I'm running a Proxmox on a NucBoxG3. After some problems I could establish a Solus pve on it.
I connect via SPICE and have got a resolution 1920 x 982 on my 21" Display
Here are the parameters on Proxmox:
CPU Type: x86-64-v2-AES
Bios: SeaBios
Display: SPICE (qxl)
Maschinetyp: q35
SCSI-Controler: Standard (LSI)
Drive: SATA0 (very important)
NET: Virtio
That's, what systemsinfo says:
