HDIMI 1024x600p60 Does not work

I use armbian with 5.15.119 kernel version. Display P08-RT2660TP-MAIN-1.0
Panel can work with 1080p60hz with resize mode. And work only with Android.
Is there any ways to get it work with 1024x600p60hz at ubuntu fenix or armbian?

Hello @AcnupuH

It is a known issue for 5.15 kernel, we are working on it and fix on next release.
