Question about x2goclient xinerama
by Ulrich Sibiller 14 Jul '16

14 Jul '16

Hello, while testing my xinerama re-implementation I noticed that x2goclient reports a wrong width sometimes when simply moving the window without changing the size. The reported size differs by one pixel (too much or too little). When running x2goclient --debug you can see this: x2go-DEBUG-../src/onmainwindow.cpp:10160> "New proxy geometry: (x: 329, y: 214, w: 1440, h: 900" x2go-DEBUG-../src/onmainwindow.cpp:10160> "New proxy geometry: (x: 365, y: 213, w: 1440, h: 900" x2go-DEBUG-../src/onmainwindow.cpp:10160> "New proxy geometry: (x: 825, y: 190, w: 1440, h: 900" x2go-DEBUG-../src/sshprocess.cpp:189> executing remote command via SshProcess object (24): "export DISPLAY=:50;printf '\''1095 0 345 900\n0 0 1095 900'\'' > $HOME/.x2go/C-uli-50-1431636769_stDKDE_dp24/xinerama.conf" -> here the 345 should have been a 344. Interestingly my patched x2goagent (that completely ignores xinerama.conf) sees that value. So I conclude that x2goclient is manipulating the nxproxy window size by one pixel itself. Disabling xinerama in the session's configuration fixes the problem. That off-by-one behaviour is caused by this code in onmainwindow.cpp: void ONMainWindow::slotXineramaConfigured() { if (resumingSession.fullscreen) return; if (xinSizeInc == -1) xinSizeInc=1; else xinSizeInc=-1; #ifdef Q_OS_LINUX lastDisplayGeometry.setWidth(lastDisplayGeometry.width()+xinSizeInc); XSync(QX11Info::display(),false); XResizeWindow(QX11Info::display(), proxyWinId, lastDisplayGeometry.width(),lastDisplayGeometry.height()); XSync(QX11Info::display(),false); #endif #ifdef Q_OS_WIN QRect geom; wapiWindowRect ( (HWND) proxyWinId, geom ); wapiMoveWindow( (HWND) proxyWinId, geom.x(), geom.y(), geom.width()+xinSizeInc, geom.height(),true); lastDisplayGeometry=proxyWinGeometry(); #endif xineramaTimer->start(500); } If I set xinSizeInc to zero in all cases the off-by-one behaviour is completely gone. Why does xinSizeInc exist at all? Uli

Bug#402: Numlock issues
by jordi＠amospalla.es 12 Jul '16

12 Jul '16

Package: x2goserver Version: 4.0.1.12-0x2go2+git20140108.809+wheezy.main.1 Hello, numlock does not behave correctly. It behaves like if it was randomly and continuously toggling it state. Happens when numlock key is pressed, and after some time, it seems to stabilize in some state (on or off), but it can take some time. Happens on Mate 1.6 desktop environment over Debian 6. No problem on same host with a KDE session. If numlock state is modified with numlockx binary, it works as expected, only the key triggers this. user@host:~$ while numlockx status; do sleep 0.1; done Numlock is off Numlock is off Numlock is on Numlock is on Numlock is off Numlock is on Numlock is off Numlock is on Numlock is off Numlock is on Numlock is off Numlock is off Numlock is on Numlock is on Numlock is off Numlock is on Numlock is on ...

Bug#84: DESTDIR and OPTFLAGS patches for nx-libs
by Mike Gabriel 13 Jun '16

13 Jun '16

Package: nx-libs Patches attached for nx-libs: - bin/Makefile doesn't support DESTDIR. The attached nx-libs-destdir.patch partially addresses that. - The various nx*/configure.in files do not honor passed in compiler flags. The attached nx-libs-optflags.patch fixes that. Note also though that CFLAGS is used in some and CPPFLAGS in others. ----- Weitergeleitete Nachricht von orion(a)cora.nwra.com ----- Datum: Tue, 11 Dec 2012 16:11:02 -0700 Von: Orion Poplawski <orion(a)cora.nwra.com> Antwort an: x2go-dev(a)lists.berlios.de Betreff: [X2Go-Dev] x2go for Fedora packaging issues An: x2go-dev(a)lists.berlios.de [...] Thank you for your attention. - Orion -- Orion Poplawski Technical Manager 303-415-9701 x222 NWRA, Boulder Office FAX: 303-415-9702 3380 Mitchell Lane orion(a)nwra.com Boulder, CO 80301 http://www.nwra.com ----- Ende der weitergeleiteten Nachricht ----- -- DAS-NETZWERKTEAM mike gabriel, rothenstein 5, 24214 neudorf-bornstein fon: +49 (1520) 1976 148 GnuPG Key ID 0x25771B31 mail: mike.gabriel(a)das-netzwerkteam.de, http://das-netzwerkteam.de freeBusy: https://mail.das-netzwerkteam.de/freebusy/m.gabriel%40das-netzwerkteam.de.x…

Bug#63: Current Cairo test suite segfaults x2goagent
by Moritz Struebe 13 Jun '16

13 Jun '16

Package: x2goagent Version: 3.5.0.16-0 x2goagant segfaults when running the cairo test suite. (The current version only compiles on Wheezy) This can be reproduced running: git clone git://anongit.freedesktop.org/git/cairo cd cairo ./autogen.sh ./configure make make test As quite few tests fail Bugs #62 and #35 might be related to Cairo.

Bug#78: NX_xrandr lacks support from Xrandr 1.2 and higher
by Reinhard Tartler 13 Jun '16

13 Jun '16

Package: x2goagent When starting a new x2go session, the startup scripts modify the LD_LIBRARY_PATH of all applications to include /usr/lib/nx/X11/Xrandr. This replaces the system libXrandr with the NX/X2go provided one. Unfortunately, this breaks the xrandr utility: >> echo $LD_LIBRARY_PATH /usr/lib/nx/X11/Xrandr:/usr/lib/nx/X11/Xinerama:/usr/lib/nx/X11 >> xrandr xrandr: symbol lookup error: xrandr: undefined symbol: XRRGetScreenSizeRange zsh: exit 127 xrandr -- regards, Reinhard

Bug#908: nxagent segfault, causes session loss
by Rob Izzard 13 Jun '16

13 Jun '16

Package: nxagent Version: 3.5.0.32-0~668~ubuntu14.04.1 Severity: important Dear nxagent coders, Over the last couple of weeks I have lost a few x2go sessions which is, you can imagine, annoying. I thought it was just a rare bug and I was unlucky, but today it happened again so I have collected what I can. It seems that when I try to connect to a running session there is *sometimes* a crash of nxagent. Not always, but when it happens x2go terminates the session. I do not know why x2go terminates the session - surely it should allow me to retry the connect? Anyway, everything in that session is lost, so this problem is fatal as well as annoying. The connection is to localhost, so there's no network failure (despite the suggestion of the error message). I hope this isn't a problem with the latest nx 3.5.0.32 ... :-/ please let me know how I can help any further. many thanks!

Bug#838: control-alt-arrow keys
by Robert Dinse 24 Feb '16

24 Feb '16

Package: x2goagent I am using Ubuntu 14.10 with Mate Desktop with multiple work spaces. If I use Remmina with NX plugin, the control-alt-right/left arrow keys work to switch work spaces even when I'm up on a remote desktop. With X2Go, it usually doesn't work, except if I use control-alt-M to minimize the session then restore it, the keys will usually work thereafter. Remmina has a way to toggle this behavior, a little pull down at the top with a keyboard symbol. If it's down, the control-alt-arrows go to the end application allowing me to switch work spaces on the remote desktop, and if it's up they go to the local desktop. It would be nice if x2go had a similar facility but if not it would be better for that key sequence to always act locally since I can switch work spaces remotely by using the mouse but can not locally because the switcher is hidden by the remote desktop x2go is displaying. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.
