Hi Tom,

...

When I tried to save the view (as a png or jpeg picture, for example), I always got error 25 "Inappropriate ioctl for device
". What does that mean? How can I export the 3D view as a figure?

...

Best,
Dan

Dan reports:
,.. I am running ChimeraX on Ubuntu 16.04. I have tried both File / Save... and the command save <destination path>. Both of them yielded that error, which I could not understand. I will try with the windows version.

Best,
Dan

Hi Dan,

The image saving error “Inappropriate ioctl…” is something to do with your system, it is linux right? We had this reported one other time on linux but the person never got back to us. So we don’t know how to reproduce it. What linux distribution are you using? Are you using the File / Save… dialog or the save command? Maybe the command won’t have this problem (e.g. “save ~/Desktop/someimage.png”).

FYI, I don't have this problem when running the daily build on Ubuntu 17.10. But I agree that it should work on Ubuntu 16.04 too. I assume you're running a fully updated Ubuntu 16.04? And that is 16.04.3? And can you send us the which graphics device you're using (run "lspci | grep VGA" in a terminal) and what its capabilities are (run "glxinfo" in a terminal)? Many thanks, Greg

Hi Greg,


Please find attached the output of the two commands in the text file. Thanks for taking care of this!


Best,

Dan

Reproduced. The bug is that Python's os.getlogin() fails on Ubuntu 16.04 and ChimeraX is not expecting it to fail. Fixed in the next successful daily build.
