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

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.
