@Stefan I have tested your kernel, and everything seems to work again. Thank you. I don't have to specify "acpi_backlight=vendor". It works like it was the 2.6.27-10 kernel.
Have you reverted everything related to brightness, back to the state of 2.6.27-10? -- The slider brightness Applet has value inverted after the last update (2.6.27-11) https://bugs.launchpad.net/bugs/311716 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
