Installing Archlinux
Migrating from Debian Testing Dec 2014.
Migration notes:
- Backing up rootfs to bns-readynas
- Script in archtools
- Backing up home to 16G flash drive
- rsync -avz . /media/berocs/DTM30/
- Scratch the above, flash drive is 16G, need 33G. rsync-ing to nfs:/bkup.
Fixing the Thinklight
Ever since I bought this laptop, the Thinklight hasn't worked, and I just assumed it was a casualty of having libreboot on the system. Today, however, an irc member on #libreboot pointed me to a German forum post which discussed a hardware issue and solution with X200 Thinklights.
I set out to make the same changes to my X200, and found that it worked! My Thinklight now operates nominally, with two tiny wires run behind the ribbon cable and soldered to the connector and LED.
Resurfacing the keyboard
--> This process isn't permanent. For me, the new surface lasted about two months before wearing away.
This laptop isn't exactly new, and one of the most obvious signs of wear has been the "slick spots" where the texturing on individual keys has worn down. Once again, an irc user came to my aid, and informed me of this German wiki page, where the issue is tackled.
I.. can't read German, so the page was loosely translated mechanically, and I tried to put the pieces together. Here's what I got:
- Clean the keyboard really well (dish soap, microfiber cloth, isopropyl)
- Get some clear coat matte finish wheel spraypaint (duplicolor brand)
- Paint the keyboard?
I wound up buying "Dupli-Color wheel matte clearcoat" which is product "HWP106"
I only washed the keyboard with a toothbrush and hand soap, drying with a microfiber towel. I didn't clean the keyboard as well as I should have, it would get perfectly clean, and then immediately some dust would settle on it. Oh well, the result still turned out OK.
I added layers until the glossy spots were just barely visible, with 10 minutes between layers.
Now to find out how well it holds up!
Firefox doesn't play nice with GTK Themes
What's happening is that lxappearance sets the gtk2 theme, and firefox uses the gtk3 theme. You have to look at both.
GTK2 is ~/.gtkrc-2.0
GTK3 is ~/.config/gtk-3.0/
Using a Brother DS-620
Forum post read it all the way through.
Libreoffice keeps segfaulting
Libreoffice would crash almost as soon as it lost focus as the main window in i3.
to fix this I had to edit the version of gtk being used in some configuration files.

It might be possible to put a better (quad core) cpu on the board according to someone on IRC.. An example being a X5460.
It also might be possible to expand the amount of storage with http://www.thinkwiki.org/wiki/Intel%C2%AE_Turbo_Memory_hard_drive_cache
Setting firmware options
Use nvramtool to set options. -h for usage.
This doesn't work on Libreboot 4.0, should be fixed in future release according to chatter on #libreboot.
