Buying a known-working card is a much better idea, specially if you want access point (AP) mode. In general, the Intel cards are very good. http://wireless.kernel.org/en/users/Drivers/iwlwifi This is a very valuable wiki which details which devices /drivers work, and in which kernel they were introduced. http://wireless.kernel.org/en/users

While using the proprietary driver (as indicated in Hatoru's response) will definitely increase the performance, it will also increase the energy consumption (and therefore decrease the battery life). So, if you want to get maximum performance for applications that require it, and maximise the battery life for the rest, the only option as of now is to use ...

Your video card drivers version should be 340.46. I am sure you can open nviida-settings and check out version, and also adjust all related power-management fields in nvidia-settings. In Kubuntu default power management, make sure you check your settings for all of the 3 sections present in there, namely AC POWER, ON BATTERY, ON LOW BATTERY. Disable Dim ...

OK.. all I needed to do was rebuild the driver for iwlwifi using the backport I installed the ath9k with for the external wifi using the tutorial from the link in my original post. At the location of backport folder (in my case cd /home/sl43/backports-3.16-1): make defconfig-iwlwifi make sudo make install sudo modprobe iwlwifi sudo reboot David thank ...

While this is off topic… PCI Express … is a bus interface for very high throughput, very low latency communication between internal and more recently peripheral computer hardware components. Ethernet … is a physical network interface for high throughput, low latency communication between computers in a local area network. It is not restricted to ...

PCIe is used to communicate with your local network card. The actual network card uses the ethernet protocol to communicate with external network devices. These protocols can also be used within the OS to emulate such devices as well. Here is an extremely basic graphical depiction that I put together for you: Additionally, please note that ethernet is ...

I suggest you run, in a terminal: sudo lshw -C network Find the driver for the internal (Broadcom?) device. Then unload and blacklist its driver. lshw will report, for Broadcom devices, either 'driver=wl0' or 'driver=b43-pci-bridge.' The relevant drivers to be blacklisted are wl or b43. Assuming it is wl, for example: sudo -i modprobe -r wl echo ...

The GeForce GT 610 graphics card can use either the NVIDIA proprietary driver or the Nouveau open source driver. If you are replacing an old Nvidia graphics card with a new Nvidia graphics card it should work with the existing graphics card driver, otherwise uninstall the existing graphics card driver before you put in the new graphics card, then after you ...

HID devices should be auto detected upon startup is it a special mouse with extra functions? if so you may need to. sudo apt-get install qjoypad sudo qjoypad --notray map extra keys

Ubuntu 14.04 runs on kernel version 3.13, but the driver for your mouse was only added to later kernels as per bug report #1316768 (note the same USB device ID 04d9:a070). You can install a newer kernel as described in Kernel/MainlineBuilds or in this case more simply with the package linux-generic-lts-utopic from the Canonical Kernel Team PPA: sudo ...

After researching this, I can't find any terminal command that would display the maximum resolution supported by the graphics card. The easiest way to find out is to go to the manufacturer's website. As listed here, under specs, an AMD Radeon HD 7750 graphics card supports a max resolution of 4096x2160 @ 60 Hz per display, so you should be able to upgrade ...

Boot your computer. After it is started, swicth to TTY1 by pressing Ctrl+Alt+F1 Log in using your normal username and password. run this command to remove the drivers sudo apt-get purge "fglrx.*" "fglrx-amdcccle.*" run sudo rm /etc/X11/xorg.conf to delete the x.org configuration file. run sudo apt-get install --reinstall xserver-xorg-core ...
