Optimus? Working or not?

General Help
#11

Just did. Thanks.

Ran into that situation:

pkg: dependency problems prevent configuration of nvidia-331:
nvidia-331 depends on nvidia-340; however:
Package nvidia-340 is not configured yet.

Which resulted in this error message:

Errors were encountered while processing:
nvidia-340
nvidia-331
E: Sub-process /usr/bin/dpkg returned an error code (1)

I was trying to install nvidia-340 but that seems to be an error too.

#12

Please run

sudo apt purge nvidia-*

to remove any conflicting driver files.
Then

sudo apt clean && sudo apt autoremove

sudo apt install nvidia-331

A different error was encountered. Here is where the installation started to have some problems. Would you know what this means?:

ugh...

tells us that /var/lib/dpkg/info/nvidia-340.postinst has a typo: replace $KERNELS with $CURRENT_KERNEL then dpkg-reconfigure nvidia-340 works as expected.

How can I edit as owner this file?:

#18

Open a terminal with the keyboard shortcut ctrl_alt_t

Enter in sudo -i, then enter your password. The terminal will open as Root.
Enter in nautilus and the File Manager will open with Elevated Privileges.
Navigate to /var/lib/dpkg/info and open the nvidia-340.postinst file in a text editor.

#19

Only found this line:
NEWEST_KERNEL=$(get_newest_kernel "$KERNELS") which was replaced like this:
NEWEST_KERNEL=$(get_newest_kernel "$CURRENT_KERNEL")

Now this:

cloudwater@cloudwater-Alienware-15-R3:~$ sudo dpkg-reconfigure nvidia-340
/usr/sbin/dpkg-reconfigure: nvidia-340 is broken or not fully installed

Please try

sudo apt --fix-broken install

From the terminal logs I see that you have an Alienware M15 R3. Could you provide us your detailed laptops specifications? I have the suspicion that your hardware might not support Optimus at all.

Do you know the refresh rate of your Laptop screen? Is it more than 60?

I do not know the refresh rate of the laptop screen. Is there a way for me to find it?

I think... I found the answer.

Error! Bad return status for module build on kernel: 5.11.0-27-generic (x86_64)

https://nvidia.custhelp.com/app/answers/detail/a_id/3142/~/support-timeframes-for-unix-legacy-gpu-releases

It appears Nvidia killed support for the 340 driver at Linux Kernel 5.4

However... This may mean that installing the 5.4 kernel might work.

I did some research and it seems that your laptop does not have Optimus at all. But it seems to have a MUX switch. So it means that you can manually switch to your GPU or CPU. I think that's why in your earlier post, you had some options missing in the Nvidia X application.
Also does pressing fn + f7 do anything?
