kodi-rpb and Forcing 800x480p Resolution

[adamArch]

First time posting, my apologies if it doesn't fit within the usual guidelines...

Okay. Here goes. I'm using the following hardware:

-Raspberry Pi3
-Raspberry Pi Official Touchscreen Display

-Touchscreen has a resolution of 800x480p.

Kodi does not like this screen when running in Arch. It forces a display resolution of 1280x720p, and has the setting greyed out so that I cannot change this resolution within the Kodi interface.

The touchscreen is connected using the DSI port and not an HDMI cable. I have manually set this in /boot/config.txt with the hopes of forcing the resolution within Kodi, but it did not change anything.


hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt=800 480 60 6 0 0 0


This display works excellently with my XFCE desktop environment running with Xorg. The display also works flawlessly when I've used OpenELEC with Kodi on it right out of the box; no configuration needed, Kodi picks up the resolution on ELEC with no issues.

Can you help me to force the 800x480p resolution that I need for a perfect display on Kodi while still running Arch ARM?
