I got caught out on that once, and learned after that to pull the batteries out of the camera and let it run on mechanical when I wanted reliable flash operation. I wasn't using a TTL flash at the time, my Metz 60 CT-2 was capable of TTL, but it was so accurate on it's own that it wasn't necessary.
Fill flash was not the LX'x strongest suit.
Thanks for the tip I don't know about that on the LX, and I also find the Metz flashgun was very accurate even non TTL, I got the 45CT-3 without TTL and it worked great. Not only that, I compared the Metz with a Nissin flashgun with similar GN in manual mode, guess what, the Nissin was near a stop understand than claimed when measured with my Minolta flash meter at 1m/ISO100 with a grey card, where the Metz near 1 stop over that ! German did not cheat on the spec but quite messy at the electronics, if you open your Metz (be careful don't get electric shock !) you will see what I mean.
One thing I don't feel right about is that, in the 'old days' flashguns are rated at 35mm (wide angle in 35mm format), so that we can easily tell which one is stronger, but now most flashguns are rated at 50mm even longer, we can't cheat there is a limit in Physic. The power output of the flashguns governed by 2 things, one is the size of the capacitor the other is the volume (of gas) of the flash tube, even we can use ultracap that's smaller size, the flash tube can't be smaller, as far as I know studio strobe can do long duration flash as slow as 1/700sec, but I don't think hand flashgun can do longer that 1/1000sec.
