It is possible to include packages in an Ubuntu distribution by using UCK. Ubuntu Customization Kit is a tool that helps you customizing official Ubuntu Live CDs (including Kubuntu/Xubuntu and Edubuntu) to your needs. You can add any package to the live system, for example language packs, or applications. Install it with sudo apt-get install uck ...

I had the same laptop, but I was on Windows and used ThrottleStop to prevent turbo mode from being activated. This stopped overheating during games and other CPU intensive operations. Check out this question as well as the tag [turbo-boost]

Not the answer you need but I run 64-bit Ubuntu desktop on Lenovo Thinkpad X121e. It is a terribly slow laptop and I gave up trying to run Windows 7 on it. Except for speed and lack of CD/DVD player I have no issues. I started using 12.04 LTS and have upgraded to 14.04 LTS

If you're running this on Oracle VirtualBox, uncheck the Enable 3D Acceleration box under the Display settings. Your VM has to be turned off before you can do that. If not on VirtualBox, it would be interesting if there's another way to disable 3D acceleration. Something changed between 13.10 and 14.04. I had Enable 3D Acceleration checked previously with ...

Also happens to some HP laptops, such as my Probook 4530s. The solution is to check for a BIOS update from Dell.

I too use Dell XPS 15 and have suffered from over-heating in past when I used open source nvidia-nouveau (installed from additional drivers). Problem got solved when I started using bumblebee where you can manually switch between intel graphics and nvidia graphics. Nvidia graphics gives much better performance but is also power expensive which results into ...

First make sure you have Nvidia's own binary driver installed and not the open-source version that comes with Ubuntu (run Additional Drivers)... Then install Bumblebee in the software centre so you can switch between your build in Intel graphics and Nvidia graphics, otherwise both will be running at the same time and your laptop will overheat and run out of ...

Does HDMI1 and LVDS1 both show when you use xrandr in terminal? If so you may be able to temporarily workaround it by using xrandr --output LVDS1 --auto If there's no errors the display should turn back on. Also if you want xrandr with a gui you can use arandr: sudo apt-get install arandr

I followed your method, but when i reboot after update-initramfs, I only get black screen. What should i do? The little different is that I apt-get remove nvidia-* one by one, because if i type exactly as you do, it has error message.

I suggest you remove the nvidia drivers, and then install bumblebee, since you got optimus: sudo apt-get remove --purge nvidia* sudo apt-get install bumblebee bumblebee-nvidia After that, reboot and hope it works.

I run an app from Ubuntu Software Center called Psensor to measure system temperatures. It will give you the temp readings on the GPU and CPU (including individual cores). Here's the developer's website: http://wpitchoune.net/psensor As far as improving performance, Bumblebee is what I use as well. I don't know of any other utilities other than Bumblebee. ...

The problem here is two packages are installing the same binary file '/usr/lib/*/libOpenCL.so' without declaring a breaks/replaces or conflicts relationship between them, and so apt-get does not know to remove the other. This either needs to be fixed in nvidia-cuda-toolkit or ocl-icd. ocl-icd is shipping this file in ocl-icd-libopencl1 instead of ...

Updating from 12.04 to 14.04 solved some of my graphic problems. Suddenly the Nvidia driver was working haven't tried Bumblebee yet.

Edit: It seems it's a memory problem, xinerama makes my two cards to run out of memory with three monitors. Some people managed to solve it increasing shared memory size on the BIOS, unfortunately my cards are not integrated and I don't have that option.

Have now solved this one by re-installing the five nvidia-304 packages from Synaptic, which caused the kernel modules to be re-compiled, so now OpenCL is fine. I suppose something must have gone wrong during the online upgrade. Thanks for reading!

OK, it looks like the update server used (Taiwan) is not up-to-date, leading to unmet dependencies and other problems. In order to fix that, I went to System Settings > Software & updates > Ubuntu Software and selected "Download from: Main server" (it was previously "Download from: Server for Taiwan") The proprietary drivers can now be installed.

The NVIDIA driver has had support for Optimus on Ubuntu since 13.10. Your issue is that neither installing the NVIDIA drivers, nor installing Blender triggers the installation of the cuda toolkit. Open a terminal and issue the following command; sudo apt-get install nvidia-cuda-toolkit and it will enable the use of cuda in Blender.

You installed the driver from ubuntu repositories over a driver you manually installed. Follow that tutorial to uninstall that driver. Then remove nvidia-updates with sudo apt-get purge nvidia-331-updates nvidia-settings. Reinstall Nvidia current driver with sudo apt-get install nvidia-331 nvidia-settings

You can download the driver for your video card for Ubuntu 64bit from here. Assuming that you are using Ubuntu 64bit now. If you installed Ubuntu 32 bit, there is 331 version of the same driver for Ubuntu 32bit. Save your driver somewhere where you can easily access it, like your /home directory or your /home/nvidia directory. To be able to install your ...

You can do this without any problems as long as you use a seperate partition of course. It will show as 2 different operating systems in GRUB, so you can choose. Of course you can screw up GRUB (if you are experimenting with GRUB) because both operating systems will use the same GRUB. This won't affect the operating systems themselves so it will be easy to ...

I am using the 3.13.0-24-generic 64-bit version with the 337.12 Nvidia driver. Today I changed to the 334.21 Nvidia version. All is good. This means that we know the 337/334 versions of Nvidia do work with the 3.13.0-24-generic kernel version. What I suggest is to first troubleshoot some of the problems mentioned in Installing Nvidia Drivers Specially the ...

I received the same message after updating to 14.04 as well, and I'm just as curious to know why the nvidia-331 update package must be removed for WINE to work. In my case, this is not even an option, as it would break my current setup with switchable graphics. Hopefully, more information regarding this will emerge sooner or later. For now, however, there ...

I just installed nvidia-prime via terminal: sudo apt-get install nvidia-prime A reboot and everything worked fine.

When I did that on my xps 15 (optimus gt 540) the screen was blank, So I removed the drivers (sudo apt-get remove --purge nvidia-*) and then reinstalled ubuntu-desktop, then the resolution was fine.

Something like: sudo dpkg-reconfigure xserver-xorg should reconfigure X. Once you can login, you should just be able to download the driver directly from nVidia's site and install it that way.

I don't think so. In fact, the GPU helps to have a better video RAM memory and allows RAM to be used in other processes, instead of the integrated video processors in most of the motherboards, which spend some of RAM memory for video. Note that if you have opened a heavy adobe flash app, if would affect the performance of CPU (strongly, if you have opened ...

You will have to uninstall the Nvidia drivers, assuming you've previously installed them: Determine what packages you need to uninstall with: $ dpkg --get-selections | grep -i nvidia sudo apt-get purge them. Note: sudo apt-get purge nvidia-* should also work. Now, I believe that in order to make sure your Nvidia card isn't used at all by Linux, you ...

After a bit more googling I found someone else who had a similar problem who noticed "Fatal: No composite extension" in their unity log as well, then looked in their xorg.conf to find: Section "Extensions" Option "Composite" "Disable" EndSection I found that in mine, too. And changing "Disable" to "Enable" allows unity to run. I guess ...

Do you have optimus enabled in your laptop ? This means that you have both an intel / nvidia graphics chipset, that work together in certain ways to save power. It could be that your linux OS cannot find the nvidia chip , and hence cannot render anything on screen. If this is the case, a straightforward solution might be to try Ubuntu 14.04 , which seems to ...

I think that you have this exact bug: Installing libopencv-dev breaks OpenGl for Intel based gpu You just have to remove ALL the nvidia packages: sudo apt-get purge nvidia-* And install the following new dependencies to get support for OpenCL: sudo apt-get install ocl-icd-libopencl1 sudo apt-get autoremove

It's not the best help, but I'm experiencing a lot of problems trying to install nvidia drivers for my GT740M. While Geforce.com informs to us that driver 331.20 supports GT740M, by executing "grep -FN 'NVRM:' /var/log/kern.log", I can see: 52044:Apr 11 13:24:13 NAUTILUS kernel: [ 3270.758568] NVRM: The NVIDIA GPU 0000:0a:00.0 (PCI ID: 10de:1292) 52045:Apr ...
