Default Applications

If you’re familiar with Solus OS then you must already be familiar with its default applications, Firefox, LibreOffice, and Thunderbird installed across its Budgie, GNOME, Plasma, and MATE desktop editions. They now run Firefox 72.0.2, LibreOffice, and Thunderbird 68.4.1.

Budgie, MATE, and GNOME desktop editions ship with Rhythmbox for audio playback, with extension support for a more modern user experience thanks to its inclusion of the Alternate Toolbar extension.

Budgie and GNOME ship with GNOME MPV for video playback, while MATE ships with VLC. Plasma ships with Elisa for audio playback and SMPlayer for video playback.

Multimedia Upgrades

The upgrade to the latest FFmpeg 4.4.2 in the 4.2 series has enabled Solus OS to deliver faster AV1 decoding using dav1d as the default FFmpeg AV1 decoder. Solus now runs the latest GStreamer 1.16.2 which features several bug fixes and library updates.

Hardware and Kernel Enablement

Solus 4.1 ships with Linux kernel 5.4.12 which makes it possible for the distro to support a wide range of new hardware from NVIDIA and AMD e.g. as newer NVIDIA GPUS such as RTX 2080Ti, newer Intel Comet Lake and Ice Lake CPUs, and newer AMD Radeon RX graphics cards such as 5700XT.

Zstandard, Meet Solus

The Solus 4.1 ISO is of type ztsd and slightly larger than the XZ compressed ISOs from previous releases but has a significantly shorter decompression time – the best that has ever been achieved.

Upgraded systemd

Solus 4.1 ships with the latest version of systemd, v244, which introduces several features that users have expressed interest in. One major improvement that Solus will get in the future is around EFI support. Cloudflare DNS is now used as a fallback secondary to Google. There is improved security on 64-bit systems to reduce PID collisions and new features in systemd-resolved for DNS-over-TLS.

Other Improvements

File limits have been raised to enable ESync support so gamers can spend less time-making system configurations. Snap installation has been made more reliable using Solus’ own ahead-of-timer-compiler for AppArmor profiles, aa-lsm-hook (completely written in Go).

The release notes have an extensive list of other subtle upgrades such as Solus shipping with an updated NetworkManager 1.22.4. It adds features/options and fixes such as:

  • Added ‘802-1xoptional’ property to consider the wired 802.1X authentication as optional.
  • Don’t disable PMF on Wi-Fi connections using SAE.
  • tui: support WPA3-Personal (Simultaneous Authentication of Equals) (SAE)
  • wpa_supplicant has been updated to 2.9, which enables support for WPA3-SAE and OWE (Opportunistic Wireless Encryption).
