Touchpad often not detected on HP 625

[ibruell]

Often when I boot my laptop in battery mode, the touchpad is not detected correctly or sometimes not detected at all. So I have to reboot the machine.

The kernel detects it correctly I think

I tried the following with /etc/X11/xorg.conf.d/50-synaptics.conf:

Code: Select all

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        Option "Protocol" "event"
        Option "TouchpadOff" "0"
        Option "TapButton1" "1"
        Option "VertEdgeScroll" "1"
EndSection

Most the time I boot the laptop supplied to power the touchpad is correctly detected.

Before I installed Linux Mint LMDE I have used Ubuntu 10.10 without problems.

I have linuxmint debian 201204 installed.

Anyone an idea ???
