We're deliberately exposing kernel problems early in the Natty cycle here in order that there's some hope of them being fixed in time for release. Reassigning to linux.
(I think you're on the wrong track regarding variable replacements. $linux_gfx_mode is almost certainly expanded to "keep". If you want to override this in order to get your system working more conveniently, then edit /etc/default/grub and add GRUB_GFXPAYLOAD_LINUX=text, then run 'sudo update-grub' - but this will disable smooth boot visuals we're working on so we don't want to make this the default if we can get the kernel side fixed instead.) ** Package changed: grub2 (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/685611 Title: [Natty] Booting fails because of GRUB setting "set gfxpayload=$linux_gfx_mode" -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
