 Posted: Thu Nov 29, 2018 8:20 pm Post subject: [solved] UC-LOGIC WP8060U graphics tablet driver |
 |
|
Hello,
I am trying to get the Genius MousePen 8x6 UC-LOGIC WP8060U graphics tablet working using wizardpen driver (https://launchpad.net/wizardpen). I am using ebuild from jm-overlay (http://gpo.zugaina.org/x11-drivers/wizardpen). I had it working few months ago using this driver. I think that some upgrade messed it up.
I am not realy asking for help with this particular driver. My question is more general about X11 modules. I am sure I will be able to work it out somehow. But I there are some things I need to learn to do that.
The driver works as a xorg plugin. It comes with its udev rules file - /lib/udev/rules.d/67-xorg-wizardpen.rules (mine is the Genius MousePen 8x6 Tablet).

ENV{x11_driver}=="wizardpen", KERNEL=="event*", ENV{ID_INPUT_TABLET}="1"

And it also has a xorg conf file - /usr/share/X11/xorg.conf.d/70-wizardpen.conf:
| Code: | Section "InputClass"
Identifier "wizardpen"
MatchIsTablet "on"
MatchDevicePath "/dev/input/event*"

Option "TopX" "1506"
Option "TopY" "2705"
Option "BottomX" "31225"
Option "BottomY" "30892"
EndSection |
When I plug the tablet in, xorg crashes. And this is printed to journalctl:

My interpretation is that the wizardpen driver crashes due to `xf86OpenSerial: Cannot open device /dev/input/event6 Permission denied.` message. But the crash is not fatal. This somehow messes up udev which then causes fatal crash when trying to configure the next device (logitech mouse). Whish seems strange to me. Can you tell me more about what can be happening there?
The main question I want to ask is however about the `xf86OpenSerial: Cannot open device /dev/input/event6 Permission denied.` message. What problem can this indicate? When does the xserver reports this problem? My user is in the 'input' user group so there should not be any problems there. And when I try `cat /dev/input/event0` as a user, there seems to be no problem (nothing is printed, but no Permission denied errors). I don't know, I am lost here. I do not know where should I try to solve this prolem. Which part of the system might have a problem that would cause this?
I do not need full solutions from you. I just need to know more about how the xorg drivers are incorporated into xorg, what does the xorg need to have good permissions or what parts of the configuration are capable of causing this error.
Thank you,
Ivorne

| Well if you're insistent on using a driver that hasn't been maintained for close to a decade instead of libinput... try using an X server of a similar vintage. |

Well I did not know that I can use libinput for that. But thanks to you, I now know that. We need to write it to a wiki. Because trust me, I spent a lot of time researching this and I had no clue.
But I guess the only emotion I am justified to feel now is relief and gratitude towards you. So thank you.
And the solution is to firstly have libinput installed. But it does not work out of the box. `libinput list-devices` prints 'event17 - UC-LOGIC Tablet WP8060U: libinput bug: missing tablet capabilities: resolution. Ignoring this device.'. So I googled around and found out that the problem is that the there is no record in '/lib/udev/hwdb.d/60-evdev.hwdb' for this tablet. So I found the evdev id or whatever is that called for the tablet (https://askubuntu.com/questions/742946/how-to-find-the-hwdb-header-of-a-general-input-device) - it is 'evdev:input:b0003v5543p0005*'. Then I created file '/etc/udev/hwdb.d/61-evdev-local.hwdb' with following content:
| Code: | #########################################
# UC-LOGIC
#########################################
# UC-LOGIC Tablet WP8060U
evdev:input:b0003v5543p0005*
EVDEV_ABS_00=::234
EVDEV_ABS_01=::328
|
I don't know what the two numbers 234 and 328 are, but the tablet works fine now. Even pressure sensitive pen works well.
I would like to send pull request to upstream with this tablet. But before that, I should know what those numbers mean, so I would appreciate your comment on that.
Thank you again, it was easier and more straightforward than I thought. |

So I found out that those numbers affect the size of the tablet that is reported by `libinput list-devices` command. So I changed those numbers so that the size reported is right. So now this is how the file looks - /etc/udev/hwdb.d/61-evdev-local.hwdb:
| Code: | #########################################
# UC-LOGIC
#########################################
# UC-LOGIC Tablet WP8060U
evdev:input:b0003v5543p0005*
EVDEV_ABS_00=::160
EVDEV_ABS_01=::219
