I had installed OpenGL and freeglut in Ubuntu 10.04 and it worked fine in 10.04 and 10.10. But after I upgraded to 11.04, the applications I've developed using OpenGL is not running properly. They're compiling without errors, but when I try to execute them, I get there errors:
For GLUT:
Xlib: extension "GLX" missing on display ":0.0".
freeglut (./a.out): OpenGL GLX extension not supported by display ':0.0'
For just OpenGL:
Xlib: extension "GLX" missing on display ":0.0".
main: X server has no OpenGL GLX extension
A few things I tried:
$glxgears Xlib: extension "GLX" missing on display ":0.0". Error: couldn't get an RGB, Double-buffered visual $glxinfo name of display: :0.0 Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Error: couldn't find RGB GLX visual or fbconfig Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0".
Edit: It is unlikely that this is because I don't have the graphics drivers as all I have is on board graphics.
This is my system graphics information from sysinfo
$sysinfo GRAPHIC CARD VGA controller Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) (prog-if 00 [VGA controller]) Subsystem: Toshiba America Info Systems Device ff50
Edit 2: And it seems I have a driver installed for that.
