Unfortunately no way to switch off the Intel Graphics from the BIOS. > Check at the website of the builder of your laptop, and > maybe ask them if it is possible. That's the simplest solution.

They are focussed for Windows. > I was going to suggest building a kernel without the intel driver Ok before I about compiling my own kernel I would like to inform you about what I have done so far. So I have followed the instructions of : https://help.ubuntu.com/community/HybridGraphics The first thing it asks you to do is add a kernel parameter to GRUB_CMDLINE_LINUX, so I added the following parameter : radeon.modeset=1 Now I rebooted and checked the status as per the instructions in the page. I used the command: sudo cat /sys/kernel/debug/vgaswitcheroo/switch Output: 0:DIS: :DynOff:0000:01:00.0 1:IGD:+:Pwr:0000:00:02.0 So far so good. This makes sense since I suspected the Integrated Graphics was being used and the Discrete Graphics card ie. AMD was off. The tutorial then instructs to turn on the discrete graphics and connect it to the graphics output using these two commands: sudo echo ON > /sys/kernel/debug/vgaswitcheroo/switch sudo echo DIS > /sys/kernel/debug/vgaswitcheroo/switch Now is were things get weird. Running these two commands with "sudo" results in a permission denied error. bash: /sys/kernel/debug/vgaswitcheroo/switch: Permission denied Which is weird, I mean what the hell is the point of using "sudo". Running these commands as root - DOES ABSOLUTELY NOTHING. No error. No lockup. Nothing. I even checked the status using the command mentioned above and it still gave me the same output where the discrete graphics is turned off and the integrated one is used. I have to tell you, I was doing all this in Wayland and not X. Weirldy after modifying the GRUB_CMDLINE_LINUX I am getting "radeon" in my boot log. You can find my entire log here: https://pastebin.com/3wqhaDAY (I hope I am not exposing any sensitive information) So any suggestions ? Anything at all ?
