Bug#813: Performance drop using large virtual screen
by Hrvoje Habjanić 10 Mar '15

10 Mar '15

Package: x2goserver Version: 4.0.1.19-0~1062~ubuntu14.04.1 Hi. I noticed that using large screens (bigger than 800x600) causes x2go to start slowing down. Especially problematic are full-screen switches, for example when you switch from one virtual screen to another, inside of x2go virtual screen. This slow down is experienced as sudden session freeze, depending on screen size, it can stall for up to few seconds. After some time this becomes really annoying ... This is not influenced by switching to different encoding or line speed in GUI. Eventually i did track down to cache sizes. In /usr/bin/x2gostartagent file there is fixed cache size: "cache=8M,disk=32M". Increasing this cache size completely removes this freeze, and also significantly reduces session bandwidth! For example, with session 1680x1050, using 16bit RLE, changing cache to "64M" bandwidth drops from 3-4Mbit/s down to ~200kbit/s! I also noticed better responsiveness when using "disk=0". So, it seems that default settings (cache=8M,disk=32M) are maybe too small for todays use with lager virtual screens, and this should be increased. I would suggest using at least "cache=64M" as default. Also, it would be nice to add a possibility to change those values in a nice way, since directly editing the script is more like a hack. Also, when script is updated, changes are lost. Regards, H.

I'll be adding back the list, because this may be of interest for other people, too. X2Go Server is not using a daemon for its normal mode of operation, so there's nothing "started" (neither automatically nor manually) after installation. The init script that is automatically is merely running "x2gocleansessions" to get rid of stale/disconnected/terminated sessions. (But creating sessions will still work even with this disabled. You just may have a mess on your hands afterwards...) Every session is started by X2Go Client (or PyHoca-*) via SSH. Both launch x2gostartagent via the SSH connection to the remote server *when creating a new session*. Thus, once you install x2goserver, it's ready to use (minus special features which come in via, e.g., x2goserver-xsession.) > What is the real problem at hand? > > > Now I try to connect from a windows machine to Linux, but it doesn't work. > I checked, ssh works. > When I connect, sometimes it gives an error message like this: "failed > to suspend session with ID [...]" or the programm just gets totally > unresponsive and I have to restart it. > > Ok, that's more interesting and actually suitable for the bug report. Please start up cmd.exe, then: cd path\where\x2goclient.exe\is\installed\in x2goclient.exe --debug > debug.log 2>&1 The debug log could potentially be helpful in tracking this down.

Libdebug shows nothing...:( -------- Původní zpráva -------- Od: Mihai Moldovan Datum: 21.2.2015 Předmět: Re: [X2Go-Dev] Bug#788: Bug#788: Pyhoca-Gui freezes when connection to desktop Hi Sorry for the delay. I've noticed your message the first time around, but given that gevent is recent enough, I didn't have any additional information. I can only suggest to start pyhoca-gui with the additional parameters --debug and --libdebug to see what is going on (if anything.) Disclaimer: I have practically no idea of python in general and X2Go's python code (including pyhoca*) specifically, Mike is probably the best person to help with that.

Bug#798: Fwd: Bugs report using ssh proxy with x2goplugin
by nicolas husson 10 Mar '15

10 Mar '15

To: submit(a)bugs.x2go.org From: nicko466(a)gmail.com Subject: can't use ssh proxy with x2goplugin Package: x2goclient Version: 4.0.3.1 When I'm trying to use the ssh proxy configuration in session file with x2goplugin it seems its not working. Indeed, if you look at the session file in "~/.x2goclient/sessions" which contains all the configuration of the session of x2goclient application you will see all the descriptions of each session. Which looks like this for each session: [20150220100323537] speed=2 pack=16m-jpeg quality=3 fstunnel=true export="/home/user/Bureau/MountDistantX2goPc:1;" iconvto=UTF-8 iconvfrom=ISO8859-1 useiconv=false fullscreen=false multidisp=false display=1 maxdim=false rdpclient=rdesktop directrdpsettings= width=800 height=600 dpi=96 setdpi=true xinerama=false clipboard=both usekbd=true type=auto sound=true soundsystem=pulse startsoundsystem=true soundtunnel=true defsndport=true sndport=4713 print=true name=username icon=:icons/128x128/x2gosession.png host=localhost user=userTest key= rdpport=3389 sshport=2222 autologin=false krblogin=false krbdelegation=false directrdp=false rootless=false published=false applications=WWWBROWSER, MAILCLIENT, OFFICE, TERMINAL command=SHADOW rdpoptions= rdpserver= xdmcpserver=localhost *usesshproxy=true* *sshproxytype=SSH* *sshproxyuser=usernameProxy* *sshproxykeyfile=* *sshproxyhost=123.452.111.124* *sshproxyport=22* *sshproxysamepass=false* *sshproxysameuser=false* *sshproxyautologin=true* *sshproxykrblogin=false* The part which interest me is the bold part. Indeed, it works when i'm using this conf file with x2go client. And when i'm using x2goplugin with this configuration it doesn't work. I take a look at the network traffic and it seems that x2goplugin doesn't look at the bold part (the ssh proxy). This is why I think that x2goplugin doesn't work with ssh proxy.

[git repositories] New branching concept
by Mihai Moldovan 09 Mar '15

09 Mar '15

Hi, This information targets all users with commit privileges to the official x2go repositories. Coming up soon™, new branching policies will be in effect. TLDR: DO: - create feature branches as "feature/<name>" - comment on need for "bugfix/<name>" branches - rebase your feature branches against master - only send "pull requests" for your feature branches once they have been rebased - NO MERGE CONFLICTS! - send emails to git-admin(a)x2go.org for branch deletion, renaming or "pull requests" DON'T: - be afraid to make mistakes on your feature branches or ask - try to rebase or merge other branches into master (will be rejected) - try to delete branches (will be rejected) - try to rename branches (might leave you with a mess) Details: Historically, non-fast-forward (created by the rebase operation) and merge commits have been rejected on all branches. These restrictions will be loosened to allow committers more control over their branches and ease merging of pull requests. The new policies will allow non-fast-forwards and merge commits within feature branches. That means developers will be able to to rebase and merge other branches. In fact, committers will be required to rebase their feature branch against the master branch for pull requests. Requests with conflicts will not be merged. This new concept will not affect master and release/* branches. On these branches, rebases and merges will still be rejected. Feature branches should follow the template feature/<name> to ensure consistency with our current release/<version> release branches. The current branches will be accordingly renamed once the new policy is in effect. If you do see any benefit of a new branch type, like bugfix/<name> or bugfix/<version>, please let me know. We can then discuss policies regarding those. For now, please refrain from creating these branches. Please send an email to git-admin(a)x2go.org to initiate a pull request. Don't forget to mention the branch you want to have merged into master. The admin will review and then either merge or deny your request. This said, please try to refrain from uselessly rebasing your branches to delete mistakes or squish commits together, unless it really makes sense. Don't be afraid to be human. Commit early, commit often. Don't forge the history. For renaming and deletion of branches, please also contact git-admin(a)x2go.org. Creation is possible without former notification of git-admin, but please make sure to follow naming conventions as outlined in this email. The new policies will be effective once implemented and Mike#1 finishes the outstanding release of all components. Best Mihai
