    Re: Acer Aspire 4820TG TimelineX Thread

    It's amazing. You've done a great work. As i understood all now works fine after upgrading BIOS, installing acpi and doing steps written on http://asusm51ta-with-linux.blogspot.com/ . Even wifi and ethernet works? How long can a laptop run on battery power? Thanks.

    I'm having some issues getting bluetooth working(I cant seem to find the hardware, either in linux or Windows). is there some output from lshw or lspci that I should be seeing?

    Re: Acer Aspire 4820TG TimelineX Thread

    Anybody try run "switch_before_shutdown.sh" (or only echo ON > /sys/kernel/debug/vgaswitcheroo/switch) from http://asusm51ta-with-linux.blogspot.com/ in automatic shutdown with gnome-applet ?
    I try put script (echo ON > /sys/kernel/debug/vgaswitcheroo/switch) in rc0.d and rc6.d, but has not effect.
    P.S. Sorry for my English.

    My bt isn't working too and I have nothing about it in lshw, but dmseg write about some problems with initialization config files when Fn+F3 is pressed.

    Re: Acer Aspire 4820TG TimelineX Thread

    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.

    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
    Code:
    chmod u+x ./.touchpad.sh
    4) add the file file in autostart application: system->preference->autostart application

    Re: Acer Aspire 4820TG TimelineX Thread

    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?
