✔️ Expected Behavior

XRDP running as systemd service

❌ Actual Behavior

does not run as service - but via "xrdp-sesman -n & xrdp -n &"

Anything else?

Copied from #2221

The 'SYS' is down to xrdp using a system call it's not allowed to. See #2697

• What version of xrdp are you using now (git log -n1 will give us the commit)
• What do you get for sudo grep sig=31 /var/log/syslog

    Fix regression in using window message names (#2925)

    FreeRDP defines macros WM_LBUTTONUP, WM_LBUTTONDOWN, WM_RBUTTONUP
    and WM_RBUTTONDOWN. These conflict with the definitions we have in
    xrdp_constants.h. Because the FreeRDP system includes followed the local
    includes however, the compiler did not emit a diagnostic for this -
    see gcc bug #16358.

    This PR rearranges the includes for NeutrinoRDP so the macro
    redefinitions are flagged by the compiler.

Try applying ccead29 to /usr/lib/systemd/system/xrdp.service

That was the fix - thank you for your great work @matt335672
