Synaptics driver problems
xlock and xscreensaver

Synaptics driver problemsContents

After upgrading from sarge to etch and replacing XFree86 with Xorg I had problems with the synaptics touchpad driver. From my log:

(II) LoadModule: "synaptics_drv"
(II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so
(EE) LoadModule: Module synaptics_drv does not have a synaptics_drvModuleData data object.
(II) UnloadModule: "synaptics_drv"
(II) Unloading /usr/lib/xorg/modules/input/synaptics_drv.so
(EE) Failed to load module "synaptics_drv" (invalid module, 0)

The problem was simply that to load the module you have to:

        Load    "synaptics"

and I had:

        Load    "synaptics_drv"

in my xorg.conf.

xlock and xscreensaverContents

xlock disappeared in Debian Etch. xscreensaver can be used instead, but it works is a client-server application. Start it in the xsession with: xscreensaver -no-splash& and lock the screen with xscreensaver-command -lock.
