Description Laurent Caruso 2013-10-24 06:06:55 CEST

DELL XPS 15 l502x

No mouse plugged to the laptop

Cauldron (alpha 3) Installation

DELL XPS touchpad is way too sensitive during the installation wizard.
When using thevtouchpad to move the mouse on the screen, very often the touchpad behaves as if a "tap" has been done to it (equivalent to a left click). 
This is problematic especially when editing partitions: when the user wants to delete a specific partition but the touchpad has accidently focused on another partition, there is a high risk that a wrong partition is deleted.

Please note that the touchpad behaves as it should once the installation is completed. 
I have noticed the same issue while trying to install Debian on my system, so this problem doesn't seem specific to Mageia.

Is there a possibility to lowered the touchpad sensitivity during the installation wizard?  This would make Mageia more user-friendly.

Is it a synaptic one?
We don't load that driver during install. We only load mouse & keyboard generic drivers (one exception being under VMWare where we load the special driver).

Yes Thierry, this is a Synaptic one.
Comment 3 Thierry Vignaud 2014-05-10 17:11:32 CEST
Indeed, we no more load the Wacom X11 driver since switching from XFree86-3.x to 4.x (long time before X.org):

I guess these days we should try to ship conf sniplet with drakx (/usr/share/X11/xorg.conf.d/50-synaptics.conf) & let X.org loads it.

Colin: would that be enough?
BTW, I should really switch the installer from mouse+keyboard drivers to evdev driver like after installation...

> Colin: would that be enough?

I guess so. All the other udev-fu is there these days so X11 should just be able to use it. I guess there could be a few udev rules we're currently missing to include too, but that should be easily resolvable.

Using evdev sounds like a good plan.

    don't write input sections in xorg.conf
    for eg: USB wacom tablets, mouses & keyboard (we were missing Synaptics
    We now rely on evdev/udev for input devices, which should make Synaptics
    touchpads to now automagically work during install (mga#11524)

Should be fixed as of 16.31.1 (once it lands on your favorite mirror)

Resolution: (none) => FIXED

Comment 7 Thierry Vignaud 2014-08-17 16:51:26 CEST
BTW Can you confirm it's OK with current cauldron or with Mageia 5 alpha1?
