Suspend and resume physical session
by David Roth 11 May '10

11 May '10

Hi, is it possible to suspend a physical session and to resume it with x2go (Or to somehow "transfer" a physical session to an x2go-session and backwards)? Consider the following scenario: 1) Developer starts his machine and prepares an application/presentation he wants to present in the meeting room 2) Developer suspends his local session and wants to reopen this session from the meeting room and he wants exactly the session state he has left on the desktop. 3) After the meeting the developer wants to go back to his workstation and resume the suspended session. I already know that it's possible to suspend a x2go-Session but what i want is something like Windows Remote Desktop. best regards, david

Larger-scale X2GO installations - experience?
by sm8ps-x2go1＠yahoo.com 08 May '10

08 May '10

Dear all, I have been looking for a suitable set-up for our high school (Swiss Gymnasium, grades 10 through 13, 400 students, 60 teachers) that would allow our students to use their own netbook/laptop in class as well as at home. Conditions are: 1. no technical support for users' computers (therefore no installing individual applications, no passing out images etc.) 2. must work on computers in any state, even with broken OS, browser whatever (so must allow terminal server solution as fall-back) 3. plattform independent (win/mac/linux and independent of individual computer models) 4. must work over WLAN 5. should be available on- as well as off-site A couple of years ago I started looking more closely into LTSP and I have set up a test lab that works just fine. Though, the local nature of that makes it less suitable to our needs. Clearly, I have studied NX and now I have followed the development of X2GO more or less closely. I feel that X2GO is the perfect candidate and I want to set up a larger-scale test network. Before doing so, however, I would like to hear other people's experience with such set-ups. I have compiled a preliminary list of questions (s.b.). If you have any experience with larger scale X2GO set-ups, I would really appreciate your input and I think others might be interested as well. Thanks a lot for sharing your expertise! If you would like to communicate in German or French, I can cope with both. Cheers!

Custom paper size for cups-x2go.ppd
by John A. Sullivan III 03 May '10

03 May '10

Hello, all. We have a client who needs to use the x2go printing system to print to plotters for construction drawings. They need to be able to specify custom paper sizes. For example, I am on site right now and they need to print 30" x 36" drawings. What would be involved in editing the cups-x2go.ppd file so that they can specify a custom paper size? We had hoped to offload that job to the local print driver but, when we tried to do this with the cups-x2go printer, it sent an A4 sized image and printed it on 30" x 36" paper. Thus it seems essential for the cups-x2go driver to send the custom sized document in the first place. Thanks - John

Shared drive icon cleanup
by John A. Sullivan III 03 May '10

03 May '10

Hello, all. We've been having a problem with the icons created when one shares a local share with the X2Go desktop not being cleaned up on Windows computers. It works fine when the client is Linux. This could be peculiar to our highly customized setup. Has anyone else noticed this? We set up a bit of tracing and found the $remote variable used to delete the icon in the x2goumount_session script was being prepended with _cygdrive_: May 3 15:54:39 vd01 X2GOUMOUNT TRACE : remote is /vservers/joe/data/users/joe/Desktop/_cygdrive_C_DOCUME~1_Joe_X2GO~1_S-BDE3~1_spool May 3 15:54:39 vd01 X2GOUMOUNT TRACE : remote is /vservers/joe/data/users/joe/Desktop/_cygdrive_C_DOCUME~1_joeold We edited x2goumount_session to read: $remote=~s/\//_/g; $remote=(split(":","$remote"))[1]; $remote=~s/^_cygdrive_//; $remote="/vservers/$serv/data/users/$uname/Desktop/$remote"; As you can tell, we have customized this for a vserver environment - something we hope to publish very soon. This then gave us the expected results on Windows stations.

X2GO Screen Refresh Performance
by --[ UxBoD ]-- 29 Apr '10

29 Apr '10

Hello all, I am looking for a little bit of explanation on how the X11 session is delivered to the X2GO client; and whether improving the performance of the local X11 server would improve the overall experience? As a reference point I ran x11perf while connected to a remote X2GO session with the following results: x11perf -copywinwin10 x11perf - X11 performance program, version 1.2 The X.Org Foundation server version 60900000 on :54.0 from uxbod Thu Apr 29 15:18:53 2010 Sync time adjustment is 0.0263 msecs. 36000 reps @ 0.1401 msec ( 7140.0/sec): Copy 10x10 from window to window 36000 reps @ 0.1460 msec ( 6850.0/sec): Copy 10x10 from window to window 36000 reps @ 0.1457 msec ( 6860.0/sec): Copy 10x10 from window to window 36000 reps @ 0.1424 msec ( 7020.0/sec): Copy 10x10 from window to window 36000 reps @ 0.1450 msec ( 6900.0/sec): Copy 10x10 from window to window 180000 trep @ 0.1438 msec ( 6950.0/sec): Copy 10x10 from window to window when I run the same test on my physical laptop which has a NVidia Quadro card I get: x11perf -copywinwin10 x11perf - X11 performance program, version 1.2 The X.Org Foundation server version 10604000 on :0.0 from cyborg Thu Apr 29 15:19:18 2010 Sync time adjustment is 0.0979 msecs. 2400000 reps @ 0.0020 msec (492000.0/sec): Copy 10x10 from window to window 2400000 reps @ 0.0021 msec (486000.0/sec): Copy 10x10 from window to window 2400000 reps @ 0.0020 msec (502000.0/sec): Copy 10x10 from window to window 2400000 reps @ 0.0020 msec (488000.0/sec): Copy 10x10 from window to window 2400000 reps @ 0.0020 msec (496000.0/sec): Copy 10x10 from window to window 12000000 trep @ 0.0020 msec (493000.0/sec): Copy 10x10 from window to window Reading one of the NX documents about slow performance it mentions: "Upgrading to a more recent version of the X server or trying a different video driver can surely offer a great boost. For example a hardware accelerated video card is recommended to obtain the best speed." Would one of the devs be able to cast some light on where I should look to tune the performance? -- Thanks, Phil

Re: [X2go-dev] Problem with charsets (folder mapping - windows to linux)
by Alex 27 Apr '10

27 Apr '10

Александр, здравствуйте! Я нашел временное решение: в скрипте монтирования /usr/bin/x2gomountdirs добавил параметр umask=0000 для команды sshfs. И после, проброса папки на сервер, я выполняю под пользователем скрипт, анализирующий папку media в home директории и в случае наличия в ней проброшенной папки, выполняется команда: convmvfs /home/$USER/folder -o srcdir=/home/$USER/media,icharset=CP1251,ocharset=UTF8 папка folder конечно же должна быть создана. Конечно это некрасивое решение, но видимо иного быть не может. Потому как, если изменить скрипт монтирования под кодировку cp1251, то возникнут проблемы с Linux --> Linux связкой. Есть мысль, создать копию x2gomountdirs с параметрами для монтирования cp1251, а в windows-клиенте сделать опцию, монтировать в русской кодировке. Я, правда, не уверен, что это возможно. Т.к. не влезал пока в принцип работы самого сервера и клиента. Но если бы это было возможно реализовать, думаю, решились бы многие проблемы, потому что не только с русской кодировкой могут быть проблемы, арабская, иврит, китайская и т.д. И причем именно в связке Windows --> Linux Should i translate my message? Or i can post in russian?

Problem with charsets (folder mapping - windows to linux)
by Alex 26 Apr '10

26 Apr '10

Hi, thank you for your project, it is amazing! Primarily, excuse me for my English. I have one problem with folder mapping... The situation is that I want to use x2go in Russia. And the mapping folders from Windows to linux hampered difference charsets (cp1251 and UTF-8). So, how can I mount the Windows folder converting in UTF-8? there is such a fuse-convmvfs, but I do not know how to implement it in a script to mount the folder. I am waiting for your help! Thanks!!!!

x2go local printing sends to pdf app
by John A. Sullivan III 21 Apr '10

21 Apr '10

Hello, all. We are in the home stretch of our first major X2Go deployment and have hit a problem with using the x2go cups printer to print to local devices. When Windows users print to the X2Go printer and select a physical printer from the list of local devices, we find the print job is opened by whichever application is configured to open PDF files. For example, we had one station where the print jobs opened in Acrobat Standard no matter what printer we sent the job to. We removed Acrobat Standard and the job now opened in Acrobat reader. I'm assuming this is a bug. Is it something I have misconfigured? We really want the job going where we send it and not to a PDF reader (unless, of course, we tell it to go to the PDF reader!). Thanks - John

Binary packages for Fedora
by Pavel Lisý 16 Apr '10

16 Apr '10

Hello guys Recently I've found this piece of software which is really missing. Previously I've played with nomachine stuff but it is not fully free. I would like to help with creating packages for Fedora. There is only x2goclient-cli command-line (not finished yet) I've tried it in Ubuntu but I'm little bit confused with too many packages there. Have you any suggestion how to split it to packages? And what is necessary for server part and which version you suppose to use for build like this (latest or older)? Thanks Pavel

Hi, i would like to ask, if there is any chance to load the Settings for the Windows x2go-Client from any other place than the Registry? Thats the only Problem if one wants to run it as an PortableApp... Many thanks! Tobias
