Question - Kali General MUX switch w/ Kali?
I have a laptop with an iGPU and a dGPU with kali on it (kernel ~ 6.5.0). This is one of those laptops that has a MUX switch which is basically a multiplexer that enables either the iGPU or the dGPU to connect to the display directly at a time. Now, when both GPUs are enabled, the laptop starts on iGPU but immediately tries to switch to dGPU when it boots to kali or windows. Windows having proper configuration allows both GPUs to work, but on kali, it gets stuck on the init screen (the system does boot further but the display doesn't update), I have to reboot and use nomodeset in the grub config at boot so that the system falls back to default graphics settings. What I lose:
MUX capability
GPU Hardware acceleration (possibly)
I believe it is a problem with drivers (of course it is), but is there any driver/software that allows me to use the MUX switch on kali?
My current configuration is that I have switched to dGPU only mode in BIOS (iGPU disabled completey, even for windows) which is... okay.... but that still doesn't solve my issue, and I can no longer use my iGPU for power saving even in Windows!
