           Summary: GL Applet errors with misleading text
           Product: plasma
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org
        ReportedBy: rjpbitanga yahoo com


Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2) 
OS:                Linux

OpenGL is not correctly detected for the Test GL Applet 2 and blue marble applets.

The following console output is produced:
QGLPixelBuffer: Unable to find a context/format match - giving up.

The above code is caused by code in glapplet.cpp. Test GL Applet 2 fails in paintInterface(). bluemarble fails in BlueMarble::initializeGL(). The OpenGL version string is empty in initGL() in kwinglutils.cpp in the bluemarble source directory. bluemarble should have detected that OpenGL could not be initialized instead of using the "shader not supported" message. In any case, something is wrong in glapplet.cpp, at least on my machine.

My system uses the proprietary fglrx driver from ATI. glxinfo reports that direct rendering is in use and shaders are supported (I checked everything needed in kwinglutils.cpp). KDE was installed following the instructions in techbase (as a separate user).

Sample GL applet works and other OpenGL features work (for KWin).
