Acer Aspire 4820TG TimelineX Thread

[Amivit]

My Problems and Solutions so far for the Acer Aspire TimelineX 4820TG running Ubuntu 10.04 (32-bit).
I created this thread because this laptop is very new, but I see high potential in it and think more and more user will show up with the 4820TG aswell. Please share your solutions/problems and feel free to help me try solving any of these problems.
I am very new to linux and would love to start using it for real, but until I solve these problems I'm unfortunately going to keep on using Windows in my dual-boot setup.

Installation:Smooth!
Problem 1:Ethernet not working
Solution:
Download driver, specifically "AR81Family Linux Driver" from http://partner.atheros.com/Drivers.aspx.

tar zxvf AR81Family-Linux-v1.0.1.9.tar.gz
sudo su
apt-get install build-essential
apt-get install linux-generic-header
make install
modprobe atl1e

Problem 2:AC Adapter Status always showed as plugged in/Battery status not available
Solution:
???
Problem 3: Power consumption way higher than necessary
Because this laptop has switchable graphics, and I am only interested in using the low-power intel onboard and not the ATI 5470. Can't find out how to only use the intel and deactivate the ATI. Not possible through BIOS, only possible to deactivate the Intel to only use the ATI Getting 2 hours instead of the promised 5-8 hours.
Solution:
???

Hy I have the same notebook. I had already resolve the problem of Ethernet card. I don't know how to fix the battery problem, but I can help you with this:

Problem 4: Multitouch

1) create a file named .touchpad.sh in your home
2) open the file and copy these line into it:

#!/bin/sh

sleep 10
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Two-Finger Scrolling" 8 1
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 8 1 1
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 32 10
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Width" 32 8

The sleep time is necessary.
3) make the file executable with

chmod u+x ./.touchpad.sh

4) add the file file in autostart application: system->preference->autostart application

giova.86, awesome! I didn't even realize it wasen't working as I didn't even know the laptop had that feature. I testet it in Windows and it worked. After applying your fix it worked in Ubuntu aswell! One step closer to being able to use Ubuntu fulltime :b

Keep it coming people! One of the things I admire with the Linux community, everyone being able to help eachother ^^

Has anyone tried the following fix for mulitouch with Ubuntu 10.10? It's not working on my laptop for some reason. Perhaps it only works on 10.04.

EDIT: Nevermind, it seemed to have fixed itself. I fiddled with some settings using synclient which helped a little but did not completely fix the problem. I then restart the laptop and for all you know the thing works like a charm using the script below.

1) create a file named .touchpad.sh in your home
2) open the file and copy these line into it:

#!/bin/sh

sleep 10
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Two-Finger Scrolling" 8 1
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 8 1 1
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 32 10
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Width" 32 8

The sleep time is necessary.
3) make the file executable with

chmod u+x ./.touchpad.sh

4) add the file file in autostart application: system->preference->autostart application

Ok 2 issues:

Touchpad: I just discovered that contrary to what my post above says, my touchpad on the 4820t is not working properly. It seems to be a matter of luck really. Sometimes I restart and it's working great, other times when I put two fingers on it the mouse pointer goes nuts. Today for instance I sent it to sleep than after wake up it's working properly. I'm really at loss to what could be causing this.

Battery Indicator: When I unplug the charger Ubuntu does not know what happened at first and continues normally. However when I plug it in again and then take it out, it detects the battery is discharging. Anyone encountered this strange behaviour?
