Hi Christopher,

I'm afraid not. This desktop is my main workstation with loads of SDKs
and tools installed. It is a work PC so I cannot switch to a live image
for more than few minutes. The problem is that this takes like 1 or 2
weeks to appear again. Any other suggestion?

Thanks,
Roberto

Title:
  Graphics performance degrades with time in 14.04

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  After several days using the system the graphics performance degrades.
  I cannot find any information in syslog or dmesg. It takes an awful
  amount of time to open a new window, and during that time the mouse is
  trapped into one of the monitors (cannot move to the other one). Also
  I've noticed that the Unity notification bar freezes and I cannot
  access any of the icons there, and the clock is just frozen.

  HDD, memory and CPU load seem normal. The only solution I've found is
  to reboot.

  Thanks in advance.
