Troubleshooting

Just a beginner with ubuntu 11.10 (on a toshiba tecra 8200)and was frustrated till I found out about using KDE and now I am making head way.
Problem is today it installed about 200 updates and now the mouse button (the same thing as a touch pad on newer models) in the center of the key board doesn't work (this is the only thing wrong so far) but everything works fine with an external mouse pluged in.
Does anyone have advice where to go or what to do to correct this? I can fine the mouse software but it only controls how the external mouse works not the key board button(same thing as the touch pad on newer models).
Thank you everyone for the past help.

I'm using Ubuntu 11.04. My panels both top and bottom have times when they show solid system colors and other times when they become transparent or partially transparent in the middle allowing desktop to be visible. Is this some kind of bug, worm, or Trojan, etc...?

I have UBUNTU 11.10 desktop version on my comp and i am trying to install a driver for my nvidia gtx 560 ti video card. When i go to additional drivers, click NVIDIA accelerated graphics driver, and click activate, it downloads half way, and then i get this error message:
Sorry, installation of this driver failed.

Please have a look at the log file for details: /var/log/jockey.log

When i go to jockey.log it says this:

What command must I use to get my MP3 player recognised by the media player (it's a Jensen)

I found that I again had the bug "getdeb.list.bck in sources.list.d". I don't know how to change or remove the files in the sources list. It's not a crucial issue, but it is quite irritating each time you do an update of sources to get in the terminal:Ignoring file 'getdeb.list.bck' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension. I would greatly appreciate any help and suggestions. Thanks.

I reinstall Ubuntu 11.04,and when try to reinstall the BURG,I cant, same when I Try to run the software center ,and install AWN, and same when I Try to update my system.I got the same error :An unresolvable problem occurred while initializing the package information.

Please report this bug against the 'update-manager' package and include the following error message:

'E:Malformed line 2 in source list /etc/apt/sources.list (dist parse)'

Any idea how to resolve this,Thanks .

I recently upgraded my computer system to include the new A75 fusion system. I used Gigabyte's GA-A75M-UD2H. Everything works fine except the sound. I don't use windows. I've used a lot of distros and the only one that works correctly is Kubuntu 11.10 Alpha2. This is a clean install and no updates. I do not know what will happen down the road. I've contacted tech support three time, and each time have been told to test it using Windose. They don't seem to care that I don't use windose. That is how they left the problem. Needless to say I won't buy gigabyte again. I'm thinking of returning this and going Asus. Just an FYI
