X used to crash on my intel D865GBFL, RH9.

I upgraded the BIOS so far.

The following pre-crash indicator still appears in XFree86.log:
(normal user ONLY!):

GetModeLine - scrn: 0 clock: 0
GetModeLine - hdsp: 800 hbeg: 0 hend: 0 httl: 0
vdsp: 600 vbeg: 0 vend: 0 vttl: 0 flags: 0



For root ONLY, I get this line:

AUDIT: Fri May 14 12:03:28 2004: 4976 X: client 4 rejected from local host


Question:
---------
1. What does GetModeLine ... mean?

2. Why the difference between root and normal users?


Thanks.
