Okay, two questions.
1. What's the deal with my refresh rate in Linux. In the Screen Resolution window selecting 1280x960 the only choice I have is 51 Hz. In XP I could run 72 Hz at that resolution. It also lists my monitor as unknown. The NVIDIA X Server Settings tab recognizes my monitor, but the only two choices for 1280x960 are Auto and 60 Hz. How do I get my monitor to display 72 Hz in Linux?
2. When I boot up Ubuntu it says to enable IOMMU in BIOS. I looked and couldn't seem to find anything to do with IOMMU in my BIOS. What is IOMMU anyway? Is it important?
