Those were the errors right before I removed the virtual display.

I removed the looking-glass-host.ini file after I couldn’t get passed the first error. So that may be it.

Yes, correct, the virtual display is not supported. The new errors re IVSHMEM are due to the device missing or drivers not installed. Seems you broke something when you removed the virtual device. Check Device Manager for the IVSHMEM device.

Please also note you have used a really old tutorial, your method of setting up the ivshmem device using custom arguments is deprecated. Please follow the official quickstart guide here:

https://looking-glass.io/wiki/Installation

Reinstalled the host software and I still have the same issue. I followed that but not in the exact order as listed–not numerically indicated. It’s only visually indicated.

It’s not the host software, please check device manager as I have now asked twice. Make sure the IVSHMEM device is present and has it’s driver loaded.

Yup, its working.

I tried to connect a monitor with my dock but it has to go through some dual link technology–don’t know whether that needs additional setup. I’m exhausted. I’m going to sleep.

Its dell d6000. and my xps 9500 has no display/hdmi ports. although I do i have a basic type to usb and hdmi adapter.

It looks right to me.

Even still I still suggest you use Intel GVT-g instead of looking glass as it will natively give you your VM’s display without the overheads associated with LG.
