I have a similar issue with a very closer computer if not the same. in my case I am using a VOSTRO 3300 hybrid with Intel and Nvidia video cards.
eduardo@node:~$ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18) 01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 310M] (rev a2) running over Ubuntu 11 but with the default video driver -- in another test after to have formatted and installed again Ubuntu 11 I had tried the Nvidia Experimental driver loaded in property driver but it doens't work too. so for this new test I didn't download the Nvidia Experimental 3D driver and just keep the default driver: eduardo@node:~$ uname -a Linux node 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux eduardo@node:~$ lsmod |grep video uvcvideo 72195 0 video 19438 2 nouveau,i915 videodev 82052 1 uvcvideo v4l2_compat_ioctl32 17078 1 videodev Looks like the 3D effects are enabled by default as I am able to see the new menu in Unity on the left side but when I connect my external monitor (Samsung 23" LCD) the image is all trembling. I tried to change the resolutions for all combinations as possible but with no successful. please let me know if you need any other info I will glad to provide it.
