I have a problem with my Intuos 4 on Arch Linux. The tablet is working very well but the small oled screens don't show any information. The express keys work normally. For example, one of the keys send keystroke Ctrl+Z but the screen next to it does not show the text 'Ctrl+Z' as it should. The screens worked normally earlier this year but I'm not sure when the bug emerged. I have also tested the tablet with Windows and the screens work normally. I hope someone knows what might cause this.

    I don't believe anything in our driver has changed which would cause this, but to make sure you can try using the i4oled utility in the AUR [1]. After installing the package, run the following commands and verify that the word "Test" appears next to the first button.

    sudo bash -c 'echo 127 > /sys/bus/usb/drivers/wacom//wacom_led/buttons_luminance'
    sudo i4oled -t "Test" --device /sys/bus/usb/drivers/wacom/
    /wacom_led/button0_rawimg

    GNOME is responsible for setting the OLED text to match the button mapping, and I suspect something has broken on their end. If the test above works, please let us know and file a bug on their tracker [2].

    Looks like Sourceforge ate my commands... Attempt 2:

    sudo bash -c 'echo 127 > /sys/bus/usb/drivers/wacom/*/wacom_led/buttons_luminance'
    sudo i4oled -t "Test" --device /sys/bus/usb/drivers/wacom/*/wacom_led/button0_rawimg

      Quoting Jason Gerecke comp_nerd@users.sf.net:

      Looks like Sourceforge ate my commands... Attempt 2:
      sudo bash -c 'echo 127 >
      /sys/bus/usb/drivers/wacom//wacom_led/buttons_luminance'sudo i4oled -t
      "Test" --device /sys/bus/usb/drivers/wacom/
      /wacom_led/button0_rawimg


      There is also another tool [1] that works on gnome level. If gnome is
      broken that won't work, but i4oled should work as long as the kernel part
      is OK.

      I tried the test and it worked. It seems the problem is with GNOME. I already thought it's either the driver or GNOME but didn't know how to check it. Thank you for your help! I'll file the bug on GNOME bug tracker.
