I just ran linetest both with the buggy XFree 4.3.0 version of

FYI: Klaus Peichl just confirmed that the e1 value was wrongly
calculated, and that replacing
e1 = major;
by
e1 = minor;
fixes the bug. Fix committed to CVS.

Hello Thomas,
I have found a module that would enable the use of
certain older hardware with Linux (Mandrake 9.1 for
PowerPC platforms). On the webpage below, what
constitutes the actual code (and is it usable or do I
need a different format such as RPM or .gz) and how to
install it?
Here is the

What I see from comparing the code is that the 3.3.6 version does a lot

If you are feeling motivated, take a look at s3_accel.c and see if you
can find the bug in the implementation of SolidBresenhamLine.

Take a look at the XF86Config man page. You can find out exactly which
XAA routine is causing the bug by trying the different XAANo
oprions, where XXX is the acceleration routine. they are listed in the
man page.

Cool, thanks a lot!
It works well with the option
Hello XFree team,
