How do I get wireless and video working on a Sony Vaio vpc-z21x9r
- by Alex
OS: Ubuntu 11.10
Kernel: 2.6.37.6
Laptop: sony vaio vpc-z21x9r
The problem: I can't change level of screen backlight; also can't enable wi-fi.
While using 3.0 kernel everything is ok, but the laptop discharges too quickly.
Results for lspci
02:00.0 Network controller: Intel Corporation Centrino Wireless-N + WiMAX 6150 (rev 5f)
VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
there is no wlan0 in ifconfig -a too.
I've fount that kernel should already have drivers for this graphics controller, but when i load up in restore mode, it writes "fall" while trying to load up some video drivers.
To change the level of backlight i've alrady tried:
xbacklight -set XX
,
smartdimmer -s XX
and got this
init_ nvclock() failed!
also sudo setpci -s 00:02.0 F4.B=XX
with no results.
As for wi-fi, i've found driver but i don't understand how to install it. Here it is
How can I fix these problems?
Thank you for your help and time!
Also tried to fix problems with backlight writing GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset acpi_backlight=vendor
Still no results.
Is there any sense in recompiling kernel, I mean 2.6.37.6. Can it make any improvements in the situation?
