grep -i "Using input driver" /var/log/Xorg.0.log; When both drivers are installed, "synaptics" takes priority. To switch to the "synaptics" driver, install it with the command: apt install xserver-xorg-input-synaptics; Then log out and log back in. To go back to using "libinput", simply remove the "synaptics" driver: apt remove xserver-xorg ...
You can check the Xorg startup log file, usually /var/log/Xorg.0.log and look at which modules it is loading. By default Xorg can try to autodetect but you can manually force a driver by putting a Device stanza in an Xorg conf file. Here is what the Xorg startup log will look like for an nvidia card and the nvidia proprietary driver.

To use NVIDIA's PRIME render offload support, configure the X server with an X screen using an integrated GPU with the xf86-video-modesetting X driver.
Xorg can use two categories of open source drivers: DDX or modesetting. Although Xorg normally auto-detects drivers and configuration is not needed, a config for a specific keyboard driver may look...
And for Intel gfx driver, you must use xf86-video-intel 2.0.0 or above. Note: After the driver was moved to Kernel Mode Setting, the name of the output changes (such as from LVDS to LVDS1). 2. Two methods of setting up. We can set up dual head:-- dynamically by using xrandr tool or-- statically by setting in xorg.conf.
Non-MXM cards require Optimus, Nvidia's integrated-vs-discrete GPU switching technology. Non-Optimus mode. You need an MXM card (see above) for Non-Optimus mode.

The other users have a GDM login screen and can use xorg-server normally, but have no vt's. Even though a single user can utilize multiple monitors connected to the different ports of a single graphics card (cf. RandR), the method which is based on multiple instances of the xorg-server seems to require multiple PCI graphics cards. You can choose what Xorg driver to use by creating a file in /etc/X11/xorg.conf.d called 20-intel-gpu.conf with a line that either says Driver "modesetting" or Driver "intel": File: /etc/X11/xorg.conf.d/20-intel-gpu.conf

Dec 15, 2018 · Numba supports CUDA-enabled GPU with compute capability (CC) 2.0 or above with an up-to-data Nvidia driver. However, it is wise to use GPU with compute capability 3.0 or above as this allows for double precision operations. Anything lower than a 3.0 CC will only support single precision. Oct 17, 2018 · The main missing pieces — If you have not guessed it by now — are mainly multi-level network transparency and drawing command-stream buffer formats.
