Hello everyone.
A few questions.
I want to switch from Fedora.
Is there a problem unlocking the screen (GNOME) with NVIDIA drivers after going into sleep mode? (There is one in Fedora.)
Codecs to avoid breaking the system (Firefox Flatpack?)
Thanks.

Questions too generic for a detailed answer, maybe sharing the output from inxi -GSz(even from another distro) helps.
Anyway there are still occasional problems with power management of some Nvidia chips, especially when resuming from suspend, but I think those are kernel/driver issues rather than Gnome or distro-specific issues.
For codecs there are a few options, depending on your HW and your user needs, but generally speaking the standard Firefox is enough for most users.

Fedora problem

Your system has dual graphics, possibly an “Optimus” laptop? If so, the Nvidia chip should only be used for graphics offload and even if powered down should not automatically suspend the system. Nevertheless it might be impossible to suspend if an app is engaging the CUDA compute engine (e.g. LibreOffice Calc with openCL enabled or some graphics apps like Darktable); that depends on the Nvidia model, I don’t know if the RTX 3060M is affected, other users may have better relevant info.

On Tumbleweed systemd is at 258.4, don’t know how that compares to Fedora.

Just need to install and check. ) Merci.
