You can manually install the NVIDIA proprietary drivers for the GT 730 from the xorg-edgers PPA on 14.04: Open a terminal and type: sudo add-apt-repository ppa:xorg-edgers/ppa sudo apt-get update sudo apt-get install nvidia-340

Even if this a little bit late but I have fallen into the same issue. If your nvidia card has an hexadecimal PCI-Bus number (maybe 0a:00:0) here might be solution (at least for me). https://github.com/Bumblebee-Project/Bumblebee/issues/573 Find out where your bumblebeed binary is and then: sudo cp /usr/sbin/bumblebeed{,.orig} sudo sed -i ...

If you have it installed, you can also use nvidia-smi which provides even more information for NVIDIA GPUs (this is, after all, what they use in the page you linked): $ nvidia-smi Mon Sep 15 16:02:31 2014 +------------------------------------------------------+ | NVIDIA-SMI 340.32 Driver Version: 340.32 | ...

Most can be found out by using the lspci command in conjunction with grep. Most GPU's are listed with model name with the following command: lspci | grep VGA


2

please update your PCI ID database with: sudo update-pciids And use the following command in your terminal: lspci -nn | grep '\[03' You will see the model name of your graphic card. If it's ambiguous, you could search the PCI ID (something like [10de:11bc]) on the Internet for the corrent model name.

You might try to restore the original /usr/lib/xorg/modules/extensions/libglx.so from xserver-xorg-core . That's what I did in a similar situation. Here's how: First confirm that it has indeed been replaced by the nvidia install: debsums xserver-xorg-core | grep libglx.so If it shows FAILED, it means that it has actually been replaced, and you could try ...

I was having similar problems with Chromium (and Chrome when I downloaded that). It turns out that WebGL is still classed as experimental, and so it's switched off by default for us. To turn it on enter the following address into the address bar: chrome://flags and press enter (or refresh). Then select the 'Enable' link under Override software ...

Firts: In order to allow dual booting of Ubuntu with other operating systems, Uefi Secure Boot needs to be disabled in the system firmware. The board firmware should offer a boot menu, although on some boards this may mean you need to boot into the MS OS Win 8 and cycle through various menus to turn off Uefi Secure Boot and then reboot. You are going to ...

It sounds like your graphics card does not have sufficient 3D capabilities to run the Unity3D interface fluently. Is it an old card? You might want to use a different desktop environment once you finished updating. Like XFCE or LXDE.

I think I found the fix. Source: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1314367/comments/22 so far so good. I'll update this if it starts flickering again. For those that are wondering, you need to install compizconfig-settings-manager first from terminal. sudo apt-get install compizconfig-settings-manager Open it and go to workarounds and ...

New kernel for 14.04 uses a special video patch for nvidia video drivers to work. I encountered similar issues while trying to install the genuine nvidia driver from nvidia.com (after a fresh install of Ubuntu 14.04!!!). So, you need to either perform a fresh install of Ubuntu 14.04 after you backup your home user data because the kernel for 14.04 is simply ...

I was having the same problem with nVidia driver 340.32 (on Ubuntu 14.04). After reading this thread, I rolled the video driver back to 331.79, and so far haven't noticed any flickering.

You can install the nvidia driver from ubuntu software-center. Open ubuntu software-center, click edit and select software sources. Click on Aditional Drivers and from there you can select the proprietary driver from the list of drivers. The most stable version is the one marked "tested".

My system was so badly beaten up that I decided to upgrade to a still supported version, 12.04, and so after cloning the disk with clonezilla and pressing upgrade (and a lot of waiting), I was happy to see that nothing I cared about was broken, and the video problem was fixed after installing the recommended nvidia drivers. In other words, taking the plunge ...

General rule: when upgrading manually installed PPA's need to be disabled. The system will do this for you while upgrading. But from topics on AU it seems that this sometimes causes problems. Mosttimes (but not always) you can re-use a PPA in a new release so I would 1st try to track down those PPA's and see if there are versions for the new release (be it ...

Using information from the LaunchPad link above and this link on installing/re-installing Nvidia Primus, I was able to re-implement my external monitors.

I'm the OP of the askubuntu question linked in the bug.

First, check that your drivers are up to date running sudo apt-get update && apt-get upgrade. If this does not help, you can manually test the drivers in System settings -> Additional drivers. There, you should see a list of video drivers, both open source and closed source. Try with them to see which one works. Sometimes the closed source one is ...

I've solved this, BUT there is one problem occasionally the fans will run full blast upon reboot of Ubuntu. As of now I have no fix for that, you have to power off and power on computer, but here are the steps anyway. Install Nvidia Optimus support or bumblebee from the Ubuntu Software Center. Make sure you get the optional support for proprietary drivers ...

For CUDA-6.5 I followed this tutorial: sudo dpkg -i cuda-repo-ubuntu1404_6.5-14_amd64.deb sudo apt-get update sudo apt-get install cuda It worked on a fresh 14.04.1 install with my GTX 750ti. It installs the nvidia-340 driver. deviceQuery ran properly after I compiled it.

The drivers available via additional drivers are focused on stability and have been tested to assure it. You can still download and install the the latest drivers from nvidia's site and install them yourself.

If you are using a NVIDIA binary driver (you can check by searching for the Additional Drivers program and looking at which driver is selected), then you can use the Nvidia X server settings to change which gpu is used. To launch the Nvidia X server settings, either search for "Nvidia" in the dock or launch the program from the terminal using ...

Trying it can't do any harm. Use the following command before and after the switch. >ou should see a drop/rise in mW being used: # grep rate /proc/acpi/battery/BAT0/state switch off your NVIDIA card using # echo OFF > /sys/kernel/debug/vgaswitcheroo/switch If your laptop now uses less mW, then you get a longer battery life.

I think this wrapper script is one way to make it work: Create the folder bin in your home directory, if it's not there already, and put a file named skype there with this contents: #!/bin/sh export LD_PRELOAD="/usr/lib/i386-linux-gnu/mesa/libGL.so.1 $LD_PRELOAD" exec /usr/bin/skype "$@" Make the file executable with: chmod +x ~/bin/skype If you ...

Remove the package you installed from terminal, then reboot. Open up the Additional Drivers dialog. Look for it in the applications menu, I believe under either System or Settings. Once that finishes searching, it should come up with a window. If multiple drivers are listed, select and activate the one that says [Recommended] next to its name in the list. ...

is it okay if I went on using a virtual machine for development or will it be difficult, slow and has lots of drawbacks? For development you will not really notice the difference.

It seems to be a problem with Optimus. I tried bumblebee as well as prime without any luck. However, going into my BIOS and switching from Optimus to Discrete Graphics (only running the nvidia card), the nvidia driver is finally successfully loaded. One question persists: Who or what is messing with the alternatives? It seems to happen everytime I log out. ...

The installation with the live CD is pretty demanding for an old computer. How much ram memory do you have? I would also suggest you to try lubuntu, as low weight version of ubuntu.

Same here. After some trial and error, downgrading ubuntu-drivers-common to 0.2.91.5 worked for me. Possibly reinstalling nvidia drivers (purge, then install) after this downgrade might be necessary.

If the drivers available through Ubuntu don't work correctly, you could try finding your driver on Nvidia's official Unix/Linux driver's page.

Can you clarify that following questions: Did you have installed the NVIDIA card after installing Ubuntu, e.g This card was not present when you were installing Ubuntu? Did you have removed or disabled and then re-installed the card after installing Ubuntu?


0

Because there is not an official answer to this question (even thought there are about 10 in the comments), I will tell you your problem. The default nVidia driver that comes with ubuntu (nouveau) is an ingenious piece of junk. If you install the proprietary drivers for you nVidia card, your computer will stop freezing.

Check that you have the restricted driver installed for your system. Go to settings and click on Restricted drivers and select one of the options for your Nvidia card. I have a similar card and found the recommended and tested driver (nvidia-331 I belive) worked well.

I could find a few complaints about the 311 drivers online.. http://ubuntuforums.org/showthread.php?t=2220827 I would recommend you try the 304 and 311 both for a few days each. In the end you would know which one to chose. My personal experience says that the x-org graphic drivers use a lot more power and produce too much heat. Also the drivers with ...

The first has been tested and so is probably most stable.

And suddently it hit me, scaling factor! I set my scaling-factor to 1 which it fixes: gsettings set org.gnome.desktop.interface scaling-factor 1 That fixed it! After that command, only my titles where still too big. But a reboot fixed that too.
