This server does not provide start menu data

[stdedos]

I'm hitting

xpra/xpra/client/gtk3/tray_menu.py

Line 1478 in 54d9c76

start_menu_item.set_tooltip_text("This server does not provide start menu data")

but I don't understand why:

$ xpra showconfig | grep start-

The server log should have more details.
Perhaps the -d exec flag would help here.

I'll do a -d exec

[totaam]

Looks good.
Perhaps this is a compatibility bug with v6

[stdedos]

Sadly, xpra upgrade -d exec is not enough to trigger this. I'd do a

        xpra control "${backend}" debug "${action}" "$l";
        echo "$ xpra control '${backend}' debug ${action} '$l' (\$?:$?)";
        xpra control "${backend}" client debug "${action}" "$l";
        echo "$ xpra control '${backend}' client debug ${action} '$l' (\$?:$?)";

but I'd guess this is at-startup thing 😕

[totaam]

My bad, I was a bit too aggressive in removing legacy flags.
v5 servers still need this one: fdff997
