Brightness problems

[Olivier M. <sh...@ss...>]

Hi,

I have several small brightness problems with my ~June 2005 12" iBook (cpuinfo
below)

The brightness adjust by itself works as intended, however,
 - when switching between (framebuffer) console and X, the brightness is always
set to the maximum (or minimum) value, and I have to press the britghtness keys
once to get it back to the previous level;
 - when suspending-to-ram the computer, then waking it up, its brightness is
once again set to max or min* and I have to press the brightness keys as above
to restore de last setting;
 - when closing the LID, which in my conf is blanking the screen, then
reoppening it, the screen stays black (no image) and, repeating once again the
above key magics, the screen shows up again (this happens with UseFBBlank=yes,
deactivating this feature solve _this_ problem. BTW what's the interest of using
this feature ?).

* max or min does not mean that it is randomly set to one or the other
brightness level. it seems to be dependent on the value of LCD_Brightness when
PBButtonsd has first been started after bootup, or maybe has it been just
changed from min to max with 0.7.4

I think my report is a little unclear, so just ask if information is missing.
