Geoffrey McRae 358171ff8b [client] main: preserve restart after primary video loss
Primary frame and pointer workers can still be unwinding an abandoned
payload when another thread detects that the primary transport has
disconnected. Their fatal paths previously stored SHUTDOWN
unconditionally, allowing a stale renderer or transport failure to
overwrite RESTART and terminate the client instead of activating the
SPICE fallback.

Publish RESTART at the beginning of primary-loss handling, before
transport bookkeeping, and make worker-local fatal paths transition to
SHUTDOWN only while the application is still RUNNING. Global failures
and the case where both primary and fallback sessions are lost remain
terminal.

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.
