    Re: Acer Aspire 4820TG TimelineX Thread

    how did you put the "wl.ko" file to the /lib/module directory? did you copy it or did you do "make install" ?

    Re: Acer Aspire 4820TG TimelineX Thread

    OK, I solved it. I had installed kernel linux-image-2.6.35-7-generic_2.6.35-7.11~lucid1.3v1ubuntu2~toi2_amd64.deb and it some have did not work. I changed it for linux-image-2.6.35-7-generic_2.6.35-7.11~lucid1.3v1ubuntu1_amd64.deb and now it works. There are still some problems with suspend mode but that I will try to resolve later when I will have more time.

    Where'd you get this kernel from?

    Re: Acer Aspire 4820TG TimelineX Thread

    thanks to Trevino, his kernel (http://ubuntuforums.org/showpost.php...0&postcount=52) get my lovely computer work fine.

    But I still have two majors problems :
    1 - on battery time : just 2 hours...

    2 - fans : they are always on... may be cause for 1...

    some searches on 2 give me :
    Code:
    - sudo pwmconfig

    ==> /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

    Code:
    - sudo sensors-detect

    ==> Sorry, no sensors were detected.

    and
    Code:
    - sensors

    ==>
    acpitz-virtual-0
    Adapter: Virtual device
    temp1: +54.0°C (crit = +105.0°C)

    Any other in front of that ?
    Any guru to give a workaround ?

    Thanks for any help

    I had the same problem but went into the BIOS and switched the Graphics mode from 'switchable' to 'discrete'. I don't know exactly what that means but it loads alright now and I can get to the catalyst control centre alright.

    Update. Oops, just saw #72.

    Ah, sorry I wasn't around to help you guys with your wireless problems. I thought I had made a post about the need to compile new wireless drivers but I guess not. Also, I was able to bind the command "eject cdrom" to a keyboard shortcut using ubuntutweak in order to allow me to open the drive.

    Has anyone been able to get the discrete card to shut off on startup? I have had to do this manually and it's a bit of a pain...I believe you can get about 5 hours if the discrete card is off. However, I think the claim of 8 hours applies to other models in the TimelineX series and not the one I have. Has anyone actually been able to get 8 hours, even in windows?

    @Mike81
    Discrete mode in BIOS will turn off the integrated video card and only enable the discrete card. This will give you better performance, but worse battery life. Also, you will be unable to switch back and forth in windows, if that is an issue.

    Re: Acer Aspire 4820TG TimelineX Thread

    Shutting off the discrete card worked for me with this guide: http://asusm51ta-with-linux.blogspot.com/
    Some easier ways failed, most times I wasn't able to use my mouse or my keyboard after a reboot.


    I get about 7 hours (discrete card off) on Ubuntu (with 60 Wh). But this was only doning some simple tasks, watching a DVD gave me only 3 hours, listening to music maybe 5? Don't remember.

    Also I don't have a usual install, I installed Ubuntu Server and did 'sudo apt-get install ubuntu-desktop --no-install-recommends' -- this way I only have the software I really need and not too much running in the background. Plus the Server version is more power-saving (of course )

    Maybe not the easiest way but getting 7 hours is possible
