Debian Check Active 3d Controller Driver

Feb 02, 2018  Getting your soundcard to work, using Debian on non-i386 hardware, etc. I'm using Debian 8, but my integrated graphics card does not seem to be used. This is on an Asus Zenbook UX303 which uses HD 5500 integrated graphics.

  • Debian 9 Install Nvidia drivers on Asus Zenbook UX501 I am starting a new thread after this one, because I misidentified the issue I was facing at first, as being related to the installation process, and, as it turns out it is more of a nvidia driver issue.
  • Method 1: Additional Drivers The most trivial way of installing your Nvidia drivers. Open the Ubuntu Software Center, go to Edit > Software Sources, click on the Additional Drivers tab, select the desired version and click Apply Changes. I would recommend using the latest updates. Demonstrated on Xubuntu 13.04 Raring Ringtail.

  • Enable Unity 3D in Ubuntu VirtualBox #23. Jeff1evesque opened this Issue May 26, 2014 6 comments. The issue is that if 3D acceleration is not made active, the CPU ends up being overburdened. Add the iso file to the Controller: IDE (Add CD/DVD Device): Finally.

I have 2 GPU's in my netbook. How do I know which one I'm actually using at any given moment?

I've just gone through a hell of a time trying to get my discrete graphics to work in Ubuntu and answering this questions was constantly a challenge, since the lspci method mentioned earlier can sometimes say that both are [VGA controller]

I think the following command should give you an indication of your active chip:

For me this is telling me that my intel graphics are running the show. If you're using an nvidia chip, and you're using the bumblebee package, you can put optirun in front of that line and it should tell you that you're running the NVidia chip (optirun is basically telling the computer to use the discrete chip to run whatever command follows, but everything else is still using the integrated chip)

glxheads also tells you some useful information about which graphics card is in use (mostly repeats glxinfo in a more compact and easy to read form tho), and it gives you a nice rendering of a rotating triangle.

To check which GPU is currently in command (that means which is an active VGA controller) type in

Any controller with [VGA controller] at the end is your currently active GPU. The others are switched off. In the following example the Intel card is active while the nVidia one is not in use:

nvidia-settings GUI

On Ubuntu 15.10, after I installed nvidia-352 and the GPU seems to work:

shows something like:

Note how it shows:

where NVS 5400M is my GPU model.

Then if I fire glxgears, the GPU usage goes to > 90%.

So I expect that if you had multiple GPUs, you could see how much each one was being used at a time.

This gave me what I wanted. This command shows the list of GPUs present on your machine. This might help you figure which are active ones.

got the command from thread here: Ubuntu Box with multiple NVIDIA GPU Cards | devtalk.nvidia.com

Which OS are you using? If you use lspci on most linux machines you get a list of your pci devices, just grep for graphics devices and it should pop up both of them. After that just check out the config on each of them, you should see details of up/on/active or something to that nature.

nvidia-smi is very useful, but at times I've found that it doesn't always include everything. It seems when processes crash they aren't always listed.

sudo lsof /dev/nvidia* has always worked for me. It will also work without sudo, but will only show processes owned by you. If you are working on a multiuser machine or are using docker, you will probably get better results with sudo.

If you see a discrepancy between the 2 commands, you may want to consider killing the extra processes found with lsof.

I'm using Debian 8, but my integrated graphics card does not seem to be used.

This is on an Asus Zenbook UX303 which uses HD 5500 integrated graphics:

It seems to say there is a driver in use, however, it doesn't seem the machine is actually using that graphics card:

How do I get debian to actually use the integrated graphics card?

I've also tried the 4.0.2 kernel from unstable, which doesn't change anything; uname:

Unfortunately Jessie as released doesn't fully support Broadwell graphics. The required drivers have been backported though, so if you enable Jessie backports you can fix this.

First you need to add Jessie backports to your repositories, if it's not already there (thanks to Anders for the reminder to use a separate file):

(as root), then

should allow X to use your HD 5500 properly.

Enabling backports is safe: newer packages are not picked up automatically from backports, you need to explicitly select them using -t jessie-backports as above.
