[sage-support] Re: tutoriatutorial() tries to start wine under gnome-3.12
It is a sage-on-gentoo install. I will report the issue on https://github.com/cschwan/sage-on-gentoo/issues .

In this case report it on github at https://github.com/cschwan/sage-on-gentoo/issues It may be that your problem would also occur with a vanilla sage but there is no way to know other than building a vanilla sage and trying again.

I can't open notebook either in a gnome-session, it fails with Could not find the Mozilla runtime. Setting SAGE_BROWSER=firefox does not change anything. Under xfce I can open the notebook without problems. Because my sage is a sage-on-gentoo install, I will report the details on https://github.com/cschwan/sage-on-gentoo/issues https://github.com/cschwan/sage-on-gentoo/issues .

Under gnome this issue seems to lock after some time the whole desktop. Several existing terminal windows do no more respond and it is impossible to start new application with the application menu. tutorial() merely opens up the default browser, and a local copy of the tutorial HTML docs in it. By the way, what is your default browser? I never saw this reported as causing problems. Could you try doing notebook() rather than tutorial() ? (notebook() will also pop up your default browser, and then open Sage notebooks in it). -- You received this message because you are subscribed to the Google Groups sage-support group.
