Seth, I booted into your kernel at http://people.canonical.com/~sforshee/lp1098216/linux-3.8.0-19.29~lp1098216v201304221819/ on my T530.
It's definitely mixed results: + brightness keys on keyboard work again, and I get the full brightness range - shift+brightness keys don't step through the very fine brightness levels that I recall from 12.04 and 12.10. These are just coarse jumps. - The on-screen-indicator is completely wrong. Probably not unexpected. - Settings | Brightness slider does nothing. Probably not unexpected. Adding acpi_osi='!Windows 2012' works better: + brightness keys work, I get the full brightness range + shift+brightness keys step through very fine brightness levels + on-screen indicator works with coarse stepping; doesn't work with fine stepping + Settings | Brightness slider works Thanks again -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1098216 Title: Regression in brightness control on Lenovo Thinkpad X230 and X1 Carbon To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1098216/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
