Ubuntu 32-bit 11.04 beta 2 with latest updates.

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.

[code]
dmesg | grep -i acer -B 2 -A 2

Changed xorg.conf several times following several tweaks - but no good.
