Gentoo on the Lenovo Thinkpad Edge 13" Intel
I needed to buy a laptop for the moment. Simple requirements..
- Supported by Linux
The Thinkpad Edge 13" meets all the requirements. Theres a few thins I had to do make everything work.
- make.conf flags. I've kept it simple. CFLAGS="-O2 -pipe -march=native" The version of GCC I am using supports all of the i3's quirks and features. You can check to see if "native" will support your cpu by using the following two commands :
# cc -march=native -E -v - </dev/null 2>&1 | grep cc1 # echo | gcc -dM -E - -march=native
- Internal Sound card to get jack sence and for it to disable the internal mic and speaker when the jack was used, edit the following file :
At the end of the file add the following :
options snd-hda-intel model="olpc-xo-1_5" enable_msi=1
By using alsa-info we can find out we have a conexant pebble audio chip. Conexant CX20582 (Pebble) From that we can check out:-
To see all the possible modes for the 5066 chip, there is a few but the one that worked for me was "olpc-xo-1_5" In addition to make jacksense work we can look at :
# modinfo snd_hda_intel
This will tell us we can use msi=1 to enable the jack sense message bus.
- Much to my annoyance the USB chipset on this machine is the Intel 3400 series that have a bug related to there rate liming hub. What this means is that for me my Edirol UA-25ex can not work in full duplex mode with USB2..... You also must have the following two options on in your kernel :
This will help with some of the nastiness of the usb chipset. I still needed to turn off "Advance" mode and swap to 41000khz. Annoying but its much better then nothing.. thanks Intel...
- Intel video card. This one is pretty easy, once you understand how KMS is different. Ensure your kernel has NO other VGA/VESA drivers apart from the below :
CONFIG_DRM=y CONFIG_AGP=y CONFIG_AGP_INTEL=y CONFIG_DRM_I915=y CONFIG_DRM_I915_KMS=y
With the above settings on boot your console will switch to native resolution. Ensure Xorg is using the "xf86-video-intel" driver and your done. No need for any addition tools, userspace mods or kernel boot options!
The card reader,wifi and ethernet work fine. I am unable to test the eSATA, HDMI and vga port.
