Fernando,
I've seen similar log entries from working systems so I'm not sure it's
necessarily the issue, however given the uniqueness of your setup I
agree it'd be good to be able to specify some parameters in order to
test things further.
That said I don't believe there's any easy way to go about this - you'd
need to alter the code directly. A couple of pointers on that may be
obtainable here:
https://lists.apache.org/list?user@guacamole.apache.org:2021-8:guacd%20pass%20additional%20args
and here: https://lists.apache.org/thread/0lx5ypm6t0ndwgy0cp8m8nsqp5zmnzdf
Otherwise it may be that others on the list have experience with your
issue/setup, or are able to provide much more informed assistance.

Hi Ivan,
Thanks for your ideas!
I made some further debugging with remmina and guacamole. I found a
difference in the connection they establish:
Reminna:
Local framebuffer format PIXEL_FORMAT_BGRX32
Remote framebuffer format *PIXEL_FORMAT_BGRA32*
Guacd
Jan 12 10:17:06 ip-172-33-33-54 guacd[698589]: Local framebuffer format
PIXEL_FORMAT_BGRX32
Jan 12 10:17:06 ip-172-33-33-54 guacd[698589]: Remote framebuffer format
*PIXEL_FORMAT_RGB16*
I suspect that for some reason guacd is not detecting the "remote
framebuffer format PIXEL_FORMAT" correctly and that leads to a faulty
rendering but no idea about how to force it. Is there any setting to
force BGRA32 for a connection? (i think the problem is in guacd because
I am using the same freerdp packages from ubuntu but, of course, not sure)
I built guacd but used the ubuntu packaged freerdp development files.

I thought about that at first but the same guacamole setup is being able
to connect to a win10 box, 2008r2 box and a ubuntu xrdp box... my
feeling is that the client is able to render.
thanks,
Fernando

In Remmina, if you've set up a connection, you can edit that connection
to see some of the settings it uses (colour depth for example). You can
also turn on a debug window which may show more - although I've seen
mixed comments on that.
I suppose it's possible you have two or more versions of FreeRDP on
your
system. It could be worth checking that before going too far - to see
what Remmina's using first find the plugin:
dpkg -L remmina-plugin-rdp | fgrep remmina-plugin-rdp.so
(my Ubuntu 18.04 shows
/usr/lib/x86_64-linux-gnu/remmina/plugins/remmina-plugin-rdp.so)
then:
ldd /usr/lib/x86_64-linux-gnu/remmina/plugins/remmina-plugin-rdp.so |
grep libfree
should show the FreeRDP version.
If you compiled Guacamole from scratch you'll know if this is the same
version you introduced then. If it is then you'd generally expect it to
work as it does with Remmina (all commands being equal), if not then
there could be some subtle differences so you'd need to proceed with a
degree of caution.
Note that being the same doesn't necessarily mean that Guacamole must
work, all you're doing at this point is trying to eliminate a few
possible issues so that it's easier to focus closer to where the issue
might lay.
Having said all that I don't recall seeing much about your Guacamole
installation? I seem to recall some possible issue with graphics if a
proxy is in use, so if the problem persists it could be worth checking
that and/or letting is know more about your setup.
One other thing that's also worth doing before going too far is simply
to clear your browser cache - that's caused many a problem in the past.
That probably exhausts my ideas at this point, however going through
these things may well assist others to more readily identify the actual
issue...
