Dell XPS 13 9360 – Trackpad Issue

Several days ago the trackpad stopped working. It started when I connected a Apple Magic Mouse for more¬†convenient¬†playing. When I disconnected the mouse, I realized that the trackpad stopped working. Thinking the laptop just swallowed up I restarted the system. And sure enough, the trackpad worked again… for some hours. After that I just stopped working again. Sometimes it repeaired it self to the point that I could use it, but no multi touch gestures (pinch, scroll etc) would work. I had a look in the Hardware-Manager of Windows and saw a yellow exclamation mark next to a I2C HID-Device. The error message states “A request for the HID descriptor failed”, what ever that means.

Unfortunatelly there is no solution known to me. In the Dell forum two threads (one, two) describe my problem yet nothing seem to solve their issue. I’ll see the Dell support for this :-/

Solved: ImageJ / Fiji error: “IllegalArgumentException: adding a container to a container on a different GraphicsDevice”

For my master thesis I am experimenting with ImageJ / Fiji. While working with some image registration algorithms I happend to run in a strange bug I couldn’t explain to me:

Workaround / Fix:

If you happen to have this bug make sure all instances of ImageJ / Fiji windows are on the same monitor. This bug only occured to me when my Fiji toolbar window was on my main monitor and the plugin windows (Image Sequence loader and Linear Stack Allignment with SIFT) were on my secondary screen.

Reproduce:

If you want to reproduce this issue, use a system with the above mentioned spec (see stacktrace).

  1. Open Fiji on the main display
  2. Use “File / Import / Image Sequence…” to load at least two images
  3. Execute “Plugin / Registration / Linear Stack Allignment with SIFT” on the images
  4. When the registration is performed, move all Fiji windows but the Fiji toolbar to a second display
  5. Close all the Fiji windows but keep the Fiji toolbar open
  6. Repeat step 2) and 3)
  7. Exception gets thrown
