--- Comment #8 from Nikita Sirgienko <warqu...@gmail.com> --- Well, this is also well known problem, that Octave plotting via ftlk can work incorrect and hang during plotting in some linux distros. At least in Cantor for sure. So I think, you can try to disable "Embedded" option in Octave (but ftlt window can also hang itself) or run 'graphics_toolkit("gnuplot")' command before plot command and check, is that solves your problem with hanging. And if it have solves the problem, then you can just add the graphics toolkit change command in Cantor Octave autorun command, or in Octave startup file itelf. Additional info about ftlk: On my Ubuntu 20.04 ftlk not working correctly like from Ubuntu 16.04. In early versions we just always have switched from ftlk to any other graphics toolki, but Cantor have had some bugreports about this solution and additional research have showed, that on some distros its work smooth, so we stop to change toolkit and leave graphics toolkit manipulations in user's hand. -- You are receiving this mail because: You are watching all bug changes.
