Problems with logging into Ubuntu Linux overnight
When coming in the morning and waking up my monitor I see: “Fatal server error. Failed to submit batchbuffer”. Requires to reboot computer!
Appears to be a known problem in Linux community. Not resolved yet for Ubuntu distro (10.04 LTS).
To my mind, it happens when display/video card goes to sleep (30min set in Power Management application) and video card is still getting data from the screensaver.
Not any screensaver causes the problem, but only OpenGLText so far. I think, this particular saver uses hardware graphic accelerator while other OpenGL images do not.
So, to fix this either do not use OpenGLText screensaver neither use any other that may work with h/w accelerator or
never put display asleep in the Power Management.
