Been lurking here for a while, but decided to install the latest ISO (April '24) WITHOUT the proprietory Nvidia driver. Like many of you, I have watched the development of the open-source drivers for a while, and it encouraged me to try KaOS without the chance of breakage due to the driver.
Works beautifully.
Sleep, updates, all work as expected.
I will add that I must work in Microsoft's space a good deal. For that I use MS Edge as a Flatpak, and have everything from Office 365 to voice-to-text working very well. Pipewire has helped make my audio routing for external microphones, headphones, and speakers easy for conferencing. Wayland now works very well on this old Intel i5 6600/Nvidia 950 system.
Bravo to the developers and testers.
