<div dir="ltr">Hi Michael,<div><br></div><div>I've no experience with this, but getting MRtrix3 to display over network connections can be tricky, as <a href="http://mrtrix.readthedocs.io/en/latest/getting_started/troubleshooting.html#remote-display">outlined in this page</a>. For VNC, I'd say the requirement that's most likely to be problematic is to ensure that the server can support OpenGL3.3 - and it certainly looks like the error message you posted is related to that, given the last line in particular. </div><div><br></div><div>You might find other users will be able to help, but you'd need to ask on the <a href="http://community.mrtrix.org/">MRtrix3 support forum</a> - this mailing list is for the older MRtrix 0.2 version only, and will be closed off eventually.</div><div><br></div><div>All the best,</div><div>Donald.</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On 17 September 2016 at 02:47, Michael Zeineh <span dir="ltr"><<a href="mailto:mmzeineh@gmail.com" target="_blank">mmzeineh@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>
<br>
I have mrtrix 3 running on a linux box that is running a vnc server. When I try to run while vnc’ing over, I get the error:<br>
Xlib: extension “XInputExtension” missing on display “:3.0”<br>
X Error: BadDrawable (invalid Pixmap ro Window parameter) 9<br>
Major opcode: 62 (X_CopyArea)<br>
Resource id: 0x0<br>
QGLContext::makeCurrent(): Cannot make invalid context current.<br>
<br>
Anyone run into this before or have any ideas?<br>
<br>
Thank you<br>
<br>
Michael<br>
