tigervnc: krdc doesn't scale vnc sessions anymore
Last modified: 2021-08-22 14:35:58 UTC
I do use scaled VNC sessions with VNC, but lately, these sessions aren't scaled anymore: they typically show sliders right and below the remote screen. It might be an krdc issue. I tried to use vncviewer, but that damaged the resolution on the remote server by default. Defining the remote resolution manually shows an unscaled desktop with sliders by default. When choosing "Adjust screen" from context menu, it reduces the remote resolution to currently the visible size. If both monitors have the same siue (2560x1600) it effectively obscures the remote menu panel, and renders the system unusable (for an average user). tigervnc: 1.10.1-14.1 krdc: 21.08.0-9.1
Are you using scaling on your display?
Yes, exactly.
Can you verify it is https://bugs.kde.org/show_bug.cgi?id=419015 ?

Well, I don't fully understand that bug, but: * I never use scaled displays locally * the deficit is in the vnc module or tigervnc, rdp sessions doesn't have a scale button The local resolution didn't change since ages, and it is never scaled. It's all about vnc connections, that used to be able to being scaled, and now, pressing the scale button doesn't do anything anymore. I cannot say, when this regression entered tumbleweed, but it's in the range of the last few month.
