Screen corruption and keyboard issues with iMac 13,2 Fedora 43, GTX660M

Getting this weird situation with windows and the keyboard racing (until i hit ESC) in apps. I am using the Neuvauo driver i believe as the previous nvidia-470 only supports X11 or it black screens. New install rather than upgrade. Added the broadcom-wl driver manually to get wifi working.

So this is a new install rather than an upgrade. FWIW, one of my systems is a MacBook with an even older NVidia GPU, and I’m using it with the Nouveau drivers just fine.

Can you post the output of:

lspci -k | grep -EA3 'VGA|3D|Display'

Either post here the above output, or, if the driver in use is nova_core, which might need blacklisting, you could go ahead with the additional steps below.

First try temporarily adding the following arguments to your boot menu at system startup, by selecting the first boot entry, editing GRUB with e, and adding the following to the end of the line starting with linux:

rd.driver.blacklist=nova_core modprobe.blacklist=nova_core

If with the edited boot command the system is behaving as expected, then you can make the changes permanently following the steps described here:

FWIW, in the past I needed using gl, (since F40) then vulkan (in F42) for GSK_RENDERER, but after upgrading to F43, the systems behaves well with no value manually set up.

Is nova_core not taking precedence over nouveau in current kernels anymore?

Nova-core module is no longer included in recent kernels.
