It seems that cairo unconditionally assumes that the xserver does support the latest version of the Xrender extension: http://cgit.freedesktop.org/cairo/tree/src/cairo-xlib-display.c?id=1.12.2#n… This assumption does not hold for many non-Xorg Xservers, including nxagent, which is used by NX and derivatives like OpenNX, FreeNX or X2Go: http://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=nx-X11/include/extension… Note that the defines for Operators only available in version 0.11 in Xorg are *not* included: /* * Operators only available in version 0.11 */ #define PictOpBlendMinimum 0x30 #define PictOpMultiply 0x30 #define PictOpScreen 0x31 #define PictOpOverlay 0x32 #define PictOpDarken 0x33 #define PictOpLighten 0x34 #define PictOpColorDodge 0x35 #define PictOpColorBurn 0x36 #define PictOpHardLight 0x37 #define PictOpSoftLight 0x38 #define PictOpDifference 0x39 #define PictOpExclusion 0x3a #define PictOpHSLHue 0x3b #define PictOpHSLSaturation 0x3c #define PictOpHSLColor 0x3d #define PictOpHSLLuminosity 0x3e #define PictOpBlendMaximum 0x3e Also, note that nxagent does not use pixman (which is the software implementation that Xorg uses nowadays), but the old, previous implementation of low-level pixel rendering, AFAIUI for example: http://code.x2go.org/gitweb?p=nx-libs.git;a=blob;f=nx-X11/programs/Xserver/… I would assume that there are still a number of other non-Xorg X11 servers (most of them commercial) that do not support these operations. Chris, is there any chance to fix/change cairo to work also without operators that are only available in version 0.11? -- Gruesse/greetings, Reinhard Tartler, KeyID 945348A4

Bug#81: get rid of remnant html tags in client<->broker communications
by Mike Gabriel 07 Dec '12

07 Dec '12

Package: x2goclient Severity: normal Version: 3.99.3.1-HEAD Tags: patch confirmed Hi Alex, I have taken a closer look at the httpbrokerclient.cpp code in x2goclient. Most replies from the httpbroker are compliant with a text/plain content type. This is good IMHO. However, in HttpBrokerClient::createIniFile x2goclient expects html tags as line breaks. If these tags are missing, the session profile won't get recognized by x2goclient. With the current developmental code in x2gobroker.git, I try to implement the current broker API with no html elements at all, so I'd be happy if these last required s could be made unnecessary. Currently, as a list of session profiles the httpbroker client code in x2goclient expects some broker output like this: """ START_USER_SESSIONS [b00830a9-aec4-4e9e-88f8-ddbffeb1c8ea]defsndport=1 sndport=4713 xinerama=1 variant= useiconv=0 iconvfrom=UTF-8 height=600 usekbd=1 applications=TERMINAL,WWWBROWSER,MAILCLIENT,OFFICE host=localhost export= user= fstunnel=1 quality=9 sshport=22 sound=1 fullscreen=0 rootless=0 layout= name=LOCALHOST sshproxyport=22 soundsystem=pulse speed=2 iconvto=UTF-8 soundtunnel=1 useexports=1 width=800 command=KDE multidisp=0 print=1 setdpi=0 type=auto dpi=96 pack=16m-jpeg END_USER_SESSIONS """ So, I am quite keen on x2goclient being able to _also_ handle broker output that looks like this, instead: """ [47af8619-d619-43de-bf00-2c30c47772d1] defsndport=1 sndport=4713 xinerama=1 variant= useiconv=0 iconvfrom=UTF-8 height=600 usekbd=1 applications=TERMINAL,WWWBROWSER,MAILCLIENT,OFFICE host=localhost export= user= fstunnel=1 quality=9 sshport=22 sound=1 fullscreen=0 rootless=0 layout= name=LOCALHOST sshproxyport=22 soundsystem=pulse speed=2 iconvto=UTF-8 soundtunnel=1 useexports=1 width=800 command=KDE multidisp=0 print=1 setdpi=0 type=auto dpi=96 pack=16m-jpeg END_USER_SESSIONS """ Attached to this post you find a patch against httpbrokerclient.* that makes x2goclient understand both variants of httpbroker output (IMHO). Can you please cross-check if that patch keeps x2goclient working with all other broker implementations that are currently deployed at your customers' sites?

Bug#79: x2goruncommand is not "user friendly"
by Reinhard Tartler 06 Dec '12

06 Dec '12

Package: x2goserver It seems that x2goruncommand is not supposed to be called directly by the user. Calling it without parameters yields to: >> x2goruncommand /usr/bin/x2goruncommand: Zeile 46: /home/inf4/tartler/.x2go/C-/cmdoutput: Datei oder Verzeichnis nicht gefunden /usr/bin/x2goruncommand: Zeile 262: /home/inf4/tartler/.x2go/C-/cmdoutput: Datei oder Verzeichnis nicht gefunden kill: Gebrauch: kill [-s Signalname | -n Signalnummer | -Signalname] [pid | job] ... oder kill -l [Signalname] Died at /usr/lib/x2go/x2gochangestatus line 35. argument "session_id" missed at /usr/lib/x2go/x2godbwrapper.pm line 575. The fact that it is installed by default into /usr/bin makes it appear in the tab-completion of modern shells such as bash and implies that users are supposed to call it directly. I would suggest to either: a) make it robust against wrong calling usage, b) place it in /usr/lib/x2go/x2goruncommand instead, or c) both. -- regards, Reinhard

Bug#35: Reproducible on wheezy and quantal
by Reinhard Tartler 06 Dec '12

06 Dec '12

I can reproduce this problem with both Debian/wheezy and Ubuntu/quantal. Downgrading to libcairo 1.10 makes the fonts readable again. This is not an acceptable solution, as this cannot be done without breaking package dependency constraints. -- regards, Reinhard
