Re: [ibm-acpi-devel] Mute button software notification broken after v0.14 for Thinkpad T61
I heard that the X61 firmeware was actually behind that of the T series. Possibly the x61 will inherit all the changes that the T series now has when it gets it's next firmware update. Thanks for pointing this out though. Until Lenovo releases the next x61 firmware .. this will be a very interesting situation to deal with. Perhaps the adding the kernel paramater as Hernrique had said will probably be the short term solution for T series, till all this gets worked out over time.

running Kernel 2.6.24-rc7 (with thinkpad-acpi v0.19) with paramaters: acpi_osi=Linux -- Mute button Works! Gnome sees it is pressed. acpi_osi=!Linux -- Mute button NOT seen by Gnome.

Re: [ibm-acpi-devel] Mute button software notification broken after v0.14 for Thinkpad T61
For anyone keeping up with this thread. Also just to add on it's not a specific KDE or Gnome thing as both display the issue when running on kernels greater then 2.6.22 . They are not picking up the mute key press. On Jan 9, 2008 8:49 PM, Jerone Young [EMAIL PROTECTED] wrote: Ok it appears you are correct.

Very odd that the same firmware can do something fine on one kernel and not work on others. Thanks for the help and quick willingness to look into the problem.
