http://ubuntuforums.org – Hi, I recently bought Lenovo Y480 and have installed Ubuntu 12.04 on it. However, it is not detecting ethernet connection. It is getting detected on Windows though on the same laptop. I tried to follow these steps http://www.zyxware.com/articles/2680...n-ubuntu-12-04 But,it shows this error at the end: sushant@sushant-Lenovo-IdeaPad-Y480:~/Downloads/compat-wireless-2012-05-10-p$ make install FATAL: Could not open /lib/modules/3.2.0-29-generic/modules.dep.temp for writing: Permission denied make: *** [uninstall] Error 1 sushant@sushant-Lenovo-IdeaPad-Y480:~/Downloads/compat-wireless-2012-05-1 (Hardware)
