A friend of my asked me to put Ubuntu 12.04 LTS onto his old Dell Latitude D830 Laptop. I installed the OS but I have a few problems.

  1. I have no idea how to install the graphic drivers and set it up so that it auto updates every time the OS is updated, Nvidia Quadro NVM 140M.

  2. I have no idea how to get the wireless card built into the laptop working properly. I have no idea where I could get a similar linux driver for this device.

Can someone help me out?

First of all, I sugest you update your Ask Ubuntu account profile and add your name and picture on it. Name and photo are shown below your question, or whatever you state at Ask Ubuntu, so others can know who they are talking to and also to call and reference you by your name.

I am using Ubuntu 13.10 on a Laptop Dell Latitude D830, just like your friend's, except by the video card (Nvidia) with which I won't be able to help you. However, I guess I've seen something about installation and driver for this device here at Ask Ubuntu.

Concerning the wireless card, try out the following:

1) Do you know the model and chipset of the wireless card? In case you don't, go to 'Software Center', download and run a software called 'Sysinfo' and find out.

2) At 'Software Center' download an other software called 'Synaptic Package Manager'.

3) Using Synaptic search field, look for 'bcmwl-kernel-source' package and check if it is installed on your computer (if installed, a small box on the left side of the package name is turned green). If it's installed, your case might be like mine. I've got a Dell Wireless 1390 WLAN Minicard (chipset Broadcom BCM 4311 802.11 b/g). It may vary among the same laptop model.

4) Look for the package 'linux-firmware-nonfree' and verify if it is installed. Click on the package and read it's properties to know if your device model is compatible.

5) Look for the package 'firmware-b43-installer' and verify if it is installed. Click on the package and read it's properties to know if your device model is compatible.

6) If 3 is installed but 4 and 5 are not installed but are compatible with your device, you probably have at least a hardware similar to mine. Right click on the package and "remove completely" the number 3 and "install" numbers 4 and 5.

7) Reboot your computer.

After reboot, the wireless light should be turned on and the wi-fi should be working automatically. Check for the Wi-Fi / Network indicator on the up-right corner of your screen, click with the right button and choose the network to connect, preferences, etc.

In case your answers on steps 3, 4 and 5, didn't match mine and or your chipset wasn't on the list of capatible models for packages 4 and 5, the procedures decribed here might not be appropriate for your case.

Any way, if you make a try and it doesn't work, you can still revert the install/uninstall realized and roll back the system.

Don't forget to return here and give us a feedback.

Cheers!

Answer update: apparently, at least with Ubuntu 14.04, it's not necessary to install the package 'linux-firmware-nonfree'. Removing completely 'bcmwl-kernel-source' and installing 'b43-fwcutter' and it's dependant 'firmware-b43-installer' is enough to fix the problem. –  Felipe G. Maia Jul 22 at 15:15
