So, I have gentoo up and running on my T40, and thought I’d share the resources that helped me get there.
For those interested, here’s the currently running kernel config.
I wiped the predesktop area. I don’t plan on running windows, and I’d rather have the disk space, thanks.
2.6 Kernel / Modules:
- Power Management – I stuck with APM rather than ACPI. I may try ACPI later, but not yet.
Graphics Support – I went with framebuffer support this time, and so far, I like it.
Make sure you compile framebuffer console support INTO the kernel.
- Sound Support – Alsa + snd_i8×0, as usual
- e1000 driver worked out of the box for the on-board Ethernet card
There is a new SF project providing a driver for the onboard Intel Corp. PRO/Wireless LAN 2100 card. The driver seems to work fine, I’ve not been using it long enough to complain.. ;) Also, there is a nice ebuild for centralizing wireless config. Sweet!
- emerge wireless-tools
- emerge wireless-config
- tweak /etc/conf.d/net and /etc/conf.d/wireless as recommended by wireless-config package
Noteable: associate_test_eth1=“MAC” was required to allow dhcp to finish initializing. I also provided wireless dhcp settings in /etc/conf.d/wireless rather than in /etc/conf.d/net.
- /etc/init.d/net.eth1 start
iwconfig (before setting any wireless stuff up) lo no wireless extensions.
eth0 no wireless extensions.

X Font Server and X11:
Finally, an email that concisely explains what the hell ‘unix:/7100’ actually DOES…

Anyway, what I’m trying to say is that -1 isn’t exactly a port number, but
rather a hint the X server and/or font server use to find this file.
For example, in my Redhat 7.1 installation, I have in XF86CONFIG FontPath “unix/:7100”
This 7100 is not a port number, since unix-domain sockets do not have
port numbers (an example where this would have been a port is with the
tcp transport: tcp/somecomputer.com:7100 – see man X(7) for more info).
This 7100 tells X to use the local file:
- ls -l /tmp/.font-unix/fs7100
srwxrwxrwx 1 xfs xfs 0 Jul 9 23:15 /tmp/.font-unix/fs7100
Which the font server (xfs) is listening on. Note the “s” in the beggining
of the ls -l line: this says this is a special unix-domain *s*ocket file.
