I currently have a problem namely the Fn F5 on my X61s. This laptop has a physical radio switch but is also controlled with the mentioned funtion key. The problem is yesterday after rebooting my debian sqeeze system the wi-fi switched off, something that occaisonally happened when i first had the laptop with vista a few years ago (of course this wasn't a problem as windows had full thinkpad hot key support). So, i am now unable to access the internet from my X61s (am writing this on a friends laptop). Would anyone know of any packages or workarounds that i can apply to get this function back as i no longer own a windows cd and do not want or need a dual boot system especially for the sole purpose of being able to use 1 function key.
Any suggestions would be deeply appreciated, thank you
there does seem to be something there. The problem is that i can't see an entry for the wifi. On the X61s fnF5 rotates through the functions, eg bluetooth and wifi on, wifi on and bluetooth off, wifi off and bluetooth on, wifi off and bluetooth off.
I do remember once, about 2 months ago (i am very new to linux) that i was trying some distributions out, one of them was mint (i decided for several reasons that it wasn't what i was looking for) but i do remember full functionality of the function keys especially fnF5. I am going to re-install it (i left a spare 10Gb partion) alongside and see if i can see what similar investigations shows me there.
This indicates a newer version i am tempted to think that this may be an answer as i can't see any other differences but this is not the version of mint i used a couple of months ago. Now using 11 not 10 as i did then. I am of course guessing but i suspect that that version also used the one that debian is.
So, what is the difference? I can't see any entries that differ from debian squeeze but this does have full hotkey functionality. Of course i am more than open to the idea that i am barking up the wrong tree when tackling this problem.
/proc/config.gz only exists if it is enabled in the kernel, otherwise you would have to find the kernel config somewhere else.
From what I see, the driver exists and is being used in both cases, the only difference being like you said the version of the drivers. In that case, I would try upgrading the kernel in Debian, if possible.
hmm.. i worried that that was going to be the situation. I am doing this for my own benefit now. On Mint:
sudo grep -r THINKPAD /boot | cat > thinkpad.txt
bash-4.1$ cat thinkpad.txt
/boot/config-2.6.38-8-generic:# CONFIG_THINKPAD_ACPI_DEBUG is not set
/boot/config-2.6.38-8-generic:# CONFIG_THINKPAD_ACPI_UNSAFE_LEDS is not set
/boot/config-2.6.32-5-amd64:# CONFIG_THINKPAD_ACPI_DEBUGFACILITIES is not set
/boot/config-2.6.32-5-amd64:# CONFIG_THINKPAD_ACPI_DEBUG is not set
/boot/config-2.6.32-5-amd64:# CONFIG_THINKPAD_ACPI_UNSAFE_LEDS is not set
If it is compiled properly, it shouldn't cause instability. http://www.debianhelp.co.uk/kernel2.6.htm
You could also try installing the kernel from unstable debian or mint, if you don't want to compile it yourself. However, that may not be stable.
I have a shiny new kernel and all is functioning well, except that fnF5, i think i am just going to leave it, after i installed mint to look at what they do i managed to switch it on with that. So i will just have a live CD at hand. The only problem now is the:
startpar: services returned failure: rc.local ... failed!
Which is a slight pain as i have my fbset configuration residing in there
but it was fun to do. Thanks for the link i think that site will prove helpful in the future
