Subject: [PATCH 5/9] backends/native: emit gl-video-memory-purged when
|
|
|
776610 |
becoming active
|
|
|
776610 |
|
|
|
776610 |
The proprietary NVIDIA driver garbles memory on suspend. In order
|
|
|
776610 |
to work around that limitation, mutter needs to refresh all its
|
|
|
776610 |
textures on resuem.
|
|
|
776610 |
|
|
|
776610 |
This commit lays the way toward doing that by emitting the
|
|
|
776610 |
"gl-video-memory-purged" signal when the compositor becomes active
|
|
|
776610 |
by logind (which happens on VT switch and on resume).
