[SOLVED] No Keyboard or Mouse in Xfce4

Hi All,

No keyboard or mouse at the display manager gui display. 
However, can ssh into the box and disable the display manager and boot into cli.
Its then possible to then run startx into xfce4.
However,  still no keyboard and the mouse cursor is stuck in middle of the screen.

After following instructions from https://forums.debian.net/viewtopic.php … 18#p718218
as in reinstalling xserver-xorg-input-libinput and reconfiguring udev, the keyboard and mouse are still unresponsive in gui.

here is apt policy file:  http://ix.io/4BGj
here is Xorg.0.log file:  http://ix.io/4BGl

thanks in advance for help to get this sorted!

Re: [SOLVED] No Keyboard or Mouse in Xfce4

xfce4 has it's own 'startx': /usr/bin/startxfce4. Here is the head (options at bottom):

  done

Perhaps try that?

Re: [SOLVED] No Keyboard or Mouse in Xfce4

if you're using ceres, rollback libgudev-1.0-0 to testing version. (237-2). latest debian version causes this for all systems using eudev (like devuan, antiX, etc).

Re: [SOLVED] No Keyboard or Mouse in Xfce4

thanks for the speedy replies!

alexkemp:
startxfce4 has the same result, as in no keyboard or mouse.
Due to the underlying gui framework been broken.

xonomilo:
Rolling libgudev-1.0-0 to 237-2 isn't as easy as sounds
libgudev isn't going quietly.
checking on libgudev-1.0-0 that is installed

rd@beanz:~$ dpkg -l | grep libgudev
ii  libgudev-1.0-0:amd64                           238-2                                  amd64        GObject-based wrapper library for libudev

attempting to downgrade to 237-2

rd@beanz:~$ sudo apt install libgudev-1.0-0=237-2
Reading package lists... Done
Building dependency tree... Done

Package libgudev-1.0-0 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Version '237-2' for 'libgudev-1.0-0' was not found

Attempting to remove libgudev-1.0-0

rd@beanz:~$ sudo apt remove libgudev-1.0-0

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libinput10 : Depends: libwacom9 (>= 2.0.0) but it is not going to be installed
              Depends: libinput-bin (>= 1.23.0-2) but it is not going to be installed
 libqt5svg5 : Depends: libqt5widgets5 (>= 5.15.10+dfsg~) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

Asking atp to remove libinput10, this would remove 230 packages and free 930MB!

I am unsure what to do next, other than getting a list of manually installed packages and rolling back to Daedalus or Chimaera.
Reading closer on the link you posted, looking like systemd is moving to stop non-systemd distros via udev.
Thanks again for your help.

Re: [SOLVED] No Keyboard or Mouse in Xfce4

add testing repo along with ceres.
then :
apt policy libgudev-1.0-0
should show both version, and :
apt install libgudev-1.0-0/testing
to rollback to a working version.

Re: [SOLVED] No Keyboard or Mouse in Xfce4

Hi xinomillo,
Thanks for the very helpful instructions, now I have a working machine!

The steps I did:
Get to a cli screen:
reboot to "recovery mode", enter root password and log in as root.
or via ssh in from another machine.

Assess using "less" /var/log/Xorg.0.log.
Using "/" to search for "EE" and find this error:

$ less /var//log/Xorg.0.log
.
[   458.417] (II) Loading /usr/lib/xorg/modules/input/libinput_drv.so

check apt policy for libgudev-1.0-0:

 $ sudo apt policy libgudev-1.0-0

 deb http://deb.devuan.org/merged/ testing-updates contrib non-free main non-free-firmware
 deb http://deb.devuan.org/merged/ testing-security contrib non-free main non-free-firmware

updated apt:

# apt update

checked apt policy for libgudev-1.0-0 and now 237-2 has been added

# apt policy libgudev-1.0-0

Re: [SOLVED] No Keyboard or Mouse in Xfce4

There was an upgrade to eudev posted today that looked like it might address the issue with libgudev-1.0-0.
I removed the hold on libgudev-1.0-0 and did update and upgrade.  Everything seems to be fine now.
I did a reboot and there was no problem with processing mouse or keyboard events.
