[PD] set screen resolution from within Pd (Linux)

[Ingo]

Hi there!

Is it possible to set the screen resolution from within Pd in Debian (with
or without externals)?
If yes how?

My problem is that some older mainboards automatically default to
"1280x1024".
If I set the screen size in /etc/X11/xorg.conf to "1920x1080" it still shows
everything with the lower "1280x1024" resolution.
It actually doesn't respond to setting it to a lower resolution either . . .

Not sure if I would need different graphic drivers for that.
I'm on Debian-9.5.0-i386.

Thank you!
Ingo
