Thanks for the info, the logs don't have much though :/ The journal has that gnome-control-c[31150]: gtk_container_add: assertion 'GTK_IS_CONTAINER (container)' failed
It would be interesting to get a backtrace of that warning, unsure if you know your were around debugging enough to do that though? Basically you would need to - enable the debug packages repository as explained on https://wiki.ubuntu.com/Debug%20Symbol%20Packages and install the gnome-control-center-dbgsym libgtk-3-0-dbgsym libglib2.0-0-dbgsym at least - get a backtrace using gdb, the principle is explained on https://wiki.ubuntu.com/Backtrace but to get the one from the log you would need to "b g_log" and type "c" until you get to a call corresponding to the gtk_container_add warning If you want to try that it would be nice, if it's too technical for you that's fine Reading the description again I think the issues are 1- there is no easy way to "block" a specific ipp printer to be auto- added, which can either be a feature missing from cups or one that exists but has no UI interface, Till should know about that 2- the 'cups-pk-helper: setting default printer to Kyocera_ECOSYS_P6026cdn failed: client-error-not-found' error, which is probably a problem on the cups/cups-pk-helper side. It's weird that nothing got logged about in the journal or cups logs though... 3- the settings UI not dealing well without the 'situation' (unsure what bits are confusing it though) Does system-config-printer deal works better? Does it list the right printer and allow you to see the options or does it have issues as well? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1813825 Title: "driverless" printer workflow has bad usability/ is partly broken Status in gnome-control-center package in Ubuntu: Incomplete Bug description: Hi, since Ubuntu uses IPP ("driverless") printing, I have a bad time using printers. I don't know exactly which package this bug belongs to, I think it is gnome-control-center. I have a Kyocera EcosysP6026cdn network printer, which provides a PPD file by the manufacturer. (But I tested this behaviour as well with other printers from eg. Brother, etc., and on Debian and Arch linux too). When I switch on the printer, after a few seconds, it is found in Ubuntu and installed automatically as "Kyocera_ECOSYS_P6026cdn". So far, so good. 1) I can't remove this printer. If I WANT to install it using another protocol (dnss etc), it adds another printer, and I have 2 Printers. So it should be easy to switch off "driverless" printing. 2) Using it as "Default printer" does not work. Clicking the cog wheel, and using the menu item "Use printer by default" is clickable, but it does not save any setting: "printers-cc-panel-WARNING **: 20:45:36.812: cups-pk-helper: setting default printer to Kyocera_ECOSYS_P6026cdn failed: client-error-not-found" 3) "Printing Options" opens an empty dialog, see screenshot attached. This dialog is useless. 4) The "Printer Detail" dialog shows a "null" address and links to "(null):631", which is a 404. I think this "driverless" printing is still in a very "unstable" state. It helps discovering printers in new Networks where I attach too with my laptop, and I can print there basically, But most of the day I use my own printer in my office or at home, and I want to have my special settings for exact this printer with color profile, duplex settings etc. And this all is not possible with driverless printing. So, if you don't "fix" all the not-working options in the UI, please at least give us an option to easily switch off driverless printing at all. I really prefer the "old school" way of installing printers.
