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
