debian: apply AMD cursor fix on desktop install#34
Merged
Conversation
On AMD GPUs with GNOME/Wayland, the hardware cursor plane can be dropped on login or wake, leaving the cursor invisible until the compositor recovers. Setting MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 in /etc/environment disables atomic KMS in Mutter and prevents this. The fix is only applied when an AMD GPU is detected via lspci and is idempotent (skipped if already present in /etc/environment). Validated with bash scripts/check.sh.
