I can confirm this bug with the same machine: non-native resolution and flickering, after installing the beta2 this morning.
A workaround for installation is to resort to the alternate-CD. Rebooting after finishing installion ends in black screen, but changing then into a console w/ CTL+ALT+F1 and restarting lightdm (sudo service lightdm restart) makes login screen accessible. Choosing there 2D- Desktop opens the Unity desktop, without "artifacts", but with the wrong resolution and the slight flickering already reported by @Svante. gnome- settings-daemon does not provide other resolutions. By the way, adding "console=tty1" to grub default options does not resolve the problem, neither updating all the packages at their last version. I keep investigating just in case, though kernel freeze is already done. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-psb in Ubuntu. https://bugs.launchpad.net/bugs/972294 Title: Precise GMA500 screen resolution and flicker To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-psb/+bug/972294/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
