Switching from Standard to Eco Causing a black screen - Rog Zephyrus G14

Rules

• I made myself familiar with the Readme, FAQ and Troubleshooting.
• I understand that, if insufficient information or no app logs will be provided, my issue will be closed without an answer.

What's wrong?

When switching from standard to eco, a black screen occurs flickering two times. Once the screen comes back on, the taskbar is missing and only the apps that are still open remain. If you exit out of all the open apps you end up at black screen, with 4 rectangles in the bottom left corner. You cannot do anything else but if you do Ctrl + Alt + del you are brought to a pop up with sign out options.

How to reproduce the bug?

1. Occurs almost everytime after you take it off of charge.
2. (Maybe sometimes after setting balanced to silent)
3. Go to Ghelper and set GPU mode from standard to eco

@AbiramSarvananthan hello,

It looks more like a windows or nvidia driver misbehaviour.

Can you check what Display Mode do you have under Nvidia Control panel? And change it to Optimus there.

If it doesn’t help - try to do a fresh install of the latest GPU drivers from Nvidia website directly? and check Reset to factory defaults during installation.

Thanks

Right now I have it to automatic select? I just change that to optimus?

[seerge]

@AbiramSarvananthan yes, try that

Same happens here on a 2024 G16. It only started happening after updating to 24H2 and updating the intel graphics drivers (not the nvidia ones).

I will note that i used to very rarely have bluescreens when a change occurs to the graphics but since the update i haven't had any.

@AbiramSarvananthan any updates here?

Hi, sorry. As of now I have not encountered the problem again after switching to Optimus.

Те саме відбувається на G16 2024 року. Це почало відбуватися лише після оновлення до 24H2 та оновлення графічних драйверів intel (а не nvidia).

Зазначу, що колись у мене дуже рідко з’являлися сині екрани, коли відбувалася зміна графіки, але після оновлення у мене їх не було.

I have the same thing. After the update 24H2, a black screen started appearing for a few seconds when I switch the video card from standard mode to eco.

Hi, sorry. As of now I have not encountered the problem again after switching to Optimus.

Then we have an answer. Most likely it’s some recent changes in windows or GPU drivers that don’t like when Nvidia Display mode is driving display with dGPU.

My advice would be to ensure that you either have Optimus selected or Auto, but display is driven by iGPU (which is same as Optimus)

As I remember AC also tells you to do that.

Unfortunately there is no NVidia API to control Optimus setting, so G-Helper can’t set that for you.

@Edelwis @iyad08 same advice to you, make sure you have Nvidia Display mode set to Optimus (or Auto but it uses iGPU to drive display).

This is most likely some resent changes in nvidia drives / windows, as from my observations even when you were on nvidia GPU only mode in nvidia settings - switching is working just fine. But since AC "recommends" to set Optimus prior to disable dGPU - it's better to do it like that :)
