One is on a similar problem. I'm not sure if it is Windows + X or a Firefox issue. I'll include more details on the email on performance - John ___ X2go-Dev mailing list X2go-Dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev

Re: [X2go-Dev] 3.99 Testing - Very serious issues with image packing
Is there some way to enable debugging or very detailed logging with the Windows x2go client? With all the different problems people are seeing, it seems the only chance at solving them is to have detailed logs. I am having a very strange problem with x2goclient 3.99 and 64-bit Windows 7, but I am having a hard time reproducing it. The problem is bizarre. When running firefox (4 or 5), if I have one tab open with gmail, and another tab, then sometimes the firefox menus and toolbar almost completely freeze up and firefox stops responding (technically, it seems to be responding once every minute or so, one click at a time). At first I thought this was a firefox bug, but then I found that after firefox started freezing, sometimes it would freeze up the rest of my applications (gnome-terminal, thunderbird, etc.) and then release them again in a minute. Also, it NEVER happens with x2goclient 3.01-13. I can install 3.99, start a session, have the problem, then suspend the session, install 3.01-13, resume the session, and the problem is gone. But if I resume the session again in 3.99, sometimes the freezes happen again. And sometimes not. I haven't figured out a repeatable way to get the freezes, but they do seem to require a firefox tab with gmail open. ___ X2go-Dev mailing list X2go-Dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev

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. Grml...

[X2go-Dev] 3.99 Testing - Very serious issues with image packing
Hello, all. This seems to be the most serious and potentially showstopping issue I've found. It is a Windows only issue. It does not occur in our Linux client testing. 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. 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. I did uninstall ghostscript and vcxsrv after uninstalling Pyhoca. 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.
