[winswitch] Xpra has side effects on Cinnamon

[develop_at_Sophtwearteam]

Hello Everyone,

Does anyone has faced issues with cinnamon desktop environment? As a
member of a Linux User Group we had recently some nasty experiences
while examining Xpra and it's functions.

One has Linux Mint installed on his machine with Cinnamon desktop
(details at the bottom) and another installation is mine:
System:
  Kernel: 5.7.6-201.fc32.x86_64 x86_64 bits: 64 Desktop: Cinnamon 4.6.5
  Distro: Fedora release 32 (Thirty Two)
Machine:
  Type: Laptop System: LENOVO product: 20FB006BGE v: ThinkPad X1 Carbon 4th
Graphics:
  Device-1: Intel Skylake GT2 [HD Graphics 520] driver: i915 v: kernel
  Device-2: Chicony Integrated Camera type: USB driver: uvcvideo
  Display: x11 server: Fedora Project X.org 1.20.8 driver: modesetting
  unloaded: fbdev,vesa resolution: 2560x1440~60Hz
  OpenGL: renderer: Mesa Intel HD Graphics 520 (SKL GT2) v: 4.6 Mesa 20.1.2

Issue here was: After reopening the lid of the laptop and resume from
suspend, the login screen was not showing the password field, but a kind
of desktop without any functionality. By entering the password as usual
('blind' in this case, because it wasn't shown because of missing
password entry field) and hitting the ENTER button, the login succeeded
and the desktop was still usable as expected.

After removing Xpra from the system, everything was back to normal.

The case of my friend with his Mint machine was way worse. After Xpra
not reacting anymore, he decided to remove (purge) the software from his
system. Then he did a reboot of his machine and ran into rescue mode
with no Xwindow / Xorg working anymore. After reinstalling the Xwindow /
Xorg packages and reboot he could relogin graphically. Back to business.

Two other guys with opensuse Tumbleweed installations and KDE had also
some minor issues. One couldn't start the Xpra program at all after
installation and had some updates left. The other one didn't get the
clue, so this might be another problem.

All installations came from the repositories of their distributions. No
foreign repos where used.

This led us to the conclusion not to install and run Xpra anymore.

I would have had reported a bug, but after removing Xpra from the system
and my riders did it as well, we cannot provide any useful data than
mine here in the top of this mail.

Hope you can keep this in mind if anyone else report bugs similar to this.

Have a nice day
stippi
