When calling "vncviewer -FullScreen localhost:N" in a context without a window manager, the screen becomes white and flashes infinitely until one kills vncviewer. Increasing the logs shows that vncviewer is looping on: Config: Set FullScreen(Bool) to on Reproducible: Always Steps to Reproduce: 1. Start Xvnc on :2 Xvnc -desktop test -SecurityTypes None -nolisten tcp -Log *:stderr:30 :2 2> /tmp/Xvnc.log & 2. Start an X session without a DM startx /bin/xterm -ls -- :1 3. Call vncviewer from the xterm in this X session vncviewer -FullScreen -Log *:stderr:100 localhost:2 2> /tmp/vncviewer-1.15-no-wm.log Hit quickly ^C to stop vncviewer. The vncviewer log shows infinitely: Config: Set FullScreen(Bool) to on Actual Results: vncviewer fails Expected Results: succeed A workaround is to call vncviewer with a DesktopSize and let the user switch to FullScreen afterwards if needed
I forgot to say that this does not happen with earlier versions of tigervnc ex: tigervnc-1.14.1-2.fc41
Can you please forward your issue to Tigervnc upstream? Upstream tracker: https://github.com/TigerVNC/tigervnc/issues
I will do. Thanks for suggesting it.
This is done: https://github.com/TigerVNC/tigervnc/issues/1936
Thank you. I will follow the upstream bug and backport the fix (if any) to Fedora.
