<div dir="ltr"><div><div><div>Hi Anna,<br>Hi all,<br><br></div>to report back. I know successfully built and installed wxPython3. Subsequently I rebuilt and installed GRASS7<br></div>based on the newest revision. Here my system and version output:<br>

<div>Here some output from the Python Shell that may or may not be helpful:<br><br>import wx<br>import wxversion<br>wx.glcanvas.GLCanvas_IsDisplaySupported([0,16,24,32])<br>False<br>wx.glcanvas.GLCanvas_IsDisplaySupported([0])<br>

<div>import wx</div><div>wx.version()</div><div><br></div><div>In wxPython >= 2.9, there is a method IsDisplaySupported which would help to understand more about the problem [1]. The only thing which I know you could try is to install wxPython 3. You can either compile it yourself or update Ubuntu to the latest one and install the package. However I can't guarantee it helps.</div>

However when I change to the 3d view (WxNviz) nothing is rendered, instead I get the message that I should try a different depth buffer number. This procedure is also mentioned in the wiki (<a href="http://grasswiki.osgeo.org/wiki/WxNviz" target="_blank">http://grasswiki.osgeo.org/wiki/WxNviz</a>).<br>
</div>However, I tried now all possible numbers (0,16,24,32) saved the preferences and restarted the gui with the new settings but the problem persists (BTW, the possible number 0 is mentioned in the wiki but not in the preferences GUI).<br>
<br></div>I am not sure what is causing the problem in my case. Here I just need to mention that I am working on a slightly special set up. GRASS is running on a virtual Ubuntu machine (via VMWare) which is installed on a central multi core machine (Intel® Xeon(R) CPU X5675 @ 3.07GHz × 8, Ubuntu 12.04, 32 bit). I connect to the virtual machine via a remote desktop connection (RDP connection) from a so called thin-client.<br>
<br>My GRASS setup as follows: <br>version=7.0.svn<br>date=2014<br>revision=59321M<br>build_date=2014-03-25<br>build_platform=i686-pc-linux-gnu<br>libgis_revision=59317 <br>libgis_date="2014-03-24 20:38:32 +0100 (Mon, 24 Mar 2014) "<br>
proj4=4.8.0<br>gdal=1.10.0<br>geos=3.3.8<br>sqlite=3.7.9<br><br><br></div><div>Does anyone have a suggestion how to deal with that problem or how to find out where the exact problem (remote connection, Ubuntu, GRASS) is located?<br>
