Looking Glass Beta 3 Release Candidate 1

With 364 commits since Beta 2 I am very excited to announce the Beta 3 release Candidate 1.

If you are still using Beta 2 please be sure to read through the changelog below before upgrading.

A big thank you to the contributors that have helped to get Looking Glass to where it is today! Your support is greatly valued!

As usual, you can find the latest source archive and host executable on the LG website at: https://looking-glass.io/downloads

If you like this project and find it useful and would like to help out you can support me directly using the following platforms.

Changelog:

  • OBS: Added full cursor support
  • All: Added HDR RGB16 support
  • Client: show system strerrr for failure to open shmem file
  • All: added frame format version field and format change events to avoid checking on every frame.
  • Client: new option win:dontUpscale to prevent upscaling.
  • Client: new shortcut, ScrLck+V to toggle the video feed when using a dedicated monitor.
  • Client: reworked event logic fixing several stutter issues
  • Host: service won’t start if there is no IVSHMEM devices available.
  • Client: Direct DMA Upload from IVSHMEM for VM-VM configurations using the KVMFR module. (Removes a CPU memory copy). Note: Will not work with NVidia Linux GPU binary drivers due to lack of DMABUF support.
  • Host: increased the cursor shape buffer size for large cursors (you may need to increase your ivshmem memory size!)
  • Client: EGL only - Added Color Blind support for Protanope, Deuteranope and Tritanope (option egl:cbMode) as per Daltonize.org: Daltonize
  • Client: added large clipboard transfer support
  • Client: now defaults to grabbing the keyboard when focused (shortcuts are now passed to the VM), can be disabled with input:grabKeyboardOnFocus=n
  • Client: Spice input handling has been re-designed and is far improved.
  • Cilent: Fixed bug with EGL initialization which prevented front-buffer rendering when doubleBuffering is disabled (default).
  • Host: Installer much prettier thanks to @JJRcop
  • Host: Fixed issue with launching on pre-windows 10 systems (note: I am not testing on anything older then Windows 10, YMMV)
  • VM-VM Module: fixed building on 5.10 (note, /dev/uio0 is now gone, use /dev/kvmfr0 instead)
  • Client: New option input:ignoreWindowsKeys to work around WMs that bind the key
  • Client: New keybind ScrLck+Windows to passthrough the key to the guest for WMs that bind this key.
  • Client: Now processes mouse input via XInput, giving access to raw mouse input while in capture mode (enable with input:rawMouse).
  • Client: New autoCapture mode (disabled by default, enable with input:autoCapture), tries to keep the mouse captured without entering full capture mode when a game/application in the guest also has captured the mouse. Note this is NOT full capture mode and as such will not benefit from input:mouseSens or input:rawMouse. (please no bug reports for failure to hold onto the mouse, this is best effort only).
  • Client: New input:mouseSmoothing option (enabled by default) which applies basic integration on the mouse movements when not in raw mode (capture enabled and input:rawMouse on). This helps to reduce aliasing artifacts in movements on the guest.
  • Client: New input:captureOnly feature (default disabled) to only enable input via SPICE while in capture mode.
  • Client: New win:rotate feature to rotate the display output (EGL only at this time).
  • Client: New hotkey ScrLck+R to rotate the display on demand.
  • Host: Now properly supports rotated display outputs.
  • Client: Thanks to xyene and quantum on the VFIO discord, Wayland is mouse support is greatly improved and clipboard sync is now working. (NOTE: this is not an announcement of general Wayland support, Xorg is still the preferred platform due to Wayland limitations).
  • Host: when installed as a service it is now able to capture the windows login screen.
  • Host: Numerous QOL NvFBC fixes.
  • Host: The service will now terminate if the application reports a fatal error, or the application is closed by the user via the tray icon.

Great work! When can we expect install binaries?

You can download them now at Looking Glass - Download Looking Glass (as noted in the OP)

Just upgraded from B2 to B3-rc1. Recompiled the binary for Linux and went into Windows using an external monitor and installed the new version. However I get no video output on Linux. Is there something else I need to change?

Increase your IVSHMEM memory size

Thank you a lot, this solved my problem!

I have a different question still. On version B2 I opened the LG window and pressed F11 for fullscreen and then ScrollLock to capture the input devices. To get out of LG and work in a different window I did the reverse, first ScrollLock and then F11 to decrease the window size. Currently I do not know how I can got to fullscreen mode since when I hover the mouse over the LG window or the LG window border and press F11 the key press is redirected into the VM and whatever window I have open in the VM goes fullscreen not LG.

Please update to B3-rc1, it implements full keyboard grab.

I am on B3-rc1-0-g185c7764ba.

I am sorry but your WM then is grabbing the key in such a way that we can not override it. We see the same behaviour on KDE with the Windows Key.

Thank you for your quick answer. Then I will revert back to B2 for now, which worked fairly well and update to B3 as soon as this is resolved.

I am on Gnome by the way.

Sorry I misunderstood your problem… it is supposed to redirect the key press to the VM when it’s focused, however there is an option to revert to the old behaviour. Set input:grabKeyboardOnFocus=no

Thank you, that’s it! I often switch in and out of the VM and this helps a lot. Everything is working great now.
