    Re: Acer Aspire 4820TG TimelineX Thread

    Ah, ok. I understand. I've had quite a few problems with Flash and the like. It was magically working in Chromium on another computer, so hopefully I'll be able to replicate that. Not holding my breath though.

    Hope it works for you.

    I use the kernel you provide , two questions

    · linux-image-2.6.35-7-generic_2.6.35-7.11~lucid1.3v1ubuntu2~toi2_amd64.deb
    · linux-headers-2.6.35-7_2.6.35-7.11~lucid1.3v1ubuntu2~toi2_all.deb
    · linux-headers-2.6.35-7-generic_2.6.35-7.11~lucid1.3v1ubuntu2~toi2_amd64.deb

    1. I can not find the switcheroo in the /sys/kernel/debug/.../vga_switcheroo file to enable the switch graphic card function.
    2. Is this kernel provide both vga cards driver ? I can not change the "extra" in the "Visual Effects".

    Is any procedure I need to follow ?
    BTW, my timelinex 4820tg BIOS upgrade to version 1.13 , is this cause the problem ?

    This is very strange... Are you sure that you've installed it correctly? the uname -r command should give back you something like Linux <hostname> 2.6.35-7-generic #3v1ubuntu2~toi1 SMP Wed Jul 14 01:31:07 CEST 2010 x86_64 GNU/Linux
    BTW the sys-node is in fact /sys/kernel/debug/vgaswitcheroo/switch !

    By default the notebook uses the integrated Intel card to run X (check /var/log/Xorg.0.log), so all the effects should be provided by the opensource intel driver... All the effects work to me (also if some plugins, like the blur one are too invasive).

    I've never tried to run the flgrx driver, but it should run (maybe using the previous mentioned workaround)

    My Aspire came with that BIOS and everything worked like I've described. I've updated also to BIOS version 1.15 (using freedos, since I've no Windows partitions in my NB) and nothing changed from the user point of view!

    About the pre-compiled kernel not having the switch:
    I don't remember if I mentioned it in this thread already, but I had the same problem, forcing me to compile my own kernel.

    @ks_b
    I have posted a post in this thread previously with links to a few tutorials which show how to compile a custom kernel. Do not be afraid, it's not that bad. It just takes time to compile.

    If you need step-by-step instructions, I will try to remember exactly what I did. Do not hesitate to ask.

    Try to do (if you don't have the debugfs mounted at all, and so no /sys/kernel/debug sysnode):
    Code:
    sudo mount -t debugfs none /sys/kernel/debug

    Re: Acer Aspire 4820TG TimelineX Thread

    As that was mentioned in this thread before, I had already tried it. /sys/kernel/debug was already mounted, but the vgaswitcheroo directory was not there.

    It's no big deal, it's all working for me now.

    Re: Acer Aspire 4820TG TimelineX Thread

    @Trevino :
    Thanks your response,
    I fix the problem. The root cause is
    1. If we upgrade the BIOS from 1.04 to 1.13 or 1.15, we need do one thing is "Load the BIOS default value first". I lose my Bluetooth after I upgrade to 1.13. after I "Load the BIOS default value" my Bluetooth come back again.
    2. the BIOS setting must be "Switch " , the vgaswitcheroo will show in the /sys/kernel/debug/.../switch

    Now I meet another problem , the VGA card can not switch. Someone meet the same situation like me .
    Any suggestion ?

    @ All:
    Thanks all you done..

    The switcher is OK now , Just need to exit to the and login again .
    Intel integrated vga work perfect, but when I with to the ATI Radeon card . It's need a driver .
    So I install the driver, but failed.
    I can install it on kernel 2.6.32 perfectly , but the when kernel upgrade to 2.6.35 it will cause errors.
    I think it the vga card driver problem .
    @All
    Is anyone successfully install the flgrx on 2.6.35 kernel ? or where I can get the newest flgrx driver?

    I've never tried to run the fglrx drivers yet... I had no time for trying them. However maybe they don't support the new kernel yet (damn, closed drivers!)
    However if you want use the intel card by default saving power (and temperature), you can use scripts like these: http://forum.ubuntu-it.org/index.php...tml#msg3101266
