Maybe it should not be loaded with this laptop version, or it has a bug in it. Bluetooth is autodetected by acer-wmi, so aced you do not have emi bluetooth module installed in your laptop, this file won’t exist please be aware that it is quite common for Acer not to fit bluetooth to their laptops – so just because you have a bluetooth button on the laptop, doesn’t mean that bluetooth is installed.

Brightness must be controlled by acpi video driver [ Ubuntu hangs, and reacts normally after 10 seconds. As such, I do warn that this could break your hardware – this is extremely unlikely of course, but please bear this in eextras.

Bluetooth and wifi work, also the volume keys. Forgot to mention that I indeed also had tested it with v3.

Despite this, what could be expected if it’s not a BIOS bug, is a quirk of some sort that minimizes or eliminates the 10 second delay. It continues after that. I briefly scanned acer-wmi and didn’t see anything patently obvious code extrae as to why this would occur with a non-OEM provided WiFi chip although I’m not terribly familiar with it.

Peter de Kraker, thank you for performing the requested test and the follow up information. Once testing of the upstream kernel is complete, please mark this bug as “Confirmed”. Installed on 0 days ago InstallationMedia: I will add a dmesg from a boot with acer-wmi enabled.

Excerpt to see the timejump: For the adventurously minded – if you want to buy an internal bluetooth module off the internet that is compatible with your laptop and fit it, then it will work just fine with acer-wmi. Solid light, blinks off when transmitting Wireless radio control is unconditionally enabled – all Acer laptops that support acer-wmi come with built-in wireless.

When I remove the wireless card or reinstall the ader original one modprobing acer-wmi finishes immediately and succesfully with no hangs. Peter de Kraker, thank you for reporting this and helping make Ubuntu better. Penalver penalvch on Changed in linux Ubuntu: So, clearly something is wrong with acer-wmi. The screen laptp and the fans start spinning very hard. If this bug is fixed in the mainline kernel, please add the following tag ‘kernel- fixed-upstream’. Please test the latest v3.


Intel Corporation WiFi Link [ See full activity log. I don’t know now if this is still a valid bug, since maybe the card is not fully supported by the laptop while it works ok besides this issue.


Thank you for your understanding. To post a comment you must log in. It is not responsible for the wireless LED – once extraw radio is enabled, this is down to the wireless driver for your card. The backlight is exposed through the backlight subsystem, and can be found in:
