Hi Micheal, Since you are the original bug reporter, based on you most recent comment - https://bugs.edge.launchpad.net/ubuntu/+source/linux- source-2.6.22/+bug/173652/comments/132 - it would seem that the original issue of the brightness keys not even working is no longer an issue in the latest Jaunty Alpha. The granularity of the number of brigthness steps available would be more of a low to wishlist bug importance and I think should likely even warrant a new bug being opened. Would you agree? If so, lets go ahead and mark this one Fix Released for Jaunty and post a link to the new bug. It's much easier on the development teams if bug reports target one specific issue, otherwise they end up having to sift through 100+ comments before they even get to the new issue at hand.

On Jaunty with latest updates I now get 9 steps for the backlight with the Fn key combination. When I installed (Alpha 3) there were only 5 steps, so some update changed it. 9 steps (while an odd number) is working a lot better now, and much more usable because the difference between the steps is not so drastic.

To be honest, with the patch I'm using in stable, I get 20 steps. I find this just a slight tad to many. mostly because I feel it should have a little better flow. 19 to 20 goes from I'd like this a little darker to completely black.

I'm changing the status of this bug back to a "Triaged" state.

Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information.

I have a fairly recent model: Sony VGN-NR498E, Intel X3100. With a fresh install of 8.10, the function keys cause the backlight OSD to move up and down properly, however there is no adjustment to the backlight. If I use the command "xrandr --output LVDS --set BACKLIGHT_CONTROL native", I can immediately adjust brightness with the function keys. With native, I am subject to what I believe above is being called the oscillation bug. This setup is non-functional. Also, with native, if I click the power manager icon, the power manager doesn't respond. On the other hand, If i use the command "xrandr --output LVDS --set BACKLIGHT_CONTROL legacy", I have brightness control with the function keys, and I don't have the oscillation problem. Some other events do adjust brightness (and leave it that way) though, such as going to preferences of the power manager dims the display. With either BACKLIGHT_CONTROL setting, I don't have to use the xbacklight command at all, and I don't have xbacklight installed.

Vaio VGN FS840/W (915GM chipset) here, using the latest xserver-xorg- video-intel v2:2.4.1-1ubuntu10. I also have this problem with my backlight. After quite some time debugging the gnome brightness applet and gnome-power-manager, I realized gnome-power-manager is seemingly dependent upon xrandr. When running gnome-power-manager with --no-daemon and --verbose, I can see that it thinks the range for my brightness is (0,0). Xrandr also thinks the range is (0,0). If I change BACKLIGHT_CONTROL to legacy with xrandr, --prop will say my backlight range is (0,255), which is reflected in gnome-power-manager. Unfortunately, adjusting the BACKLIGHT with xrandr or the brightness applet does nothing (I have tried setting BACKLIGHT_CONTROL to native, kernel, legacy and combination with no results). When I run xbacklight, it returns "nan". If I write a value from 0 to 7 into /class/backlight/sony/brightness, my screen brightness will be adjusted. I understand this to be a function of the sony-laptop module however, not the video driver. The brightness applet doesn't use this method, so it is effectively broken. If I use the VESA driver, xrandr and the brightness applet work as expected. I assume this has to do with the intel video driver? -- Unable to adjust screen brightness on recent Sony Vaio notebooks, Intel GMA adapter https://bugs.launchpad.net/bugs/173652 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

I do feel this is redundant. BUT. I attached that info you wanted. I feel that script is rather bloated so instead ran the commands. I need xrandr. Once I do that, everything works except for the oscillation bug. This bug is filed and mentioned above. Once oscillation begins, I need to wait for it to hit a certain point before changing the brightness again. This tends to mean going to pretty much entirely non-visible first. There were some xorg updates today (I think today) that I haven't tested yet. - The script posted above by Brian Royer is not correct. ACPI does not need to be restarted. There is no need to zenity. As of this point in time, there is only one command that needs to be run to gain control over all systems that are being actively tested against. "xrandr --output LVDS --set BACKLIGHT_CONTROL native" Again, I feel this is redundant, but perhaps it will help people that skim this bug, which is getting large, looking for a quick fix or more information. ** Attachment added: "info" http://launchpadlibrarian.net/18890282/info -- Unable to adjust screen brightness on recent Sony Vaio notebooks, Intel GMA adapter https://bugs.launchpad.net/bugs/173652 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

Please concentrate on fixing correct way of backlight control instead of writing custom scripts.

I report on my model, using live CD downloaded today, hotkeys does work out of the box pretty nice. It does show backlight OSD, it does move the bar in correct way.

** Description changed: Fn keys don't work for dimming the screen, though they do stimulate the sonybright.sh script. xbacklight works if the notebook has an Intel 965 (x3100) display adapter, but is subject to bug #176888 (won't work on Hardy, bad XRandR setting). - There is no known method for setting the LED backlight on newer Vaios - with nVidia GeForce 8 series adapters, though it is possible to pseudo- - dim by making the LCD blacker (this unfortunately doesn't help with - power-saving). See bug #95444 + See bug #95444 for a hack to nvclock which makes it possible to control + backlight on nVidia 8 series adapters (SPEED mode on the SZ650). There are 2 problems here: 1) The Vaio's LED screen is really very bright when burning at 100% and is hard to look at for any period 2) Battery life suffers Pretty much all the newer Vaios (2007 onwards) have some combination of these graphics adapters so this bug should be widespread (and much appreciated when fixed!). A couple of script solutions have been proposed in this bug report; please feel free to hack and make suggestions. One solution for notebooks with Intel 965 display adapters is to install xbacklight: ]$ sudo apt-get install xbacklight Then add these 2 lines to /etc/rc.local (or just execute from the command line): xrandr --output LVDS --set BACKLIGHT_CONTROL native /etc/init.d/acpid restart And edit /etc/acpi/sonybright.sh so that is contains only this: #!/bin/bash if [ "x$1" = "xdown" ]; then xbacklight -time 100 -steps 10 -dec 10 2>/tmp/sonybright.log elif [ "x$1" = "xup" ]; then xbacklight -time 100 -steps 10 -inc 10 2>/tmp/sonybright.log else echo >&2 Unknown argument $1 fi Please note that this will not affect brightness on nVidia 8 series adapters, just Intel adapters.

[Bug 173652] Re: Unable to adjust screen brightness on recent Sony Vaio notebooks, Intel GMA adapter
There's a difference here too. I can use the Fn keys to change the brightness setting prior to running the xrandr command. Once I run it, I have no control over it. The xbacklight commands no longer work either. I guess we're somewhat back to it not working at all except that I still have the oscillation. -- Unable to adjust screen brightness on recent Sony Vaio notebooks, Intel GMA adapter https://bugs.launchpad.net/bugs/173652 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

Backlight behaviour in Hardy has changed slightly; now the backlight indicator (I guess from g-p-m) is shown on the screen in response to Fn- keys but the rest of the bug is unchanged: still need script, to run xrandr command and restart acpid. -- Unable to adjust screen brightness on recent Sony Vaio notebooks, Intel GMA adapter https://bugs.launchpad.net/bugs/173652 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

[Bug 173652] Re: Unable to adjust screen brightness on recent Sony Vaio notebooks, Intel GMA adapter
OH! Unfortunate! Apparently nobody ever sit on this xrandr fix. After changing the screen brightness to the desired level, I use the system. I'm completely active when doing so. Somehow the screen just starts fading to black. I haven't had this issue with the fix in 8.04.1 but it's showing up now. It seems like once this starts happening, I can't change the screen brightness easily. I hit the screen brightness up in reaction to the downward direction it's taking and it doesn't respond for a while. It takes 5-20 sec for it to react and change the brightness back up. It does seem to somewhat snap back up once it hits the point of listening to me though.

[Bug 173652] Re: Unable to adjust screen brightness on recent Sony Vaio notebooks, Intel GMA adapter
Just another confirm for working after running 'xrandr --output LVDS --set BACKLIGHT_CONTROL native'. I'm now running 8.10 so I'll scream with joy in here when it's working for me. One thing I am noticing though, is that the reaction time is pretty slow. When I press the Fn+F5/6 it takes almost a second to change. This keeps me from being able to quickly tap down the brightness next to bottom. One other thing I've been noticed (previous work arounds as well)... When turning the brightness all the way down, the screen goes from slightly visible (about the lowest I can use it) to pretty much entirely black. Either way - :D :D :D Side Note: Touchpad doesn't work quiet the same and has a very narrow right scroll. As well as I need to test out all the other hardware such as external monitor since it might work now. :D -- Unable to adjust screen brightness on recent Sony Vaio notebooks, Intel GMA adapter https://bugs.launchpad.net/bugs/173652 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
[Bug 173652] Re: Unable to adjust screen brightness on recent Sony Vaio notebooks, Intel GMA adapter
Hi,
on latest intrepid and vaio BZ11XN (X4500MHD) :
- sudo /etc/acpi/sonybright.sh {up|down} works, but only after "xrandr …
CONTROL=native"
- xbacklight works, with xrandr previously called too (but not without)
- Fn-keys produce nothing for LCD (but work for sound), and I attached my acpi
debug info to bug
https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/251665 but I think
it was missed because the bug is fixed for original poster and not for me,
though we had the same problem.

Wow, long bug. Hope I didn't miss something obvious. I have a Vaio VGN- CR120E with the " Integrated Graphics Chipset: Intel(R) 965GM" chip set and have always (since at least Hardy beta) been able to adjust the brightness with the following two command lines (although hotkeys have never worked): sudo /etc/acpi/sonybright.sh up sudo /etc/acpi/sonybright.sh down Not sure how I discovered this workaround for the keys, but in release Hardy someone tipped me off that I could use the panel gnome-brightness- applet which gave me an acceptable solution. Unfortunately that is now broken in Intrepid and I'm back to terminal to adjust my screen brightness :-( https://bugs.launchpad.net/ubuntu/+source/gnome-power- manager/+bug/243904 ).
