Adding startup service
To ensure a service which exists in /etc/init.d is run on startup, simply run:
sudo update-rc.d <service> defaults
Enabling Printing
- /bin/chmod 06555 /usr/bin/lpr /usr/bin/lprm
- /sbin/chkconfig lpd on
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
Add this section to your /etc/X11/xorg.conf:
Section "InputDevice" Identifier "Logitech MX-1000" Driver "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.
In newer versions of X11, it seems that evdev is a driver rather than a protocol, so you'll need the line:
Driver "evdev"
rather than
Driver "mouse" Protocol "evdev"
Also, I needed to append "SendCoreEvents" to the Logitech line in the layout section
Convert m4a to mp3
- Ensure libfaad2-0 and ffmpeg (from medibuntu) are installed, and run:
ffmpeg -ab <bitrate in kb/s> -i <inputfile> <outputfile>
Note: the error output buffer too small can be ignored.
Changing default ALSA soundcard
asoundconf list asoundconf set-default-card <cardname>
List hardware details
sudo lshw -businfo
Add swap space
- Create swap partition using fdisk
- Create swap filesystem
sudo mkswap <device>
- Activate swap
sudo swapon <device>
- Modify /etc/fstab to allow swap to be activated at boot time
Change userid/groupid for an existing user/group
- Change groupid in /etc/group
- Run sudo grpconv to update /etc/gshadow
- Change userid in /etc/passwd (and also the primary groupid for any changed groupids)
- Run sudo pwconv to update /etc/shadow
