[Ubuntu-x-swat] [Bug 557635] Re: Intel GMA X4500HD - LCD Brightness Control no longer works
** Description changed: Binary package hint: xorg This is on an Asus K50IJ laptop with Intel GMA X4500HD graphics. In the previous release (Karmic), the LCD brightness adjustment both on the keyboard, as well as the auto-dim for power save, worked flawlessly. As of today (April 7th, 2010) with all updates run, this still does not function for me in Lucid. The hotkey press does invoke the onscreen display that shows that an adjustment should be taking place, although it has a definite delay for subsequent presses. The actual screen brightness, however, does not change. Needless to say, this also effects battery life. In Karmic, I was able to run about 3 hours on battery, now I can get right at about 2 hours, presumably due to the extra battery consumption necessary to run the screen without being able to reduce brightness. The output of lshw is attached, hope this helps.

This seems to be the problem: %lshal -l -u /org/freedesktop/Hal/devices/computer_backlight udi = '/org/freedesktop/Hal/devices/computer_backlight' [..] laptop_panel.brightness_in_hardware = true (bool) Thus PowerDevil/Solid only register the brightness key presses but don't actually set the brightness as they expect the hardware to do this. Can others with this problem confirm that this is the same issue for them or do I have a different bug and should open a new report? -- Intel GMA X4500HD - LCD Brightness Control no longer works https://bugs.launchpad.net/bugs/557635 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Store the attached file to /etc/hal/fdi/information and your Samsung NC10's brightness keys work again.

Same problem here on an Asus P50IJ. Once I press the backlight function keys I am also unable to use any of the other function keys like volume as well. Its as if it causes the whole system that deals with the fn keys/notification to lock up or slow way down. Adjusting the slider in the volume control applet still works however. Also the Brightness Applet does not work either. It will open but when the slider is clicked it just disappears. -- Intel GMA X4500HD - LCD Brightness Control no longer works https://bugs.launchpad.net/bugs/557635 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 557635] Re: Intel GMA X4500HD - LCD Brightness Control no longer works
Just tried using xbacklight on the command line. It is not able to adjust the brightness onscreen either, although it seems to think it is doing so. If i use the command to set the brightness percentage, then run xbacklight -get , it reports the percentage that I just set it to, although the actual screen brightness does not change. -- Intel GMA X4500HD - LCD Brightness Control no longer works https://bugs.launchpad.net/bugs/557635 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
[Ubuntu-x-swat] [Bug 557635] Re: Intel GMA X4500HD - LCD Brightness Control no longer works
Are there any developments on this bug? Just curious if this will be allowed in the final, which is only a couple days away. Just seems like a big regression to me since it worked in Karmic. Mind you, I know nothing about writing drivers or kernel code, but I just don't see how something that worked in a previous release is now broken.

[Ubuntu-x-swat] [Bug 557635] Re: Intel GMA X4500HD - LCD Brightness Control no longer works
Following behavior for me: - Brightness keys show the OSD but don't change anything. - Adjusting the slider in KDE4's battery applet does change the brightness - changing the power profile in the battery applet also changes the brightness (as would be expected from the point above) - volume keys work regardless of the use of the brightness keys both keys do emit X11 keycodes, i.e. xev shows XF86MonBrightnessDown/-Up and XF86AudioLowerVolume/...
