2:2.4.1-1 broke ACPI on MacBook 2nd gen

[damian]

Binary package hint: xserver-xorg-video-intel

after the latest update of this package installed automatically, the battery monitory applet in Gnome stopped working properly: it reports whether or not i'm plugged into AC but power %age is always 0.

the system still automatically suspends when power gets critically low, but i can no longer see the current percentage. /proc/acpi shows only BAT0, with this info:

when i plug in AC, 'charging state' changes to 'charging'.

I find it strange that an update to the video driver should cause this, but there have been some other problems with the upgrade to 2:2.4.1-1ubuntu10.3. Other people have verified that it is this package by downgrading to the previous version (which I think is 1ubuntu10, since 10.1 and 10.2 apparently never made it out of the -proposed respository). Could you try the same? Also, does it work well if you don't _use_ the driver, e.g. by adding the line
Driver "vesa"
to the Device section of your xorg.conf?

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

[I agree this doesn't sound like an X bug... would need added justification for that.]
