[Bug 367309] Re: [i945GM] xrandr backlight control is bizarre on Macbook
I've deleted the references to the brightness-button problems I could
not reproduce in Karmic.
** Description changed:
Binary package hint: xserver-xorg-video-intel
- I'm using Jaunty on a second-generation Macbook ("Macbook2,1" in Apple
- parlance) with an Intel 945GM graphics chip. Since at least Intrepid,
- I've had a strange and puzzling behaviour with the backlight keys.
- Tonight I tried upgrading to version 2.7 of the Intel driver from the
- x-updates PPA in the vain hope it might resolve the issue, but since it
- didn't I sat down and took a good hard look at the problem.
+ I'm currently using Jaunty on a second-generation Macbook ("Macbook2,1"
+ in Apple parlance) with an Intel 945GM graphics chip, and have
+ reproduced this issue on Karmic Alpha 2.
I tried switching to each of the available BACKLIGHT_CONTROL methods
with "xrandr --output LVDS --set BACKLIGHT_CONTROL $method", then
checked the available range with "xrandr --prop" and tried a selection
of brightness settings with "xrandr --output LVDS --set BACKLIGHT
$value"
When I run "xrandr --prop" the default BACKLIGHT_CONTROL value is
"native", whose range of backlight values is the unusual range 0..296.
These numbers map to brightnesses as follows:
- Even numbers from 0 to 40 turn off the backlight.
- Even numbers from 42 to 296 uniformly increase the brightness to full
strength.
- Odd numbers from 1 to 253 uniformly decrease the brightness from full to
very dim.
- Odd numbers greater than or equal to 255 turn off the backlight.
The end result is that trying to change the brightness with F1 and F2
involves mashing one or the other until you get a brightness level
you're willing to put up with and hope that nothing changes it.
The "legacy" BACKLIGHT_CONTROL method has a range of 0..255, where every
value produces the same mid-level brightness.
The "combination" BACKLIGHT_CONTROL has a range of 0..148, half the range of
the "native" method, and it behaves like half the "native" method too:
- Numbers from 0 to 20 turn off the backlight.
- Numbers from 21 to 148 uniformly increase the brightness from very dim to
full strength.
The "kernel" BACKLIGHT_CONTROL has a range of 0..0. Setting the
backlight value to '0' produces no obvious effect (if the backlight was
on, it stays on; if the backlight was off it stays off)
- A side note: when I first play with the keyboard brightness buttons,
- they followed the chaotic behaviour of the default, "native"
- BACKLIGHT_CONTROL above. Now that I've been messing with the
- BACKLIGHT_CONTROL value, the brightness buttons control a smooth
- gradient from 'very dim' to 'full strength' regardless of the
- BACKLIGHT_CONTROL, although I can't actually turn the backlight off with
- the keys. I'll ascribe that to some GNOME feature being clever, and
- ignore it until the underlying xrandr feature is fixed.
-
I would be happy if the Intel driver defaulted to "combination"
BACKLIGHT_CONTROL on my hardware, since at least that works in a
predictable and useful fashion. However, certain patterns make me
suspect there's some underlying problem to be fixed - like the fact that
the total 'lit' range in 'combination' mode is 127 brightness levels,
which seems a far more likely range than 148.

[Bug 367309] Re: [i945GM] xrandr backlight control is bizarre on Macbook
I burned the Karmic Koala Alpha 2 64-bit desktop image to a CD-RW, booted off it, and tried reproducing the problem using the steps in comment 0: - Brightness keys on the keyboard can now turn the backlight off, which was not previously possible. - Brightness keys now navigate a reasonably smooth gradient from full-bright to off. - xrandr's BACKLIGHT_CONTROL still defaults to 'native' - xrandr's BACKLIGHT property, under 'native' control, still exhibits all the strange odd/even behaviour mentioned in the original comment. I would say this bug has become less urgent, since my brightness keys now work properly without intervention, but the underlying problem is still present. ** Attachment added: "Xorg log, as requested." http://launchpadlibrarian.net/28483060/bug-367309-Xorg.0.log -- [i945GM] xrandr backlight control is bizarre on Macbook https://bugs.launchpad.net/bugs/367309 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
