I've now had some time to test this out. Currently gnome-shell is not
usable with llvmpipe:
1. The screen flickers when switching between applications, or when
entering/leaving overview mode. The flickering is between the
correct screen contents and a copy of the old screen contents.
For instance, while typing this message I go into overview mode.
I then click on Evolution's composer window, and the composer
comes to the front. However, after the animation finishes, only
the composer's text entry area is visible; the rest of the
screen still displays the overview mode. The other applications
are still present, however, as clicking where I know the windows
are placed causes them to flicker to the foreground. The
applications themselves seem functional, but it'such impossible
to actually use them. This behaviour does not show up if I use
gnome-shell's screen recording feature to make a movie. I took a
grainy movie with my phone however; you can see it at
2. There is a small but noticeable delay between an event occurring
(e.g., pressing a key on the keyboard, or moving the mouse) and
the screen being updated. Worse, the delay is variable (hold
down a key while gedit has the focus and characters appear at an
uneven rate). This may be another aspect of whatever is causing
the first issue.
3. The mouse pointer continually warps to the top-left corner of
the screen, triggering the overview mode at random. This is a
bug in the evdev input driver, filed as
I can try building mesa with LLVM 3.1, and/or try some of the patches at
<http://pkgs.fedoraproject.org/cgit/mesa.git/tree/?h=f18> if you think
they will help.
