Please run inxi -Gazy. You didn’t even provided the GPU vendor, model, etc.


I used to recommend the use of this options for hybrid graphics. All the links point to the archived forum. The list is in descending order based on the rate of success i noticed over time:

Each has advantages and disadvantages, and on some laptop models/GPU models might fail to provide the desired result, so, there is no 100% guarantee for any of them. An example is Dell XPS 9560
