# sandbox and snap's seccomp filter denies unshare()), and disables GPU
# acceleration by default because the gpu-2404 content snap's Mesa stack
# crashes deep inside libgallium on systems with proprietary Nvidia
# drivers, and on WSL2's dxgkrnl-backed Mesa. See
# https://github.com/electron/electron/issues/48321 for the upstream
# Electron/Chromium issue covering the same crash shape.

#   snap set collabora-office enable-gpu=true

set -euo pipefail

# hasn't run yet (e.g. very first launch right after install).
