F23 refuses to recognize tablet's existence

I just upgraded to Fedora 23 from F22 on my Lenovo X201 2-in-1, which comes with a Wacom tablet built into the monitor. (At least, that's what the sticker tells me.) Now that I've upgraded, though, the computer doesn't seem to recognize the tablet's existence. The monitor still works as a touchscreen, and I know that it's not a hardware problem because it still works on Windows 10 (I have a dual-boot). Is there a bug, or is there a setting I need to reset?

Maybe people need a little bit more information: could you do a lsusb | grep -i wacom and dmesg | grep -i wacom . Also you could try dnf install libwacom libwacom-data xorg-x11-drv-wacom . Just to make sure some of the proper software is loaded.

I tried the lsusb one, but I didn't get anything. However, when I typed dmesg, I got this: [ 8.320632] input: Wacom Serial Penabled 2FG Touchscreen as /devices/pnp0/00:05/tty/ttyS0/serio3/input/input14. The word "Wacom" was in bold red. Does that mean anything?

Bold in red, just means that's what grep matched. If you did a dmesg | grep -i Penabled then Penabled would be red. The dmesg output means that the kernel found the device and there should exist /sys/devices/pnp0/00:05/tty/ttyS0/serio3/input/input14 . Maybe instead of usb your Wacom Touchscreen is attached using pci . lspci | grep -i wacom . http://linuxwacom.sourceforge.net/wik... 2FG means 2-FinGer .

Typed your suggestion. Nothing came up.

Attachment by PCI would make sense, though, since it's a laptop and the monitor is probably hard-wired to the CPU.

And...it started working again! YAY!

I'm seeing the same problem on the same hardware, and thus filed a bug report here. However I'm not sure I filed it on the right component ("linuxwacom" vs the X11 driver, but AFAIK it also happens with Wayland)

To see the workaround I ended up using, check Comment 5 on the bug page. (It works for me.)
