Bluetooth on IBM Thinkpad automatically gets enabled when Ubuntu is restarted

[Deepak Singla]

I am using IBM Thinkpad R52 and have upgraded from Ubuntu 8.04 to Ubuntu 8.10 beta. After the first boot I realized that the bluetooth on my laptop has got activated. The bluetooth light on the laptop was lit and a bluetooth icon was coming on the taskbar as well. however I could easily deactivate it with Fn+F5 keys. When I restarted the bluetooth was back to its active state. I repeated the process and the same happened.

Ideally Ubuntu should remember the last state of bluetooth device and keep the same when it is restarted.

I too can confirm this behaiviur on ThinkPad R52 and Kubuntu 8.10 Beta.

But in Kubuntu Bluetooth frontend don't work, and according to another reportet bug this isn't going to happen for 8.10. Therfore activating Bluetooth automaticaly do not seem right to me.

IBM Thinkpad T61 exhibiting the same behavior after an upgrade to the 8.10 release. All same symptoms as original report. Enabled after each reboot. Hotkey Fn+F5 works fine to disable bluetooth, but keep wireless up. Did not have this problem in 8.04.

Same for me on a Thinkpad R61.

I haven't quite figured out the pattern, but I've noticed -usually- if I boot into windows, bluetooth will be turned off automatically (or I turn it off manually). And then rebooting back into ubuntu it stays off.

For a while this was working consistently, but lately I've been having some anomalies with that, so can't say its a true workaround. As far as I can tell, there's no way to control bluetooth from the bios, so you're dependent on the OS or the hardware toggle (which also disables wifi) to prevent bluetooth from coming on at startup.

Thinkpad R52, Ubuntu 8.10 upgraded from 8.04. Dual-boot with Windows XP.
Upon booting into Ubuntu Bluetooth is always on indiscriminate of what the state was last time, or what the state was in Windows.
Such behavior was not observed in 6.06, 6.10, 7.04, 8.04 (I skipped 7.10 upgrade).

I have the same problem on my Acer Aspire 5520G. But for me it appeared only with Jaunty (I use all from alpha version). Now I have RC installed and every time on boot bluetooth turns on. I don't need it every time, so it's too boring to turn it off every boot.

With 8.10 and previous versions I didn't have such problem.

PS May be I have to make new bug report?

I have the same problem on a Thinkpad R60

[Christophe (christophe-wk3)]

This problem still exists in Lucid

[Lasse Riis (lasse-riis)]

Confirmed still a problem on Lucid and TP X201i.

Even disabling bluetooth on the thinkpad_acpi module via modprobe.conf* fails. Apparently because it is requested at boot time when the radio is "blocked". See bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/556404).

*) should be similar to/same as echo'ing disable into /proc/acpi/imb/bluetooth or whatever

Possibly these two bugs should be joined...
