OK, here's what I've done to workaround the problem on my Thinkpad T30 until it's correctly fixed:
$ sudoedit /usr/share/hal/fdi/policy/10osvendor/10-laptop-panel-mgmt- policy.fdi I then added this stanza near the bottom: <device> <match key="info.category" string="laptop_panel"> <match key="/org/freedesktop/Hal/devices/computer:smbios.system.manufacturer" string="IBM"> <match key="/org/freedesktop/Hal/devices/computer:smbios.system.product" contains="2366"> <merge key="laptop_panel.brightness_in_hardware" type="bool">true</merge> </match> </match> </match> </device> Note that my smbios.system.project was optained from my product number from lshal (236697U). Then I did $ sudo invokerc.d dbus restart gnome-power-manager crashed, so I restarted it, and now the brightness buttons work and the brightness policy from g-p-m works, too. The only problem that remains is that the brightness popup (the box with the sun icon and meter) always stays zeroed regardless of how high I turn up the brightness. -- [Feisty] Thinkpad (all models) LCD brightness control cycles between lowest settings only https://launchpad.net/bugs/81407 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
