I just noticed Acer made available a bios-update that fixes the issue of controlling the backlight when using KMS on the timeline 5810T.

Changing status back to confirmed. Thanks for the post/comment, trendzetter. The last time I checked it, it was there, now it isn't... The weird thing is, that the backlight control actually works as expected (using quick keys), for me, without xrandr --prop showing anything... ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Fix Released = Confirmed -- xrandr backlight property control missing (when using KMS?) https://bugs.launchpad.net/bugs/428054 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

Cheers for the hint, executorvs! However, that doesn't work. The options I have for xrandr BACKLIGHT_CONTROL are native, legacy, combination and kernel, and none of them makes any difference. The only difference to my comment #2 is that now I can see and select different backlight control methods.

I'm closing this bug, since now the BACKLIGHT_CONTROL property is visible and usable. Not still being able to adjust the backlight is a different issue, and there exists many bug reports, as mentioned in comment #4. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Confirmed = Fix Released -- xrandr backlight property control missing (when using KMS?) https://bugs.launchpad.net/bugs/428054 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

The backlight property only shows up when using nomodeset.

trendzetter, that workaround does not work for me. And, the recent kernel update, with backlight fix on Intel driver, didn't help neither.

Matti, while not a perfect solution the command xrandr --output LVDS --set BACKLIGHT_CONTROL native will make screen brightness work (if not perfectly) when entered. it is not persistent and needs to be reentered on boot either manually or by setting it as a startup process. -- xrandr backlight property control missing (when using KMS?) https://bugs.launchpad.net/bugs/428054 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

Confirming on Acer Aspire 2920 w/ Intel 965GM, Karmic up-to-date. When using Fn-Left or Fn-Right to adjust brightness, the bar on the screen moves, but display does not change. *). Running xorg --prop is missing backlight control. However: m...@acer:/proc/acpi/video/GFX0$ cat DD0[1-5]/brightness not supported not supported levels: 10 20 30 40 50 60 70 80 90 100 current: 60 not supported not supported So, DD01, DD02, DD04 and DD05 claim not to support backlight, but DD03 does. *) The brightness DOES change, when trying to reduce brightness when /proc/acpi/video/GFX03/brightness is already at minimum (10), or when trying to increase brightness when the bar it's at maximum (100).

Seems to me that this might be a mayor issue. I don't know how many people are affected but many people are buying notebooks with these intel graphic chips.
