Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.
Please add drm.debug=0x04 to the kernel command line, restart computer, and attach
* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log),
* all files in /etc/X11/xorg.conf.d/ directory,
* output of the dmesg command, and
* system log (/var/log/messages)
* output of the evtest against /dev/input/* (see in /var/log/Xorg.0.log the name of the file which is relevant for the touchscreen input)

there doesnt seem to be a event device.
/var/log/messages is empty.
there was nothing particular in dmesg except a lot of mail log.

Really, I cannot find one. I believe that we are on https://fedoraproject.org/wiki/Xorg/Input_Triage_Algorithm#How_to_spread_bugs_between_evdev.2C_-mouse_or_-keyboard_and_kernel step 1.
Could you please provide us with output of the command
(please, attach it, as it may be quite long),
Thank you in advance
There are aparently none of my wacom devices there.
The stylus does in fact work however.

I believe we should move the bug to the kernel component, but I will leave the final decision on the maintainer of Xorg copmonent.
Passing to developers.
Serial devices are currently still handled by the X driver directly (though we do have a serial kernel driver now). That's why they don't show up in /proc but the X log still shows them.
Either way, if it works at login but not after, this suggests that one of the gnome default settings seems to interact badly.
the schemas that matter are:
these contain the settings gnome applies after login. you can have a look at each schema's keys with
gsettings list-keys <schema>
and then get/set the keys with gsettings get/set <schema> <key> [value]
my first guess would be org.gnome.settings-daemon.peripherals.wacom touch, try enabling that.
gsettings set org.gnome.settings-daemon.peripherals.wacom touch true
Now If I could have multitouch working also :)
(actually the screen syntesizes scroll wheel events on a pinch gesture by default)

heh. not yet, not real MT anyway.

yeah, the wacom driver has some built-in gestures that work more or less, depending on what app is in focus.
I'm closing as NOTABUG though I admit that we need more documentation here. Matej, should we add this to common bugs or so?
just as a follow-up, we've changed the upstream gnome default to be true, not false for touch to avoid this issue in the future.
reopening, reassigning to gnome-settings-daemon, will submit an update shortly.
