No luck with 3D games!

[Dingo]

I just got a new Intel Core 2 Duo E6850 2Gb Ram, 512MB Nvidia GF 8500 GT PCI-E graphics card. Just installed Sabayon 3.4f. Absolutely awsome!!
Unfortunately none of the 3D games open. Sauerbraten, Savage, Second Life etc. They are trying, but then nothing happens.
When I click on Nexuiz the resolution on the screen suddenly goes way down (normal 1680 x 1050) and I loose the mouse cursor. Only way out of this one is rebooting.
It is a bit annoying that I cannot use everything of my new OS. This is also the first time that I have a Nvidia card.
I am still relatively new to Linux and this is the first time that I have installed Sabayon. I have Ubuntu on our other computer. Please do not be too technical.
Many thanks in advance.

Hi there..
The problem is missing use flags.
I quote Wolfden from another topic:

add it to your /etc/make.conf
opengl sdl png gif qt3 qt4 qt3support gtk <---make sure to remove the -gtk

After you added those words to use in make.conf just re-emerge your nvidia drivers and all should be working again

As I said in the previous post I am still a bit new to Linux. Could you please give me a step by step guide? Re-emerge nvidia drivers? I am glad that it is possible to fix this though. Sabayon really is a cool distro. Best looking around. Sorry about the hassle.

To add USE flags to /etc/make.conf do as root :

nano -w /etc/make.conf

then add the use flags in the part that starts with "USE="

Press Control and X, nano will prompt you for saving the changes, say yes if you're done, nano will prompt you to use the same filename, say yes.

then as root do :

emerge --sync

layman -S

emerge nvidia-drivers

Probably will want to reboot after that to make sure the newly-installed driver gets used.

Yes that's it
Sorry i did not write a full explanation..
Also if you wonder what "do as root" means.. you open a command console.. found at the top of favourites on your kicker menu..
Then you write su and then root as username and your chosen password when asked.
Thanx flick also for the help explaining better than i did at first
Hope things will work out for ya

Or you could use the gui- click menu-applications- settings-acceleration manager- aiglx- configure desktop acceleration.

Not at all !!
The issue is missing stuff in a configuration file, and it will NOT help to use acceleration manager. 3.4e and 3.4f are the versions affected.

I found the file.
I am now supposed to add this to the bottom of the file:

opengl sdl png gif qt3 qt4 qt3support gtk

This I do not understand:

<---make sure to remove the -gtk

I cannot see -gtk anywhere.
Sorry for being so thick, I am just a bit worried about breaking the system. I already have re-installed a lot of things lately.
Thanx again, this really is a great community

Hello again
Best to add the words opengl sdl png gif qt3 qt4 qt3support gtk just after the word USE= in the file.
Also if your file does not have any -gtk you can just ignore that. Some has that word apparently, but not all. I could not find it myself
Hope this helps.. Otherwise perhaps it will be fixed by next release "wink wink at Lxnay"

Once again

Sorry, but I do not seem to be able to write the changes into the right spot. Everything always ends up at the beginning. I realize I have to learn a lot and I am starting to feel a bit stupid.
Hope you still got a bit of patience left.
Cheers
