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.

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...

2a. When pressing Fn-Pos1 (brightness up), /var/log/messages shows Sep 23 13:57:54 linux powersaved[3610]: WARNING (continueEvent:248) Could not execute program /usr/lib/powersave/scripts for event other: No such file or directory

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?

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. Hopefully this info is helpful. ~Loki -- 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.

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.
