Hello,

I have two hosts (x86_64) & (x86) running and after apt-get dist-upgrade
this morning, I can no longer use my keyboard/mouse on either after a
reboot on both machines?

Has anyone experienced anthing similar?

On the x86 host it is ps2(kbd)+usb(mouse).
On the x86_64 host it is usb(kbd)+usb(mouse).

Appears to be a known issue:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=364932

Well here is the fix:

Quote:

The evdev X driver can't work if the CONFIG_INPUT_EVDEV option is disabled
in your kernel configuration. You'll have to either enable this kernel
option, or disable the "AutoAddDevices" option in xorg.conf.

# grep CONFIG_INPUT_EVDEV  .config
# CONFIG_INPUT_EVDEV is not set

Trying now.


So this fixes the issue (w/ the kernel config option); to where I can use my
keyboard and mouse. however, now there is an annoying lagging with the
mouse cursor, I will remove this and try the AutoAddDevices option in
xorg.conf
to see if it fixes it.

I have been using the following mouse setting for many years:

xset m 20/5 1

It no longer works the same anymore either with the new X server (I am
guessing this is the culprit) however I will try the AutoAddDevices and
disable the kernel event interface to see if this returns the mouse
acceleration back to normal.

Justin.


Update again: Without the kernel option, the 'auto' option for xorg.conf
did not work, so my question to the debian-user@ list and xorg@ list is
how do I get my old mouse settings back?

xset m 20/5 1 which I have been using for a decade++ no longer yields the
same results for the mouse cursor, before, the acceleration was immediate
and it stayed the same throughout the cursor movement.  now, when I move
the mouse slowly to highlight text for example, it moves 1/3 the speed as
usual and only speeds up when I move the mouse much faster.

I can downgrade back to an earlier version of Xorg but I was wondering if
there was a proper fix for this problem?  Is there a document on the new
settings that makes it so xset m 20/5 1 no longer yields the same
acceleration/movement etc as it used to?

ii  xorg                                 1:7.4+4                    X.Org

ii  xserver-xorg-input-mouse             1:1.4.0-4                  X.Org
X server -- mouse input driver

The docs in /usr/share/doc/xserver-xorg-input-mouse do not yield and
useful information.

Appears to to affect others as well:

Still looking for a fix/work-around.

Still have not been able to make the cursor behavior like it once was, however.
