I am seeing the error message 'Xlib: extension "GLX" missing on display'.

GLX extension is required for displaying 3D objects. GLX extension is included in Xmanager Enterprise.
[For Xmanager 1.3 Users]
When you use a OpenGL based application, the error message 'Xlib: extension "GLX" missing on display' is shown because Xmanager 1.3 does not support OpenGL.
If you do not have a problem in the use of your desired application, you can simply ignore the error message. Otherwise, please follow the instruction below to turn off OpenGL functions in your application.
  • I-DEAS (CAD)
    Run "-dX3D" option

  • xmakemol
    Debian Linux: Use xmakemol package instead of xmakemol-gl package supporting OpenGL
    Redhat Linux: Turn off all configure options related to OpenGL during installation as follows
    ./configure --with-mesa=no --with-opengl=no --with-glu=no --with-glw=no

Colors are not displayed correctly when I use 256-color CAD applications.

Some old X applications using 256-color visual cannot display colors correctly in the True color video device. Mostly, CAD applications such as Cadence, Mentor and CATIA have this problem.

Default Visual: PseudoColor
Backing Store: When Mapped
These options will enable 256-color emulation feature in Xmanager.
