Canonical's high-yield developer Daniel Van Vugt shared the progress of two important projects he is responsible for in the weekly development progress: supporting dark mode and providing three-level cache.
The Linux desktop has been lagging behind Windows and macOS in dark support. For several months, Daniel has been focusing on providing dark support for Ubuntu. Initially, he suffered a setback because the changes were more intrusive than he expected. These changes involve a lot of content. Judging from the progress of Daniel's latest release, some progress has been made in dark support. He resolved the issue that affected support for dark mode in the past week and is now waiting for more tests.
Dynamic L3 cache is another function that Daniel is responsible for. Its motivation is to dynamically perform L3 cache when needed, so that the GPU can speed up its clock frequency, otherwise its rendering efficiency will slow down. Making the GPU work faster and temporarily causing additional frame delays is not ideal, but it does seem to improve GPU performance when needed.
In the past week, Daniel modified the code on the third-level cache, and is currently compatible with his upcoming NVIDIA delayed repair work and related changes, as well as further testing and updated documentation.
If these two functions can be reviewed in time, they are expected to be added in GNOME 40, which will be released tomorrow spring.
Ubuntu Discourse provides a detailed discussion of these progress.
