Dado que cuando he instalado Xubuntu 14.04.2 LTS en mi nueva computadora portátil, obtuve este comportamiento extraño que puede ver en estas pantallas (las barras negras se insertan para eliminar los datos privados, las pantallas representan lo que realmente veo en mi Desktop):

  • texto desaparece (perdón por la calidad de la mierda, pero fue tomada por mi cámara móvil )
  • Comportamiento de ventanas impares (en esta foto Las ventanas centrales se suponía que era un terminal: /)

Sucede cuando inicie sesión, sin ninguna acción específica de mi lado, y el problema se intensifica cuando uso el navegador o cuando se abren muchas ventanas al mismo tiempo.

Aquí están las especificaciones de mi computadora portátil:

  • Acer Aspire V15 (Código V3-572G-75CA)
  • Intel Core i7 5500U 2.4GHz
  • NVIDIA GEFORCE 840M 2GB VRAM
  • 8GB DDR3
  • 1000 GB HDD

Aquí está lo que obtengo de lspci:

Since when I have installed xubuntu 14.04.2 LTS on my new laptop I got this strange behavior that you can see in these screens (the black bars are inserted to remove private data, the screens otherwise represent what I actually see on my desktop):

  • Text disappear (sorry for the crappy quality, but it was taken by my mobile camera)
  • Odd windows behavior (In this pic the central windows was supposed to be a terminal :/)

It happens when I log in, without any specific action on my side, and the problem intensifies when I use the browser or when many windows are opened at the same time.

Here's my laptop's specifications:

  • Acer aspire V15 (code V3-572G-75CA)
  • intel core i7 5500U 2.4GHz
  • Nvidia GeForce 840M 2GB VRAM
  • 8GB DDR3
  • 1000 GB HDD

Here's what i get from lspci:
