For the record, do not boot a debug kernel on laptop with the power plugged into it. The laptop is unusable. So anyway, I tried this keyboard on tumbleweed and had the same issue. So I've come to the conclusion that the problem is with the range of bluetooth signal the keyboard is capable of. It's not that good unless you are very close to the laptop which kind of defeats the purpose of having a separate keyboard. We can close this.

I'm currently leap 43. If this fix makes in the next leap kernel, I'll retest. -- You are receiving this mail because: You are on the CC list for the bug.

Confirmed. Have been using the Anker kbd for 2 days now. I'm about 3.5-4 feet away and it doesn't disconnect like it used... Awesome. Thanks Jiri. -- You are receiving this mail because: You are on the CC list for the bug.
