Subject: [PATCH 5/5] cursor-renderer/native: Add a means to disable HW cursors
|
|
|
1e895f |
|
|
|
1e895f |
When dealing with a faulty hardware or bugs in the driver, it might be
|
|
|
1e895f |
interesting to force the use of software cursors for debugging purposes.
|
|
|
1e895f |
|
|
|
1e895f |
Add a debug environment variable MUTTER_DEBUG_DISABLE_HW_CURSORS to
|
|
|
1e895f |
disable hardware cursors and force using software cursors.
|
