`capture` mode toggle; this can be
|
||||
changed using the ``-m`` switch if you desire a different key. Below are
|
||||
a list of current key bindings:

.. _client_cli_options:
|
||||
|
||||
Command Line Options
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
A full list of command line options is available with the ``--help`` or ``-h``
|
||||
options.
|
||||
|
||||
Example: ``looking-glass-client --help``
|
||||
|
||||
Common options include ``-s`` for disabling spice, ``-S`` for disabling the
|
||||
screen saver, and ``-F`` to automatically enter full screen.
|
||||
|
||||
Options may be provided with a short form, if available, or long form.
|
||||
Boolean options may be specified without a parameter to toggle their
|
||||
state.
|
||||
|
||||
Examples:
|
||||
|
||||
- ``looking-glass-client -F`` (short)
|
||||
- ``looking-glass-client win:fullScreen`` (long)
|
||||
- ``looking-glass-client -f /dev/shm/my-lg-shmem`` (short with parameter)
|
||||
- ``looking-glass-client app:shmFile=/dev/shm/my-lg-shmem`` (long with parameter)
|
||||
|
||||
.. _client_config_options_file:
|
||||
|
||||
Configuration Files
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
By default, Looking Glass will load config files from
|
||||
the following locations:
|
||||
|
||||
- /etc/looking-glass-client.ini
|
||||
- ~/.looking-glass-client.ini
|
||||
- $XDG_CONFIG_HOME/looking-glass/client.ini (usually ~/.config/looking-glass/client.ini)
|
||||
|
||||
All config files are loaded in order. Duplicate entries override earlier ones.
|
||||
This means you can set a system-wide configuration in
|
||||
``/etc/looking-glass-client.ini``, and override specific options for just
|
||||
your user in ``~/.looking-glass-client.ini``, which is overlayed on top of
|
||||
the system-wide configuration.
|
||||
|
||||
When first launched, the Looking-Glass client will create the folder
|
||||
$XDG_CONFIG_HOME/looking-glass/ if it does not yet exist.
|
||||
|
||||
The format of config files is the commonly known INI format, for example::
|
||||
|
||||
[win]
|
||||
fullScreen=yes
|
||||
|
||||
[egl]
|
||||
nvGain=1
|
||||
|
||||
Command line arguments will override any options loaded from config
|
||||
files.
|
||||
|
||||
.. _client_overlay_mode:
|
||||
|
||||
Overlay Mode
|
||||
~~~~~~~~~~~~
|
||||
|
||||
The Overlay Mode lets you configure various runtime options for Looking Glass.
|
||||
These include:
|
||||
|
||||
- EGL filters
|
||||
- Performance metrics options
|
||||
- Debug frame damage display
|
||||
|
||||
(see :ref:`client_config_widget`)
|
||||
|
||||
You can also reposition and resize enabled widgets, like the FPS/UPS Display,
|
||||
and Performance Metrics.
|
||||
|
||||
Enter and exit Overlay Mode with :kbd:`ScrLk` + :kbd:`O`.
|
||||
:kbd:`ESC` can also be used to exit. (see :ref:`client_key_bindings`)
|
||||
|
||||
Modifications done to widgets in Overlay Mode are stored in
|
||||
``$XDG_CONFIG_HOME/looking-glass/imgui.ini``.
|
||||
Please do not manually edit this file while Looking Glass is running,
|
||||
as your changes may be discarded.
|
||||
|
||||
.. _client_config_widget:
|
||||
|
||||
Configuration Widget
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The Configuration Widget is accessible through the Overlay Mode. The
|
||||
widget has multiple tabs that allow setting a variety of modes and
|
||||
parameters for Looking Glass at runtime.
|
||||
|
||||
Settings tab
|
||||
^^^^^^^^^^^^
|
||||
|
||||
- Performance Metrics: A toggle for the Performance Metrics Widget.
|
||||
Multiple graphs are available, and they will stack vertically.
|
||||
- EGL: Modify EGL features, such as the algorithm used for scaling, and
|
||||
night vision mode.
|
||||
|
||||
Changes in the Settings tab are not persistent, and will change back to
|
||||
their default values when the client is restarted.
|
||||
|
||||
EGL Filters tab
|
||||
^^^^^^^^^^^^^^^
|
||||
|
||||
The EGL Filters tab contains options for toggling, configuring, and ordering
|
||||
post-processing filters. Each filter can be expanded to open its settings.
|
||||
Filters can also be re-ordered by dragging them up or down. Filters are applied
|
||||
from top to bottom, keep this in mind when ordering them, e.g applying CAS
|
||||
before FSR might have different results than the reverse. Users are encouraged
|
||||
to experiment with the order and parameters to achieve optimal results. The
|
||||
currently available filters include:
|
||||
|
||||
- Downscaler: Filter for downscaling the host resolution. Can be used to undo
|
||||
poor upscaling on the VM to better utilize AMD FSR (see below). The filter
|
||||
has a pixel-size setting that is used to set the effective downscaling ratio,
|
||||
and a configurable interpolation algorithm.
|
||||
|
||||
- AMD FidelityFX Super Resolution (FSR): Spatial upscaling filter that works
|
||||
on low resolution frames from the guest VM and intelligently upscales to a
|
||||
higher resolution. The filter sharpness is tunable, and displays the
|
||||
equivalent AMD quality mode based on the resolution difference.
|
||||
|
||||
- AMD FidelityFX Contrast Adaptive Sharpening (CAS): Filter that
|
||||
increases visual quality by applying a sharpening algorithm to the
|
||||
video. CAS can sometimes restore detail lost in a typical upscaling
|
||||
application. Has adjustable sharpness setting.
|
||||
|
||||
The filter settings and order can be saved to presets so that it can be restored
|
||||
at a later time. As filter settings are usually application specific, multiple
|
||||
presets can be defined for each case scenario. To save a preset, click on "Save
|
||||
preset as..." and enter a preset name. Presets are loaded by selecting them in
|
||||
the "Preset name" pull down. Presets are persistent and are stored on disk at
|
||||
``$XDG_CONFIG_HOME/looking-glass/presets``.
|
||||
|
||||
.. warning::
|
||||
Please refrain from modifying any files under the ``presets`` folder.
|
||||
Those files are meant to be modified only by the Looking-Glass client.
|
||||
|
||||
.. note::
|
||||
Although presets are persistent, the client will not remember which
|
||||
preset was used last session, so a preset needs to be recalled once
|
||||
the client starts.
