RAM loss and windows losing focus?

Asked by Dylan on 2012-08-08

Okay; I recently created a dual boot environment for Windows 7 and Ubuntu 12.04.

In both OS's, system diagnotics report that I have 1.6 GB of RAM; although I have 2 GB installed.

In Ubuntu; I have noticed that while typing the cursor will sometimes jump elsewhere, such as the browser bar or further back/up lines in the field I am typing in. I am using a Logitech USB Mouse on a Compaq laptop; and I would also like to use thedouble-tap to disable my touchpad as I don't use it much anyway.

I am able to point and click with the pad itself, as well as use the left/right buttons; but I cannot double tap the corner area to shut it off.

Any support greatly ppreciated!

Ok, can you give the output of:

If you run the memtest, is the RAM healthy?

Dylan (1disturbed1s) said : #6

How do I perform that?

I've ran a Smart Data check in the disk utility just after installing Ubuntu last night and everything was well with that.

Do I access Memtest in the boot menu or what?

Sorry; I'm very new to Linux based systems.

Hold SHIFT at boot and select the test in Grub menu

Dylan (1disturbed1s) said : #8

There were no errors with that.

(Grub loads automatically for me)

If you use Unity2D session (selectable from login menu), is the system better?

I notice you don't have the proprietary video driver installed. It may help

Dylan (1disturbed1s) said : #11

I noticed a driver-icon notification and it asked to update properitary drivers; but it failed twice. It told me to view the error log; but I found no information from that.

(Everything else is up to date on my system as far as I can tell; I ran and updated yesterday morning before posting here.)

Can you help with this problem?

Provide an answer of your own, or ask Dylan for more information if necessary.
