[SOLVED] Mouse Trouble

tech949 · 10-05-2010, 02:56 PM

I just installed Ubuntu 10.10 on my HP Pavilion a320n computer with a ps2 mouse and the mouse pointer points with the bottom of the mouse and not the upper tip of the point. It does the same thing with Ubuntu 10.04.1. In Windows 7 and XP the mouse is normal. I don't know how I could adjust it or is this just a bug in the OS?

Any help would be greatly appreciated.

try changing the mouse icon in appearance settings, applying, and changing it back

Another problem is that the taskbar, at the bottom of the screen, is showing less than 1/2 (of the top). I adjusted the monitor. I moved it up but it's still the same with black space below.

I tried your suggestion but it didn't help. I installed Ubuntu 10.10 on my other computers, Hp Pavilion a365c and Aspire 4520 laptop, and ALL the problems are gone.

that sounds like a video driver problem. Find your model video card and find the linux drivers for that model on the manufacturer website and install those, making sure you have all the necessary dependencies.

If I could figure out how to install the video card driver that would be great. After I downloaded the video driver I opened a terminal and typed "sudo apt-get install /home/NVIDIA-Linux-x86-256.53.run" but I got error messages. It looked like it was beginning to make some progress then "unable to locate package..." "couldn't find any package by regex..."

I did some research and almost have the video card installed. After booting Ubuntu in recovery mode "drop to root shell prompt" and change to runlevel 3, I am able to start the Nvidia driver install by using "sudo sh NVIDIA-Linux...run", but I get an error messages "distribution provided pre-install script failed, Continue anyway?" and I say YES. "Unable to load the kernel module nvidia.ko" "Installation has failed". Any thoughts?

installing a .run file is completely different from packages. here is what you should run AS ROOT! in regular mode not recovery mode.

Code:

# chmod 755 <driver file name.run>
# ./<driver-file-name.run>

from there you should be able to just follow the on screen prompt.
just fyi, apt-get install works with the debian repositories and is not going to work with bootstrap installs, scripts, or precompiled binaries. reading up on how to install things using these methods and on some of the syntax of linux will greatly help you.

The only way I know how to logon as root is to restart the computer in recovery mode, and choose "drop down to root shell prompt".

The only way I know how to logon as root is to restart the computer in recovery mode, and choose "drop down to root shell prompt". When I run the NVIDIA driver update the way you told me, I get messages "must quit x-server" and "change from run level 1 to run level 3". Even after quitting x-server and changing to run level 3 I still get errors "script failed" and it won't finish installing.

ok type this in

Code:

$ sudo chmod 755 ./<nvidia-driver.run>
$ sudo ./<nvidia-driver.run>

If it asks for a password just type in your normal password. sudo is how you can run commands as root without actually being root.

I tried that too with the same (error messages) results. I'm ready to give up and just take it off this computer. I installed Ubuntu on my other computer with no problems.

make sure linux headers are installed

Code:

$ sudo apt-get install linux-headers-$(uname -r)

also try this

Code:

$ sudo apt-get install module-assistant
$ m-a

then choose the 'prepare' option, then after it installs exit and then go back and run your .run file.
this makes sure all the dependencies are installed
