note XRDP problems when disabling Screen Blanking

[buhtz]

I added information about a possible side problem with XRDP when disabling Screen Blanking.

Beside my own experience I also found some postings in the net about this. But the connection between Screen Blanking and XRDP-mouse-input is still unknown.

@XECDesign or @spl237 Any ideas about this? Is this an appropriate change to make to the documentation?

[spl237]

No idea, but it seems unwise to change the documentation until the problem is understood - screen blanking really shouldn't affect XRDP sessions, so just documenting that it does is not the best solution...

If the Xorg session (xorgxrdp package) is used, then this is the reason: neutrinolabs/xorgxrdp#164

• With an X11 layout override config in place, the XRDP input drivers are/were not loaded anymore. And raspi-config installs one when disabling screen blanking: https://github.com/RPi-Distro/raspi-config/blob/master/usr/share/raspi-config/10-blanking.conf

There are two different solutions provided in the issue, test the latter one used by the maintainer, which is present on Debian Bullseye as well: https://github.com/neutrinolabs/xorgxrdp/pull/181/files (apply to /etc/X11/xrdp/xorg.conf)

It seems to me like this is not a documentation issue: rather it should be raised as a bug against the Raspberry Pi OS distro for the relevant package maintainer to take a look. It appears that the bug is in an upstream package so should probably be escalated upstream, but that's up to the relevant maintainer of Raspberry Pi OS to decide.

This doesn't seem like a docs issue. I'm closing, and I think the OP should raise an issue against the Raspberry Pi OS repo if they haven't already done so.

As said, all fixed upstream, provided downstream with Bullseye already.
