Try disabling in windows the QXL, or other video card you have present in device manager. Sounds crazy but is exactly what I’m doing. When you do this you will loose video in your spice client and only have looking-glass and external displays to use.

thank you, now it just works.
however, the windows desktop is very low resolution, and windows is unable to change its resolution in display settings. is there any way to fix that?
under the “radeon RX 590 Series properties” tab from the display settings, if i hit “list all Modes” it only shows “640x480, true color (32bit), 59 hertz” and “640x480, true color (32bit), 60 hertz” as options.
UPDATE: ive tried running the half life 2 lost coast benchmark on my VM with looking glass while stuck in this low-re mode. it got 82fps, which is very odd as the host has the same GPU and gets several hundred FPS in that game,
What kind of external display do you have connected? You will need to have some sort of termination on the GPU still. Can be a monitor or if you are solely wanting to use looking glass, a dummy connector.

i do not have any physical monitor connected to the VM’s GPU. Looking-Glass’ website frontpage states that it eliminates the need for a physical monitor.
i do not currently own a monitor that is compatible with the VM’s GPU.
Without something on the GPU, it will not be able to negotiate resolutions. I recommend a HDMI dummy plug like this.
As for the preformance, is it a q35 or a 440 based VM?
pc-i440fx-3.1
so is it not possible to create a true headless gaming VM? only one with a false monitor on the GPU?
Not without a dummy plug. Nothing looking glass can do to bypass that. The GPU needs to see a display connected.
As for more performance, a q35 based machine will give better results. Check out this thread, time of info in it.

so i now have a monitor and am trying to play a game with looking glass. but everytime i launch a game looking glass host crashes with this error
DXGI.cpp:328 | Capture::DXGI::Initialize | DuplicateOutput1 Failed: 0x80070005 (Access is denied.)
[E] Service.cpp:190 | Service::ReInit | ReInitialize Failed
not sure if it matters, but i have looking glass running at login by having it added to the registry setting stated in the quickstart guide. i appened the -f switch to this registry setting so that i could see on the monitor any errors that might happen.
Please provide the full output from the host when running it in foreground mode.
looking-glass-host.exe -f

Make sure that you have set the permissions on the shm and that it is added to the virtual machines definition.

DuplicateOutput1 Failed: 0x80070005 (Access is denied.) is a capture API failure and has nothing to do with the ivshmem device. I really need to see the entire output to have a hope of diagnosis.

Press enter to terminate...In future please use the Preformatted Text option for log posts, I have edited your post to do so.
Clearly it isn’t just crashing, it is switching modes several times and then fails with a permission denied error.
- What game/application are you launching when this occurs?
- Is it every single time, or random?
- Are you running any other capture software that might be competing for access to the capture API when you launch a game?

i am using no other capture software when this happens.
this happens everytime i launch any steam game (from the 4 that I’ve tried) in fullscreen mode.
i have tried these games: half-life 2: lost cost, Left 4 Dead 2, Resident Evil 5, and Half Life 2.
I’ve noticed that everything works just fine when i launch the games in windowed mode, only fullscreen causes this.

Have you enabled steam in house streaming? This is competing capture software.

No, Steam’s In-home streaming is disabled.
i’ve done some testing, this problem does not happen with Resident evil 6 on Steam.
i plan to test more games as my VM downloads them.
this problem also does not happen with subnautica
ive noticed that the only games that give me issues are the one’s that run at resolutions other than 1920x1080
I’m trying to setup looking glass, however I’m stuck at this message when running the host application on windows:

More importantly, are you following this guide?
