Under Linux it is common that you can set the number of colours that an AMD or NVidia graphics card or the GPU unit of the CPU should display with the driver of the graphics card. But how do you set the number of colours under a Debian 12 Linux such as LMDE6 if you are using an Intel CPU with its own GPU? According to some internet sources, the number of colours can be set with the following command line: xrandr --output --setcolor 24bit However, this seems to be a misconception that such functionality is offered by xrandr. Starting points for alternative solutions: - Query the graphics type used: lspci -k | grep -EA3 'VGA|3D|Display' - Use an icc.icm color profile file and possibly adjust the number of colors by changing this file. - Modification of the data read out by the system from the display used, which can be decoded with DMI Decode: sudo hwinfo -monitor and sudo dmidecode - Change a file such as /etc/X11/xorg.conf or /etc/X11/xorg.conf.d/ , neither of which appear to be present in LMDE6 or looks like dont have the follow section. But perhaps about like the follow in a other located file: Section "Screen" Identifier "Screen0" DefaultDepth 16bit EndSection Remark: Its looks for me, Xorg are used bei LMDE6: No Wayland service looks running on LMDE6, but the well known Xorg service are running. "Linux Mint Debian Edition (LMDE) 6 does not use Wayland as its default display server protocol. Instead, it uses Xorg, which is the traditional choice for Linux desktop environments. The discussion in the Linux Mint forums indicates that while work has begun on integrating Wayland support into Cinnamon, the default desktop environment for Linux Mint, it is not expected to replace Xorg as the default display server anytime soon. The goal is to have a functional Wayland session by around 2026, but until then, Xorg remains the primary choice for LMDE 6 users." Source: https://www.phind.com/search?cache=he0i94eo7k5352vhtuggrz20
