If you're not a robot but a human, speak words about the issue you want to solve. Not just copying & pasting logs.

I think i have the same issue. And i'am not sure but maybe since kernel upgarde to linux510. (i use manjaro xfce)
The impact of this issue is that i can't use any mouse or keyboard input.

In the absence of any other information from the OP, I'm going to assume that this issue means the following:-

1. This line in libxrdp/xrdp.c should be logging a DEBUG message instead on an ERROR message:-

xrdp/libxrdp/libxrdp.c

Line 1196 in c76c580

LOG(LOG_LEVEL_ERROR, "libxrdp_query_channel - Channel %d name %s", index, channel_name);

2. This logic in xrdp/xrdp_mm.c

xrdp/xrdp/xrdp_mm.c

Lines 662 to 670 in c76c580

	while (libxrdp_query_channel(self->wm->session, index, chan_name,
	&chan_flags) == 0)
	{
	chan_id = libxrdp_get_channel_id(self->wm->session, chan_name);
	out_uint8a(s, chan_name, 8);
	out_uint16_le(s, chan_id);
	out_uint16_le(s, chan_flags);
	index++;
	}

needs to be modified somehow to not call libxrdp_query_channel() with an invalid index.

The first of these is being addressed by PR #1742

I'm changing the title of this fault report to match my assumptions above.

@angelsion - if this isn't your intention, please feel free to open another issue which describes your problem clearly.

@SH160388 - you've clearly got here with an internet search for an error message. Feel free to open a separate issue which describes your problem clearly.
