GRUB_CMDLINE_LINUX_DEFAULT="quiet splash XXX.modeset=1" GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" This is a sample command line that opens the file with gedit text editor with root/admin privileges sudo gedit /etc/default/grub Open that file with a text editor with root/admin privileges. These settings are stored in grub's (the bootloader) own setting files in /etc/default/grub The vga_switcheroo mechanism will only be active when the kernel is booted with either the "modeset=1" kernel option, and/or the "nomodeset" option being absent. If there is CONFIG_VGA_SWITCHEROO=y then what we need is there and we can proceed. This is an example of the result, with kernel version 4.1 /boot/config-4.1.0-1-amd64:CONFIG_VGA_SWITCHEROO=y To check whether your kernel is compiled with the proper option you can examine the file config-2.6.nn-mm-generic in the /boot directory: sudo grep -i switcheroo /boot/config-*
Note that this method is not supported by all machines and only works if you are using the opensource driver (nouveau, radeon) and not the proprietary ones (nvidia, fglrx). Vga_switcheroo is the kernel mechanism that allows you to switch between GPUs if your machine has a hardware mux. The kernel shipped in Ubuntu 10.10 supports hybrid graphics by means of the vga_switcheroo flag. The integrated GPU is often embedded in the CPU, hence the name. Restart the system to apply the changes.Some laptops come with two graphics cards: one for use in applications that require a lot of computing power such as games, called the discrete GPU, and one that is less powerful, but conserves energy, called the integrated GPU. Allow some time to download and complete the process and click on the close button when done.Ħ.
Click on the Apply changes button to install the driver.Ħ.
Select the first ‘Nvidia – drivers 430’ (proprietary) to install Nvidia driver 430.ĥ. You will see 2 options ‘Nvidia – drivers 430’ (proprietary) and ‘Nvidia – drivers 390’ (proprietary) available for GeForce GTX 1080 Ti card. In this case, click on Additional Drivers, you can see there, the ‘Nvidia – driver -435’ (proprietary, tested) is set up as default driver used for Nvidia card, along with some proprietary divers listed.Ĥ. At the top-most section of the ‘Software and updates’ windows, be sure to find a couple of options displayed which include Ubuntu software, other software, updates e.t.c. This will launch the ‘Software and Updates’ window.ģ.
On the software updater pop-up, click on the ‘Settings & Livepatch’ button.
Open Ubuntu Dash and type “software update manager” and click on it to open.Ģ. NOTE: You can also install Nvidia drivers using from GUI. Once installed, verify using the command “nvidia-smi”. Once installed, please update the system: Sudo add-apt-repository ppa:graphics-drivers/ppa Install Nvidia driver from the command line (CLI) If an error message displays, you need to install the development tools from your Linux distribution or obtain a version of gcc and its accompanying toolchain from the Web. To verify the version of gcc installed on your system, type the following on the command line: It is generally installed as part of the Linux installation, and in most cases the version of gcc installed with a supported version of Linux will work correctly. It is not required for running CUDA applications. The gcc compiler is required for development using the CUDA Toolkit. The remainder gives information about your distribution. The x86_64 line indicates you are running on a 64-bit system. Red Hat Enterprise Linux Workstation release 6.0 (Santiago) You should see output similar to the following, modified for your particular system:
To determine which distribution and release number you’re running, type the following at the command line: These are listed in the CUDA Toolkit release notes. The CUDA Development Tools are only supported on some specific distributions of Linux. Verify You Have a Supported Version of Linux If your graphics card is from NVIDIA and it is listed in, your GPU is CUDA-capable.
If you do not see any settings, update the PCI hardware database that Linux maintains by entering update-pciids (generally found in /sbin) at the command line and rerun the previous lspci command. To verify that your GPU is CUDA-capable, go to your distribution’s equivalent of System Properties, or, from the command line, enter: * Handle conflicting installation methods.
* Verify the system has correct Linux kernel headers and development packages installed. * Verify the system has build tools such as make, gcc installed * Verify the system is running a supported version of Linux * Verify the system has a CUDA-capable GPU
