First, lets get Ubuntu to a 'clean' state, without any nvidia drivers installed: sudo apt-get purge $(dpkg -l | awk '$2~/nvidia/ {print $2}') Next, let's remove the x-server error - follow this answer. You can install the latest NVIDIA drivers by adding their new PPA to your system. To do so: sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt-get ...

Minecraft doesn't use the GPU for most of its calculations, instead relying solely on the CPU. This results in some pretty trash performance. But, since these calculations are hard coded into the game, there really is no was to change them, and completely change the component that the game is run on. Doing so would require them to rewrite the entire game.

3rd party drivers can be tricky with Ubuntu, but I have had quite a bit of success. NOTE: At least in my case, if you do a system update (one that requires authorization) you'll have to re-install the drivers. Pain in the butt, but it could be worse. Check this link out

ubuntu is getting good at bundling vendor graphics drivers so having to download and install manually is not necessarily the go to solution. Try this : System Settings -> Software & Updates -> Additional Drivers give it time to do its probes/lookups and it will respond with list of pre-loaded drivers from which you can pick an Nvidia if you ...

I have managed to succeed in my efforts to get this undoubtedly exotic setup to work as I want it too. After a reinstall of Ubuntu, the problems with installed guest additions for the natively booted system disappeared. The only remaining problem was being unable to login into the virtual machine desktop with fglrx drivers installed. Although the kernel ...

First, try to see if any other games apart from Unturned don't work (Unturned is a dodgy game on Linux) If that's the case, reinstall Steam, so you have a fresh new version of the library.

Let me tell you this. I have tried even more than you have, I have even visited Linux forums and requeted for support, searched entire internet, asked dozens of people in IT and I never got it work...Same thing. I have NVIDIA GeForce GTX 970 graphic card and it looks like our card can't seem to be able to communicate well with Linux system. I have tried ...

looking on bugs.launchpad.net i see that your card is afflicted by a bug since driver version 331 https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1408567 take a look to the thread , is very similar to your situation

As mentioned in the comments, the solution is to remove the .deb file installed from the Steam website and do sudo apt-get install steam as it automatically installs the required libraries and packages required for the proper functioning of Steam. Edit : Check out this answer to fix the Integer parameter error that throws up.

BINGO! I think I just found a clue on this issue -- This should be reported to the LibreOffice developers and I'll try to figure out how to do that as well: I noticed that if I logged-out of my account then re-logged back in, the problem would immediately go away (ie, menus operating normally). I was shocked to see this, as I've never seen it work correctly ...

This is actually for problems with the battle.net launcher, but maybe it will help you as well to start with OpenGL? Unsure if it then changes launching Hearthstone as well...: https://www.reddit.com/r/linux_gaming/comments/32u25q/battlenet_on_wine_not_working/cqempxt

If you're running Ubuntu on a Chromebook with crouton, the only one of the answers that will work is going to chrome://gpu in the Chrome browser.

Try setting the nomodeset kernel option after installing the driver. A good tutorial for Ubunutu for that would be here.

Based on your query in http://ubuntuforums.org/showthread.php?t=2291771 and the answers there, what you are asking for is not possible. From the forum: From my understanding of Nvidia Optimus technology I do not think it is possible. The purpose of Optimus is automatic switching between a more powerful GPU for high intensity graphic tasks with ...

open /etc/default/grub using sudo gedit /etc/default/grub and add nouveau.blacklist=1 at line GRUB_CMDLINE_LINUX_DEFAULT=" " and remove the quiet and splash to see the kernel messages .this blacklists the nouveau driver on bootup after suspend/hibernate this worked for me on a Dell Vostro 1500 with GeForce8600

Open up the terminal and type the following. It will ask for your password and to confirm it sudo apt-get install fglrx

Thanks to @ubfan1 I managed to find out what the issue was. Reinstalling the driver from the terminal gave a ERROR (dkms apport): kernel package linux-headers-4.2.0-040200rc7-generic is not supported In conclusion the problem is the Nvidia driver does not currently support my kernel until 4.2 is actually released.

I had to drop back to Lubuntu from Ubuntu after the Ubuntu 14.04 updates left the system too glitchy. The Nouveau driver worked under Lubuntu, but ran too hot, but the Nvidia 304.125 was better (still warm, but runnable). Unity is the killer for you, try another desktop, and that might be your solution also. I did succeed in getting Ubuntu 14.04 to ...

I had the same problem today. Starting the system by live cd I found out in deed that in the file /boot/grub/grub.cfg there were listed old kernels 3.19.0-16 and 3.19.0-15. I changed this to 3.19.0-26 and 3.19.0-25 and could then luckily reboot without any further problems. Perhaps this is also the case with your system?

I don't know about the Minecraft but if you want to install Nvidia driver, take a look at this question. To make it short, you should go to additional driver, choose the driver which is proprietary and tested. Then install nvidia-prime package.

I also experienced a screen freeze problem similar to the one you described, after a recent upgrade from Ubuntu 12.04 to 14.04. The upgrade also led to occasional forced logout. My computer is running on an Intel i5 CPU and 4GB RAM. I used htop to investigate what processes were keeping my CPU busy. I saw a suspicious process compiz and wondered what that ...

As I studied the programming language C/C++ we did use a library called Allegro, which seemed to be a good & easy library to do graphics programming in. http://liballeg.org/

If the reason for bad looking fonts is disabled anti-aliasing, then there are few things you could try: In LibreOffice: Go to Tools in the top menu -> then Options. In the left treeview go to LibreOffice -> View (4th from top). Here are some settings for LibreOffice (like "use Anti-Aliasing"). If your whole system lacks of Anti-Aliasing (what I don't think ...

At last, I have found the answer. NVIDIA GeForce 940M is a new gpu. so all what you have to do is install cuda 7.5. When I install cuda with ubuntu 14.04. It worked without any problem. Bust sometimes it caused some issues. And then I installed ubuntu 15.04 with cuda 7.5 and it's working fine without any trouble.

You can install the latest drivers by adding the brand-new NVIDIA PPA: sudo add-apt-repository ppa:graphics-drivers/ppa And installing or upgrading the drivers: sudo apt-get update && sudo apt-get install nvidia-355

For any one who might come across this in the future i have solved it. What I did in the first place was use fglrx-updates, without ever using the original fglrx driver. Once i switched over i am able to play my games and there is no screen tearing.

Normally the official AMD driver (fglrx) handle correctly hybrid systems. Another way to go, is to force the use of the discrete card by using a custom /etc/X11/xorg.conf. Some ressources to help you : the documentation on how to write this config file you can try to understand the configuration provided in this post Be careful, in the Device section ...

The most up to date instructions for installing the binary driver can be found on this unofficial wiki page. If you don't intend to play games, I would advice you to stay with the open source driver (radeon) which will give you the most performance in 2D. For more help, please attach the result of /var/log/messages and the content of /var/log/Xorg.0.log ...

They advice you to add ppa:ubuntu-x-swat/x-updates repository, so the command will be : sudo add-apt-repository ppa:ubuntu-x-swat/x-updates And then update the repository index : sudo apt-get update See also : What are PPAs and how do i use them ?

What they ask you to do is ... sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update This will update all the software that that repository holds (and that includes dota2).

Tested at the end of the driver name in the Additional Drivers utility means the driver is considered to be first class in terms of stability and reliability. Other drivers that are not tested could be considered to be second class by comparison. The reason why there are different grades of graphics card drivers is that for newer models of graphics cards ...

Turns out OpenGL 4.0 isn't supported by Linux at the time of this post. If you are having this problem you will have to wait until Mesa 11.0 is released, in which OpenGL 4.1 will be supported.

Please try running the following command in terminal: sudo lshw -C display It should return information about your graphics details.

The reason it is saying temporarily unavailable is because you are stopping the process by clicking the [x], when it is running and you let it run for a couple of seconds you see the frame rate in the terminal, right? When you stop the process then it cannot tell you the frame rate, therefor the resource becomes unavailable, nothing to worry about.

First of all to get much trusty results, glxspheres is better than glxgears. You can use "vblank_mode=0" for get higher results but it is all about v-sync. If you can run a program with optirun command there is no problem to worry about because your Nvidia card works. You know that your Nvidia card is working but don't know working fine or not, for that ...

I had the same problem. Just delete Bumblebee sudo apt-get purge bumblebee* And then just say "hello!" to Nvidia-Prime sudo apt-get install nvidia-prime After selecting your graphic card from nvidia-settings, (intel or nvidia) you should log out and come back. (Unfortunately after every changes)
