While I agree with Qole.. Most of us here that help with the Tablet are likely also familiar with linux - Especially debian.

I'll see if I can't provide some advice.

Your problem likely exists inside your xorg.conf file.. incorrect video card driver or possibly screen resolution/depths etc.

To help you with this we'd need a lot more info... namely: What is your Laptop/"Note Book"? Model number would be appreciated.. help us determine what video card/LCD screen your laptop is running.

Also attaching the /var/log/Xorg.0.log file might also help.. (don't copy/paste.. that's likely to be a lot of text.)

To address what Qole was saying.. This Forum is actually where a question like this should go. You want help with Debian, not the Tablet.
