Doesn't work on Debian 11

[tazihad]

I see black screen when reboot. Completely turned off screen. fortunately I recovered from recovery screen. please mention Debian 11 not supported in wiki. So, other people won't have to face same issue.

I am currently running Debian 11 on a Haswell CPU / Maxwell GPU Optimus laptop using the Nvidia binary drivers plus prime render offload and am thinking of trying envycontrol. However your comment has me hesitating a bit!

Some more info would be needed to aid debugging however:

1. Can you describe how you installed this on Debian 11?
2. Which mode did you enable prior to rebooting (integrated / hybrid / nvidia)?
3. Were you using an external monitor or internal laptop display?
4. What model of laptop are you using (trying to determine how the display outputs are wired)?

@porschemad911 Debian 11 base it's relatively new, I remember testing envycontrol on Ubuntu 20.04 with 470 drivers.

Hybrid mode / render offloading should work since 435.17.

@zihadio what's your iGPU/dGPU combination as well as Nvidia driver version and lspci output?

Edit: currently using Fedora 36 KDE on my laptop on Nvidia mode in order to utilize my 144hz monitor.

Thanks

This evening I tried envycontrol out on my Metabox P650SE with Intel 4th gen CPU and GTX 970M, running Debian Bullseye (11) and Nvidia 515.65 drivers installed from the Nvidia repo at https://developer.download.nvidia.com/compute/cuda/repos/debian11/x86_64/

I'm using an xdm / lxqt setup and the integrated and hybrid modes worked flawlessly for me. I got an error attempting to switch into the nvidia mode because xdm is not a supported display manager.

This laptop conveniently has an indicator light to show whether the Nvidia GPU is powered on. In integrated mode the indicator light is off, nvidia-smi, nvidia-settings and nvtop report no Nvidia GPU detected, lspci does not pick up the Nvidia GPU and power consumption indicates 13 - 14W under light loads.

In hybrid mode the indicator light is on, nvidia-smi, nvidia-settings, nvtop and lspci show the Nvidia GPU with a reported 5W power consumption when not in use, power consumption indicates around 22W under light loads on the Intel GPU and I am able to use prime render offload to launch games etc on the Nvidia GPU.

@geminis3 Kudos to you, this util is working really nicely for me! t would be a bonus if xdm support could be added, although nvidia mode is not a high priority for me and I doubt many people are using xdm these days anyway.

1. installed using this method.
2. I tried all of them from tty.
3. I have external monitor. But I also tried without ext monitor.
4. it is Asus x550jk. laptop display is directly connected to integrated gpu.

@tazihad are you still experiencing this?
