    Re: Asus U43JC

    Hey dsfitzpat, thanks for the info! It turns out the throttling went away when I changed the power saving settings on Windows. Will give that utility a try; it is somewhat vexing that there are BIOS settings that can only be configured from Windows. I hope this doesn't become a trend!

    Re: Asus U43JC

    It would be interesting to know if the eee-control-applet works on the full-size Asus notebooks - especially since it seems to me like these are getting better all the time, and usually offer better specs and/or lower prices! I did a quick search and came across another program called Jupiter that claims to do the same thing, and has the advantage of coming from a PPA:
    http://www.webupd8.org/2010/06/jupit...sus-super.html

    I'm not sure if Asus still calls this Super Hybrid Engine on their notebooks but the above site claims this tool works on any laptop, so maybe it's worth a try. Somewhere in the Asus Eee support forums they claim there's a version of Super Hybrid Engine for Linux; maybe they ported it to Xandros (the OS on the original Eees) but I haven't come across it.

    I have jupiter installed on my U43JC, but AFAICT it does nothing. I hacked its scripts to have visual feedback when enabling/disabling the touchpad (see first post), but that's it.

    Can you tell me how to go about patching the DSDT.dsl file?

    Re: Asus U43JC

    After executing the first code block in the OP's HowTo you should have a DSDT.dsl file. Copy the second block to a file dsdt.diff in the same directory and run patch < dsdt.diff

    Tremendous work! Thanks for this great howto. Mostly everything worked just as described and brought my Asus to live under Ubuntu.

    The only thing I noticed stopped working is a cd/dvd drive. It stopped mounting disks with the message:

    Code:
    $ sudo mount /dev/cdrom /mnt
    mount: unknown filesystem type 'iso9660'
    It appeared that module isofs (as well as other cd/dvd fs support) was kicked out from my custom kernel. I figured out that the reason they were disabled was the following line in making new kernel configuration:

    $ make localmodconfig
    I simply skipped this line and recompiled the kernel with modules from original Ubuntu's /boot/config-VER (adding DSDT of cause) and everything worked.

    I suspect there might be other important modules kicked out by localmodconfig, I just did not notice by this time.

    I also had trouble with the localmodconfig and used make oldconfig as directed in the HowTo. Takes longer to compile and gets you a few more GB of temp files, if I remember right, but is probably safer. You can also try to speed things up with make -j 4 (after all, we ought to be able to do hyperthreading)

    Re: Asus U43JC

    Hey dudes,

    23kota: I removed the "make localmodconfig" line from the howto, it really was causing more problems than solving them! Substitute it with 'yes "" | make oldconfig' for better results (but much longer compile times .

    rosenkrantz: The -j4 thing is taken care of by this on the compilation line: "CONCURRENCY_LEVEL=`getconf _NPROCESSORS_ONLN`"

    Re: Asus U43JC

    Just followed the tutorial and it was great! Very well done!
    Thanks so much, it felt way too weird too have a worst battery life on Linux than on Windows lol

    I have a little question: my battery's "current state" is more in the 19000mW than in the 13000mW.

    The first time I followed the tutorial (I've done it twice) and BEFORE I applied the patch to automatically disable the nvidia card, it went exactly around 13000mW. As soon as I applied the patch and reboot, it was back at 19 or so....

    BTW, is it normal that we are using a G210m file whereas our card is actually a G310m?

    Also, the "jupiter-support-eee" cannot be found through the given command...even the command that the actual site gives me is wrong, I guess the package has been removed...

    Anyhow, thanks a lot for all the effort put into this, hopefully my battery life will be much better!

    Hi gravufo!

    What the g210m module does is simply run the acpi_call command automatically at boot (and at resume from suspend). If you're getting 19000 mW after rebooting, this could mean a couple of things:

    1) The module isn't being loaded: run "lsmod | grep g210" and see if it's there. If it isn't, check your /etc/modules file and see if "nvidia_g210m_acpi" is at the end.

    2) The kernel wasn't patched with a custom DSDT, which is required for the U43JC.

    It doesn't matter if you have a g310m, by the way (which is what I have).

    Will look into the jupiter-support-eee, thing. Maybe it was renamed?
