Cirrus Logic GD5446/5480
Last modified: 2008-05-01 11:37:56 EDT
One machine with a Cirrus Logic GD5446 based display adapter with 1 meg of
video ram shows the first GUI screen in broken up form. In a text install
when X is configured the X test screen is also broken up. Using
Xconfigurator after install, the test screen is also broken.
The installation chooses the SVGA server, which I believe is correct.
This card worked fine in RHL 6.2
This also happens with the integrated GD 5480 of Intel L440GX+ motherboards.
It is fixed by Option "no_bitblt" in the XF86Config, so maybe it should be
enabled by default for cirrus boards (the later ones anyway?)
Using the accerated driver in XFree86-4.0 works even better, that's what I've
done in CVS.

Still there in Fairfax. And 3.3.6 is what gets selected
(and 4.0.3 has the same problem)
And to avoid confusion, this was about 5480, in the kudzu database it says
# reported not working on SGI 1200 as of 02/22/2001

I'd suggest a no_bitblt for 3.3.6 on this board (and for 4.0.x
it's something else, maybe just noaccel and be done with it)
Reassigning to XFree86 and changing assignee..

Somehow this bug got assigned to msw.. Reassigning to myself.
There is a new Cirrus logic fix I've just made in the newest XFree86
4.1.0-0.9.8 package not yet available in rawhide.
4.1.0-0.9.11 from rawhide works perfectly for me, even without the
I changed the bug to Xconfigurator, which needs the following to make it
use 4.1.0 instead of 3.3.6:

Also make sure anaconda uses 4.1.0 on these boards.
5446 probably needs something similar, but I don't have the hardware
to test if the fix works on those too.
