Besides various improvements for the GNOME desktop environment, the Ubuntu Desktop team over at Canonical recently started to investigate the boot speed of the Ubuntu Linux operating system, planning to give it another boost by using systemd’s latest features to do some profiling, which will help them identify any issues that might cause slow boot up time. Apart from the boot speed improvements, Canonical’s Ubuntu Desktop team have discovered and fixed an issue in NetworkManager’s connectivity checker packaging, as well as to release CUPS-Filters 1.19.0, which addresses CUPS’s color space and color depth determination in the PPD generator functionality and fixes a bug to resolve 16-bit high color depth in Apple Raster.
