Re: Y450 linux?

Thanks for the reply. Yes, adding that to the boot options doesn't seem to help. 

 

I am pretty sure the hardware is bad for the sound. I've never heard a sound at the splash screen. I really wish all these hardware issues were taken care of before Lenovo shipped my computer out. 

 

I haven't tried using battery only on 9.10 but I got around 3 hours with 9.04. I will check to see what I get in Win 7 next time I have a long class. These issues alone are not enough for me to switch back to Windows 7. With compiz, emerald, and awn dock it looks so much better and I can customize it to how I want it. 

 

I'm going to try a few more things for the brightness to see if I can get it to be more user friendly to change.

This is the only way I have been able to get the brightness to change. 

 

sudo setpci -s 00:02.0 F4.B="20" The 20 means it's at 20% brightness. It goes from 1-FF, FF being 100% brightness. Also, make sure you remove the quotes. This is with 64-bit 9.10.

 

gnome.do > awn. I also recommend screenlets.

kwardle,

 

I notice you're running 9.10 also, I'm playing with it on my Y450, and while 99% of stuff works great, I can't for the life of me get the internal mic to work, or brightness, any clues on what you've done for those? I tried playing with mic options in the alsamixer, but all I get is static if I turn on the front mic there (and all that sound preferences seems to list is a single input option?)

 

The sudo command does change my brightness, but it's going to be a pig to have to use that all the time, anyone figure other options? Waiting for my windows 7 disks to arrive to play with that, while I prefer ubuntu for MOST things, there are things I just have to use windows for.

Hi Arla,

 

I used dsides command to setup a script which automates everything. It basically uses keyboard shortcuts to trigger stuff (as non-root) that executes dsides command as root by monitoring a file. It makes the brightness keys fully functional. I've posted the script and a more detailed explanation on my site http://elektropionir.net . It's working great for me, let me know if you have any problems. I'm using it on an IdeaPad Y450 running Karmic Koala but I think it can probably be easily modified to run on other laptops as long as dsides command works on them.

dsides, I got everything to work now, so you might want to give it a try although it does seem like you might have a hardware problem (have you tried just playing a file in rythmbox?). To get the mic to work I just needed to install linux-backports-modules-alsa-2.6.31-14-generic. That was it, everything just worked after that. My alsamixer options changed (I lost the option for front/internal mic). For brightness (which will probably improve battery life since the screen is super bright by default) see my post above. I added the installation of linux-backports-modules-alsa-2.6.31-14-generic to the script on my site, so if you run the script you should have a fully functional Y450 after reboot (brightness + mic working).

Re: Y450 linux?

I cannot get this to work with 9.10 64 bit.  The only error I have seen is

update-rc.d: warning: /etc/init.d/brightness_updater missing LSB information
update-rc.d: see <http://wiki.debian.org/LSBInitScripts>

 

The original command posted by dsides works, but the script to make the keys work does not.  My screen does however dim when I try to run the script.   Any help would be appreciated

jaba, did you reboot? That warning should not be a problem (I just didn't put some info in the script - I get the same warning on my machine but the init script works fine). What happens if you just execute

/etc/init.d/brightness_updater

from the command line as root? Can you adjust the britghtness then?

 

After reboot, execute

ps -aux | grep brightness

do you see the dnotify process?

I rebooted, tried running /etc/init.d/brightness_updater, nothing happens when I use the brightness keys.  ps -aux | grep brightness displays the following results for brightness...

$ ps -augx | grep brightness
Warning: bad ps syntax, perhaps a bogus '-'? See http://procps.sf.net/faq.html
root 1026 0.0 0.0 3916 264 ? Ss 21:31 0:00 dnotify -b -a /var/brightness/ -e update_brightness
jabs 1982 0.0 0.0 7340 964 pts/0 S+ 21:32 0:00 grep --color=auto brightnes

 Any ideas?  I'm pretty sure I did everything right from the beginning.  Downloaded your script, ran it at the terminal with sudo sh sudo sh setup_brightness_controls.sh.  Everything appeared to work fine, I rebooted and the keys did not work.

Re: Y450 linux?

OK this is your problem:

 

sudo sh sudo sh setup_brightness_controls.sh

 

You should run this as normal user (the one who you are logging in when you want to change the brighness):

 

sh setup_brightness_controls.sh

 

I said this in the instructions on my site but it might not be comletely clear (I updated the post to make this clear). Since you run the script as root the keyboard shortucts were setup for the root user instead of the normal user.After you run the script as normal user it will setup the keyboard shortcuts and you should be good to go.

 

P.S. The script will ask you for the sudo password since it needs to do some things using sudo.
