This should show which events are sent from freerdp, maybe that helps to see what's going on. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=391778 --- Comment #14 from Martin Flöser --- The combination of the xprop and the debug output would mean that KWin is not getting the callback from our windowing system library. I checked on build.kde.org and the code area is not test covered. I'll try to add a test case. -- You are receiving this mail because: You are watching all bug changes.

There are no other messages generated ther when I start freerdp), and did not find the error "fullscreenMonitors update failed. request higher than number of screens.". -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=391778 --- Comment #11 from Martin Flöser --- What I noticed is that the xprop output is lacking the fullscreen monitor property. This should create a debug message: "fullscreenMonitors update failed. request higher than number of screens." Could someone please enable the Debug category for KWin and check xsession-errors for this message? -- You are receiving this mail because: You are watching all bug changes.

I (or more precisely a colleague) have not found another way to tell the WM to a) set a window fullscreen and b) which monitors to use for that I understand that from a WM perspective multi monitor handling is done with the randr extension and xinerama, but I could not find anything replacing this atom. I'd be more than happy to fix that in a more modern way, but the depths of X11 still have surprises whenever touched.

https://bugs.kde.org/show_bug.cgi?id=391778 armin.no...@thincast.com changed: What|Removed |Added CC||armin.no...@thincast.com --- Comment #5 from armin.no...@thincast.com --- There seem to be some misunderstandings in this issue. I'm a developer of FreeRDP, so let me clear up some things: * The 'openbox' switch is not really part of freerdp but was suggested by a contributor in that thread. This was due to another bug we had in FreeRDP with fullscreen switching, when we migrated to _NET_SUPPORTED et al. That one has already been dealt with. * There still is the `/multimon:force` switch, which forces old X11 behaviour for a WM with broken support for the new standards. (this software is used on many custom distris, some have really weired configurations) * We do support _NET_SUPPORTED, as already stated. The other paths are a fallback if the WM does not support these. * Testing this with xfreerdp is quite easy, you only need to install `xrdp` locally and connect to it with `xfreerdp /v:localhost /multimon` (++ switches between fullscreen and window mode) Maybe I'm missing something here, but I've tested the current 2.0 release candidates and master against debian and fedora with cinnamon, openbox, xfce, gnome and kde/plasma. Only kde/plasma exposes these issues. -- You are receiving this mail because: You are watching all bug changes.

I've tried to look into the source code of FreeRDP, but I have no idea of X11 Programming an gave up in the end. I'll have to wait until FreeRDP Developers fix this. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=391778 --- Comment #3 from Martin Flöser --- Furthermore I want to add that relying on the _NET_WM_FULLSCREEN_MONITORS is quite questionable. To quote the spec: "The indices are from the set returned by the Xinerama extension." Now there is just no xinerama extension used anymore. Today we use xrandr to configure multiple screens. I have no idea what these indices are that FreeRDP uses, but KWin (and probably any other window manager) doesn't know anything of Xinerama. KWin does have support for this protocol, but that's probably just for legacy support. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=391778 Martin Flöser changed: What|Removed |Added Resolution|--- |INVALID Status|UNCONFIRMED |RESOLVED --- Comment #2 from Martin Flöser --- I read through the complete bug report on github and don't see anything indicating that this is a bug in KWin. What we see in the bug report is FreeRDP having problems with fullscreen and with many, many window managers. In fact there are workarounds command line switches like "openbox". This is for me a sign that the issue must be with FreeRDP. Especially given that standard X11 functionality like checking in _NET_SUPPORTED what the WM provides has not been implemented. >From time to time it happens that bugs are reported that KWin is wrong. Every time when we investigated this, we observed, that: a) the client is wrong b) if other window managers made the client work, it was KWin implementing the specs correctly I'm sorry, but my experience tells me, that this is not a bug in KWin. If it were a bug in KWin, there would be other applications affected as well. So until someone proves me that KWin is wrong, by e.g. providing a test case which highlights the wrong behavior, I'm following my instincts and set this bug as invalid. Unfortunately I'm not able to try to reproduce to show that FreeRDP is wrong as I don't have any server to connect to. -- You are receiving this mail because: You are watching all bug changes.
