    This is probably not preserved over reboots

    We should seriously think about updating the wiki with all our findings

    Furtermore, I wonder if these things should be reported as bugs somewhere. Anyone with a definitive answer on that?

    I can say, that in the short time I have tested the palmdetection it works absolutely proper!
    Cool, I will try this

    PS: to preserve over reboots, just add the lines to ~/.xsessionrc

    Until the brightness Fn buttons work, I can highly recommend indicator-brightness. Works perfectly (you can use mouse scrollwheel when hovering the indicator).

    Re: Asus Zenbook Prime UX31A and UX32VD

    I found a 'better' way to persist the palmdetection settings.

    1. create a new file in /usr/share/X11/xorg.conf.d/ called '52-asus-zenbook-synaptics.conf'
    2. Paste the following in it
    Code:
    # Example xorg.conf.d snippet that assigns the touchpad driver
    # to all touchpads. See xorg.conf.d(5) for more information on
    # InputClass.
    # DO NOT EDIT THIS FILE, your distribution will likely overwrite
    # it when updating. Copy (and rename) this file into
    # /etc/X11/xorg.conf.d first.
    # Additional options may be added in the form of
    #   Option "OptionName" "value"
    #
    Section "InputClass"
            Identifier "touchpad catchall"
            Driver "synaptics"
            MatchIsTouchpad "on"
    # This option is recommend on all Linux systems using evdev, but cannot be
    # enabled by default. See the following link for details:
    # http://who-t.blogspot.com/2010/11/how-to-ignore-configuration-errors.html
          MatchDevicePath "/dev/input/event*"
    	Option      "CircularScrolling"          "on"
    	Option      "CircScrollTrigger"          "0"
    	Option      "PalmDetect"                 "on"
    	Option "PalmMinWidth" "4"
    	Option "PalmMinZ" "1"
    EndSection
    
    Section "InputClass"
            Identifier "touchpad ignore duplicates"
            MatchIsTouchpad "on"
            MatchOS "Linux"
            MatchDevicePath "/dev/input/mouse*"
            Option "Ignore" "on"
    EndSection
    
    # This option enables the bottom right corner to be a right button on
    # non-synaptics clickpads.
    # This option is only interpreted by clickpads.
    Section "InputClass"
            Identifier "Default clickpad buttons"
            MatchDriver "synaptics"
            Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0"
    EndSection
    
    # This option disables software buttons on Apple touchpads.
    # This option is only interpreted by clickpads.
    Section "InputClass"
            Identifier "Disable clickpad buttons on Apple touchpads"
            MatchProduct "Apple|bcm5974"
            MatchDriver "synaptics"
            Option "SoftButtonAreas" "0 0 0 0 0 0 0 0"
    EndSection
    3. save it, reboot, and you should have:

    * Palmdetection
    * Circular scrolling (a personal preference of mine, google it

    The script (and its updated version) fails with

    Code:

    Again no files (except 'version') in /sys/class/drm and the system won't boot properly (hangs on a purple screen) unless I start the recovery mode and then resume boot (which sometimes gives a 'swapper' related stacktrace.

    yes, this really seems to be a totally different case, cause i'm on 2.4GHz band only, and i've never tried the 5Ghz one. i don't know, if disabling n on a 5GHz band is a good idea at all. maybe there's someone else here, who can help you out with a 5GHz AP!?

    I am not entirely following this, but I am connected to a N accesspoint and this seems to work properly

    Re: Asus Zenbook Prime UX31A and UX32VD

    Warning: You might nog want to update when running quantal, doing so has removed my ability to change brightness

    Something in quantal probably broke.

    Edit: Suspend/resume is also defective, which always seems to happen in conjuction with brightness being defective. Using xorg-edgers makes no difference.

    synclient PalmDetect=1
    xinput set-prop "ETPS/2 Elantech Touchpad" "Synaptics Palm Dimensions" 4 1
    This works pretty good, but for me the following works a bit better:

    Code:
    killall syndaemon
    syndaemon -i 1.7 -d -t
    That mean's that all clicks are disabled for 1.7 seconds. Maybe the best setting is a combination of both.

    Btw, I'm using kernel 3.4.4 (mainline-kernel).

    Re: Asus Zenbook Prime UX31A and UX32VD

    @ Maroony, will try that later, but first:

    I have tracked down the source of my system not booting and the kernel panics:

    the asus-wmi patch (http://comments.gmane.org/gmane.linux.kernel/1315719)

    When I boot, the process hangs forever in the dotted ubuntu splash. When I boot in recovery mode however, and then choose 'resume boot' everything works fine. This might have to do with some race condition occuring, but thats up to the programmers

    When I booted through the recovery mode method the asus-wmi module works (I can use the functionbuttons) but for some reason this also prevents DRM from properly loading, and thus /sys/class/drm/ is not populated, which in turn means you can not use external monitors, waking from suspend does not work (screen stays black, with no way to turn it back on) and setting the brightness of the screen is not possible through the gnome-settings or xbacklight/xrandr. The intel_backlight utility hoewever still works.

    I am booting from an SSD so people using the HDD as root might not have this problem. If you want to remove the patched asus-wmi module, run the following:

    Code:
    sudo dkms remove asus-wmi/999.01 --all
    I added some entries to the wiki: https://help.ubuntu.com/community/As...ev2=28&rev1=27

    Furthermore: also see my entry on nomodeset, when I boot using nomodeset I get exactly the same issues as described above. I also updated the wiki about it: https://help.ubuntu.com/community/As...ev2=29&rev1=28
