Hibernate, Thinkpad light works ok. Do you have 'tpb' (ThinkPad Buttons) installed? apt-cache show tpb I think that this is what you are looking for. It both enables the function of the special keys and uses the on screen display (through libxosd2) to display the action. For me this was the secret sauce to make things work nicely. The installation of the package installs a script in /etc/X11/Xsession.d/90tpb that will automatically start the tpb process when you log into the X11 graphics session. But when you install it while running X11 then it won't get a chance to start yet because you already started it. Plus you need to be in the nvram group at that time too so that the program can access the nvram controls. These two things mean that typically you will need to log out and then log back in again as part of the installation process. Here is the process (I think, this is from my memory and I may have missed a step): 1. sudo apt-get install tpb 2. Read the /usr/share/doc/tpb/README.Debian, it is short, and understand the issues it describes concerning the nvram group. 3. editor /etc/default/tpb ... START_TPB="true" ... ... This may have already been presented as a debconf question at installation time. But it seems like I always miss it. ... ... This will start tpb automatically when next you log in. ... 4. id | grep nvram ... no output means no nvram group listed ... ... observe that you need to be added to the nvram group ... 5. sudo addgroup $(whoami) nvram ... nvram group will now be there upon the next login ... 6. Log out. 7. Log in. 8. id | grep nvram ... observe that you are now in the nvram group ... 9. ps -ef | grep tpb ... observe "/usr/bin/tpb -d" running ... 10. Test the buttons. Enjoy! If you decide you wanted to undo all of this completely then the following steps remove it and purge the configuration files from their locations in /etc/. (Purging the /etc/ configuration of packages means that if you install it again that it will install into a fresh, pristine and unedited state. Otherwise the configuration files would remain behind from the previous installation and would still contain their previous settings. Sometimes you want one and sometimes you want the other.) 1. sudo delgroup $(whoami) nvram 2. sudo apt-get remove --purge tpb 3. Log out. 4. Log in. Additionally I set "MIXER on" in my ~/.tpbrc file. This allowed me to intersperse changing the volume with the buttons and changing the volume with other programs such as the gnome panel volume control or the standalone 'aumix' and 'alsamixer' programs. You may or may not want that too. Try it first without it and try mixing up the control and see if you need it before enabling this configuration. > In Xubuntu 8.10 the keys all work without any post install config > needed.

Ubuntu has put a lot of effort into making the installer do a lot of these types of things automatically. This is good for casual desktop users because most of the time it works the way they want it to work without extra steps. But sometimes this type of automatic decision making also gets in the way. Sometimes it guesses too agressively. Then people need to take action to remove and deconfigure things. Sometimes the code to do this gets to be a burden upon the maintainers because it can basically turn into a huge lookup table of systems and types. As years go buy it can become a burden on the maintainers to keep the understanding of how the hacks works when making additional hacks. Having the maintainers gather experience with both ways of creating system installers is a good thing in the long run and will produce a better installer over time. But for the moment there are some things that need to be helped out after install for particular special pieces of hardware. The ThinkPad buttons is one of those that is special and different from say the Toshiba buttons or other models. Here are some good resources for ThinkPads. Note that you probably should read articles for the entire T-series in addition to your T61. http://wiki.debian.org/InstallingDebianOn/Thinkpad http://www.thinkwiki.org/wiki/Installing_Debian_Lenny_on_a_ThinkPad_T61 http://www.thinkwiki.org/wiki/Category:T_Series Hope this helps, Bob P.S. Note that in Sarge and Etch the kernel module 'ibm-acpi' was needed to be loaded, usually by addition to /etc/modules. But in Lenny's Linux kernel this was renamed to 'thinkpad-acpi' and is now automaticaly loaded in Lenny therefore nothing manual needs to be done.
