I will definately give those suggestions a shot. Looks like I need to read a little more into the past to see what problems I face in my future.
Hopefully we can get you the Quadro you need to further development. Don’t have a whole lot being in education but I hope the little i can contribute helps.
Good luck on your ventures and thank you for being such an approachable developer and role model for those young ones looking at the open source space. Too offten they get hit with the old RTFM mentality.
I’m trying to use the Looking Glass software to help me display output from my kvm to a window so that I don’t need an external montior (thus keeping the portability of a laptop) and am running into some issues. The looking glass quick setup does not talk about using virt-manager and instead uses the qemu command line. I’m not sure how the qemu command line works and there seem to be no tutorials on how to set this up using virt-manager. In my research I started seeing that optimus cards can not even do VGA passthrough, so am what I am trying to do even possible? And if so, how do I do it? Are there alternatives that would achieve the same results with similar performance to looking glass?
i cant get looking glass host to work on windows.
the GPU is passed through and its driver is installed.
when i run the command prompt as administrator and issue looking-glass-host.exe -f
this error happens.

Press enter to terminate…
not sure if it matters, but the VM’s graphics card is an AMD radeon RX 590.
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.
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.
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.
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
