[Bob <sooner@xxxxxxxxx>]

Don't remember where I found these tips, but they aren't mine!  However, they do work on my Aspire One.





Fan:



With A110 and UNR v9.10, (late 2009 release), the only thing needed to be changed from the vanilla install is to edit /etc/modprobe.d/acerhdf.conf and add the line: options acerhdf kernelmode=1 then reboot. This controls the fan and is worth swapping to ubuntu just for this, the netbook is then silent apart from the sound made by using the keyboard..



The default temps are a bit high, so if you notice your device getting too hot, you can adjust the temp that the fan turns on and off by adding a few parameters to the options line above. The following seems to prevent it from running too hot: 'options acerhdf kernelmode=1 fanon=61000 fanoff=54000' See http://piie.net/files/acerhdf_README.txt for more info.



(N.B.- http://piie.net/files/acerhdf_README.txt has not yet been updated to reflect that ubuntu now expects the temperatures to be specified as '61000' rather than the former '61'.)



As described the battery status will take bit of time to update when you unplug the AC cord, but if you wait 30 seconds it will change, which I can live with. The second Wifi LED that indicates traffic does not flash, but again that's no great loss.



Suspend mode will hang if a MM/SD/SDHC card is mounted, if you don't like the excellent script below then you can unmount it from the Nautilus file manger, or physically pop it out, if you're 100% sure it's not is use. In the script below I have to change /dev/mmcblk?p* to /dev/mmcblk*



If you try and suspend with a card mounted then you'll have to hold down the power button for five seconds to power off.



Power manager status icon in the Notification Applet does not switch from AC power to Battery when unplugged, although the screen dims. Since it still shows as AC power, it does not show an estimate of battery time left. If it is unplugged at login, it will switch to AC power status when plugged in, but not back if unplugged again. A work around for this is to add the add the following line in /etc/rc.local before the exit 0 line



    *



      /etc/init.d/laptop-mode start

      service laptop-mode status



Suspend Mode with SD cards mounted: The system hangs when the suspend mode is entered with SD cards inserted. The following script will unmount these SD cards. All SD cards will be automatically mounted again after resume. The suspend mode is not entered when there are programs that still access the SD cards. There are no more system crashes with the following script. Create one named /usr/lib/pm-utils/sleep.d/010_unmount_SD.sh as user root. Make it executable with chmod 755 /usr/lib/pm-utils/sleep.d/010_unmount_SD.sh. This script should contain the following lines:



# Drop to: /etc/pm/sleep.d

# Use this script to prevent data loss on mounted MMC/SD

# cards. It syncs data and umounts all mmcblk devices prior to

# suspend, and cancels suspend if umounting was not possible

# (i.e: something locks a file)

case "${1}" in

    hibernate|suspend)

        /bin/sync

        for drive in $( /bin/ls /dev/mmcblk?p* ); do

            /bin/umount ${drive} > /dev/null

            # If umount failed: abort suspend

            if [ $? -gt 0 ]; then

            # Test if device keeps mounted. Previous command could fail

            # (i.e device was not mounted) with a non-stopper

            # problem for the suspend process.

            /bin/mount | /bin/grep ${drive}

            if [ $? -eq 0 ]; then

                exit 1

            fi

            fi

        done

        ;;

#    resume|thaw)

##       Do nothing. All devices will be automatically mounted again.   

#       ;;

esac
