Dear Experts,

Thanks!  My years of working with macs meant I didn't have to call fsleyes this way.

So, the good news, that works, fsleyes starts when I type FSLeyes.

The machine I'm working on is a VM of Ubuntu 16.04.3 Neurodebian is installed and was used to install fsleyes.

The bad news is that when I try to start FSLeyes from the virtual desktop, I see the splash screen and then it 

crashes and I get the following error:

   ERROR              main.py  383: initialise      - Unable to initialise OpenGL!

Traceback (most recent call last):

  File "/usr/lib/python2.7/dist-packages/fsleyes/main.py", line 380, in initialise

    fslgl.getGLContext(parent=splash, ready=realCallback)

  File "/usr/lib/python2.7/dist-packages/fsleyes/gl/__init__.py", line 433, in getGLContext

    thismod._glContext = GLContext(*args, **kwargs)

  File "/usr/lib/python2.7/dist-packages/fsleyes/gl/__init__.py", line 574, in __init__

    self.__createWXGLCanvas()

  File "/usr/lib/python2.7/dist-packages/fsleyes/gl/__init__.py", line 675, in __createWXGLCanvas

    self.__canvas.SetSize((0, 0))

  File "/usr/lib/python2.7/dist-packages/wx-3.0-gtk2/wx/_core.py", line 9334, in SetSize

    return _core_.Window_SetSize(*args, **kwargs)

PyAssertionError: C++ assertion "m_widget" failed at ../src/gtk/window.cpp(2831) in DoSetSize(): invalid window

============

XWindows Approach:

I then tried using Xwindows.  I can invoke the fsl gui, afni and several other tools with XWindows, so I figured it was okay.

FSLeyes is not happy though (same thing, splash screen-->crash):

diannepat@vm142-98:~$ FSLeyes

libGL error: No matching fbConfigs or visuals found

libGL error: failed to load driver: swrast

The program 'FSLeyes' received an X Window System error.

This probably reflects a bug in the program.

The error was 'BadValue (integer parameter out of range for operation)'.

  (Details: serial 688 error_code 2 request_code 149 minor_code 24)

  (Note to programmers: normally, X errors are reported asynchronously;

   that is, you will receive the error a while after causing it.

   To debug your program, run it with the --sync command line

   option to change this behavior. You can then get a meaningful

   backtrace from your debugger if you break on the gdk_x_error() function.)

==============

Any suggestions welcome.

Thanks so much,

Dianne

Dear All, 

I am setting up an Ubuntu 16.04 machine with neurodebian. I had installed fsl-complete but apparently this did not include fsleyes.

Today I ran 

>sudo apt-get install fsleyes

However, I cannot tell where it installed or how to start it. Can anyone give me any pointers?

Thanks,

Dianne
