X11 sometimes crashes. Why?

[debian_noob at web.de]

Hi again,

I have another problem. This time with X11.

Sometimes X crashes after booting and shows some
"down gliding pixels" (I don't know how to describe
so I included a picture of my monitor after such crash.).

I don't know what that is. For a complete I post here
my lspci and the XFree log.

Here is my "lspci":
0000:00:00.0 Host bridge: Intel Corp. 440LX/EX - 82443LX/EX Host bridge (rev 03)
0000:00:01.0 PCI bridge: Intel Corp. 440LX/EX - 82443LX/EX AGP bridge (rev 03)
0000:00:0d.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
0000:00:14.0 ISA bridge: Intel Corp. 82371AB/EB/MB PIIX4 ISA (rev 02)
0000:00:14.1 IDE interface: Intel Corp. 82371AB/EB/MB PIIX4 IDE (rev 01)
0000:00:14.2 USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB (rev 01)
0000:00:14.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 02)
0000:01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G100 [Productiva] AGP (rev 02)

Here is my XFree log (I include only the WW lines; I can give you the other lines if it is important):
(WW) The directory "/usr/lib/X11/fonts/cyrillic" does not exist.
	Entry deleted from font path.
(WW) The directory "/usr/lib/X11/fonts/CID" does not exist.
	Entry deleted from font path.
(WW) `fonts.dir' not found (or not valid) in "/var/lib/defoma/x-ttcidfont-conf.d/dirs/CID".
	Entry deleted from font path.
	(Run 'mkfontdir' on "/var/lib/defoma/x-ttcidfont-conf.d/dirs/CID").
(WW) Open APM failed (/dev/apm_bios) (No such file or directory)

Can someone please describe me what is going wrong?

regards
