[SOLVED] After updating the system bbswitch don't work with linux-lts kernel

Today I updated the system. After turning on my laptop I noticed (I have the bumblebee monitor in my plasma desktop) that the nvidia card is on. I restarted the service in case something went wrong during boot, the service  restarded well but shows me a fatal error about not finding the bbswitch module.

In my laptop I have the two kernels, the regular one and the lts one (its the default one). With the regular kernel  (5.8.2-artix1-1) works well without problems so I decided to reinstall bbswitch-dkms. It failed again and gave an error with the lts kernel and informs where the log file is. With the other kernel, no problem at all.

This is whats inside the log file in "/var/lib/dkms/bbswitch/0.8/build/"

It looks like there is some kind of incompatibility with the gcc version. What is strange is that with the regular kernel it works well.

Is this a real problem or is it just a matter of time to get a new version of gcc (

Thank you for your answers in advance

Works fine here.
Try to update your system, there is already linux-lts.5.4.60
There might have been some updates for gcc or something.

My system says its updated and I have the latest version (linux-lts-5.4.58-1).
I see that there is a lts-5.4.60 version in Arch but is in testing.

I wait to test again when a new lts kernel appears here in Artix. Meanwhile I will use the regular kernel instead.

Thank you for your answer.

yeah, I am using testing.
I forgot about this fact.

You are right, it does not work with 5.4.58 kernel.

I don't know if it's of any use but this afternoon trying to solve the problem I found in reddit that void has a similar problem during a kernel update, it isn't the same kernel but maybe it is usefull. I found the info here.

Upgrade your kernel to 5.4.60. That should fix your problem. New kernel is builded with the newest gcc which was delivered to our repo yesterday.

I updated the system now and yes, with the new version all works well again.

Tank you.
