ubuntu 12.04 LTS freezes in unity after resuming from Lock, Suspend, and Hibernate

[acerbuntu]

Hi guys,

I am running ubuntu 12.04LTS and Iam having system freeze problems every time when I resume from lock, suspend, and hibernate.

This problem comes up only in unity (ubuntu) desktop not in unity 2D (ubuntu 2D) or Gnome Classic.

I don't have complete idea about it, but when click on ubuntu logo in my login box I can see 4 options such as Ubuntu, Ubuntu 2D, Gnome Classic and Gnome Classic (No effects).
My System freezes when I use it in Ubuntu environment.

Is Ubuntu environment unity 3D?

Please help.

Thanks in Advance.

Hi,

Copy and paste and run -

/usr/lib/nux/unity_test -p

Results will show if your hardware supports Unity.

Cheers -

Edit - yes Unity is 3D

Tried in 3D...No luck

bash: /usr/lib/nux/unity_test: No such file or directory

Sorry I forgot to mention that I am using integrated graphics (HD 3000) not the NVidia.

Do the graphics need to be Nvidia? If so I don't have any idea how to make Nvidia work!

Specs look pretty good to me but I'm no expert.

It may have something to do with your graphics card.

Hi-

You need to enter a space and then -p after test

[BlinkinCat]

It may be easier to download a terminal from Software Center

I have integrated graphics and Unity 12.04 is fine for me.
