Bug#1133829: How I solved the issue

It seems that during the operating system installation, the default
settings that were supposed to enable “nomodeset” by default were
configured incorrectly.


After renaming the /etc/X11/xorg.conf file, everything started working as
it should, and performance in DW increased to 35–40 FPS—I think that's
about what it was like on Windows.
