How To Install Itunes On Linux Mint 16 Petra
Having a dedicated graphics processing unit ( GPU or graphics card ), boosts graphics performance significantly, especially when playing 3d games. Nvidia GPUs are very popular on desktop computers and they work very well on linux, as drivers are available from Nvidia.It is necessary to install the right drivers to ensure proper utilisation GPU. Otherwise the performance would be limited, or totally unused.
Nouveau - the default driverFor Nvidia GPUs, the driver becomes active by default. Nouveau is the open source driver for Nvidia GPUs.Check it with the lspci command. $ lspci -vnn grep VGA -A 1201:00.0 VGA compatible controller 0300: NVIDIA Corporation GT218 GeForce 210 10de:0a65 (rev a2) (prog-if 00 VGA controller)Subsystem: ZOTAC International (MCO) Ltd.

However with the Nouveau driver the gpu cannot perform to its full potential and features like hardware 3d acceleration would be unavailable or limited.The official nvidia drivers would make the gpu deliver its full performance. Testing graphics performanceIt might be interesting to compare the graphics performance with different drivers and to ensure that the gpu is indeed performing well. For this we use 2 little utilities called glmark2 and glxgears.The glxgears command would popup a small window with an animation of rotating gears.
It would then print out the fps every 5 seconds on the terminal. $ vblankmode=0 glxgearsATTENTION: default value of option vblankmode overridden by environment.4589 frames in 5.0 seconds = 917.740 FPS4714 frames in 5.0 seconds = 942.641 FPS4717 frames in 5.0 seconds = 943.335 FPS4718 frames in 5.0 seconds = 943.558 FPS4713 frames in 5.0 seconds = 942.536 FPS.Note down the fps, which is around 940 in this case. Next run the glmark2 command, and let it complete all tests and at the end it would show a score. $ glmark2glmark2 2012.08OpenGL InformationGLVENDOR: nouveauGLRENDERER: Gallium 0.4 on NVA8GLVERSION: 3.0 Mesa 9.2.1build use-vbo=false: FPS: 420 FrameTime: 2.381 msbuild use-vbo=true: FPS: 430 FrameTime: 2.326 ms. OUTPUT TRUNCATED.glmark2 Score: 336So with the Nouveau drivers, the glmark score is 336 and glxgears max FPS is around 940. Setup Nvidia proprietory driversNow install the Nvidia proprietory drivers. The Nvidia drivers are available in the Ubuntu repositories but they are mostly out of date.

The drivers are named like nvidia-331, nvidia-319, nvidia-304 and so on. Each driver supports a different set of graphics card.So first of all find the right driver for your GPU1. Check the graphics card modelCheck the model of your GPU chipset with the lspci command. $ lspci -vnn grep VGA -A 1201:00.0 VGA compatible controller 0300: NVIDIA Corporation GT218 GeForce 210 10de:0a65 (rev a2) (prog-if 00 VGA controller).The model of the graphics chipset is, NVIDIA Corporation GT218 GeForce 210. Now we need to find the right driver for this card.2. Find the correct driver from nvidia siteGo to and select your model and click Search.On the next page, you would get all details about the driver, version, release date, supported chipsets and further information about how to install it.For the above GeForce 210 card, it showed 331.67 as the correct driver which can be downloaded from the website as.bin file. However we shall install the drivers from ppa to make things easier.3.
Configure the ubuntu-x-swat PPAThe ppa provides updated versions of nvidia drivers for ubuntu. $ sudo add-apt-repository ppa:ubuntu-x-swat/x-updates -y$ sudo apt-get updateIf you are looking for the very latest drivers then try another ppa called. $ sudo add-apt-repository ppa:xorg-edgers/ppa -y$ sudo apt-get updateAfter adding the new ppas, you can check the new drivers and their versions by running To list the Nvidia drivers available in the repository search using the aptitude command $ aptitude versions ^nvidiaOr open the Synaptic Package manager and search for packages named nvidia. Now that the ppas are setup, we are ready to install the driver.4. Install the driver from Driver ManagerWe shall use the Driver Manager to install and activate the driver. Go to System Settings Driver Manager (Under Administration)Select the driver (nvidia-331) and click Apply.
It would then download the necessary packages for the selected driver, install it and configure it. Once the Driver Manager finishes, restart the machine for the new drivers to take effect.
Verify the new driverAfter the reboot, check the graphics driver using the lspci command again. $ lspci -vnn grep VGA -A 1201:00.0 VGA compatible controller 0300: NVIDIA Corporation GT218 GeForce 210 10de:0a65 (rev a2) (prog-if 00 VGA controller)Subsystem: ZOTAC International (MCO) Ltd. BruceThe list of drivers didn’t show up in the driver manager.
Yet after I ran the $ aptitude versions ^nvidia command I got a whole list of drivers.The latest driver for my card is apparently version 375.39 but the only driver showing up in the manager is version 367.57 and the nouveau(open-source) driver.Did everyone get this message as part of $ sudo add-apt-repository ppa:xorg-edgers/ppa -y. WARNING: Do not use this PPA with enabled HWE stack.Be sure to revert this PPA before doing a release upgrade or the upgrade will not succeed. To revert to official packages, install the ppa-purge package and run “sudo ppa-purge xorg-edgers”.Help please?
