Fix KDE Plasma Lagging on NVIDIA Hybrid Graphics

This guide provides a workaround to launch a KDE Plasma Wayland session on laptops with hybrid GPU setups, particularly those with NVIDIA DGPU's. This method forces KWin, the Plasma compositor, to recognize and use specific DRM (Direct Rendering Manager) devices, resolving the common bug of lagging animations on hybrid setups.

1. Create the Launcher Script

First, you'll create a shell script that sets a necessary environment variable before starting the Plasma session. This explicitly tells KWin which DRM devices (your GPUs) to use.

Hello.

Since you are here, you are having trouble accessing your PGAdmin container that you created with docker and one of the reasons is this writing error.

Lets read the error first, if you came here by luck and dont know what causes you to cant access your pgadmin container lets try writing docker logs <container with pgadmins id> to our terminal first.
