[sage-support] Re: Sage does not start from desktop icon
Hello Alejandro, what happens, if you enter the command notebook(open_viewer=True) at the sage console? Also try: properties of the Icon, Application tab, Advanced options, Do not close when command exits. Watch for error messages. I have a certain suspicion, that sage tries to open a viewer, that does not exist. You can set the viewer with the environment variable SAGE_BROWSER, for example (one single line at the unix console): SAGE_BROWSER=firefox sage -c notebook(open_viewer=True) which execute the command after the -c option. Try a full path instead of firefox, if there are problems. Also try: sage -c notebook() Another possibility is: sage -notebook If one of these works (the last two are equivalent to 1. starting sage 2. executing notebook() and this seems to work for you), use one of the two lines in your SAGE-notebook.desktop file, for example: Exec=/usr/local/bin/sage -notebook With best regards, Lars --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Hello Lars what happens, if you enter the command notebook(open_viewer=True) at the sage console? The notebook opens the same, apparently, as with the command 'notebook()'. Also try: properties of the Icon, Application tab, Advanced options, Do not close when command exits. Watch for error messages. Right now I am in Gnome, and Properties of the Icon does not have an Application tab. I will switch to KDE and tell you later. I have a certain suspicion, that sage tries to open a viewer, that does not exist. You can set the viewer with the environment variable SAGE_BROWSER, for example (one single line at the unix console): SAGE_BROWSER=firefox sage -c notebook(open_viewer=True) which execute the command after the -c option. OK. This is bash and Debian Etch has Iceweasel, not Firefox...iceweasel is in the path. Then I executed at the shell: export SAGE_BROWSER='iceweasel sage -c notebook(open_viewer=True)' This sets the SAGE_BROWSER environment variable, but does not improve making the icon work. Also try: sage -c notebook() This is curious. I get this output on the console: === The notebook files are stored in: /home/jakubi/.sage//sage_notebook ** ** * Open your web browser to http://localhost:8000 * ** ** 2008-07-15 13:09:22+ [-] Log opened. 2008-07-15 13:09:22+ [-] twistd 8.0.1 (/usr/local/sage-3.0.2- debian32-intelx86-i686-Linux/local/bin/python 2.5.2) starting up 2008-07-15 13:09:22+ [-] reactor class: class 'twisted.internet.selectreactor.SelectReactor' 2008-07-15 13:09:22+ [-] twisted.web2.channel.http.HTTPFactory starting on 8000 2008-07-15 13:09:22+ [-] Starting factory twisted.web2.channel.http.HTTPFactory instance at 0xb6b33a4c === Then a new Iceweasel window opens with the Sage group homepage (http:// www.sage.com/ ) in the first tab and my worksheet list (http:// localhost:8000/home/admin/) in the second tab. With Ctrl-C in the sage console, it closes with these messages: === 2008-07-15 13:15:34+ [-] Saving notebook... 2008-07-15 13:15:34+ [-] Saving notebook... 2008-07-15 13:15:34+ [-] Notebook cleanly saved. 2008-07-15 13:15:34+ [-] Notebook cleanly saved. 2008-07-15 13:15:34+ [-] Main loop terminated. 2008-07-15 13:15:34+ [-] Server Shut Down. === Another possibility is: sage -notebook The same effect. use one of the two lines in your SAGE-notebook.desktop file, for example: Exec=/usr/local/bin/sage -notebook This works: it opens the worksheet list in a new tab (in the same Iceweasel window where I am editing this post). It has not opened a Sage group tab (I will see again when I post and close Iceweasel).

Confirmed, with Exec=/usr/local/bin/sage -notebook in the SAGE-notebook.desktop file, it opens a Gnome terminal window with the messages copied in to the previous post and it opens Iceweasel with the worksheet list.

Lars, Also try: properties of the Icon, Application tab, Advanced options, Do not close when command exits. Watch for error messages. Now in KDE I have done this and got this error message in the konsole: === File /home/jakubi/notebook.py, line 3 notebook(open viewer=True) ^ SyntaxError: invalid syntax === The other form of desktop file does not work yet here as it opens Konqueror, which gives some other errors. Presumably this is well known (because of the advise to use Firefox). I will see to change the (default) browser to Icewasel in KDE also.

[sage-support] Re: Sage does not start from desktop icon
Thank you, that was. I have removed notebook.py that was generated wrong (see above) and clicking on the icon makes the notebook session open. However, it still opens a console window that remains after I close the notebook session. I can close it with Ctrl-C. Is this the expected behavior? If unavoidable that this console window opens, is it possible to get it open minimized and close automatically when I close the notebook? Also, the link http://www.sagemath.org/art/ after this sentence For a picture for your icon, check out the Sage art at, in http://www.sagemath.org/doc/html/inst/node11.html is broken Where do I get the Sage icon picture?

[sage-support] Re: Sage does not start from desktop icon
I do not know why two posts were generated as I have sent once. May be worth adding that Sage starts OK from the console, and the notebook interface opens fine using the command notebook() at the sage prompt. By the way, the link http://www.sagemath.org/art/ after this sentence For a picture for your icon, check out the Sage art at. Where do I get it?
