elektropionir,

Thanks for all the help, I've not had much luck, looking at your alsamixer screens though they are fairly different, I have both mic and front mic, and mic boost, and front mic boost on mine, so something must be different.

Going to reinstall Karmic since I've been upgrading for ages and have messed with a lot of packages trying to get my mic to work, will probably try to get everything BUT the mic working to start with, backup the system, and then start really messing with packages, hopefully it will get somewhere.

[#2]

No problem. About the mic, yes if you have the front and internal mic it won't work. I am pretty sure it's the backbporst package that fixed it which also gets installed by the brightness script:

http://packages.ubuntu.com/karmic/linux-backports-modules-alsa-2.6.31-14-generic

it provides the latest snapshot of alsa so basically you get the latest drivers. I updated the script to install the metapackage linux-backports-modules-alsa-karmic-generic as suggested in that link above so get that version when you do your fresh install, I bet the mic works.

Your a star elektropionir,

While I haven't bothered with the brightness patch (quite frankly, I rarely change my brightness, quite happy with full brightness, and don't really use it away from a power-source very often) I'm just glad that the Mic now works! Now I can start to play with Ekiga instead of Skype

[#4]

Thanks Arla, I'm just stubborn - this laptop is a brick to me if I can't run linux with skype on it and be able to change the brightness so I had to fix it. We should really thank the alsa developers that actually wrote the driver though.

Guys, there was a bug in that latest script. I fixed it and included a cleanup script in case you want to uninstall the brightness scripts or just to cleanup before this bugfixed install. In case you tried to use that broken script download the new version:

Sorry about the bug.

Thanks for the update elektropionir,

As a side note, did you notice that .15 is out for the Alsa backport? Seems to work fine for me (or at least hasn't stopped my mic working).

I've tried the script but got mixed results. I could not get the arrow keys to work so I decided to bind 1 - 10 on the keypad with various brightness settings. I used "gksudo set_brightness 10" and binded it to Ctrl+1, normally I would only have to enter the sudo password one time at start up or whenever and would not have to enter it again for my session. I am not sure if  the brightness is going all the way up though. I have to boot into windows to check. For the most part it seems to work.

dsides, did you try the latest version of the script:

Run the cleanup script then the setup script and it should work without you having to do anything on boot.

I finally figured out how to get two finger scrolling working on the Y450.

The answer can be found here...

I just got my Y450 this week and I'm currently installing Arch Linux on it.

So far, I had the same problems as you guys mentioned.

I have to thank you all for this thread =]

and I have a few questions:

dsides: how did you manage to find that command to change the brightness?

does any of you managed to get the slidebar or the two first buttons working?

I tried running 'showkey'  and none of them return anything. I imagine one should have to send a signal to the controller to turn these buttons on. I'll try to get that working.
