Geoffrey McRae 423269802f [client] evdev: fix input capture and device handling
Classify configured devices by keyboard and pointer capability so
automatic keyboard capture leaves relative pointer devices with the
display server.

Run descriptor, grab, physical-state, and LED operations on one worker.
Marshal normalized events through each display server's event loop and
serialize ownership changes with per-lane barriers.

Fall back whole lanes to native input when an evdev cohort cannot be
owned, and retry missing or removed devices without disabling the rest.

Handle report framing, SYN_DROPPED, high-resolution wheels, queue
overflow, held-state cleanup, and guest-driven keyboard LEDs. Restore
host LEDs and kernel grabs during teardown.

Re-evaluate capture when the active input transport changes.

Looking Glass

Looking Glass lets you use a Windows virtual machine from Linux with very low display and input latency. The current recommended setup uses the Looking Glass Indirect Display Driver (IDD) in the Windows guest and the Looking Glass Client on the Linux host.

Start here

The Linux client is currently distributed as source code and must be built before it can be installed. The end-user guide covers the complete process:

  1. Build the Linux client.
  2. Configure shared memory for the virtual machine.
  3. Install the Looking Glass IDD in Windows.
  4. Install and run the client.

See the Looking Glass documentation for the current requirements and setup guide.

Source archives

IMPORTANT

This project contains submodules that must be checked out if building from the git repository! If you are not a developer and just want to compile Looking Glass, please download the source archive from the website instead:

Source code for the documentation can be found in the doc directory.

You may view this locally as HTML by running make html with python3-sphinx and python3-sphinx-rtd-theme installed.
