  • Ported to conflicting changes in mutter 42.

  • Work in progress on a screen blanking bug.
  • Fixed warnings during screen blanking in unified buffer management for Wayland.
• Got to the bottom of Wayland sessions running at half frame rate on Nvidia Ampere cards. Looks like there’s nothing we can do about it in mutter, just wait for a fix from Nvidia.

• CUPS Snap: Waiting for @ijohnson’s pull request on snapd for the cups printing interface to get merged by the snapd team (ETA: October).
• cups-filters: Fixed bugs in texttopdf() filter function so that the universal filter function PR is ready for merging. While adding the remaining drivers to the Ghostscript Printer Application, found further bugs and fixed them: In pwgtoraster() with PPD do not modify header via IPP options (commit), parse device IDs with spaces correctly (commit)
• pappl-retrofit: Fixes on bugs discovered when working on Ghostscript Printer Application: Use device ID as display string only if manufacturer matches (commit), on driver setup skip media sources/types/sizes without PWG name to avoid crashes (commit). Also let ghostscript() filter function stream out PDF when input is Raster (commit), to allow streaming jobs on PDF printers. This is now possible as we have Ghostscript 9.55.0 which has a bug fixed. And finally wrote a little utility to support the driver information files (*.drv) with which CUPS generates PPD files also in Printer Applications. Updated README.md.
• Ghostscript Printer Application: Completed the addition of the old, often unmaintained drivers to the Snap: oki, pxljr, rastertosag-gdi, splix, brlaser, ptouch-driver. Also updated README.md. Now all regular printers with driver support in Debian are also supported by Printer Applications, the 4 Printer Applications in the Snap Store!
  OpenPrinting: On the OpenPrinting web site, added link to the Ghostscript Printer Application to the listings of the drivers which are newly added to the Snap.
• Bugs.
