FIXED - sort of.
I just upgraded BIOS and kernel, and was still having trouble. I
discovered the following restores FN-Home/End functionality as long as
it's run _after_ X starts... No dice if I put it in /etc/rc.local, and I
can't change permission of a /proc file to let .xinitrc do it:
# Happy times are here until reboot!
sudo /etc/init.d/acpid restart
It looks like this has been around a while:

Just noticed a strange issue with kubuntu/8.04b1. brightness-up works as expected, but brightness-down seems to trigger multiple events, 4 in fact. The event popup indicator from 'power manager' appears to show it stepping through the skipped brightness levels, although it happens very quickly so it's difficult to be sure. -- [REGRESSION] Impossible to change LCD brightness on Thinkpad R61/T61/X61 https://bugs.launchpad.net/bugs/198476 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

Tried kernel 2.6.25-rc8 and brightness works! So there are fixes upstream. Also it's very quick too (unlike it being slow and sluggish). One thing is the thinkpad-acpi probably neededs to be moved up to 0.19.

I downloaded and upzipped the patch to the desktop, but I can't seem to copy it to the usr/src directory, something most of the online directions find say I need to do. How would I go about that?

It says and I quote .. When display backlight brightness controls are available through the standard ACPI interface, it is best to use it instead of this direct ThinkPad-specific interface. But right now they're not (available) and the thinkpad_acpi option is easy to implement, works in the meantime, and is easy to reverse once a real fix comes along. I'm glad I found this report.

So going through the kernel log at https://launchpad.net/ubuntu/+source/linux/ This appears to broke in 2.6.24-11.17 with one of the following entries that was pulled from upstream: * ACPI: video: Rationalise ACPI backlight implementation -- This is most likely the culprit * ACPI: video: Ignore ACPI video devices that aren't present in hardware This is currently broken in 2.6.25 (which I assume where these patches were pulled from). Now remember it works with 2.6.25-10.16. So what we know: - This effects only Thinkpads with Intel x3100 - This broke with 2.6.24-11.17 update - There is a really bad work around using thinkpad acpi ... please read kernel source/Documentation/thinkpa-acpi.txt It says and I quote .. When display backlight brightness controls are available through the standard ACPI interface, it is best to use it instead of this direct ThinkPad-specific interface. * So you should not be using backlight= thinkpad_acpi option * The problem is the ACPI interface is broken, so please stop mentioning it in this bug - Also even though you see the Gnome backlight indicator slowly going up and down, the actual backlight is not changing. -- [REGRESSION] Impossible to change LCD brightness on Thinkpad R61/T61/X61 https://bugs.launchpad.net/bugs/198476 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

Brightness works almost fine on my ThinkPad R61, but there are problems when level reaches 0, than another acpi event ( ibm/hotkey HKEY 0080 5010 ) occurs. Also there is a problem with brightness when system is booted with lower level and than in X or console changed, after switch it restores the previous low level. Also this happens with mplayer. Disabling brightness up/down (and using only video module for this) hotkeys didn't help.

I can confirm the regression in my Lenovo Thinkpad X61_s. Brightness buttons worked in Gutsy and stopped working in Hardy. However brightness buttons do work if I boot with Gutsy kernel (2.6.22-14-generic).

This appears to only effect thinkpads using the Intel x3100 graphics. I have a Thinkpad 61p with Nvidia Quadro and the brightness control works (updating today's packages), using the proprietary nvidia driver. But when I try my other Thinkpad T61 with Intel x3100 it does not work. Also using thinkpad acpi option is a bad work around for the real issue.

Seems I am the most fortunate, for me adding 'options thinkpad_acpi brightness_enable=1' to /etc/modprobe.d/options helped, it made brightness changing working and also the Gnome brightness indicator non laggy. For the record I have an R61-8935. The only glitch remaining is that Fn+End changes the brightness down in around twice as big steps as Fn+Home up, more precisely it requires 8 steps from 100% down to 0, and 15 steps from 0 to 100%. -- [REGRESSION] Impossible to change LCD brightness on Thinkpad R61/T61/X61 https://bugs.launchpad.net/bugs/198476 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
