To make a long story short, I've recently had to install LFS-7.2 on a
VIA mini-ITX board with a C7 CPU and CN700 (S3 Unichrome Pro) video.
With the xf86-video-openchrome-0.3.1 driver, the X screen comes up with
a semi-transparent green "film" in a 16-bit color depth. It doesn't
happen with 24-bit depth, but that can slow things noticably with a 1GHz
Pentium-III equivalent low-power CPU. The problem can be found reported
with a Google search, but I found no recommendations. Here's what
worked, and didn't, for me.
I tried the 0.3.3 and 0.4.0 drivers, but no joy. Then I fell back to
the 0.2.906 driver, which does work, but floods the log with an error
message: "VIA EXA download src_pitch misaligned". OK, so the driver
isn't perfect, and does have glitches, but it works well enough for me
and forthcoming fixes are unlikely. I made the attached patch to shut
off the error message.
This may be somewhat "historical" at this point, but it's a path I was
forced to tread this week. Google will search this list, so perhaps it
will help someone else in this position.
