Hello Christopher,
This is no longer an issue for me though it may remain an issue for others
on the email list.
The combination of Kamal's kernel changes plus boot parameters plus making
sure gnome services were running (I run xfce) fixed the problem for me.
Thank you very much for looking

Hi all,
I think saghauer may be right, the screen brightness is probably not a
graphics card issue, as it is just the setting of the brightness of the
backlight. Still, under /proc/acpi, the brightness is listed under vga.
In particular:
cat /proc/acpi/video/VGA/LCDD/brightness
levels: 5 11 17
I can confirm that ubuntu probably has a problem with intel graphics,
and that in particular the brightness setting is one of the symptoms.
When I ran karmic, the graphics worked fine, including brightness
adjustment (with applet and with function keys).
Yesterday (Saturday June 12) I upgraded
David,
If you're considering a re-install, it might be wiser to re-install to
Karmic to restore brightness adjustment functionality. The brightness
issue isn't related to whether it's a fresh install of Lucid or upgrade
to Lucid, it is due to Lucid itself.
I've considered downgrading to Karmic
If I knew more about this stuff I'd be happy to hack a solution.
Unfortunately I do not. ConsequenltyI must rely on the mercy of our
community. Please help.
