ErgenOS 1.2.0

ErgenOS 1.2.0

ErgenOS 1.2 brings a consistent desktop appearance and optional gaming setup,
with redesigned system tools and a simpler installed-system boot menu.

Changes

• Default ErgenOS theme for GNOME Shell, GTK3 and GTK4/libadwaita, including Nautilus.
• Redesigned ErgenPac, ErgenCTL and Welcome interfaces.
• Optional Gaming catalog: Steam, Lutris, Heroic, Faugus, GameMode, MangoHud, GOverlay and Gamescope.
• ErgenPac 1.0.1 refreshes Gaming availability automatically, including on a fresh installation.
• Hybrid AMD/Intel + NVIDIA profiles and expanded GPU diagnostics.
• ErgenCTL post-update verification integrated with ErgenPac.

Download and verification

Download the complete ISO from MediaFire.

GitHub assets contain the same ISO split into two raw parts. Download both parts,
PARTS-SHA256SUMS and ISO-SHA256SUMS into one directory, then run:

sha256sum -c PARTS-SHA256SUMS
cat ergenos-1.2.0-x86_64.iso.part01 ergenos-1.2.0-x86_64.iso.part02 > ergenos-1.2.0-x86_64.iso
sha256sum -c ISO-SHA256SUMS

Verify successfully before flashing. Do not flash the parts individually.
GitHub's automatic Source code archives are not bootable installation images.

Installation and scope

Disable Secure Boot to boot the installation media. Post-install Secure Boot
setup remains experimental. Snapshot recovery requires configured Btrfs/Snapper.

The rebuilt ISO passed maintainer VM acceptance, including Gaming and the intended
GRUB menu. Six ErgenCTL repair tests failed during an earlier container source
build and remain unresolved; this ISO uses the previously published signed
application package. VM acceptance does not represent a complete new Secure Boot
hardware regression run.

Gaming Check, guided gaming onboarding and per-game profiles are deferred to 1.3.

ErgenOS 1.1.0

ErgenOS 1.1.0

ErgenOS 1.1 strengthens system recovery, introduces guided post-install Secure Boot support and expands graphical hardware management.

Highlights

• guided Secure Boot configuration through ErgenCTL and ergenos-secureboot
• Microsoft-signed shim with a locally enrolled Machine Owner Key
• signed kernel, GRUB and installed DKMS modules
• snapshot discovery and ErgenCTL rollback through the signed Secure Boot GRUB loader
• ErgenPac Driver Manager with hardware-aware graphics driver recommendations
• reliable automatic GRUB menu refresh for newly created Snapper snapshots
• ErgenCTL 1.1.0.dev-4, ErgenPac 0.2.1 and ErgenOS Welcome 1.0.1
• optional Where Bootloader wallpaper

The complete installation, MOK enrollment, Secure Boot activation, snapshot boot and rollback workflow was validated on a physical Lenovo ThinkPad. The normal system was deliberately made unbootable and successfully restored through an ErgenCTL rollback.

Download and verification

GitHub limits individual release assets to 2 GiB, so the ISO is provided in two numbered parts. Download both parts and SHA256SUMS-1.1.0, then run:

cat ergenos-1.1.0-x86_64.iso.part-* > ergenos-1.1.0-x86_64.iso
sha256sum -c SHA256SUMS-1.1.0

Expected SHA-256:

460c2ab349681cef4922ebba35b180b24f7a17e7182dbf23cc7c99b13b1fdcce

The installation ISO must still be booted with Secure Boot disabled. Secure Boot can be enabled on the installed system by following the setup guide.
