Key ghosting / rollover: Why on the built-on keyboard the combination of mousedown-left+mousedown-down actions don't together, but on mechanical keyboard (Keychron k2 v2) it works together so I can move mouse diagonally.

I assume that it is because the built-in keyboard of the thinkpad is not mechanical, but membrane. Correct me if I'm wrong. Why mousedown-left+mousedown-down actions don't work together?

Indeed this sounds like a key ghosting problem.

How can I solve this?

You can't solve it, it's a hardware design flaw (intentional, to save cost).

Your workarounds are:

• don't use the bad key combinations
• use a different keyboard
