Never experienced flickering since updating to Natty (2 weeks ago), but the max resolution 1024x768 but the Acer AL1702w monitor can do 1440x900. Video Card is a built-in Intel G915 on a Core2Duo Processor. Had no problems with Ubuntu 10.10. dmesg spits a lot of EDID invalid checksum kind of errors.
