Weston RDP backend not working on iMX93

[scosta_elcoelettronica]

Hi,
I'm testing an iMX93 based SOM running Yocto Kirkstone - Linux v5.15.71_2.2.0.
I've compiled myself a full image including XWayland and Qt 6 (fsl-image-qt6). 

Weston seems to work well, but I am unable to share the screen via the RDP backend. When I activate screen sharing, I can connect to the board via Windows RDP client, but all I get is a scrambled, mostly black image:

Furthermore, the cursor in the main screen is moving very slowly.

Is there any way to make this work on iMX93?

Thanks in advance,
Stefano Costa

P.S.: please find attached my "weston.ini" file

I am having the same issue with Scarthgap on the i.MX93.

I can get RDP to work properly only if I disable use-g2d in the weston.ini. Is there a way to enable RDP with Weston while still using the g2d renderer?

The behavior works as expected when using the 6.6.36 kernel.

Hi,

I've finally managed to test Weston's RDP backend on the latest BSP (Yocto Langdale, Linux 6.1.1, Weston 11.0.1), but the result is the same:

NOTE: in order to be able to test this, I had to:

• enable the building of the RDP backend in "weston_11.0.1.imx.bb" (see attachment "weston-enable-RDP-backend.patch")
• enable the building of the server library in "freerdp_2.8.1.bb" (see attachment "freerdp-build-server-library.patch")

Any suggestion is highly appreciated

Thanks in advance,

Stefano

Hello,

You must try the latest BSP that works with the MX93 and Weston, please check it:
