Thanks for the link but its info overload Smilie I have disabled everything I can, 'suspend' and 'turn screen off' when in active. Both of which don't seem relevant to me because it happens while I'm using the PC.

I have noticed the problem doesn't present itself after a reset. The system works great after a reset, soft or hard. When I leave the system running unattended for a few hours and return it is very sluggish and the screen fade issue returns.

I'm sure you good folks good pin point the problem in minutes if you could put hands on.

At this time I consider the problem moot and don't wish to waste your time. I have installed Solaris on my other platform and prefer it's appearance over Ubuntu. I'm having issues with it that I want to focus on. When I get this issued resolved I plan on replacing this Ubuntu install with Solaris.

So, I consider this thread closed. Thank you everyone for trying to help me with this issue.

NAME
fujbp, fujhk -- Fujitsu Brightness, Pointer, and Hotkeys SYNOPSIS
fujbp* at acpi? fujhk* at acpi? DESCRIPTION
Some Fujitsu laptops come with vendor-specific ACPI devices to manage the laptop hotkeys (such as the 'Eco' button), and to control various built-in components (such as the display, the touchpad, and the speakers). The fujbp and fujhk drivers provide support, through these ACPI devices, for hotkeys, backlight on/off switch, brightness level control, and pointer on/off switch. The following sysctl(8) read/write variables are provided (when hardware support is available): hw.acpi.fujbp0.brightness Brightness level (integer). hw.acpi.fujbp0.pointer Pointer switch state (boolean). hw.acpi.fujhk0.backlight Backlight switch state (boolean). Please note, however, that future versions of the drivers may remove these sysctl(8) variables without prior notice. SEE ALSO
acpi(4), acpivga(4), sysctl(8), pmf(9), sysmon_pswitch(9) HISTORY
The fujbp and fujhk drivers appeared in NetBSD 6.0. AUTHORS
Gregoire Sutre <gsutre@NetBSD.org> CAVEATS
Brightness level and backlight switch state should be controlled via wsconsctl(8) instead of sysctl(8). The sysctl(8) variable hw.acpi.fujbp0.pointer should be replaced by a platform-independent userland control. BSD
