Bug#402: Related issue in Ubuntu MATE...
by Mike Gabriel 10 Jul '16

This issue (#402) is probably more a MATE upstream problem then an X2Go issue itself...

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#150: Cinnamon 2.2 does not work
by Michael DePaulo 20 Feb '16

20 Feb '16

I just tested Cinnamon 2.2.13 and it does not work properly with X2Go. Basically, Cinnamon resorts fo "fallback mode", which is not the same as Cinnamon2d. More details are below. Note that GLX is enabled, and I ran the "Custom Desktop" command: cinnamon-session-cinnamon2d ---- When I connect, only gnome-panel is running. (Basically, gnome-flashback is running, although package gnome-session-flashback is not installed) It is very different from cinnamon2d, which works locally, and there are many bugs in this version of gnome-panel/gnome-flashback. For example, you cannot even set a desktop background using the GUIs. I also see a dialog with the text: Do you want to restart Cinnamon? Cinnamon just crashed. You are currently running in Fallback Mode. If I click yes, the dialog comes back up. If I click No, I the dialog closes, and the session is usable, but it's very buggy for aforementioned reasons. This is just a VM I setup for the specific purpose of testing Cinnamon compatibility with X2Go. I have the GLX extension enabled on my test system (/etc/x2go/x2goagent.options has the line to disable GLX commented out) - Linux mint 17 qiana (based on Ubuntu 12.04 trusty) 64-bit - All latest level 1, 2 and 3 OS updates installed. - cinnamon version 2.2.13 - Custom Desktop specified in x2goclient: cinnamon-session-cinnamon2d - x2goserver & x2goserver-xsession: 4.0.1.15-0~847~ubuntu14.04.1 - nxagent & x2goagent: 2:3.5.0.27-0~446~ubuntu14.04.1 I've attached the contents of my .xsession-x2go-errors file. Note the following session files: batmin@mint-q /usr/share/cinnamon-session/sessions $ ls cinnamon2d.session cinnamon.session batmin@mint-q /usr/share/cinnamon-session/sessions $ cat cinnamon2d.session [Cinnamon Session] Name=Cinnamon (Software Rendering) RequiredComponents=cinnamon;cinnamon-settings-daemon;cinnamon-screensaver;nemo-autostart;nm-applet; DesktopName=X-Cinnamon batmin@mint-q /usr/share/xsessions $ ls cinnamon2d.desktop cinnamon.desktop batmin@mint-q /usr/share/xsessions $ cat cinnamon2d.desktop [Desktop Entry] Name=Cinnamon (Software Rendering) Comment=This session logs you into Cinnamon (using software rendering) Exec=cinnamon-session-cinnamon2d TryExec=/usr/bin/cinnamon2d Icon= Type=Application X-Ubuntu-Gettext-Domain=cinnamon X-GNOME-Provides=cinnamon2d batmin@mint-q /usr/share/xsessions $ cat /usr/bin/cinnamon-session-cinnamon2d #! /bin/sh exec cinnamon-session --session cinnamon2d "$@"

Bug#707: BPG as bitmap compression engine in NX
by Mike Gabriel 20 Feb '16

20 Feb '16

Package: libxcomp3 Severity: wishlist Hi all, By Savko Sergey I have just been pointed to the upcoming BPG image compression library [1]. Quoting their website: """ BPG (Better Portable Graphics) is a new image format. Its purpose is to replace the JPEG image format when quality or file size is an issue. Its main advantages are: High compression ratio. Files are much smaller than JPEG for similar quality. Supported by most Web browsers with a small Javascript decoder (gzipped size: 55 KB). Based on a subset of the HEVC open video compression standard. Supports the same chroma formats as JPEG (grayscale, YCbCr 4:2:0, 4:2:2, 4:4:4) to reduce the losses during the conversion. An alpha channel is supported. The RGB, YCgCo and CMYK color spaces are also supported. Native support of 8 to 14 bits per channel for a higher dynamic range. Lossless compression is supported. Various metadata (such as EXIF, ICC profile, XMP) can be included. """ We should take a look at this new compression library and check if it is usable in NX.

Bug#769: pyhoca-gui gtk3 support
by Orion Poplawski 26 May '15

Package: pyhoca-gui Version: 0.5.0.3 Fedora rawhide is in the process of moving to wxPython 3.0 with gtk3 support. This appears to be breaking pyhoca-gui: /usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_boxed_type_register_static: assertion 'g_type_from_name (name) == 0' failed from gtk import _gtk /usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_set_qdata: assertion 'node != NULL' failed from gtk import _gtk /usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40: Warning: cannot register existing type 'GtkWidget' from gtk import _gtk /usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_add_interface_static: assertion 'G_TYPE_IS_INSTANTIATABLE (instance_type)' failed from gtk import _gtk /usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40: Warning: cannot register existing type 'GtkBuildable' from gtk import _gtk /usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_interface_add_prerequisite: assertion 'G_TYPE_IS_INTERFACE (interface_type)' failed from gtk import _gtk /usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_once_init_leave: assertion 'result != 0' failed from gtk import _gtk /usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:40: Warning: g_type_register_static: assertion 'parent_type > 0' failed from gtk import _gtk I believe this is because we are mixing a gtk2 based notify-python module with the gtk3 wxPython module. This seems like further impetus to move to a modern python libnotify interface, either notify2 or gobject introspection Notify. Code difference for gi appears to be: diff --git a/pyhoca/wxgui/notify.py b/pyhoca/wxgui/notify.py index bc49028..85f0d52 100644 --- a/pyhoca/wxgui/notify.py +++ b/pyhoca/wxgui/notify.py @@ -22,7 +22,7 @@ import wx from x2go import X2GOCLIENT_OS from x2go import log if X2GOCLIENT_OS in ('Linux', 'Mac'): - import pynotify + from gi.repository import Notify import exceptions import basepath @@ -52,7 +52,7 @@ class libnotify_NotifierPopup(object): self._PyHocaGUI = _PyHocaGUI self._pyhoca_logger = self._PyHocaGUI._pyhoca_logger - if not pynotify.init("PyHocaGUI"): + if not Notify.init("PyHocaGUI"): raise NotSupportedException def prepare(self, context, title=None, text=None, icon=None, timeout=None): @@ -132,8 +132,8 @@ class libnotify_NotifierPopup(object): try: if not self._PyHocaGUI.disable_notifications and title and text: - n = pynotify.Notification(title, text, icon) - n.set_urgency(pynotify.URGENCY_NORMAL) + n = Notify.Notification.new(title, text, icon) + n.set_urgency(Notify.Urgency.NORMAL) n.set_timeout(timeout) n.show() except: Although with that change, unless I comment out the set_urgency() call, I don't see the message "SSH key authentication has been successful." pop-up above the pyhoca-gui icon.
