3.4.6 Problems running Fireworks

Complete: 5

OpenGL and X11 problems

Indirect (remote) rendering disabled by default in newer XOrg versions (including XQuartz)

The error shows up like this:

xuser@remote.machine (~ ): glxgears
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  150 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  23
  Current serial number in output stream:  24

This can be fixed by adding the +iglx option to the line that starts the X server on the local machine. There is currently no configuration file option (it will be added to xorg-1.19 and probably backported to older versions).

Install XQuartz or make sure it is not running. After the installation run the following command:

defaults write org.macosforge.xquartz.X11 enable_iglx -bool true
You may find you need to reboot your machine to have that take effect. Also note that XQuartz installation requires logout/log back in after installation for its changes to take effect.

this depends on a distribution, for Ubuntu see the link below. We will update this entry for other distributions as needed. Replacing /usr/bin/xorg with a script should work everywhere, as descibed here hard hack (substitute -ignoreABI with +iglx).

Running remotely on CC7 machines (also lxplus7.cern.ch)

There is a problem with the Mesa GL version on lxplus (probably all CC7 machines) that manifests as SEGV in LLVM pipeline during early stage of Fireworks startup:

#4  <signal handler called>
#5  0x00007fab213cf5ba in __memcpy_ssse3_back () from /lib64/libc.so.6
#6  0x00007fab09412bdb in llvm::WritableMemoryBuffer::getNewUninitMemBuffer(unsigned long, llvm::Twine const&) () from /usr/lib64/libLLVM-6.0-rhel.so
#7  0x00007fab09412caf in getMemBufferCopyImpl(llvm::StringRef, llvm::Twine const&) () from /usr/lib64/libLLVM-6.0-rhel.so
#8  0x00007fab09412d30 in llvm::MemoryBuffer::getMemBufferCopy(llvm::StringRef, llvm::Twine const&) () from /usr/lib64/libLLVM-6.0-rhel.so

Setting the following environment variables disables usage of LLVM renderer in Mesa GL:

export GALLIUM_DRIVER=softpipe
export DRAW_USE_LLVM=0

Running remotely on SLC6 machines (lxplus6.cern.ch)

If cmsShow crashes with the following error when running remotely (via ssh):

Error: couldn't find RGB GLX visual or fbconfig
This is due to a bug in mesa implementation shipped with SLC6; it manifests with newer versions of xorg server and newer OpenGL drivers provided by NVIDIA. The problem will be fixed in SLC6 in the future, but in the meantime you can bypass the problem by disabling hardware rendering:

Linux specific issues

Buggy Intel drivers

On board Inter graphic drivers are known to be buggy. To check if this is the case run lspci and look if there is intel graphic card listed. Also check glxinfo to get list of GL extensions (should be 50 or more of them). Try to disable hardware rendering with LIBGL_ALWAYS_INDIRECT environment variable:

Alternatively you can use cmsShow option --soft, which exports the same environment variable.

If you still have problems and glxgears run without errors, send output of lspci, glxinfo, and dpyinfo to fireworks support mailing list (hn-cms-visualization@cernNOSPAMPLEASE.ch).

Window refresh does not work properly

  • On some window managers window refresh does not work properly. For example if Fireworks window is covered by another window, the window stays black after the covering window is removed. To fix the problem open file /etc/X11/xorg.conf and remove line Option "BackingStore" "on" in the Device section. Restart X session when finish changes in xorg.conf file.

Ubuntu shows only empty graphics views

  • The advanced window manager now default in Ubuntu interferes with OpenGL programs. The problem can be fixed by going to System Preferences -> Appearances -> Visual Effects and set the option to None

Mac OS specific issues

  • XQuartz 2.7.10 or later required for 8x mac tarball

    The following error is printed with 2.7.8 or older:

    ./cmsShow data.root 
    dyld: Library not loaded: /opt/X11/lib/libXt.7.dylib
      Referenced from: /Users/alja/cms-dev/standalone/cmsShow-8.1/libexec/cmsShow.exe
      Reason: image not found
  • Visuals problems. If you see the following error printed to the terminal after running cmsShow
    Error in <TGLWidget::CreateGLContainer>: No good visual found!
    terminate called after throwing an instance of 'std::runtime_error'
    what(): No good visual found!

    Then probably you have restricted the number of colors X11 is allowed to use. To change this do the following:
    1. Make X11.app the active application
    2. Choose the menu item X11->Preferences...
    3. In the preference dialog choose the Output tab
    4. In the selection box next too Colors: make sure to select From Display
    5. Restart X11.app

Older Mac OS issues

  • X11 problems. Sometimes X11 may crash or get in some strange state and the event display just doesn't do anything getting stuck when it starts. Kill both the event display and X11 program and try to run the display one more time.
  • Apple update for osx-10.7 (Lion) released in Sep/Oct 2012 causes a consistent resurgence of the above problem!
    Apparently this update causes a break between OpenGL and the X11 application provided by 10.7. Installation of the latest XQuartz X-server solves the problem. It's a seamless install, you just need to log off and back on after the installation.

Problems saving images

FBO error saving into png/gif files

When save image into png or gif file, you can get the following error:
Error in <TGLEmbeddedViewer::TGLViewer::SavePictureUsingFBO>:
TGLFBO::Init maximum size supported by GL implementation is 0.

The problem is a consequence of false information in GL query. You can avoid the problem by using system tools to create screenshot or to disable FBO in your .rootrc file, by adding the following line:

OpenGL.SavePicturesViaFBO: false

Pdf and ps format

Save to pdf or ps file formats is not supported and will be removed as an option from ROOT file dialog. It is not supported because transparent object and textures are not correctly converted. If you need pdf, the convert command from ImageMagick tools can create a pdf encapsulating the binary image.

Alternatives to save image into file

  • Linux All linux distibution ship xwd command line tool to capture an image. Bellow are two examples of usage:
         xwd  -root | convert - screenshot1.png
         xwd  | convert - screenshot1.png
  • Mac
    Command-Shift-3 :Take a screenshot of the screen, and save it as a file on the desktop
    Command-Shift-4, then select an area: Take a screenshot of an area and save it as a file on the desktop
