COS Config Center¶
COS Config Center handles, in a graphical interface, nine things that on Linux normally take the command line. It is exclusive to CapivaraOS and ships preinstalled on all three desktop editions.
To open it, look for COS Config Center in the application menu.
It asks for the administrator password only for settings that touch the system, and always warns first.
Software and drivers¶
Codecs and extra repositories¶
Enables the RPM Fusion repositories and Flathub, and installs the codecs Fedora cannot ship by default for patent reasons. This is what makes video and music "just play".
These are third-party repositories
RPM Fusion and Flathub are run by their own communities, not by CapivaraOS or Fedora. Some formats are covered by patents in certain countries — worth checking what applies where you live.
Disks and maintenance¶
Free disk space¶
Shows what can safely be removed, split into two lists: what lives in your user account (trash, thumbnails, unused Flatpak runtimes, container images) and what lives in the system and needs the password (already-installed packages, old logs, crash dumps).
Each item shows how much it takes before you decide. Nothing is removed unless you tick it.
Disks at startup¶
Mounts your extra disks and partitions automatically when the computer starts, without you editing /etc/fstab by hand.
System log size¶
Caps how much space system logs may use, so they do not grow forever and fill the disk.
System check¶
A quick health check: disk space, running services, the video driver in use and errors since the machine booted.
At the end it builds a report to paste on the forum when you ask for help. The report does not include your name, the computer's name or network addresses.
Keyboard and language¶
Brazilian keyboard¶
Choose between ABNT2, US International and US — and, on US International, enable typing ç with ' followed by c, the detail that most annoys anyone writing Portuguese on a US keyboard.
The same layout can be applied to the login screen as well.
Language and formats¶
Separates two things that usually come glued together: the language of menus and applications, and the formats for date, number and currency. You can run the system in English while keeping Brazilian date and currency.
It applies system-wide, login screen included, and takes effect after you log out and back in.
Network and security¶
Firewall¶
Shows what is open to the network in plain words — "share folders on the network", "remote terminal access", "web server" — instead of port numbers.
There is also strict mode, which closes ports above 1024 and lets through only what you turned on.
Remote access and network¶
Changes the computer name on the network, turns SSH remote access on or off, creates your SSH key and configures encrypted DNS.
Two caveats in this release
SSH password login stays enabled — we do not alter sshd_config. And encrypted DNS can break names that only exist on your local network; if something stops resolving after you enable it, switch back to "Automatic".
About this release¶
COS Config Center ships with Series 2 as 0.11.x, a first public release with these nine modules. 1.0.0 will come after feedback from the people using it.
Not in this release: the NVIDIA driver (that is COS Dev Center's job), dual boot configuration and video acceleration.
System updates do not go through here either — those belong to the software centre or dnf. See Updating the system.
