Thanks Christopher If I don't use the acpi_osi= kernel parameter in Lucid, the brightness hotkeys do not work. (see comment #21) Remark: all my comments and attached files until comment #21 are without acpi_osi= (except the "when adding the acpi_osi= [snip] any more." sentence in the bug description)
According to http://www.kernel.org/doc/Documentation/kernel- parameters.txt says acpi_osi= disables all strings in the "list of supported OS interface strings". Would it help if i indicate the content of this list? (if yes, where can i find this list?) I'll try to follow https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Overview_on_Reporting_Bugs_Upstream . -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1041116 Title: Brightness hotkeys have no effect on Clevo laptop To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1041116/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
