Bug description
I am reporting a screenshot-key regression in Cinnamon 6.4.14. Before the update, I could use Shift+Print to launch the familiar GNOME Screenshot interface and select an area. After updating, Cinnamon began intercepting the Print Screen key and launching its own capture function instead.
System information:
Computer: GEEKOM A8
Desktop: Linux Mint Cinnamon
Cinnamon version: 6.4.14
Session type: X11
Screenshot application: gnome-screenshot
My update history shows that Cinnamon was upgraded from version 6.4.8 to 6.4.14 during the same update operation that installed a new kernel. I tested the previous kernel, but the problem remained, so this does not appear to be a kernel regression.
GNOME Screenshot itself works correctly when started from a terminal:
/usr/bin/gnome-screenshot --interactive
The problem occurs when attempting to assign that command to Shift+Print. Cinnamon continues to intercept the Print Screen key before the custom shortcut can run.
I performed the following troubleshooting:
Disabled Cinnamon’s built-in screenshot bindings, including screenshot, screenshot-clip, area-screenshot, and related window bindings.
Created a valid Cinnamon custom shortcut using custom3 with:
/usr/bin/gnome-screenshot --interactive
Confirmed that the custom shortcut was stored correctly in dconf.
Logged out and back in after changing the bindings.
Disabled and tested xbindkeys; it was not responsible.
Confirmed that only csd-media-keys was running as the media-key daemon.
Attached strace to both Cinnamon and csd-media-keys; no external screenshot executable was launched when Print was pressed.
Queried the owner of the screenshot D-Bus service with:
busctl --user status org.gnome.Shell.Screenshot
The result identified Cinnamon itself:
Comm=cinnamon
Exe=/usr/bin/cinnamon
CommandLine=cinnamon --replace
Even with all configurable Cinnamon screenshot bindings cleared, pressing Print still activates Cinnamon’s internal screen capture. Cinnamon’s shortcut editor also cannot reliably capture the Print key because the internal screenshot handler receives it first.
This behavior prevents users from assigning Print or Shift+Print to their preferred screenshot application. It also makes the shortcut settings misleading because the displayed configuration says the bindings are disabled while Cinnamon continues to act on them.
Please investigate Cinnamon 6.4.14’s internal handling of the Print Screen key. The desktop should respect disabled screenshot bindings and allow custom shortcuts to receive Print-key combinations. I would appreciate either a fix or clear instructions for disabling Cinnamon’s internal screenshot handler.
