    <p>I have a Qt executable file. When this program runs on a Ubuntu 11.04 virtual machine, the GUI is ugly though you can still tell it is the GUI that you want. When it runs on Ubuntu 12.04 of my laptop, however, everything goes well. Thus I guess there might be something wrong with the environment of the virtual machine.</p> <p>To find out whether the problem lies in the libraries, I ran the command</p> <pre><code>ldd filename </code></pre> <p>I got library dependencies as following:</p> <pre><code>% Below is the output on the virtual machine linux-gate.so.1 =&gt; (0x00cc8000) libQtGui.so.4 =&gt; /opt/qt-4.7.1x86/lib/libQtGui.so.4 (0x00cc9000) libQtCore.so.4 =&gt; /opt/qt-4.7.1x86/lib/libQtCore.so.4 (0x00110000) libpthread.so.0 =&gt; /lib/i386-linux-gnu/libpthread.so.0 (0x003b6000) libstdc++.so.6 =&gt; /usr/lib/i386-linux-gnu/libstdc++.so.6 (0x003cf000) libm.so.6 =&gt; /lib/i386-linux-gnu/libm.so.6 (0x004ba000) libgcc_s.so.1 =&gt; /lib/i386-linux-gnu/libgcc_s.so.1 (0x004e0000) libc.so.6 =&gt; /lib/i386-linux-gnu/libc.so.6 (0x004fc000) libXext.so.6 =&gt; /usr/lib/i386-linux-gnu/libXext.so.6 (0x00686000) libX11.so.6 =&gt; /usr/lib/i386-linux-gnu/libX11.so.6 (0x00695000) libdl.so.2 =&gt; /lib/i386-linux-gnu/libdl.so.2 (0x0065d000) librt.so.1 =&gt; /lib/i386-linux-gnu/librt.so.1 (0x007b0000) /lib/ld-linux.so.2 (0x00668000) libxcb.so.1 =&gt; /usr/lib/i386-linux-gnu/libxcb.so.1 (0x00a96000) libXau.so.6 =&gt; /usr/lib/i386-linux-gnu/libXau.so.6 (0x009ed000) libXdmcp.so.6 =&gt; /usr/lib/i386-linux-gnu/libXdmcp.so.6 (0x008a8000) % Below is the output on Ubuntu 12.04 of my laptop linux-gate.so.1 =&gt; (0xb776f000) libQtGui.so.4 =&gt; /usr/lib/i386-linux-gnu/libQtGui.so.4 (0xb6c8a000) libQtCore.so.4 =&gt; /usr/lib/i386-linux-gnu/libQtCore.so.4 (0xb69ad000) libpthread.so.0 =&gt; /lib/i386-linux-gnu/libpthread.so.0 (0xb6991000) libstdc++.so.6 =&gt; /usr/lib/i386-linux-gnu/libstdc++.so.6 (0xb68ac000) libm.so.6 =&gt; /lib/i386-linux-gnu/libm.so.6 (0xb6880000) libgcc_s.so.1 =&gt; /lib/i386-linux-gnu/libgcc_s.so.1 (0xb6862000) libc.so.6 =&gt; /lib/i386-linux-gnu/libc.so.6 (0xb66bd000) libfontconfig.so.1 =&gt; /usr/lib/i386-linux-gnu/libfontconfig.so.1 (0xb6688000) libaudio.so.2 =&gt; /usr/lib/i386-linux-gnu/libaudio.so.2 (0xb666f000) libglib-2.0.so.0 =&gt; /lib/i386-linux-gnu/libglib-2.0.so.0 (0xb6576000) libpng12.so.0 =&gt; /lib/i386-linux-gnu/libpng12.so.0 (0xb654c000) libz.so.1 =&gt; /lib/i386-linux-gnu/libz.so.1 (0xb6536000) libfreetype.so.6 =&gt; /usr/lib/i386-linux-gnu/libfreetype.so.6 (0xb649b000) libgobject-2.0.so.0 =&gt; /usr/lib/i386-linux-gnu/libgobject-2.0.so.0 (0xb644c000) libSM.so.6 =&gt; /usr/lib/i386-linux-gnu/libSM.so.6 (0xb6443000) libICE.so.6 =&gt; /usr/lib/i386-linux-gnu/libICE.so.6 (0xb6429000) libXi.so.6 =&gt; /usr/lib/i386-linux-gnu/libXi.so.6 (0xb6419000) libXrender.so.1 =&gt; /usr/lib/i386-linux-gnu/libXrender.so.1 (0xb640e000) libXext.so.6 =&gt; /usr/lib/i386-linux-gnu/libXext.so.6 (0xb63fc000) libX11.so.6 =&gt; /usr/lib/i386-linux-gnu/libX11.so.6 (0xb62c8000) libdl.so.2 =&gt; /lib/i386-linux-gnu/libdl.so.2 (0xb62c3000) librt.so.1 =&gt; /lib/i386-linux-gnu/librt.so.1 (0xb62ba000) /lib/ld-linux.so.2 (0xb7770000) libexpat.so.1 =&gt; /lib/i386-linux-gnu/libexpat.so.1 (0xb628f000) libXt.so.6 =&gt; /usr/lib/i386-linux-gnu/libXt.so.6 (0xb6233000) libXau.so.6 =&gt; /usr/lib/i386-linux-gnu/libXau.so.6 (0xb622f000) libpcre.so.3 =&gt; /lib/i386-linux-gnu/libpcre.so.3 (0xb61f3000) libffi.so.6 =&gt; /usr/lib/i386-linux-gnu/libffi.so.6 (0xb61ec000) libuuid.so.1 =&gt; /lib/i386-linux-gnu/libuuid.so.1 (0xb61e5000) libxcb.so.1 =&gt; /usr/lib/i386-linux-gnu/libxcb.so.1 (0xb61c4000) libXdmcp.so.6 =&gt; /usr/lib/i386-linux-gnu/libXdmcp.so.6 (0xb61bd000) </code></pre> <p>Then I am wondering how can they be different?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
