Enable 3D Mode Unity 12.04

[NikTh]

I don't mean to hijack the thread but what about those of us with hybrid video cards? I have one of the Optimus that uses the Intel for most things but can switch tot he Nvidia when needed (420M) but I can't seem to get Ubuntu setup to do so.

Hi ,
try to use Bumblebee project

further problems will be best to post to a new thread .

Thanks

I'm with the last guy. I have a Geforce GT 520M and get the exact same error message as he does. I also haven't found any thread close to solving this problem yet.

Hello.

I have a new install of 12.04 but, apart from one a few hours, I only have Unity 2d. Nvidia current and nvidia settings have been purged and I have the output below.
Any suggestions about where I should go next would be gratefully received.

Hi!, Peter K Nichol,

Have you run:

unity # or:
unity --reset # or try:
sudo apt-get install --reinstall ubuntu-desktop

If so, with what results? [ Re-boot after each]

Please Post:

 uname -r
cat /etc/lsb-release 
lspci -nnk | grep -iA3 vga
ps ax | grep unity

Chao!, bogan.

Thanks for the reply. It will be a couple of days until I get back to the machine but I will let you know how I get on.

Rather inconclusive results. A few warnings including "this shouldn't happen" and it is still in 2d.

Hi!, Peter K Nicol,

Your Post shows 'unity-2d-shell' running, which is the 2d launcher, and in 12.04 that is not a default, and the unity-3d programs all look normal.

Furthermore the 'unity_support_test' shows 3d supported, but the OpenGL using Gallium/mesa, which implies Nouveau.

Have you got 'nomodeset' in as a boot option?, that could force 'mesa' and degrade graphics.

You also Posted that the nvidia drivers had been purged - they should not have been there in the first place.

So I am thoroughly confused. Did you check that any Nouveau blacklist entry, made for the nvidia driver install, has been removed from /etc/module.d??

I do not know a lot about ATI Radeon video cards & GPU's, but i am surprised to see it using thje 'radeon' kernel module, and not 'fgrlx'.

Googling: "ATI [1002:9644]" & "1043:84c8. AMD Radeon HD 6410D" did not produce anything of obvious significance to me; perhaps it might help you.

Hopefully, someone more knowledgeable in AMd/ATI/Radeon matters will come forward to help.

Chao!, bogan.

Hi!, Peter K Nicol,

Second thoughts:

Where did you get the " this should not happen" messages? and what was 'this' ??

Have you checked if there are other drivers available in 'Additional drivers' ??

Chao!, bogan.

[Peter K Nicol]

Thanks for the help. Again it might be a few days until I can get anything done.
The messages were part of the output from
unity # or:
and
unity --reset # or try:
which, incedentally, both hung.
I will report back next week.

Is the answer in here somewhere or is it part of the same problem?
