Samsung Galaxy Tab Reset

Merry Christmas, I got you a new toy.  A Samsung
Galaxy Tab.  Cool.  Let’s’ check out Pandora.  Oopps.  Hard crash.  Can’t turn it on or anything.  Had plenty of battery.  No choice but to reset.

Soft reset:
Hold down the Power, Volume Up and Home buttons at the same time.

Release them when you see the startup screen.

Use the Volume Up and Volume Down to choose an option.  There were four of which I remember “system reboot” and “factory reset”.

Push the Home button to confirm.

Ubuntu – various software management commands

While I have not spent much looking, I have yet to find a way to have Ubuntu 10.4 manage the number kernels it keeps after upgrading. I have had to manually remove older kernels to apply updated versions later.

To list your currently install kernels:

From a Terminal session enter the following:
sudo dpkg -l | grep linux-image | more

To remove kernel packages, enter the following:
sudo apt-get remove linux-image-2.6.xx-yy-generic

Note: You can remove multiple installed kernels by just adding them to the list:
sudo apt-get remove linux-image-2.6.xx-yy-generic linux-image-2.6.xx-zz-generic

To list all installed packages:
dpkg --get-selections

To list all files a package contains:
dpkg -L packagename

To install a package:
dpkg -i packagefilename
For example:
dpkg -i somepackage.deb

To list available packages:
apt-cache search –names-only ‘stringtosearch’

To clear apt cache:
apt-get clean

To update your repository list:
apt-get update

To upgrade one software package:
apt-get install –only-upgrade packagefilename

To upgrade all software packages, if one is available:
apt-get upgrade

To disable a service:
update-rc.d servicename disable
