GUI hangs After installing NVidia driver

[noyanculum]

Hello guys,

This is a follow of this thread: http://ubuntuforums.org/showthread.php?t=2193423

I use Ubuntu 12.04 LTS. 1 week ago I installed a Nvidia Geforce GT 420 graphics card to my pc. Within this installation, I installed a lot of critical packages: kernel, xorg, lib32 etc... Before that day everything have been working quite well. I could connect to the internet with no problem.

MY ISSUE: But since the day I installed Nvidia card, my wireless connection hangs permanently. When I launch Firefox (or Chrome, Opera), I can visit only 2-3 webpages. 1 minute later the connection hangs. I can not connect anymore. 4-5 minutes later, terminal and file manager hang also. Then I have to restart the computer by a hard shutdown.

AN ADDITIONAL TEST: As a small test, I launch first the terminal window and I make some network operations (ping, traceroute, apt-get update..) via terminal during 15 minutes. Nothing hangs, everything work quite well. Then I launch the Firefox (or Chrome, Opera) and 1 minutes later the wireless connection hangs permanently again.

THE OPINION OF NETWORKING GUYS: I posted this problem first on Networking section of this forum. You can see the discussion on the link I gave you above. After some system analyzes, the networking guys decided that the problem is a Xorg related issue. The final conclusion of the old thread is: "Could be a kernel/driver or services crash due to a misbehaving driver or setting. This driver can be anythin, including wireless. But since the same driver works nicely before changing X configuration, I believe it is almost certainly related to an Xorg or Nvidia driver bug. I believe a misconfigured Xorg can cause troubles beyond imagination."


Could someone please lead me how to solve the issue? Is it a Xserver Xorg related issue? What I have to do to find the reason of the problem?

Thanks in advance.

Use nano or Gedit and perhaps post the output of this for starters:

nano /etc/X11/xorg.conf

Also:

sudo lshw -C video

But now it sounds specific to Firefox or Chrome killing the network. Is there a particular page that kills it or it just hangs after a minute? Are you using the same home page on both browsers? Just a thought ...

I don't have a specific home page. In Firefox, I use a blank page. In Chrome, it is Google. In Opera, it is the speed dial (kind of a blank page) page.

Here the outputs:
