I have been experiencing this problem since installing 10.04 Lucid LTS on a Dell Inspiron 530. If I don't use the machine for a period of time, the monitor goes into power save mode and then I get a window telling me that Ubuntu is running in low-resolution graphics mode. If I look at the X log file, I see the "Failed to submit batchbuffer: input/output error" message. It is very irritating, because if I choose the option to continue to use low-resolution, it sends me to the login prompt and the state of all the work I was doing is gone. // welshgeek
