Something is seriously wrong with image packing. I'm guessing this has something to do with NXAgent 3.5 but I'm really not sure. It first appeared when I install Pyhoca which I am assume pulled in the new agent.
x2goagent/nxagent runs on the X2go server, not at all on the client!!! What comes with x2goclient/PyHoca-GUI are:
nxproxy.exe + libxcomp3 + some cygwin stuff
pulseaudio.exe
vcxsrv.exe (a complete vcxsrv installation in case of PyHoca-GUI, a minimal
set of files in case of x2goclient)
On the other hand, reverting to 3.0.1-4 did not fix the problem which has me very suspicious. I am writing from Linux right now but I will test that again later. If it is not the nxagent or the 3.99 client, then we'll need to find whatever it was that Pyhoca pulled in.
Everything that PyHoca-GUI installs ends up in %ProgramFiles%\PyHoca-GUI. Erase that dir and you should be clean again.
I did uninstall ghostscript and vcxsrv after uninstalling Pyhoca.
Ok...
I can confirm that the problem persists even after backleveling to 3.0.1-4 so I'm not sure that this is specifically 3.99 but it is a crippling problem.
:-(
On to the actual problem. We normally use 16m-png-jpeg packing which seems to give us the fastest performance and crispest looking screen on our WAN only environment.
I can confirm the performance improvement when running pyhoca-gui and x2goclient on Linux.
I'm honestly not sure what this setting controls. I assume it means we are compressing png and jpeg images as opposed to the default 16m-jpeg which then only compresses jpegs? I don't know what the 16m is - is that the size of the cache?
No clue, actually. That is NX stuff...
When we use that from a Windows client now, all the images are thoroughly corrupted and unusable. This was noticeable in the desktop icons and in the KDE splash screen. We changed the packing to 16m-jpeg and thought the problem went away because the splash screen and desktop icons appeared properly. Our enthusiasm was short-lived. All jpegs seems to be corrupt. The only way we could get a non-corrupt screen was to use nopack but that made for lousy performance especially when scrolling a graphics intensive page such as www.wsj.com or www.cnn.com.
YUK!!!
Interestingly, even after upgrading, the client details screen says we are running NXPROXY - version 3.4.0.
Ok... it maybe that the new x2goclient 3.99.0.0 for Win32 still uses old NX code on the client side. PyHoca-GUI still comes with nx 3.4.x.
BTW: the diff between the last libxcomp3 (3.4.x) and libxcomp3 (3.5.x) is very small!!!
I don't know what in the Pyhoca installation caused this but completely removing Pyhoca and previous x2goclient installations from both file system and registry and installing 3.99 has not fixed the problem. Thanks - John
I have tested PyHoca-GUI and x2goclient on Win2008r2 64bit right now (via rdesktop). Both actually fail, the nxproxy/x2goagent is most of the time not even opened, sometimes it pops up, but then it is gone.
