As in you weren't able to get the settings back in or that worked but didn't help the problem?

I compiled with GPIO pins settings back, but this did not help.
The DC-DC converter is disabled in lcd-ssd1303.c. Does OF also disable the DC-DC converter?
Perhaps my clip OLED-Driver has to run with converter.

Yes the init routine is the same than the OF.
You can try enabling the as3514 dcdc like Fuze & e200:
--- Code: ---ascodec_write(AS3514_DCDC15, X); /* current = X * 1.25mA : ranges from 0 to 0x1f = 38.75mA */
--- End code ---

OLED Driver of my Clip is supplied by as3514 DCDC. Screen is now bright with code above and X = 0x10. Will test other values for X. Thanks for the tip.

Cool! Please post a patch to FlySpray when you have something clean.
Also note if it makes any lightning difference with different values.

i can confirm this as well. i also have european clip v1 without FM. i'm not much of a developer, especially with this low level coding, but i can help test patches :)
