Talk:Install Ubuntu 9.04 (Jaunty Jackalope) on a ThinkPad T400
For the "Here is a Step by Step guidance How to protect the harddisk through APS with Kernel 2.6.28!" section.
I have a T400 with Jaunty 2.6.28-11-server kernel. For me in the /etc/modprobe.d/local.conf the thinkpad_ec force_io=1 option didn't work. After removing it everything worked fine.
I made some changes to how grub's menu.lst file should be edited. This is the preferred way, as it is how grub generates the menu entries, and takes care of the "problem" of having to redo it each time there is a kernel update. --Mrthefter 18:29, 29 May 2009 (UTC)
"Before Installation" - Section
Actually the before installation section is outdated, since Ubuntu 9.04 (the final release) is able to boot on a T400 WITHOUT disabeling switchable graphics in BIOS!
But after installing fglrx the system will not boot until the driver is removed. (So, it looks as if you have to choose between fumbling with BIOS or not using ATI graphics)
Mouse Wheel Emulation
For me the mouse wheel emulation did only work after wrapping the xml file in <deviceinfo version="0.2">...</deviceinfo>. This seems to be the correct way of doing it, but I know practically nothing about hal. -- caramdir 16:01, 1 May 2009 (UTC)
For me it only worked after deleting /var/cache/hald/fdi-cache (also the touchpad on/off button (fn+F8)). Maybe this could be included in the script? I'm using a Thinkpad T400 with Kubuntu 9.04 (KDE 4.2). -- yan, 1 June 2009 (UTC)
I'm fuzzy on what laptop mode parameters do, so I'm leaving this suggested edit to somebody that knows what they're talking about. The phrase "change 'BATT_HD_POWERMGMT=1' ... to an higher value to stop permanent harddrive-parking!" doesn't make sense to me. Isn't parking something we want, instead of permanently stopping it? I think the setting of 1 causes parking to happen too often or prematurely, but not permanently, though it may seem to be permanently parked with this setting. A setting of 200 should cause parking to occur less often, right? I think the word "permanent" should be changed to premature or frequent. Yes?

Look in the hdparm manpage the description of the -B option. And yes, the use of the 'permanent' word is utterly wrong.
