Why is the disk imager not working? If the imager can't find the root partition, chances are it is either a bad hard drive (try another drive first), an improperly connected hard drive, or the little IDE adapter is burned out. They burn out periodically. Check the back of the adapter for burned marks. Ask someone if you are unsure.
Hibernate problems When a hard drive is moved from one laptop to another, hibernate may fail to work. In at least some cases, this is because the drive is being recognized as /dev/sda, rather than /dev/hda.
  • make sure that the swap partition is a logical partition (not primary) e.g. /dev/sda5
  • make sure that /etc/fstab shows the swap as the correct device.
  • in /boot/grub/menu.lst make sure that there is the following line.
# defoptions=resume=/dev/sda5
  • run "sudo update-grub" afterwards (might need to run "sudo grub-mkdevicemap" first)
Weirdly large font in login Login screen looks fine until you put in the username, which is in a huge font (larger than the input field):This is a bug in the X server which reports the screen size as 289x21 mm. In the final sense it is something that will be fixed in a future version of X, but for now there is a workaround. In the "Screen" section of xorg.conf, put in the following line: Option "DDC" "off"
Check the Battery Status watch cat /proc/acpi/battery/

Sometimes the remainder of the command is BAT0 or BAT1, sometimes it begins with a "C" Trial and error will get you there. You might end up needing to look in "/sys/class/power_supply/BAT0/status" or some such place.
