I use Ubuntu 17.04 and haven't seen that error.  Which version of Ubuntu are you using?  Chances that the "Inappropriate ioctl"  is unrelated to session saving (Error 25 is from something checking if a file is actually a terminal and our code doesn't do that directly).  Was there a traceback in the log window in addition to the error message?  If so, please send it to us.  And please tell us if was the session file saved correctly, ie., can you reopen it in ChimeraX?  With that information, we'll have a better idea of how to fix it.

Regards,

Greg

Hi Elaine,

I am a new user of chimeraX. I run it (the daily builds on 17th Oct 2017) in my Ubuntu system. All went well until I tried to save the session. An error message '[Errno 25] Inappropriate ioctl for device' popped out. Could you please give me some advice to fix it? Many thanks.

Kind regards, Yahui

Hi Yahui, I don’t know the answer, but I’m sharing it to the mailing list: chimerax-users@cgl.ucsf.edu … that is the recommended address for ChimeraX questions. Regards, Elaine
