Re: XFree86 4.0.2 and Matrox G400
Hello James,
The answer was in there:-)
First of all though, I switched to the 2.4.1 kernel, re-compiled, and it
made no difference - I still got an error about mga_hal missing.
I had a look at matrox.com and found the new drivers that one of the
other posters had mentioned, and on the same page: a download for
mga_hal. I downloaded both and installed them - the mga_hal was no
longer missing in XFree86.0.log. Unfortunately, it made no difference
to the performance. Very odd - no error messages that I could find, but
still poor performance. I noticed that if I tried 24/32 bpp I got:
(EE) MGA(0): [drm] Insufficient memory for direct rendering
My G400 has 16MB, running at 1600x1200 screen res.
ssystem -bench gave me the same results on both 16bpp and 24/32bpp! -
about 11fps. No errors with 16bpp but still not working.
Then I saw your posting and spotted ***1) Install xlibmesa3 (this will
remove/replace mesag3 libraries)***
Awww....
I still just had mesag3
Installed xlibmesa3 and now get 77fps (with two seti clients running
backgrounded - SMP) in 16bpp, 44fps at 1600x1200 fullscreen.
Still get the Insufficient memory error when I use 24/32bpp and fps
drops to about 5fps :-(
Sad, as 32bpp is fine with X3.3.6 & utah_glx. At some point I'll try a
lower res in 24/32 and if that works I'll consider getting a 32MB card,
assuming that 16MB isn't enough for DRI at 1600x1200. If anyone can
actually confirm that this is the problem I'd appreciate it.
See, it was something obvious after all:-)
Thanks,
LeeE
