Happened with mine after disconnecting AC (pm-utils switch hd with hdparm to -B 128, which parks heads after approx. 5 seconds. Because some apps write to disk regularly (e.g. firefox) disk was de-parked with next disk access. Not good for disk. It's that slight clicking sound on battery.
True, but for my uses 60fps is more than enough.
Just today I actually had a problem. initrd was failing with "no init" if BIOS was set to "switchable", but with "discrete" (== Radeon) it booted just fine and on glxgears I get approx. 550fps with 36% cpu usage.
edit 02.10.10 - It works again with both graphics adapters enabled and switchable and even brightness adjustement works on the Intel Graphics. Changes: grub commandline changed from acpi_osi="Linux" to acpi_osi=Linux (without the quotes).
With 1st time Radeon used for Ubuntu I can confirm this now. Brightness can then obviously not be adjusted using Intel integrated graphics.
I have updated to 1.17 even before really getting to a useful state . I toggled all wireless possibilities through - BT shows up extremely short as usb-device in syslog, but cannot be handled properly and gets deleted right afterwards:

Guess I should investigate on that further.
True
