Ubuntu 8.10 fixes my Lenovo Y410 problems
I installed Ubuntu 8.04 Hardy Heron to my Lenovo Y410 laptop a few weeks ago. There are two main problems that bother me. First, the sound is not working. After searching around the web, I found a solution, refering to suspend with FN-F1. FN-F1 is the default hot key for this laptop to suspend/sleep. After pressing FN-F1 to suspend and then FN-F1 to wake it up, the sound start to work magically. This is however a very annoying solution as every time the laptop is started, a few seconds are needed to sleep it then a few seconds are needed to wake it up just to have the sound working. Even after the sound is working, the headphone is not working perfectly, sound can be heard from the earphone but the plug-in of the headphone to the jack does not disable the sound produced from the regular speakers.
The second problem is about the wireless network. NetworkManager (nm-applet) that sits on the panel can detect any Wifi hotspot but can not connect to it. To connect to the detected wifi hotspot, the following commands have to be typed in the terminal where eth1 refers to my wireless network card.
sudo iwconfig eth1 essid the_id_of_the_wifi
sudo iwconfig eth1 key the_password
sudo dhclient eth1
Luckily Ubuntu 8.10 Intrepid Ibex fixes these problems. The sound works right away. Headphone plug-in now disable sound from speakers. The latest NetworkManager has no problem connect to wireless network. I am very happy with these fixes and is now exploring any other improvements.
