Bug ID: 502333
Summary: Black screen after connecting with KRdp
Classification: Applications
Product: krdc
Version: 24.12.3
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: RDP
Assignee: uwol...@kde.org
Reporter: bugs.kde....@p.dobrogost.net
Target Milestone: ---
I'm getting black screen after connecting to KRdp.
Connecting to the same host from Windows 10 with Remote Desktop app works with
the caveat that after connecting, the screen is also black but then if I kill
KRdp process and it gets started automatically again by systemd (due to being
run as a service) and then I connect once more from Windows 10 it works this
time.
