Hi,
Just wanted to share my experiences of upgrading to 4.2.0.
I installed SuSe Linux 7.2 (X 4.0.3) and upgraded it to 4.1.0 a few months ago. This
was fairly traumatic as I was new to Linux and (I think) I compiled from source.
Nevertheless, it resulted in a stable platform that (with KDE 3.0) is fast and
responsive. I was particulally impressed that my monitor can now display 1024�768
(after a lot of tweaking), whereas Windows can only manage 800�600.
I have now installed Mandrake 8.2 (X 4.2.0) and I can boot into either distribution,
with the same kernel (or their pre-compiled kernels).
I was a little dissappointed to find the screen was noticably _less_ responsive with X
4.2.0 -- more tweaking. In the 'readme's I found that the sis driver had been
improved, and XAA had been completely reimplemented; and the logs showed another
difference.

Screen to screen bit blits
Solid filled rectangles
--- 8x8 mono pattern filled rectangles
--- Solid Lines
+++ Solid Horizontal and Vertical Lines
Setting up tile and stipple cache:
--- 32 128x128 slots
+++ 16 128x128 slots
--- 10 256x256 slots
+++ 4 256x256 slots
I assume this is due to a limitation of memory space, but I don't have any extra
modules (that I'm aware of) taking up VRAM. Are there extra features implemented that
need their own slice of VRAM? Can these be disabled? Would I get extra
slots/rectangles in return?
If the problem is memory constraints, is there any way to use the other half of the
8MB on my card, that is lieing idle, or a MB or 2 of system memory? (it is AGP).
