Hello first of all and sorry if my english is hard to understand hehe

I've been using Ubuntu since 9.04 and I used the 3d effects. But since the 9.10 version, the drivers stop working. I have a Nvidia GeForce 5200fx and everytime I download and install the driver the resolution changes to 640x480 and I can't change it to 1024x768 again. I tried everything, even using 3d acceleration with nouveau drivers (in this case, my resolution doesn't change, but anyway I can't use the 3d effects). I know that my video card is very old, but is there a way to make it work?

Please specify what version of Ubuntu you're using now. – Jorge Castro Oct 14 '10 at 19:17
I'm using Ubuntu 10.10 "Maverick Merkkat" – Kenichi Oct 14 '10 at 20:12

Nouveau does not yet have 3D accelleration for nvidia video cards. It should have it within a few months, I think. At this time, those of us with Nvidia video must use the hardware drivers to enable 3D.

Which driver version did you install? the Ubuntu and Nvidia developer recommends nvidia-96 for legacy device.

Btw, can you show some last line your Xorg.log. You can see it in System > Adminstration > Log file Viewer.

I use the latest avaible version, I download it from the nvidia website, I don't know wich version is it – Kenichi Oct 14 '10 at 19:29 do not use the installer from the Ubuntu,. but that's okay, no problem, I also use a driver that I downloaded directly on the Nvidia site. maybe this link can help you : try do download the 96 version. or 173 version – squallbayu Oct 14 '10 at 19:42
Hmm I'm trying to install the driver but I get this error: ERROR: Unable to determine the version of the kernel sources located in '/lib/modules/2.6.35-22-generic/build' ... – Kenichi Oct 14 '10 at 20:00
seems nvidia installer does not find its kernel source. try to install the kernel-source, sudo apt-get install kernel-source. and probably ypu need to install build-essential, sudo apt-get install build-essential – squallbayu Oct 14 '10 at 20:05
I already installed build-essentials, but now when I try to install kernel-source it says that there's no candidate for install. Maybe Ubuntu doesn't like me :( – Kenichi Oct 14 '10 at 20:10
