Elgoog I have read that secureblue isn't quite ready for prime time. Are you finding any rough edges?
Oh ? I wasn't aware of that statement. I use SecureBlue without any problems for work and gaming. Installation is very easy, it's very stable, and it runs like clockwork. In short, there can always be problems, but I haven't encountered any yet.
Note that there is one thing I did after installation, I enabled Xwayland with the command ujust toggle-xwayland, this reduces security, but otherwise some softwares I use doesn't work.
The only thing that caused me problems were VMs, but that's not specific to SecureBlue. I don't understand how to run VMs in immutable Linux distributions. I have Fedora KDE on a second SSD for VMs.
