linux and my Thinkpad R40
some words on installing/configuring debian on the IBM thinkpad R40. Note that this is not ment as a complete guide on how to install linux on the tp. To get much more information i recommend e.g. tuxmobil.org.
My R40 comes with:

  • 1.4GHz Pentium M
  • ATI Radeon Mobility 7500
  • 15" SVGA Display
  • 512 Mb RAM
  • DVD-CD/RW Combo




kernel
recently i switched from kernel 2.4.23 to kernel 2.6.8.1 from kernel.org. To get stuff like acpi, suspend-to-ram, suspend-to-disk (or hibernate) and fancy bootsplashes to work, i additionally used these three patches:




swsusp2 and acpi:
you only need one swsusp2 patch. (no additional "core"-patch). I had to unpack the patch and apply them in order, starting with the smaller numbers (20..., 21..., ...) otherwise i got lots of errors during patching.
the kernel configuration: 

	Power management options (ACPI, APM) --->
		Software Suspend 2 --->
			[ * ] Software Suspend 2
			[ * ] Swap Writer
			[ * ] LZF image compression
			[ * ] bootsplash support
			[ * ] Use ACPI S4 support
			[   ] Suspend-to-disk Support

note: I had to deactivate suspend-to-disk support (otherwise it did't compile)
and added to my lilo.conf:

	append="resume2=swap:/dev/hda3" (where hda3 is my swap partition)
now, suspend-to-disk works fine with the "hibernate" script from the swsusp2 website.(Sometimes i have problems with the ethernet-card after wake-up so i unload the e100 modul before hibernation)
suspend-to-ram (after rmodding all usb modules) also works fine with "echo -n 3 > /proc/acpi/sleep".
For the power-management i use cpufreqd.




bootsplash:
after patching the kernel, the kernel configuration goes: 

	Device Drivers --->
		Graphics support --->
			[ * ] Support for framebuffer devices
			[ * ] VGA 16-color graphics support
			[ * ] VESA VGA graphics support
			[ * ] ATI Radeon display suppor
			[ * ] DDC/I2C for ATI Radeon support
			 Console display graphics support --->
			[ * ] Video Mode selection support
			[ * ] Framebuffer Console support
		Logo configuration --->
			[  ] bootup Logo
		bootsplah configuration --->
			[ *] bootsplashscreen
		block devices --->
			[ * ] Initial RAM disk (initrd) support

this is my lilo.conf:

	image=/boot/vmlinuz-2.6.8.1-040921
	label=pitz
	root=patz
	vga=0x31A #1280x1024
	initrd=/boot/initrd.splash # or your initrd image or the one you selected during config
	append="resume2=swap:/dev/hda3 video=vesafb:ywrap,mtrr"
in the sources.list i use:
	deb http://www.bootsplash.de/files/debian unstable main
	deb-src http://www.bootsplash.de/files/debian unstable main
and installed the packages: bootsplash and some bootsplash-themes.
If the bootsplash doesn't have the native resolution of 1400x1050 the console looks crappy. To get the higher resolution 1400x1050 one has to change the resolution of the picture in /etc/bootsplash/themes/current to 1400x1050 and run "dpkg-reconfigure bootsplash". the lilo.conf has to be changed to:
	vga=0x342 #1400x1050
	append="resume2=swap:/dev/hda3 video=vesafb:1400x1050,ywrap,mtrr"

note: One also should create a bootsplash-1400x1050.cfg file in /etc/bootsplash/themes/current/config/ (i just copied/rename the 1280x1024 one)




mousepad and trackpoint
it's probably the best idea to install the synaptics drivers via the "xfree86-driver-synaptics" package. After installing it like written in the readme i realized, that the trackpoint and the 3 buttons above the touchpad did not work anymore. To get all five buttons to work i needed to install gpm.
This is my gpm.conf:

	device=/dev/psaux
	responsiveness=
	repeat_type=raw
	type=ps2
	append=''
	sample_rate=

in the XF86Config-4 i had to put in another input-device like:
Section "InputDevice"
	Identifier  "PS/2 Mouse
		Driver  "mouse"
		Option  "Protocol" "PS/2"
		Option  "ZAxisMapping" "4 5"
		Option  "Device" "/dev/gpmdata"
		Option  "Emulate3buttons" "true"
		Option  "Emulate3Timeout "70"
		Option  SendCoreEvents "true"
	EndSection

and under "Server Layout":
	InputDevice "Mouse[1]" "CorePointer"  (which is the touchpad)
	InputDevice "PS/2 Mouse" "AlwaysCore"

wireless
works with the ndiswrapper modul and the intel pro/wireless 2100 drivers here.
