2 issues with ubuntu 12.04 I'm having

[Lithum]

Hi there, I tried getting ubuntu to recognize my NVIDIA GeForce GT 520MX; Optimus card so i could enjoy some 3d effects plus it would boost the overall gaming experiance i would be able to have.

Problem is though when i tried to install a nvidia driver yesterday ubuntu got stuck in 640 x 480 resolution.. after a few hours of annoyance and browsing the forums i finally came across with a solution that i entered into the terminal.

However though it still doesn't solve the overall issue of getting my Nvidia graphics card recognized.

Second issue is that I'm also having trouble getting my wireless to work it will connect to the router but it seems that the router or *something* is preventing a connection. I read the windows wireless drivers may of be help, but I tried that out for it only to fail as well.

If anyone could help me out in solving these issues it would greatly appreciated.

For that optimus card support you have to check and install Bumblebee

http://bumblebee-project.org/install.html#Ubuntu

after install run :

optirun glxgears

or

glxgears

to see the diference

What type of wireless adapter? And are you using Gnome Network Manager to connect?

Not too sure what kinda of adapter i have, and i've had this problem in both gnome and unity i just used the defaults that came with the system .. network connections?

You're probably using Gnome Network Manager then. You could try downloading and using wicd, that's a cross platform one I've used pretty successfully in the past. The only problems I have with it are that it doesn't seem to support VPNs or using multiple wireless network adapters.

First though, can you open a terminal and type

lspci | grep Network

if you have an internal network adapter or

lsusb | grep Network

if you have an external one, then post the output here?

A Google search with those wireless drivers turns up a lot of people having problems. Not good.

Okay - what happens when you connect to your network? It says you're connected but you don't have internet, right? What happens if you type

ping [YOUR ROUTER IP]

when connected to the network? If you're not sure, your router IP is probably either 192.168.1.1 or 192.168.0.1, and can be found by typing

sudo route -n

and looking next to 0.0.0.0 under Gateway.

And what if you type

ping 8.8.4.4

anything?

Yes I get connected to the router, but i dont get an actual internet connection.. anyway heres the outputs

64 bytes from 192.168.2.1: icmp_req=1 ttl=64 time=0.471 ms
64 bytes from 192.168.2.1: icmp_req=2 ttl=64 time=0.496 ms
64 bytes from 192.168.2.1: icmp_req=3 ttl=64 time=0.463 ms

and so on...

when i type ping 8.8.4.4

64 bytes from 8.8.4.4: icmp_req=1 ttl=54 time=42.4 ms
64 bytes from 8.8.4.4: icmp_req=2 ttl=54 time=38.6 ms
64 bytes from 8.8.4.4: icmp_req=3 ttl=54 time=39.3 ms

You are in fact connected to the internet then, your DNS settings or server are probably the problem. Open your web browser and try typing in http://74.125.224.72/

What do you get?

EDIT: Also, right click your network manager icon and select "Connection Information". What does it say next to Primary DNS and Secondary DNS?
