Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have a small problem.
I have an Asus with a Nvidia GT630m k55vm and I want to install Ubuntu from a USB.

I select try without installing, and it works perfectly with the effects of Unity 3D mode, but when I install and run Ubuntu on the system, it doesn't work in 3D mode.

It starts up in 2D mode and the effects do not appear. What could I have done wrong?


Thanks for the answer. There is no driver available. But I don't understand why if it works well on the live cd, it doesn't work when ubuntu is completly installed.

Thank you very much!

Did you install your video drivers –  Max Tither Aug 19 '12 at 23:31

Did you install the proprietary Nvidia drivers?

In theory, shortly after installation, Ubuntu should notify you that "restricted drivers are available".

Otherwise, go to System settings -> Additional drivers. It should show you Nvidia drivers available for download. Select it, agree to the terms if necessary, install them and restart.

Ubuntu is not allowed to distribute these drivers; therefore, they have to be installed explicitly by the user.

Since, as you write, the drivers are not available from the Ubuntu repository (yet), you could install the drivers directly from the Nvidia web site. Apparently, it explicitly supports GT 630M.

I have no idea why it works in the live system. Of course, you can find out what driver and in which version is used by the X. You will find this information in the Xorg log files in /var/log. For example, one of my systems shows the following information:

(II) LoadModule: "intel"
(II) Loading /usr/lib/xorg/modules/drivers/intel_drv.so
(II) Module intel: vendor="X.Org Foundation"
        compiled for 1.7.6, module version = 2.9.1
        Module class: X.Org Video Driver
        ABI class: X.Org Video Driver, version 6.0
(II) intel: Driver for Intel Integrated Graphics Chipsets: i810,
        i810-dc100, i810e, i815, i830M, 845G, 852GM/855GM, 865G, 915G,
        E7221 (i915), 915GM, 945G, 945GM, 945GME, Pineview GM, Pineview G,
        965G, G35, 965Q, 946GZ, 965GM, 965GME/GLE, G33, Q35, Q33, GM45,
        4 Series, G45/G43, Q45/Q43, G41, B43, Clarkdale, Arrandale

The Xorg drivers are in packages with names like xserver-xorg-video-name, so one can find names and versions of the installed drivers as follows:

dpkg -l | grep xserver-xorg-video

That way you can compare the system from the Live CD with the installed system.

I have checked the drivers on the Live CD and on the installed system and they are the same drivers, this is the result

Do I try to install the drivers from the nvidia website?

Thanks
