Video Card Information and Display Resolution in Wayland

Wayland is a display server protocol designed as a replacement for the X Window System used in Linux and Unix-like operating systems. With Wayland, applications get to directly communicate with the display server without the need for an intermediate window manager.

Retrieving Video Card Information

To retrieve information about the video card installed on your system, you can use the lspci command. This command lists all the PCI devices connected to your system, including the video card. You can filter the output to show only the video card information by running:

lspci | grep -i vga

This will return information such as the vendor and model of your video card.

Display Resolution in Wayland

In Wayland, the display resolution can be set using the weston.ini configuration file. This file is located in the /etc/xdg/weston/ directory. If you need to change the resolution, you can edit this file and modify the width and height parameters under the [output] section. For example, to set the resolution to 1920x1080, you can modify the file as follows:

[output]
name=LVDS1
mode=1920x1080
width=1920
height=1080

Alternatively, you can use the xrandr command-line tool to set the display resolution on the fly. This tool allows you to list the available output devices and modes, and then set the output resolution accordingly.

To list the available output devices and modes, run:

xrandr -q

To set the output resolution, run:

xrandr --output VGA1 --mode 1920x1080

Replace VGA1 with your output device name as listed by the xrandr -q command, and 1920x1080 with the desired resolution.

Remember that not all video cards support all display resolutions, so make sure to check the video card vendor's documentation for the supported resolutions.

Overall, both lspci and xrandr can aid you in retrieving information about your video card and setting your display resolution in Wayland.
