I have a touch panel which identified as _D-WAV Scientific Co., Ltd eGalax TouchScreen_ on `lsusb` output.

While in the Debian 9 graphical installation screen, I’ve successfully used touchscreen, it is working very well.

But, after installation when I logged in the X session, touchscreen not working.

I see following error on `/var/log/user.log`:

```auto
libinput error: libinput bug: Device 'eGalax Inc. USB TouchController' 
does not meet tablet criteria. Ignoring this device

```

I can also find similar reports on the net but the no solution. Why it is working on the installation but not working on the installed system after?

Switching to **libinput** maybe a good idea on long term, but it still has some problems.

Other distributions switched to libinput too, it is not a Debian specific problem.

Here is a quick workaround for you:

- Install the `xserver-xorg-input-evdev` package
- Append following config block to `/etc/X11/xorg.conf` file (create the file if it is not exists before)

```auto
Section "InputClass"
	Identifier "evdev tablet catchall"
	MatchIsTablet "on"
	MatchDevicePath "/dev/input/event*"
	Driver "evdev"
EndSection

```

Then reboot your system and don’t forget to say “thanks” to me 🙂
