Fabio Rossi via Cygwin <cygwin AT cygwin DOT com> · Thu, 27 Apr 2023 18:15:53 +0200 (CEST)

Hello Brians,
thanks for the suggestions. I had already installed the xorg server and all the packages you mentioned. But nevertheless I get the errors reported in the original email, both if I start octave from the shell or by using the XDG menu which starts octave with the GUI.

In particular, in the second case I confirm all the opengl messages already reported and I get the following results in the octave command line:

>> getenv('XDG_CURRENT_DESKTOP')
ans = X-Cygwin
>> getenv('XDG_MENU_PREFIX')
ans = xwin-
>> getenv('XDG_RUNTIME_DIR')
ans =

From the shell all of the previous variables are of course empty. With the past versions of octave it was plotting when run from the bash.

Thanks,
Fabio

On the same machine, octave built for Windows executes correctly the same command. I have observed the same behaviour also on other Windows machines running Win7 or other graphic adapters.
