Touchpad problem Ubuntu 18.04

[voodoolovedog2]

It's been a long time since I've visited these boards. Most of the time I can find a solution to my problem without posting, however now I need a little help.

I'm trying to get Ubuntu 18.04 working on a Panasonic Toughbook CF-53. I'm almost at the finish line because almost every device worked right out of the gate. However, the touchscreen is not working at all. Poking around I dug up the information to resolve the issue but it seems that Ubuntu is confusing the input values between the touchpad and the touchscreen.

xinput doesn't show the device at all:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ USB2.0 Camera: USB2.0 Camera id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
↳ Panasonic Laptop Support id=12 [slave keyboard (3)]

dmesg told me that the hardware was found:

dmesg | grep -i touch

and there's where it hit me. The touchpad is on input9 and the touchscreen is on input11. But xinput has assigned the touchpad input11, thus ignoring the touchscreen.

Selective cat from /proc/bus/input/devices

So how to I force Ubuntu (or xinput, I guess) to assign the touchpad to input9? Which I guess would then allow the touchscreen to take input11?

Thanks for your time.

Try

sudo apt install xserver-xorg-input-synaptics

and reboot.

Despite the title of this thread I believe this is really more about a touchscreen issue than touchpad....

But to answer your question I believe there is some issues and it to an extent depends on the DE you use. Mostly Ubuntu seems to have migrated to libinput but Xubuntu doesn't work 100% correctly with this driver and comes with the synaptics one (or so I believe.) I run Studio, which should be based on Xubuntu but came with libinput and i was having weird issues (main one being scrolling upwards was very temperamental) so had to manually change it to use the synaptics one. Once I had done that I have absolutely zero issues (and generally haven't since I started with Ubuntu with 14.04)

Jumping mouse and extra clicks I read is usually caused by two drivers trying to control the same device. running xinput should give you an indication if this is the case for you.

Apologies to voodoolovedog2 for replying to the off topic conversation in your thread. Wish I could help you with your issue but I have no idea. bodhin2 please start your own thread if you wish to talk about such things more.

Try

sudo apt install xserver-xorg-input-synaptics

and reboot.

I eagerly ran this command and was very hopeful it would resolve my issue, but it doesn't. The OS still "sees" the touchpad as input11 even though it's listed in /proc/bus/input as input9. xinput still does not display the touchscreen.

Hello,

Is there a solution for this problem ? I experienced similar issue on a HP Zbook Studio G5.

Hi,

if it's anything like the touchscreen on my CF-19 (which the dmesg output suggests it is), what I had to do was to install xserver-xorg-input-evdev, and purge xserver-xorg-input-libinput. (just installing evdev was not enough)
