Hardware

ATI Radeon on a custom kernel

Stock ubuntu kernels include the ATI kernel source, but if you've built the kernel yourself and you're getting atiddxDriScreenInit failed errors in Xorg.0.log, you'll need to install this manually with

sudo apt-get install fglrx-kernel-source 

Reboot once the install completes, and fglrx should be good to go.

Logitech MX-1000

Feisty

Add this section to your /etc/X11/xorg.conf:

Section "InputDevice"
        Identifier      "Logitech MX-1000"
        Driver          "mouse"
        Protocol        "evdev"
        Option          "CorePointer"
        Option          "Name"            "PS2++ Logitech MX Mouse"
        Option          "Device"          "/dev/input/event4"
        Option          "Buttons"         "20"
        Option          "ZAxisMapping"    "4 5"
EndSection

where "Name" and "Device" are read from the relevant "Name" and "Handler" for your device in /proc/bus/input/devices. Then follow the remaining instructions in http://www.ubuntuforums.org/showthread.php?t=65471

Although this document describes the steps for a USB mouse, this also works when connected to the PS2 port. Note, however, that a Logitech MX-1000 forward and back keys are 8 and 9, and xvkbd is located in /usr/bin rather than /usr/X11R6/bin. In addition, as stated in the text, part 1.4 is unnecessary.

Also, I needed to append "SendCoreEvents" to the Logitech line in the layout section

Note: the error output buffer too small can be ignored.

Power management on VGA / DVI monitors

There is a standard called DPMS where a couple of pins are used for the computer to signal the monitor to go into a low-power mode. This is separate from any power management settings on the computer itself, and from the kde/gnome screensaver.

The nVidia driver fully supports DPMS, and the nvidia configuration tool typically sets it up for you. If you want to turn it off, comment out the line in the monitor section of xorg.conf.

# Option "DPMS" "true"
