Thank you for your replies.
I was aware of the limits of the legacy drivers, so I didn´t expect them to work in Wayland, but I did expect Nouveau to work in wayland.
In any case the drivers in rpmfusion repo have not been updated to work with Kernel 5.15:xxx
I checked if any nvidia module was still in memory and that the nouveau modules had been loaded:
[root@Andrea-Laptop2 andrea]# lsmod | grep nvidia
[root@Andrea-Laptop2 andrea]# lsmod | grep nouveau
nouveau 2400256 39
drm_ttm_helper 16384 1 nouveau
ttm 81920 2 drm_ttm_helper,nouveau
i2c_algo_bit 16384 1 nouveau
mxm_wmi 16384 1 nouveau
drm_kms_helper 303104 1 nouveau
drm 630784 22 drm_kms_helper,drm_ttm_helper,ttm,nouveau
wmi 36864 6 dell_wmi,wmi_bmof,dell_smbios,dell_wmi_descriptor,mxm_wmi,nouveau
video 57344 3 dell_wmi,dell_laptop,nouveau
[root@Andrea-Laptop2 andrea]#
Then, as suggested I checked the grub entries for nvidia and nouveau commands and found none.
The only place where I found the mentioned references was in /boot/grub2/grub.cfg:

But it looks like the default_kernelopts variable had not been used for any entry, as I didn´t find any trace of it in the kernel entries at boot time.
Shall I assume that there is a bug in fedora 35 5.15.x Kernel?
