I just did a Brave A.I. Search via mojeek search engine and got this:
"KDEnlive Freezing on Ubuntu 22.04
KDEnlive freezing in Ubuntu 22.04 with an AMD processor and graphics card can be due to driver issues or conflicts between the AMD and NVIDIA drivers if both are installed. One approach to troubleshoot this issue is to ensure that only the necessary drivers are active and that any conflicting drivers are blacklisted. For example, if an AMD GPU is integrated into the processor, but a separate NVIDIA GPU is also present, the AMD driver should be disabled to avoid conflicts with the NVIDIA driver.
To resolve the freezing issue, you can try the following steps:
Ensure the latest drivers for the AMD GPU are installed.
If a NVIDIA GPU is also present, blacklist the AMD GPU driver in `/etc/modprobe.d` to avoid conflicts.
Update the system and install any necessary compatibility libraries:
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get update
sudo apt-get -f install
sudo apt update && sudo apt upgrade -y
sudo dpkg --configure -a
Install the NVIDIA drivers from the PPA if a NVIDIA GPU is present:
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt install nvidia-driver-555
Restart the system after making these changes.
Additionally, you can check the system logs in /var/log and crash files in /var/crash for any error messages that might provide more clues about the freezing issue.
If the problem persists, it might be helpful to switch from Wayland to Xorg as the display server, as Wayland support for NVIDIA hardware is still relatively young and might cause issues.
If none of these solutions work, consider testing KDEnlive on a live session of Ubuntu to determine if the issue is specific to the installed system or if it is a more general problem with the software or drivers."
I only recently discovered myself that AMD has it's own microcode package (just to add I am running PCLOS Debian) in Synaptic Package Manager.
