From f5ae26bb44c42369cbcf0a9b7da049222b5ecbf8 Mon Sep 17 00:00:00 2001 From: Olivier Fourdan Date: Fri, 10 Dec 2021 10:57:29 +0100 Subject: [PATCH 5/5] cursor-renderer/native: Add a means to disable HW cursors When dealing with a faulty hardware or bugs in the driver, it might be interesting to force the use of software cursors for debugging purposes. Add a debug environment variable MUTTER_DEBUG_DISABLE_HW_CURSORS to disable hardware cursors and force using software cursors.
