For Nvidia GPUs there is a tool nvidia-smi that can show memory usage, GPU utilization and temperature of GPU. For Intel GPU's you can use the intel-gpu-tools. AMD has two options, fglrx (closed source drivers) aticonfig --odgc --odgt And for mesa (open source drivers), you can use RadeonTop . Source:GPU usage monitoring

Graphics cards help with: CUDA/OpenCL style workloads (eg bitcoin mining) 3D rendering. You might be rendering stuff on demand. Most cards can help with video decoding but this applies to many IGPs too. Some cards have hardware to help with video encoding. The quality is usually a lot poorer and this is still under development. ffmpeg can use nvenc ...

Excellent question. Workloads The /usr/share/xdiagnose/workloads directory has a set of workloads designed to exercise your graphics system to trigger lockups. $ ls /usr/share/xdiagnose/workloads/ README do_monitor_rotation_loop do_chws_loop* do_screensaver_loop* do_cpu_spin_loop do_video_loop* ...

You did all wrong (almost). Run sudo apt-get purge nvidia* sudo apt-get purge bumblebee* primus sudo add-apt-repository ppa:graphics-drivers/ppa sudo apt-get update sudo apt-get install nvidia-352 nvidia-prime sudo add-apt-repository -r ppa:bumblebee/stable and hope that you did not spoil everything completely with previous attempts.

I'm wondering what is causing that difference. It mostly depends on what software you run on Windows and on Ubuntu. In general Ubuntu has less software active and Windows tends to pre-load a lot of software during booting to speed things up when the desktop is active. Both might add to lower/higher temps. Can you help me find an answer? Sure but ...

Its because your GPU (or the driver being )is not supported for WebGL. Its browser blacklisted. However you can force enable your GPU for WebGL. Warning: Do this at your own risk. It can harm your hardware. There are usually good reasons (like some critical driver bug) why features are blocked. To launch chrome ignoring the black list, run following ...

TL;DR: Unless you have tried everything below and now you get a black screen hitting this particular fixed bug, your problem should be solved by now. If you now get: ERROR:gpu_video_decode_accelerator.cc(208)] Not implemented reached in void content::GpuVideoDecodeAccelerator::Initialize(media::VideoCodecProfile, IPC::Message\*) HW video decode acceleration ...

Nvidia: to continuously update the output of nvidia-smi, you can use nvidia-smi --loop=1 (refresh interval of 1 second) or nvidia-smi --loop-ms=1000 (refresh interval of 1000 milliseconds). -l SEC, --loop=SEC Continuously report query data at the specified interval, rather than the default of just once. The application will sleep ...

Run lshw -c video | grep 'configuration' to see the video driver used, or lshw -c video for more detail. i915, for example, means your video adapter uses the Intel 915 drivers.

First uninstall all already installed NVIDIA drivers software ... boot the PC. Highlight the Ubuntu entry in the GRUB boot menu and press the E key. Add nouveau.modeset=0 to the end of the linux line - press F10 to boot. On login screen press Ctrl+Alt+F1 - enter user name and password - execute : sudo apt-get purge nvidia* sudo reboot Now reinstall ...

You can get the reading using aticonfig --odgt.

It's because your GPU (or the driver being used)is not supported for WebGL. It's browser blacklisted. However, you can force enable your GPU for WebGL. In Google's Chrome: chrome://flags/ Enable. Override software rendering list. This can have unstable results. As "Accelerated 2d canvas is unstable in Linux at the moment and Stage3D is not supported on ...

Ubuntu comes with vgaswitcheroo since 10.10. Therefore you can although it is far away from working as smooth as on Windows. Yet it's enough to turn off either one of the cards and/or switch to using the other ones. You find more information on this topic on help.ubuntu and this linux.blogspot. Since you are fairly new to Ubuntu, I'll tell you the ...

It's an interesting idea and I can't see why it wouldn't work on a technical level because Linux does support ExpressCard devices (as PCIE) so the riser on the other end should work and it should detect the graphics card too. From there it's just a case of using the nvidia drivers. However there are some things that might give you grief: You might need to ...

I can confirm that it works in 12.04. Tested with PE4H + EC2C on a thinkpad x220, using an Nvidia GTX 560ti. The tricky part was getting a working xorg.conf. I needed the nvidia drivers : sudo apt-get install nvidia-current You need to find the correct pci bus for the graphic card. lspci gave me : 05:00.0 VGA compatible controller: NVIDIA Corporation ...

No, all current Nvidia Geforce cards only support two monitors. Even in Windows. For three monitors you either need two cards or a different brand that will support all three at once (ATI/AMD have some that do lots of screens but I'm not sure how well supported this is in Linux). Edit: If you're determined to stick with one Nvidia card, you can get a ...

Run one of the next commands in terminal or, better, in TTY# using Ctrl+Alt+F#, where # is a number from 1 to 6: sudo /etc/init.d/lightdm restart or sudo service lightdm restart This will restart the graphics environment. I don't know yet from what reason, but these commands worked for me only in TTY. Anyway, if you are stuck in a black screen after ...

You should install the latest stable NVIDIA drivers + Optimus support. Open a terminal and execute : sudo apt-get update sudo apt-get install nvidia-352 nvidia-prime sudo reboot In case you still have issues uninstall the current stable NVIDIA drivers. Open a terminal and execute : sudo apt-get purge nvidia* sudo reboot After the restart ...

Do not install bumblebee, install nvidia-prime instead. Before installing the new drivers remove the old ones. Boot the computer ... when the GRUB menu appears : Highlight the Ubuntu menu entry and press E key. Add nouveau.modeset=0 to the end of the linux line. Press the F10 key to boot into the Ubuntu system. When the login screen appears ...

Yes if the server generates or, for instance, re-sizes images. Software that uses, or could use, the existing graphic card for such tasks, is not unheard of. Surely, this depends a lot on what kind of software, what kind of GPU, is the suitable driver available and things the like.

That is normal for radeons -- they run hot. It speeds its own fan up when it runs hard to stay about that temperature.

No, a GPU is not necessary for Ubuntu to run on the system. However, if you don't have a serial console or some other management interface with which to visually see what you are doing on the system, you may find it difficult to work through the installation process.

Managed to resolve my issue by using Compton. All credits go to the owner of this post: http://ubuntuforums.org/showthread.php?t=2144468 Follow the instructions there but make sure you disable the current composite manager first. You can do this by: Click on the Xubuntu icon > Click on "All Settings" (bottom right corner) In the settings menu click on ...

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 | ...

I use xfce4-sensors-plugin: It needs lm-sensors installed and configured, and it is in the standard (universe) repository. The ATI sensor (when used with the radeon open source driver) should be called something like radeon-pci-0100 --- Notice however that with recent kernels the card is kept off when not used, so the sensor is not read in that ...

Unfortunately the correct answer doesn't solve your problem. Currently X.org is not able to split graphics to two different video cards. A long time ago there used to be a way to do this using Xinerama, however only the proprietary drivers still support Xinerama. IOW, you can't do this if one of the GPUs is Intel Graphics. Now, you can get this to work ...

First uninstall all existing NVIDIA related drivers and software : sudo apt-get purge nvidia-* sudo apt-get purge bumblebee Carefully check what will be removed before you confirm. Then install NVIDIA 331 driver and Optimus functionality : sudo apt-get install nvidia-331 sudo apt-get install nvidia-prime Reboot your computer. Note ...

Don't know how and why, but after some tries I was able to install the proprietary AMD drivers and the AMD Catalyst Control Center successfully. However, only the drivers from fglrx-updates worked. After several attempts (and reboots) I was able to configure the amd graphics (using the command amdconfig --adapter=all --initial) and now I can switch between ...

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.
