Dear Maintainer,

the Debian installer does not contain the synaptics driver for touchpads
(xserver-xorg-input-synaptics). Therefore the touchpad does not work in
the graphical installer.
I think the driver should be added to the gtk/initrd.gz.

Best regards,
Andreas

Andreas Cadhalpun <andreas.cadhalpun@googlemail.com> (2014-01-04):

Err. It should work with evdev (without touchpad-specific features
though). Can you please clarify what you meant?

Mraw,
KiBi.

Hi KiBi,

I just meant, that the touchpad cannot move the cursor, although evdev
is loaded.
But when task-desktop is installed, this installs the synaptics driver
and then the touchpad works.

Best regards,
Andreas

Andreas Cadhalpun <andreas.cadhalpun@googlemail.com> (2014-01-04):

Might be a kernel or driver bug. Can you please attach Xorg log and
kernel log from the installer?

Mraw,
KiBi.

I attached Xorg.0.log and syslog, but I found no related error messages
in them.
Also I realized that the left mouse button at least is working.

Andreas Cadhalpun <andreas.cadhalpun@googlemail.com> (2014-01-04):

It would be nice to know how it goes with a 3.13-based installation
image. (No need to test the whole installation, just trying to
figure out if there's still something that needs fixing.)

Daily d-i builds or upcoming jessie alpha 1 images should be enough
to make sure.

Mraw,
KiBi.

As it has worked fine on this machine all the time since introducing the
graphical installer with X.Org (Great work Kibi BTW :-) ) Just double-
checked with a 7.1 netinst CD.

Hi,

Unfortunately, moving the cursor still doesn't work. :(

Quoting Andreas Cadhalpun (andreas.cadhalpun@googlemail.com):

Which reminds me, indeed, that I had the same exact problem with that
image on a Dell Letitude E7240 (my brand shiny new laptop while
installing Debian jessie with KDE on it which, by the way, worked exactly as
expected).

So, in short, for once, I can help investigating it...:-)

From my /var/log/messages:

It would then be helpful if it worked for you with older images / with
older kernels?
Did it work with wheezy images?

Hi,

It seems so.
synaptics: Touchpad model: 1, fw: 8.1, id: 0x1e2b1, caps:
0xd00123/0x840300/0x127c00, board id: 2334, fw id: 1508589

And from Xorg.0.log:
evdev: SynPS/2 Synaptics TouchPad: Found absolute axes
evdev: SynPS/2 Synaptics TouchPad: Found absolute multitouch axes
evdev: SynPS/2 Synaptics TouchPad: Found x and y absolute axes
evdev: SynPS/2 Synaptics TouchPad: Found absolute touchpad.

It works with the wheezy 7.1 CD.
Maybe it has to do with mtdev? The following line is in the jessie
Xorg.0.log, but not in the wheezy one.
evdev: SynPS/2 Synaptics TouchPad: Using mtdev for this device

Also the 'Found absolute multitouch axes' is not present in the wheezy
log (attached).

Best regards,
Andreas

There is no mention of this "mtdev" in my Xorg.0.log (attached).
So that's maybe related, why it works here.


Holger

Hi,

the problem is, that I can't move the cursor with my touchpad in jessie
installers, while it works with wheezy installers.

It seems that the problem is caused by the new multitouch support (mtdev).

Best regards,
Andreas

I have the same issue with my HP Probook 4510s and the Debian 8
graphical installer.
