Mouse stops working at random times.
 

Hi, I just installed and are new to Ubuntu. I have a problem with the os is constantly ignoring my mouse after about 5mins of doing whatever, then I have to restart just to get it to work again. (btw im using a Dell USB mouse if you need to know...)

Try running "lsusb" when it is working to see the mouse entry
when all is well. The next time the mouse stops working, run
it again and see if the entry has changed.

If the entry disappears, it's likely to be hardware related.
Could be a bad mouse, a bad cable, a bad USB port, etc. If
the entry is still there, it will take some troubleshooting.

You can try plugging it into another USB port and see if the
same issue happens.

I already know it isnt a hardware isssue because I still have windows xp installed and does not show any problem with the mouse >,>
It only seems to happen when I use the ubuntu os....

It might be a problem with the graphics card. Is it an nvidia card? I had a similar problem when using the live cd, the screen froze after about 5 mins of use (with the screen not updating it appears that the mouse does not move). Do any key commands still work?

If so, what version of Nvidia driver are you using?

Actually it did freeze during the live cd (well that auto d/l and install torrent)
At first i thought it was forcing me to watch the whole slide show slowly..*facedesk*

I can still (at most times) use my keyboard so i just ctrl+alt+delete > restart :l

I'm using a Nivida GeForce 6150 LE

It sounds like a similar problem. I think the following sorted my problem out.

There used to be a file called /etc/X11/xorg.conf that was used in Ubuntu to hold information about the x windows. This is no longer needed, however Nvidia driver still needs this file.

Firstly make sure you have installed the Nvidia package.

The plan being this should create the missing file xorg.conf. Then the nvidia driver can write to it.

You can then check the nvidia settings in System>Administration>Nvidia X server settings> and System>administration>hardwaredrivers

However this often a difficult problem, as you can see from the number of other thread on the issue, and there is a chance doing the above might break it.
