X-ORG error Messages

[spandey]

I am using Mint9 Gnome. My pc is Intel c2duo, 3 GB DDR2, 250 GB SATA, Intel DG31PR mother board, Intel G31 express graphics.

I am a linux beginner so please bear with me. I am trying to figure out these X-ORG error messages:

Generally warnings are not worth worrying about. If you ever start compiling programs from source, you'll see hundreds sometimes. Errors (which would be marked with EE in Xorg.0.log) are a different story of course.

The ACPI warning probably just means your computer doesn't have ACPI, or that it's switched off in the BIOS.
