What happens?: 1) no brightness changes in hardware on Fn-Home/-End 2) * watch -n 0.1 'cat /sys/class/backlight/thinkpad_screen/actual_brightness' * if you press Fn-End you get this sequence: 7,6,5,4,3,2,1,0,7,...,0 3) if the backlight is on maximum (actual_brightness == 7) and you echo e.g. 6 to the sysfs attribute (brightness) the brightness get set down, but if you echo 7 again back you don't get the old maximum brightness back. If you unload the module, reload thinkpad_acpi and echo 7 to sysfs attribute you get the maximum brightness set, but the keys don't work. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Danny: if those laptops don't change the brightness level in hardware, would that mean our fdi patch in hal could cause this behaviour?
No, because use the keys lead to change the actual_brightness sysfs attribute also if HAL/KPowersave/Powersave are not running.

Let me describe the problem: The ThinkPad Module specific solution does not work anymore for T60/T61 and similar (R6X/Z6X/...), the solution for T60 family (which we added) is a very ugly workaround that should not exist. The Hardware is poked directly instead making use of the specified functions and the amount of brightness levels is hardcoded to 7 (but there are e.g. 15 levels for T61), this all is a mess. There is a Modul (video driver) which supports all this as defined by spec. T60/T61 also supports this (one has reported the video Modul working, it did not for Andreas, maybe it does if thinkpad module has not written on the HW directly). But we cannot make use of this as the brightness control between both driver would interfere and we need the ThinkPad Modul for docking and the bay. If this is not critical, I like to close this won't fix at the moment. People will start on fixing up video Modul pretty soon I expect as this seem to be used in Vista, but it's definitely too late for 10.3. -> Closing for now. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

On my T60 (model 2007-fug) brightness control also ceased to work after upgrade to beta3 and still didn't work in rc1. Two issues 1. tpctl, tpctl-kmp and tpb were missing; after install and reboot brightness control works now.
This mustn't be needed. I even wonder why we still ship those tools. I remember Seife somewhen talked about some very old models where this is needed. Maybe he knows more...

This error message is somehow misleading and smells like a update issue. I suspect a value in /etc/powersave/events:EVENT_OTHER that became superfluous with 10.3. It's already filed as bug 304976. Nevertheless, can you please post the value of that configuration variable?

But we shouldn't overreact now. For 10.3 GM it is too late. This does not affect major machine functionality, the user is still able to use the machine smoothly. I try to come up with a Lenovo ThinkPad only solution making use of the video extension ACPI spec functions. Not sure yet whether everything will work out as expected, but as they update their BIOSes because Vista is using those, this is the only sane way to provide a stable brightness support also for future. I come back as soon as I have something. As much Lenovo ThinkPads as possible should be tested then. Fortunately the patch will only get active on Lenovo ThinkPads, therefore I think the risk of breaking a machine is low enough with some testing of different ThinkPads. -> Fingers crossing is appreciated :) -> Still assigned to Alexey -> will take over.

For me, Fn+Home/End always works for changing the brightness, but thinkpad_acpi, and consequently kpowersave, etc have problems with it. After installation kpowersave claimed controlling brightness was not supported for my hardware, and indeed the /proc/acpi/ibm/brightness and /sys/class/backlight/thinkpad_screen interfaces were missing. grep thinkpad_acpi /var/log/boot.msg produced: <6>thinkpad_acpi: ThinkPad ACPI Extras v0.14 <6>thinkpad_acpi: http://ibm-acpi.sf.net/ <6>thinkpad_acpi: ThinkPad BIOS 75ET35WW (1.06 ), EC 75HT18WW-1.00 <6>thinkpad_acpi: IBM ThinkPad X41 Tablet <3>thinkpad_acpi: CMOS NVRAM (5) and EC (0) do not agree on display brightness level It seems that Fn+Home/End use the NVRAM interface, and this works even in the BIOS before the OS is loaded. If you make a note of the EC setting, reboot, and before the OS loads, use Fn+Home/End to make the NVRAM setting match the EC setting, then the thinkpad_acpi module will load without errors. You can also use Fn+Home/End to change the brightness to the same level as the EC on a running system, and then reinsert the thinkpad_acpi module. After this the /sys and /proc interfaces will be there, and everything works fine until you use Fn+Home/End to change the brightness. As soon as you do, cat /proc/acpi/ibm/brightness returns: level: unreadable cat /sys/class/backlight/thinkpad_screen/actual_brightness returns: -5 If you use Fn+Home/End to change it the brightness back, then you can use the /proc and /sys interfaces again, and everything works normally. Using the /proc and /sys interfaces to control the brightness properly updates both the NVRAM and EC, but Fn+Home/End only update the NVRAM.

But: killing gnome-power-manager does *not* help in my case. I notice there are (at least) 3 indicators of brightness: /sys/class/backlight/thinkpad_screen/brightness /sys/class/backlight/thinkpad_screen/actual_brightness /proc/acpi/ibm/brightness The second and third are cycled through 0 to 7 twice when pressing <Fn>+<Home>/<End> (and the OSD also cyles), but only when the brightness applet is used, the first changes (along with the other two) and only then the actual brightness changes.

Lenovo changed the mechansim twice on latest XY60 and XY61 models.
From 7 to 15 brightness levels and from Lenovo specific to ACPI specified brightness behaviour. This is not only model, but also BIOS dependent.
It would be great if you install latest 11.0 release into a small, free partition... There it's worth to provide Henrique (thinkpad driver maintainer) with as much info as possible and pre-debug this with a novell bugzilla entry. Henrique is doing backports of his latest code to several older kernel versions. I could integrate his backports..., but IMO too much work has been done here and there is risk to break other (especially older machines). For now I backported the latest thinkpad_acpi driver version to our 2.6.22 kernel and you can fetch a kernel from here (i386/x86_64) ftp.suse.com/pub/people/trenn/latest_thinkpad_driver_10_3_kernel Please try it out (as much people as possible). If reports are possitive, I will attach the patch here. I will still add some people for review and discussion whether it makes sense to add such a huge thing to the 10.3 kernel then. As said, please also give 11.0 a test in time. In Beta phase it is still easy to add fixes, as soon as the product is released, it's not. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Problem description: The brightness keys (Fn+Home/End) do not work properly. An OSD pops up but behaves strangely: As the progress bar proceeds, the brightness of the display stays the same, but once the max is reached, pressing Fn+Home repeatedly starts an oscillating behaviour: The OSD bar jumps between 50% and 100% and so does the brightness. Similar phenomenon for Fn+End - bar oscillating between 0% and 50%. The gnome brightness panel applet is working correctly though! Previously, in 10.3, this oscillating behaviour did not happen. But the bar ran from 0% to 100% twice - starting over at 0% once 100% was reached the first time. This seems to be related to the fact that the thinkpad acpi seems to have 15 brightness steps instead of 7. (Previously, in 10.3, the brightness applet only provided 7 steps, now this seems to have been fixed: the brightness applet provides all 15 steps.) nirvana:~ # cat /sys/class/backlight/acpi_video1/brightness 15 nirvana:~ here is something strange: nirvana:~ # cat /proc/acpi/video/VID1/LCD0/brightness levels: 100 100 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 100 current: 100 nirvana:~ # the brightness apple walks all steps from 20 (0) to 100 (15). the Fn-Keys oscillate between 20(0) and 55(7) at the low end and between 55(0) and 100(15) at the high end.
