→Tumbleweed: Add missing xkbcommon dependency (Package 'xkbcommon', required by 'virtual:world', not found)
libXScrnSaver-devel libXrandr-devel dejavu-sans-mono-fonts
</syntaxhighlight >
For audio support in Bleeding Edge, the following packages should also be installed:
PipeWire users:
<syntaxhighlight lang=bash>
dnf install pipewire-devel libsamplerate-devel
</syntaxhighlight>
PulseAudio users:
<syntaxhighlight lang=bash>
dnf install pulseaudio-libs-devel libsamplerate-devel
</syntaxhighlight>

* A Linux VM with GPU pass-through working (Tested With Ubuntu 21.10)
* Proxmox Host Installed and running on the Windows VM
During Proxmox 7 lifecycle they shipped a newer OVMF firmware than tested, and breaks '''kvmfr''' module. Currently the workaround is to use an older version of it:
apt install pve-edk2-firmware=3.20220526-1
apt-mark hold pve-edk2-firmware
For Proxmox 8, the current pve-edk2-firmware version 3.20230228-4 is tested to work with kvmfr 0.0.9 with Linux 6.4.3 in Linux VM. If you used the workaround mentioned above, you can revert it by:
apt-mark unhold pve-edk2-firmware
apt full-upgrade
=== Windows VM setup ===
<syntaxhighlight lang=bash>
./looking-glass-client -f /dev/kvmfr0 -c **Your_Proxmox_Host_IP** -p **spice port specified**
</syntaxhighlight>
=== Using vGPU merged driver to run Looking Glass on Proxmox Host ===
This currently only work for Windows guest, as Looking Glass Linux Host is immature at the moment.
You can simplify the guest set up by replacing the IVSHMEM settings in <code>args</code> with the following line:
<syntaxhighlight lang=bash>
ivshmem: size=32
</syntaxhighlight>
This will create a 32M IVSHMEM file under <code>/dev/shm/pve-shm-**VMID**</code>. You will need to point <code>app:shmFile</code> to this file when launching LG client.
If you want to run a Linux VM with GPU passthrough, but also being able to LG into this Windows guest in addition to from Proxmox host, you can add the following line in VM config file:
<syntaxhighlight lang=bash>
ivshmem: size=32,name=**WINDOWS-VMID**
</syntaxhighlight>
This will override Proxmox to open <code>/dev/shm/pve-shm-**name**</code> instead, and since the default for **name** is **VMID**, set that to your Windows's VMID does the trick.
Additionally you can use UNIX socket for SPICE instead of opening another port on Proxmox. This file cannot be accessed by Linux guest so only do this if you don't need access Looking Glass from another VM.
<syntaxhighlight lang=bash>
-spice unix=on,addr=/run/lg**YOUR-WINDOWS-VM-ID**.socket,disable-ticketing=on
</syntaxhighlight>
However, those 2 files will be created as root-owned. You will need to create a hook script to set the correct permissions for them (/etc/tmpfile.d was having reliability issue on my machine for IVSHMEM file, and it cannot override socket file's ownership at all):
<syntaxhighlight lang=bash>
# 3rd party script, created by the community, not part of Looking Glass project!
# Assuming you have set up a storage named `local-btrfs` and is mounted at `/var/lib/pve/local-btrfs`
