Re: Y450 linux?

2009-11-24, 2:51 AM

When you say two first buttons? Which are you talking?

 

I've not bothered trying to get the slide-bar working, although it would be nice if it did, waiting for my Windows 7 disks where it will work, although I'm really not booting into windows much at all these days.

I mean the dolby button and the one on the left of it.

 

I installed windows7and I plan on trying to reverse engeneer the drivers when I have the time (which will probably be on dec or jan).

 

Also, I installed cpufreq to control the cpu frequency when I am on batteries, and it can go as low as 800Mhz. Which makes the batteries last longer.I

Re: Y450 linux?

I just received my Y450 and I am having the same problem.  I think I can get it to work by modifying the scripts provided by elektropionir based on the setpci commands provided by dsides.  I just need to know how the register "F4.B" was determined.  Thanks in advance.

 

Details:

 

The problem I am having is that

 

sudo setpci -s 00:02.0 F4.B=20

 will not work for me because the the device address on my computer is 

 

01:00.0 VGA compatible controller: nVidia Corporation Device 0a34 (rev a2)

 Changing the command to

 

sudo setpci -s 01:00.0 F4.B=20

 does nothing.    The result of 

 

sudo lspci -vvvxxx -s 01:00.0

 is

Here is some information about the thinkpad acpi, but I do not know about applicability to ideapads. In any case, I can't configure backlight.

I've found a trick! But it is not a solution actually.

You can change the brightness in tty.

1) Press "Ctrl + Alt + F1"

2) Wait until you see a login invitation

3) Change the brightness!

4) Press "Ctrl + Alt + F7" to go back to XServer.

5) PROFIT!!

lennyC2,

 

Do you mean to say that Nvidia's  drivers freezes your system?

I think you can try using the alternative of nvidia for your distribution.
