>From my Windows computer, I used Winswitch to start a cairo-dock application session via xpra.
The result is a Mac-like launcher on a Windows desktop (& the launcher will the launch my server's
Here is a link to my setups, screenshots and some resources:
Below is a further report on the winswitch/xpra crash I am experiencing (I sent it earlier from the
wrong email address, so it is stuck in the moderator cue ...)
Actually, even with the ffmpeg installed, I still get the crashes. Does not happen every time, but
I am not certain what is the difference. Here is the last sequence:
1. reboot computer.
2. start winswitch
3. start application "Caligra KDE help" in Xpra via winswitch menu. (This was just a random selection.)
4. Close Caligra help window by clicking x in corner.
5. An xpra icon remains in tray -- not sure what these are, but I routinely have one xpra session in
tray that does not seem to be related to any actual session.
6. Close Winswitch
Result: black screen, blinking cursor, computer unresponsive except to <ctrl><alt><delete> (which
drops to runlevel 3 and reboots computer).
Lenovo Yoga2 Pro x86_64, quad density screen, intel i7
OpenSuSE 13.2 + Linux 4.0.x kernel
(rpms for both built on same machine that is crashing).
This does not happen on my other computer, running rpms built from the same spec files, setup as
HP AMD x86_64 desktop
OpenSuSE 13.1 (linux kernel 3.16.x I think, whichever is standard for openSuSE 13.1)
(opSU 13.1 rpms built on this machine)
