Desde la actualización a Ubuntu 18.04 (desde 17.10) comencé a experimentar grandes problemas de rendimiento con la reproducción de video, tanto usando VLC como el navegador (Youtube).
El problema se hace más evidente cuanto mayor es la calidad del video (comienza a 480p, 1080p es completamente imposible de ver). El video es entrecortado por decir lo menos.
No tuve tal problema usando Ubuntu 17.10.
Me pregunto si hay alguien que también tuvo el mismo problema y encontró una causa potencial y tal vez una solución.

ACTUALIZAR:
Parece que es un problema general con la aceleración / representación de hardware no habilitada / reconocida / funcionando.
Las cosas que he probado hasta ahora:
Reiniciar.
Agregue el archivo de configuración xorg.conf con:
Section "Device" Identifier "Device0" Driver "radeon" EndSectionReinstalación
xserver-xorg-video-radeon.
Ninguna de estas cosas tuvo ningún efecto desafortunadamente.

¿Por qué ves videos en una máquina virtual? El rendimiento no será excelente sin importar lo que esté instalado.

No entiendo del todo. ¿De dónde asumes que uso VM?

La salida de glxinfo está llena de la cadena "VMware, Inc".

Muy bien, no me di cuenta de eso. Para ser claros, estoy ejecutando Ubuntu directamente en HW, no dentro de la VM. ¿Podría ser el problema la configuración de OpenGL de algún tipo?
