==Hardware==

IBM ThinkPad A31p
80gb hdd
1gb ram
2x cd-rw/dvd
wireless/ethernet/modem/firewire/bluetooth
Radeon Mobility FireGL 7800
1600x1200 15" TFT active matrix flexview

==Software==

Fedora Core 3 Linux

==Projects==

Currently working on a set of ACPI scripts for /etc/acpi/actions and /etc/acpi/events. I made several scripts that manage various aspects of the hardware (power management, usability etc). These scripts control the following ACPI events: ac_adapter, lid, powerbtn and sleep.

Additional options for the radeon driver

Sehh:

==AGP speed==

By default, the open source radeon driver forces 1x AGP speed. Quote from the developers:

tuning to the highest speed possible has caused hangs on some boxes, with no
discernable pattern, so we default to 'slow but safe' whilst giving the option
to go fast if the user wants to try it.

Higher speeds can be enabled by adding '''Option "AGPMode" "X"''' (where X is a number) in the '''Device''' section in /etc/X11/xorg.conf.

Section "Device"
Identifier "Videocard0"
Driver "radeon"
VendorName "IBM Thinkpad"
BoardName "ATI Mobility FireGL 7800"
'''Option "AGPMode" "4"'''
EndSection

With this option enabled (set to 4x speed), the X11 server should print (/var/log/Xorg.0.log):

(**) RADEON(0): Option "AGPMode" "4"
(**) RADEON(0): Using AGP 4x mode

==AGP Fast Writes==

By default, the open source radeon driver disables AGP Fast Writes. Fast Writes can be enabled by adding '''Option "AGPFastWrite" "yes"''' in the '''Device''' section in /etc/X11/xorg.conf.

Section "Device"
Identifier "Videocard0"
Driver "radeon"
VendorName "IBM Thinkpad"
BoardName "ATI Mobility FireGL 7800"
'''Option "AGPFastWrite" "yes"'''
EndSection
