I've posted some previous messages about the Xserver
problem I am having. I have a G4 533 dualie Snakebit
I am running Debian unstable. I am using ICEWM.
The machine came with the GForce 2MX.
When I start up X it runs for several minutes fine.
At some point it appears to stop. I can still move
the mouse cursor around. I put a debug statement
in nv_xaa.c at the suggestion of Mark V. The statement
checks if NVSebsequentScanlineCPUToScreenColorExpandFill
arguments w and h are ever zero.
I put in a statement like this:
if( w==0 || h==0 )
ErrorF( "w=%d, h=%d\n", w, h );
I've looked through the XFree log and no error was
printed. Where should this error message go if it
is triggered?
The other thing I noticed when looking at "top" output
is that the X server seems to be stuck in a loop as it is
eating 50% CPU and 2.5% Mem. I have 768MB on this machine.

Linux pmac 2.4.18-ben0 #2 SMP Sat Mar 9 10:22:24 EST 2002 ppc unknown
How can I get X to give up some more debug information?
How do a find out what 0x1027e118 is?
Attaching to the XFree server shows:
