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.
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.
