Gentoo and an IBM T60p - Part 1: Installation and X
Got a new T60 yay!, here's my brain dump on getting it to work with gentoo (2006.1).

I followed the general install instructions for gentoo; no rocket science here. I used 2006.1/desktop profile, which sets a lot of handy use flags for you – what you have to do is unset those you don't want (like gnome or kde). In general, I try to keep the global flags list short(er) – though the default desktop profile pulls a lot of stuff in. I prefer setting use flags per package via the /etc/portage/package.use file.

euse (from gentoolkit) is very useful here. Using
euse -i you can tell: a) all of the packages that make use of a given flag and what they use it for, and b) whether or not it's included or excluded from the default profile or from your make.conf. Handy stuff.
I adjusted the grub install for Dual-boot, and did some checking for kernel options: a) ACPI configuration, b) removing DRM because of the ATI chipset (below), etc.
Just for the hell of it, I set up sSMTP to route to my gmail account4.
- kernel .config
I decided to add drivers for the touchpad (we'll see how long it lasts – I'll probably end up disabling it via the BIOS..) and for using the mouse on(in? at?) the console. I didn't need to do anything special aside from emerging the packages (and in the case of gpm, starting the daemon via /etc/init.d/gpm).
On-Screen Display and Thinkpad things
For thinkpad buttons, I use
tpb with the
xosd use flag to enable on-screen display when you push things (like the volume buttons). After emerging tpb, update
/etc/tpbrc per your preferences. Use the
hdaps useflag with
tm_smapi to enable 1/2 of automatic HD head parking function (the reading-the-data part).
For on-screen display to work w/ X, you have to start tpb when you start X, and it has to have access to the display, etc.
- script for starting tpb
Setting up X
This is the fun part. As noted above, the T60 uses an ATI FireGL graphics chipset, which means binary ATI drivers5. I grabbed the latest of both
~x86 for both in /etc/portage/package.keywords). The combination of use flags mentioned above were sufficient for both packages.
ati-drivers-extra-8.30.3 required libXinerama when the qt use flag is enabled, even if qt did not use that flag. I had to emerge
ati-drivers-extra to compile properly.
After emerging the package (followed by
source /etc/profile to regen path strings), I copied the
/etc/X11) and used
aticonfig --initial --input=/etc/X11/xorg.conf to create an initial xorg.conf file. Then I updated the file to strip down what was in there – keeping the ATI stuff, and punting the extra stuff.
Without too much fooling around, X came up (with DRI and everything). The settings generated by aticonfig left a lot to X11 defaults. 1600×1200 at depth 24:
# xdpyinfo | grep resolution -A 1 -B 1 dimensions: 1600x1200 pixels (301x221 millimeters) resolution: 135x138 dots per inch depths (7): 24, 1, 4, 8, 15, 16, 32
Now, I did check out
sys-apps/ddcxinfo-knoppix, and I have to say it's pretty neat. It spat out all kinds of things about the TFT display. I've included the output in the list below.
- ddcxinfo-knoppix for T60p TFT display, ddcxinfo-knoppix monitor section
I did see the following message in Xorg.0.log:
(EE) AIGLX error: dlopen of /usr/lib/dri/fglrx_dri.so failed (/usr/lib/dri/fglrx_dri.so: cannot open shared object file: No such file or directory). According to the Modular X Migration guide:
Note: With modular installed, external drivers such as nvidia-glx and wacom as well as some vnc apps may not work if they install things to
/usr/lib/xorg/modules. Many of these will have modular X detection added to the installation process.
The ati-drivers ebuild does have such detection, and the requested library was installed in the new location (
/usr/lib/xorg/modules/dri) however, it looks like the code trying to load the DLL is still expecting it in the old place? I tried the most obvious first.. create a symlink from the new location to the old. That seemed to really open things up.
# glxinfo direct rendering: Yes server glx vendor string: SGI server glx version string: 1.2 ... client glx vendor string: ATI client glx version string: 1.3 ... OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI MOBILITY FireGL V5200 Pentium 4 (SSE2) (FireGL) (GNU_ICD) OpenGL version string: 2.0.6119 (8.30.3)
I still, however, saw an error message:
AIGLX error: dlsym for __driCreateNewScreen_20050727 failed (/usr/lib/dri/fglrx_dri.so: undefined symbol: __driCreateNewScreen_20050727. This seems not to harm anything, and the screen is so darn beautiful I just want to use it for awhile.
Why not. Sound next. In the kernal config, I enabled support for ALSA as modules. I enabled Intel HD Audio PCI Driver for the kernel-based hda-intel module. I didn't have to set up any of the dmix stuff I used to, as (I seem to remember reading) that's all built in these days. Everything "appears to function" right out of the box. Goodness!
