Comment 25 for bug 196617

Just wanted to add that I'm experiencing this problem with :

00:00.0 Host bridge: ATI Technologies Inc RS480 Host Bridge (rev 01)
00:01.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge
00:05.0 PCI bridge: ATI Technologies Inc RS480 PCI Bridge
00:13.0 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller
00:13.1 USB Controller: ATI Technologies Inc IXP SB400 USB Host Controller
00:13.2 USB Controller: ATI Technologies Inc IXP SB400 USB2 Host Controller
00:14.0 SMBus: ATI Technologies Inc IXP SB400 SMBus Controller (rev 11)
00:14.1 IDE interface: ATI Technologies Inc IXP SB400 IDE Controller
00:14.3 ISA bridge: ATI Technologies Inc IXP SB400 PCI-ISA Bridge
00:14.4 PCI bridge: ATI Technologies Inc IXP SB400 PCI-PCI Bridge
01:05.0 VGA compatible controller: ATI Technologies Inc Radeon XPRESS 200M 5955 (PCIE)

and ForceMonitors doesn't work for me either.

I have also tried commenting out DPMS in the monitor sections :

Section "Monitor"
 Identifier "Laptop Monitor"
# Option "DPMS"
EndSection

Section "Monitor"
 Identifier "Samsung Monitor"
# Option "DPMS"
EndSection

and adding the following to the ServerLayout

 Option "BlankTime" "0"
 Option "StandbyTime" "0"
 Option "SuspendTime" "0"
 Option "OffTime" "0"
...
none of which helps either the monitor blanking out and system freezing - or the Xorg.0.log file from bloating with errors.

Could there be a link between the Xorg log file growing in size to the system crashing?

Anyone else experiencing similar / related issues?
