What hardware are you using? I suspect the problem is with the nouveau driver, I had issues like this with my graphics card until reclocking support was finished.
Nouveau has limited support for some of the newer cards (pascal if I remember) because nvidia hasn't released the signed firmware yet. The result is low clock speeds on the graphics card, and similar issues to what you're having. Try with the official NVIDIA drivers and see what happens. https://wiki.debian.org/NvidiaGraphicsDrivers Thanks, chillfan >I have some new hardware that locks up a lot with Ascii.

I'm not a hardware person at all. _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
