Known Issues & Workarounds

Living page: entries retire as fixes roll out. Last triaged against current build stream.

Hardware-class issues

NVIDIA hybrid laptops: external display blank on Wayland sessions

Workaround: use X11 session until upstream modeset fix lands (NVIDIA Drivers on AcreetionOS); external outputs reliable there today.

Certain Realtek USB Wi-Fi dongles drop under load

Module-option tuning usually stabilizes (rtl8xxxu family) — pattern documented in Wi-Fi Setup & Troubleshooting. Firmware updates via linux-firmware resolve several variants each cycle.

Intel RST-mode laptops see no NVMe in installer

Firmware switch to AHCI required pre-install — full procedure flagged in Installation Troubleshooting (Windows-side dance included).

Software-class issues

Old cached-keyring machines fail signature checks

Not a bug — hygiene. Revival sequence in Upgrade & Migration Notes resolves permanently.

Flatpak theme mismatch on some GTK apps

Flathub runtimes lag theme releases occasionally: flatpak update first; stubborn cases take flatpak override --filesystem=xdg-data/themes style grants.

Plymouth splash flickers on some BIOS+KMS combos

Cosmetic; quiet-mode hides it. plymouth.enable=0 kernel param removes entirely if it offends.

Upstream watchlist

Tracked without local action possible yet: Cinnamon experimental-Wayland gaps (per-monitor fractional scaling edge cases), Mesa regression windows on bleeding kernels for specific GPU gens — both follow upstream fix trains automatically.

Reporting something new

Before filing: update fully, test fallback kernel, check search. Then bring evidence per Reporting Bugs Well — journal excerpts make maintainers move mountains.
