laptop-detect does not recognise Sony Vaio laptop

[Wizzu]

Binary package hint: laptop-detect

I've just upgraded from Intrepid to Jaunty (Ubuntu 9.04). A few things broke, one of them is that it seems Ubuntu does not think it's running on a laptop anymore.

wizzu@spirit:~$ laptop-detect -v
We're not on a laptop (no relevant hint found)

The installed laptop-detect package version is 0.13.7ubuntu1

Laptop information:
bios-version:R0021N3
system-manufacturer:Sony Corporation
system-product-name:VGN-TX3XP_B
system-version:J001QD5V

Other things no longer working:
1) getting a message of "CPU frequence scaling unsupported" (I have the CPU Frequency Scaling Monitor applet installed) when I login to X
2) the Battery Charge Monitor applet no longer showing the battery charge level (says "0:00", and "running on battery" even though I have power connected)
3) fan running all the time
4) fn-keys for brightness controll no longer working
5) touchpad no longer working - I have filed a separate bug 368954 about that

I am not sure what is the proper package to report a bug against about these myriad of symptoms, all of which seem to derive more or less from the same source -- Ubuntu not detecting being on a laptop. I'm not sure if laptop-detect is authoritative on that.

On Intrepid, and releases before that (at least Feisty and Hardy), there were no problems.

You can find dmesg etc. files attached to bug 368954 but I can re-attach also here on request.

After more poking around, I've found the problem:

I had acpi=off in the kernel command line (I had added this previously in order to try to get around some shutdown issues, but it had never affected laptop detection before now).

With acpi=on (or rather, no acpi definition), lapop-detect -v reports "We're a laptop (ACPI batteries found)"

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner.
