In a lot of distros, vdpau which accelerates video through the GPUis often not installed even in recent distros. This will result in Firefox with Youtube dropping frames when you check the "Stats for Nerds" and to the eye as jerky or slower video playback due to the dropped frames.
Some sites will say that because you are watching VP09 that there is no GPU support, but with vdpau installed and enabled, many GPUs will still be able to use hardware decoding for 4K........
If you get this error, it is often because you have configured Apache with modules that weren't actually installed. Eg. you try to load the PHPmodule but didn't actually install the apache2 php module, so the server can't start. In general, this error can often be caused by issues with problematic modules and/or Apache being configured for modules that have not actually be installed (eg. libapache2-mod-php) is missing.
The above results in this less than obv........
The issue is that Docker images are stripped down, so many tools and even python3 is missing, so you'll have to build or update the actual image yourself.
I assume you have started an image with something like this and that you have the Nvidia Toolkit installed (assuming you are using GPUs). If you're not using nvidia just remove --runtime=nvidia --gpus all.
docker run -it --runtime=nvidia --gpus all ubuntu bash

The passwords are stored in the following locations on Unix/Linux:
The directory is usually inside your home like this:

Without the key file you will not see any passwords in Firefox as it is required to in order to decrypt the contents of logins.json........
This is a weird issue in Mint Ubuntu gnome that I've only seen on one system. It may happen in your terminal or your browser but one program will just refuse to allow input from the keyboard. I am not sure if it's some weird fluke on a strange keyboard by perhaps accidentally hitting a weird key combination.
In some windows the keyboard gets weird and only / and Esc seem to work.

This can be used on almost anything, since Gluster is a userspace tool, based on FUSE. This means that all Gluster appears as to any application is just a directory.
Applications don't need specific support for Gluster, so long as you can tell the application to use a certain directory for storage.
One application can be for redundant and scaled storage, including for within Docker and Kubernetes, LXC, Proxmox, OpenStack, etc or just your image/web/video files or even da........
If your audio is not working and you got this in your syslog:

You might assume you have a bad drive or the SATA interface/cable is bad, or the power supply is bad/weak to the drive. These are all possible issues, but definitely check your SATA cable for "twisting". It is a big issue because until the error stops or times out, your system will not boot (in my case this was the case even though the drive with the issue was not part of the OS or booting process at all).

This happens to a lot of Nvidia users especially users of newer cards like the RTX series.

One thing to note about DNS servers and providers is that they aren't always trustworthy, not even if they're Google or your favorite ISP.
