Hi Alexander Kriegisch (kriegaex), I don't have any problem with it on Ubuntu 12.04 (speedlinux) Did test with this example: http://monkeypatch.me/blog/move-a-running-process-to-a-new-screen-shell.html Best regards, Johann Pascher 2012/2/3 <col...@li...>: > Send coLinux-users mailing list submissions to > col...@li... > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.sourceforge.net/lists/listinfo/colinux-users > or, via email, send a message with subject or body 'help' to > col...@li... > > You can reach the person managing the list at > col...@li... > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of coLinux-users digest..." > > > Today's Topics: > > 1.

Well, actually I succeeded now with simple examples like one-process, one-I/O-channel stuff, e.g. a long-running "find /" on one console, transferring it to another. I could not manage to get a "mc" session to another TTY though. Maybe this is because of the sub-shell in mc. But I am also failing at a simple "make menuconfig" because make also has a sub-process (mconf). I can only transfer "leaves" of a process tree, i.e. the mconf instance itself. Do you succeed in doing such stuff? BTW: Why is the reply-to header wrong in this list and I am always replaying to people privately in the first try? -- Alexander Kriegisch (kriegaex) http://freetz.org Johann Pascher, 03.02.2012 18:40: > Hi Alexander Kriegisch (kriegaex), > > I don't have any problem with it on Ubuntu 12.04 (speedlinux) > Did test with this example: > http://monkeypatch.me/blog/move-a-running-process-to-a-new-screen-shell.html > Best regards, Johann Pascher > > 2012/2/3 <col...@li...>: >> Send coLinux-users mailing list submissions to >> col...@li... >> >> To subscribe or unsubscribe via the World Wide Web, visit >> https://lists.sourceforge.net/lists/listinfo/colinux-users >> or, via email, send a message with subject or body 'help' to >> col...@li... >> >> You can reach the person managing the list at >> col...@li... >> >> When replying, please edit your Subject line so it is more specific >> than "Re: Contents of coLinux-users digest..." >> >> >> Today's Topics: >> >> 1.
