Re: [X2Go-User] New x2go broken on Ubuntu 17.10

 Ha ha well I have lots of hairs but they're all grey.  Anyway, hope you
get to spend some of Christmas enjoying it!  We got the first white Christmas
in a decade here.

  In particular the -geometry 800x600 even though I'm set at a screen
resolution of 1920x1080 (and it is displaying at the correct resolution in
spite of that).


We're always starting whole display sessions with a geometry of 800x600 (which
corresponds to the default width and height). You're right that this is probably
a bit weird, but the window is resized to the correct size later on and nxagent
adjusts to that.

This is pretty much also true for rootless sessions (in which case the window is
also immediately resized to spawn the whole display).

Real fullscreen sessions get a geometry value of "fullscreen" instead.

It doesn't really matter to much if resizing is working properly. We could avoid
a useless resize operation by pre-determining the display size and passing that
as the initial geometry, but there isn't all that much to gain.



  Memory usage of nxagent does not seem unreasonable to me, 282k of which
81k is in core.  FIrefox is around 4GB at times.


That's good to hear! I hope to have squashed most memory hog situations, that
mostly boiled down to bugs in the new logging code during the last few days and
weeks.

The issue I talked about in my last mail boiled down to using the new -d
parameter with nxproxy and enabling info or debug output. Staying on the default
warning log level didn't lead to it eating memory quickly, but even so that
issue should also be gone now.


This update cost me a few hairs lately.

Great, at least we've got that.

The new architecture still is a bit weird in that it deletes all RandR modes but
the one that was detected on the remote (i.e., client-side) screens, so changing
the resolution within the session itself won't be possible.

This shouldn't be a huge problem in general since resizing is still possible in
windowed mode and irrelevant in whole display or fullscreen modes.


Other than that, be aware that the new version still has other unresolved bugs,
which include a huge memory footprint within nxproxy (server/client mode),
slowdowns for no apparent reason (though only one user so far has reproduced
this), random application crashes for software that uses a lot of X resources
(e.g., Firefox/Pale Moon, Audacity, KDE Plasma, fvwm2, ...) and sudden
connection drops (which may be related to the previous slowdowns and have so far
only been experienced by one user).

 I see that you pushed another update today on Christmas.  Things still
