Next reboot, right back at square one where colord only picks up one monitor and the printer until I reinstall colord, and once I do that I can see both monitors but not the printer... *SIGH* -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to colord in Ubuntu. https://bugs.launchpad.net/bugs/1934409 Title: Only one monitor showing in Color Corrections - System Settings Module Status in colord package in Ubuntu: New Bug description: I just made the switch to 21.04, and I've immediatly run into problem with color corrections. In the Color Correction - System settings Module, I can only see and apply a color profile to my first display on the first display port (DP0). My second display on the 2nd display Port (DP1) is not shown, so I'm unable to apply a color profile to make the two monitors look identical.
