From the GNOME configuration menu, the T640 appears to be already using X11 windowing. Maybe the 1100W PSU from the R720 would provide sufficient power for the T640?
Additional RAM is required in the R350 before this can be done.
It has occurred to me that the Wayland desktop may be causing issues with the GPU. I should try booting to Xorg or sans desktop before more intrusive methods are attempted.
The R720 chassis appears less suited for this purpose than the T640. Additionally, the R720 will likely be most useful on the network as a dynamic QEMU hypervisor; however, it would still be…
I am experimenting with installing the GPU on a PowerEdge R720 with Arch Linux instead of Debian (which was previously able to utilize the device).
This may be an issue with matrix.org or the result of a new account being used. Will continue to monitor.
