Technical FAQ

If connecting remotely to a Linux machine using XRDP, the 3D viewers in NORSAR Software Suite can get a transparent background. To fix this, edit the XRDP settings:

Edit the file: /etc/xrdp/xrdp.ini

Change max_bpp=32 to max_bpp=24

Uncomment the line: serverbpp=24

Restart the XRDP server.

A project located directly on the root folder of a Windows disk can cause various problems. Moving it to a sub folder solves the issues.

This can cause problems:
N:\MyProject

This works:
N:\projects\MyProject

A project can safely be moved to a sub folder after it has been created.

This can happen when running NORSAR-3D or NORSAR-3D legacy tools using a remote X server solution, like FastX.

It can usually be solved by either enabling indirect rendering (for FastX, see OpenGL Support for legacy apps: https://www.starnet.com/xwin32kb/opengl-support-for-legacy-apps/)

or

setting the DISPLAY variable to the machine running the X server:

If X server is running on a Windows PC named WinPC, set environment variable DISPLAY=WinPC:0

Error message when trying to start NORSAR Software Suite on Linux: "Cannot mix incompatible Qt library (version 0x40805) with this library (version 0x40807)"

Unsetting or setting blank QT_PLUGIN_PATH environment variable should fix the problem.

If the self extracing NORSAR Software Suite installer hangs on Linux (never finishes unpacking), you can extract the tar.gz file for manual extraction. To get a tar.gz file type:

tail -n +165 NORSAR_Software_Suite_<version>_Installer.sh > NORSAR_Software_Suite_Installer.tar.gz

Then extract the tar.gz file with:

tar zxvf NORSAR_Software_Suite_Installer.tar.gz

Note: This will extract the files in the current directory.

If you experience a blank user interface with no text in some modules, please follow these instructions.

If the user interface is blank again after a restart (after following the instructions above), please update to the latest version of the software.

If you experience too small or too big fonts in some NORSAR-2D or NORSAR-3D modules, you can use a tool called qtconfig-qt4 to adjust the font sizes. qtconfig-qt4 is usually included with most Linux distributions. If you don't have this tool it can be installed using the provided package manager in your Linux distribution.

• If you get font warning messages like:
  
  "Warning: Cannot convert string "-adobe-courier-bold-r-normal--18-180-75-75-m-*-iso8859-1" to type FontStruct"
  
  the font pack called "A set of 75dpi ISO-8859-1 fonts for X" or "xfonts-75dpi" must be installed on your system.
   
• If you get messages like:
  
  XngOpenX: Could not find font 8x13
  XngOpenX: Could not find font 9x15
  
  the font pack called "ucs-miscfixed-fonts.noarch" must be installed on your system.

The font packs can vary from Linux distribution to Linux distribution. If unsure or the above doesn't solve the problems, install all available font packs: yum install *fonts*

If you get messages about missing libraries when starting NORSAR software (for example missing libraries libXp.so.6 or libGLU.so.1 etc.), you will have to install these libraries. On RedHat or CentOS, they can be installed by using yum:

As root user, type:

yum search libXp

Only type in the name of the library, not the extensions (.so.6 in this example. Also try without lib if nothing is found). This will show a list of packages, for example:

libXp.i686 : X.Org X11 libXp runtime library
libXp.x86_64 : X.Org X11 libXp runtime library
libXp-devel.i686 : X.Org X11 libXp development package
libXp-devel.x86_64 : X.Org X11 libXp development package
libXpm.i686 : X.Org X11 libXpm runtime library
libXpm.x86_64 : X.Org X11 libXpm runtime library
libXpm-devel.i686 : X.Org X11 libXpm development package
libXpm-devel.x86_64 : X.Org X11 libXpm development package

We want to install the X.Org X11 libXp runtime library. To install the 32-bit version of the library, type:

yum install libXp.i686

To install the 64-bit version, type:

yum install libXp.x86_64

Make sure that you install the correct 32 or 64-bit version, or if you are unsure, install both.

You can also use the yum provides command, but this will sometimes only list the 32 or 64-bit version of a library and also different versions numbers, so yum search is safer to use. Type:

yum provides libXp.so.6

Look for something like this:

libXp-1.0.0-15.1.el6.i686 : X.Org X11 libXp runtime library

Type:

yum install libXp-1.0.0-15.1.el6.i686

To fix this, log in as root and do the following:

chmod 0666 /dev/nvidia*
chown root /dev/nvidia*
