WTware RDP client

No, sorry

It was hacked off from kernel due to incompatibility with ZaphodHeads X.org functionality. Is I know, wtware is only linux that runs zaphodheads mode dual display on raspberry and we need this functionality to run Chromium on one display and don't allow it to interact with RDP session on another display. But we can only run it after erasing all but hdmi from raspberry video driver...

Hello WTware Community,

I have a Raspberry Pi 4B with the official Raspberry Pi Touch Display 2 (720×1280, DSI port directly connected) and I'm trying to run it in Landscape mode under WTware 6.2.62 (PXE netboot).

Setup
Pi 4B, WTware 6.2.62 PXE boot
Display: Raspberry Pi Touch Display 2 (DSI, 720×1280@60, official docs: raspberrypi.com)
Config in MAC folder: C:\ProgramData\WTware\Terminals\<MAC>\cmdline.txt

Problem
NONE of the DSI video parameters work - black screen in all cases:
Tested cmdline.txt variants (single line each):

text
video=DSI-1:720x1280@60,rotate=90 wtboot=pxe
video=DSI-1:720x1280@60,rotate=270 wtboot=pxe
video=DSI-1:720x1280@60,rotate=0 wtboot=pxe
Kernel boots cleanly in ALL cases, parameters accepted (see logs below)

NO display output during boot OR WTware session (black screen)
Without custom cmdline.txt: Display works in default portrait mode

Logs (rotate=90 - NO display)
text
[ 0.xxx] Kernel command line: video=DSI-1:720x1280@60,rotate=90 wtboot=pxe
(Full bootlog attached)

Logs (rotate=270 - NO display)
text
[ 0.xxx] Kernel command line: video=DSI-1:720x1280@60,rotate=270 wtboot=pxe
(Full bootlog attached)

Questions
Does Touch Display 2 (DSI) work officially with WTware? Missing dtoverlay=rpi-display or similar boot config?
Correct cmdline.txt syntax for DSI panels? (DSI-1 vs DSI-0? Different format?)
DSI video parameters completely disable display - known limitation/bug in WTware?
Do I need a terminalspecific config.txt with DSI overlays (dtoverlay=vc4-kms-v3d,rpi_display=1)?
Working alternative: HDMI controller board needed for DSI panels under WTware?
Goal: Stable 720×1280 Landscape (physically rotated or rotate=270). Default portrait works fine without custom cmdline.txt.

Thanks for your help!
