Bueno mi problema es que desde que actualicé mi Kubuntu KK a LL ya no puedo utilizar GL (OpenGL) como lo venía haciendo... Debe de ser algo que pasó durante la instalación porque el Kubuntu HH que tengo en otra partición funciona de lo más bien.

Vi que había un tema semejante en el foro, pero no ofrecía ninguna solución sino solo instalar sysinfo, lo cual no lo requiero porque, bueno, en KDE hay otras opciones para ver eso o simplemente se usan comandos en konsole, no?

XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"

Ese error al final solo ocurre si cierro a propósito la ventana con los engranajes giratorios.

Lo único que se me ocurre a estas alturas, después de ver que los drivers están instalados en sus respectivas carpetas, que el problema o es con la versión del driver o controlador que incluyeron en LL o algo le pasó a la actualización de mi sistema de KK a LL.

Espero que me puedan brindar alguna ayuda al respecto.
