We can force Xorg to use Intel graphics by creating a configuration file with the following contents and save it to /etc/X11/nf. It indicates the PCI bus id that the Intel graphics connects to.įor example, on my computer, lspci outputs 00:02.0 VGA compatible controller: Intel Corporation Device 3e92, thus the bus id is 0:2:0. Note that the bus id output from lspci is hexadecimal but the number filled in nf should be decimal.įor example, if the output from lspci is 82:00.0 VGA com., you need to fill PCI:130:0:0 in the configuration. On Ubuntu 20.04 you may want to set the driver to modesetting instead of intel. I met some problem and solved as this link (and links within it) describes. Setting with multiple monitors would be a little bit complex. Here is my example of setting with two monitors. Some fields are missing but it works as Xorg will smartly use some default configs.Īnyway, search the Internet to get a proper set of configurations for you. man nf and ArchLinux wiki are good references. Section 'Device'Īfter the configuration, reboot the computer. If it successes, you will be able to login to the desktop. If it fails, you could be locked at the login screen. Reboot to advance mode, drop to root prompt and check /var/log/Xorg.*.log.* for hints.Īfter login successfully, open an terminal and execute glxheads. GL_VENDOR: Intel Open Source Technology Center glxheads: exercise multiple GLX connections (any key = exit) The displayed rendering devices should be the Intel graphics.
