Comment 55 for bug 318325

I noticed upstream http://bugs.freedesktop.org/show_bug.cgi?id=20478 asked whether it's a problem with a newer version of the driver or with KMS so I am trying to learn how to figure this out. I believe the xorg-edgers PPA tested the newer version but until now I wasn't aware of KMS at all.

I haven't experienced KMS issuex yet on my other hardware. SO I read http://www.netsplit.com/2010/03/30/all-about-kernel-mode-setting/ for an overview and https://wiki.ubuntu.com/X/KernelModeSetting for how to try different modes.

I hope nobody minds me making my notes in this bug. If anyone can suggest the most efficient way to test this please let me know.

P.S.: The Acer 5100 original install was a 10.04 Lucid UNE image, then upgraded online to 10.10 Maverick UNE. I believe the laptop's boot volume may be encrypted (it displays a message on boot), though I didn't intentionally choose the encrypted option. The ubuntu wiki mentions kernel mode changes need to get into initramfs for encrypted volumes, so I might reinstall Maverick from scratch to avoid that complication. Just in case.
