Synaptics Update breaks Elantech on eeePC ?

Rorschach · 2008-12-01 09:50:34

Hi,
I upgraded the synaptics package this morning and have to report that it seems to break the elantech-driver?

Using the touch-pad is terrible slow, also adjusting it with gsynaptiics doesn't work. Tabbing and Scrolling don't wortk either. Anyone knows what the problem here is? Maby we ccan work out a fix for it.

I compiled the elantech driver firm into the vanilla kernel 2.6.27.7 and before the upgrade of synaptics this morning everything worked fine. So something happened with this upgrade.

You need to translate the configuration in xorg.conf to the hal one. Moreover you need to explicitly enable tapping and sliding (this was not needed before). See: http://wiki.archlinux.org/index.php/Xor … ouchpad.21

Hi patroclo7,
thanks for your hint but I sat AutoAddDevices to false. Do I still need to translate my xorg.conf to hal?

Here's my xorg.conf: http://de.pastebin.ca/1272551

And the Xorglog contains this output:

So there's a warning at the end but google doesn't give me any hits on it... is this all related to the hal<->Xorg issue also if AutoAddDevices is switched off?

No but you need to add explicitly the tapping in xorg.conf. Look in 'man synaptics' for the needed options. This was not needed before: it is not a change related to hotplugging, but a change in the synaptics driver. Hotplugging merely determines the configuration files you need to edit

As you can see in my xorg.conf tabbing is explicitly declared And it's working 1 out of 15 times. So it's just damn slow as the whole touchpad became terribly slow in usage with the new synaptics driver. I mean it's unusable slow. To move the cursor from one end of the screen to the other takes about a minute

Hello, this is my first post here.
I've spent all afternoon getting my touchpad working again.
Now my speed is correct (fast) and side scroll is working again.
Try this in your xorg.conf.

Section "InputDevice"
Identifier "synaptics"
Driver "synaptics"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "LeftEdge" "1000"
Option "RightEdge" "5400"
Option "TopEdge" "1000"
Option "BottomEdge" "4900"
Option "PalmDetect" "0"
Option "SHMConfig" "true"
Option "SendCoreEvents" "yes"
Option "HorizEdgeScroll" "1"
Option "VertEdgeScroll" "1"
Option "RBCornerButton" "0"
Option "RTCornerButtom" "0"
Option "MaxSpeed" "0.9"

# You will also need the following 3 lines if you're using Xorg 1.5RC6 or newer
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
EndSection

I hope it works for you as it has for me.

That's the only diffrence to my xorg.conf and yes, the "mousespeed" is fast enough and scrolling does work, but tapping (leftclick, middleclick, rightclick on the touchpad) doesn't work for me.
