| AMD
Radeon driver sucks, won't go over 1080p; and Dune (AMD chipset) overscans so you can't see the edge. The only fix I found was to use xrandr. It kinda sucks though bc it's a resize solution that blurs all pixels. Cest la vie. xrandr --output HDMI-0 --set underscan on xrandr --output HDMI-0 --set "underscan hborder" 40 --set "underscan vborder" 22 Let's try the binary ATI driver. lspci -vvnn | grep VGA [...] Advanced Micro Devices, Inc.

For 4k video on an nvdia chipset (like wimpy), first get Ubuntu to use nvidia's driver:
Next, here is the "magic super-secret" Seiki 4K goo that should go in xorg.conf (if needed).

| Ubuntu repo management |

To see what repos Ubuntu is currently using:
cat /etc/apt/sources.list |
| Ubuntu upgrade from command line |
|---|
To update ubuntu from an i3 terminal:
sudo apt-get update # Fetches the list of available updates sudo apt-get upgrade # Strictly upgrades the current package sudo apt-get dist-upgrade # Installs updates (new ones) |
| Ubuntu synaptic driver (Macbook Pro trackpad) |
|---|
su - synclient -l # lists all params synclient PalmDetect=1 # temporarily change settings

| bitpost LAN IP addresses |
|---|
All IP address management happens on bitpost, via dnsmasq, which, rocks.
Initially set up bitpost with DHCP as follows:
config_eth0="dhcp" config_eth1="192.168.22.1/24" Turn DHCP-assigned IP into static as follows:
dhcpcd[3867]: eth0: carrier acquired dhcpcd[3867]: DUID 00:01:00:01:1a:c3:6f:da:e0:3f:49:a3:4b:d9 dhcpcd[3867]: eth0: IAID 49:a3:4b:d9 dhcpcd[3867]: eth0: rebinding lease of 66.57.227.83 dhcpcd[3867]: eth0: leased 66.57.227.83 for 86400 seconds dhcpcd[3867]: eth0: adding route to 66.57.226.0/23 dhcpcd[3867]: eth0: adding default route via 66.57.226.1
config_eth0="66.57.227.83/23" routes_eth0="default via 66.57.226.1"
We will monitor and log success here to see how it goes.

mdraid has not received the polish it needs to Just Work. It has serious flaws that after hours of learning, still leave you unsure and hanging and most likely bailing out of the entire process. But it is the best thing we have on the planet, so let’s distill it down to the essentials.

| thedigitalmachine LAN IP addresses |
|---|
| We want all IP address management to happen on the Buffalo DD-WRT router, as much as possible.
Ideally, static IPs will be served up to every known box based on MAC address. Then no matter what OS is booted, the machine will have the same name and IP address. The router is slick, it can do it, but be careful to Save AND Apply changes there. DHCP dynamic assignment IP range is 2...99, keep static IPs out of this range. every [/etc/hosts] should include this block: # ======================================================================================== # MDM My LAN names v10 192.168.21.1 tdm 192.168.21.200 buffalo # hardcoded Buffalo DD-WRT router IP # MDM Buffalo DHCP-provided static IPs assigned by MAC addresses # It's important to assign static IPs via router # It will always give the same IP regardless of OS # And it has the ability to provide the names via local DNS (I think!) # NOTE THAT 192.168.21.2-99 are RESERVED for dynamic IPs 192.168.21.132 wimpy # F4-6D-04-25-9C-60 192.168.21.133 wallee-wireless # macbook pro 00:26:bb:07:d3:7d 192.168.21.134 wallee # macbook pro 00:26:4a:18:ed:58 192.168.21.140 babe # andrea's ipad2 04:54:53:3A:7B:2A 192.168.21.179 dune # 00:1f:e2:07:2d:0e # TO BE ADDED UPDATED AND VERIFIED AS NEEDED # NOTE THAT 192.168.21.2-99 are RESERVED for dynamic IPs 192.168.21.4 darthfun # mike's iphone 00:26:B0:99:7F:7E 192.168.21.5 eetee # ipod touch 8gb 00:26:b0:59:4a:94 192.168.21.6 sweepea # girl's d-link card 00:1e:58:96:3a:2a 192.168.21.7 wiihii # wii 00:21:47:ba:c8:c2 192.168.21.8 iroku # roku wired 00:0d:4b:49:a6:30 192.168.21.9 irokit # roku wireless 00:0d:4b:49:a6:31 192.168.21.10 wynter # bailey's win7 laptop 00:11:F5:89:7B:00 192.168.21.11 hermione # andrea's dell inspiron 00:24:D6:78:42:A8 192.168.21.12 toothless # wren's eee 1C:4B:D6:A3:E1:28 192.168.21.13 dunno # 00:0f:b5:f6:99:d2 192.168.21.16 jackwhite # wren's iphone 54:26:96:BB:A4:CD 192.168.21.193 hermione-wired 192.168.21.194 toothless-wired # MAC address 48:5B:39:2B:8F:E8 192.168.21.195 6c-blade1 # ======================================================================================== |

| Creating a new ssh key pair for no-password access to a remote system |
|---|
Say you've got a new machine with user [m] and you want to connect to it, do this:
wow I just had serious issues with basic ssh usage, so i'll put a summary on the wiki
basically most misunderstandings stem from describing these two:
client: machine that is trying to ssh into the server
server: machine that the client user wants to get to
most poor sots are just sitting on the client
and they create a pair and push their public key to the server
but in my case, more often, i want to create a pair on the server
and push the private key to the multiple places i need to connect FROM
when doing that, you have to push the public key into the server's authorized_keys
and configure the client to juggle multiple private keys
create a key pair:
ssh suser@server
ssh-keygen
use defaults
will create:
.ssh/id_rsa (private key)
.ssh/id_rsa.pub (public key)
put the public key in place:
cd .ssh
cat id_rsa.pub >>authorized_keys
put the private key on the client and configure:
scp id_rsa cuser@client:.ssh/id_rsa_server
ssh cuser@client
em .ssh/config
Host tdm thedigitalmachine.com
Hostname thedigitalmachine.com
IdentityFile ~/.ssh/id_rsa
User m
Host server
Hostname server.com
IdentityFile ~/.ssh/id_rsa_server
User suser
all is full of light

| Back up a linux system to a second bootable drive |
|---|
Steps:
These are the steps for backup of the dune box to the /spiceflow/2.0tb-newmovies/ drive. When we're done, we'll boot from that drive to prove we have a working standby system. rsync does an excellent job of copying just what we need. Test it with this: # a (archive mode -rlptgoD) v (verbose) x (don't cross filesystems) h (human-readable) n (dry run) rsync -avxhn --progress / /spiceflow/2.0tb-newmovies/ Do the job with this: rsync -avxh / /spiceflow/2.0tb-newmovies/ sent 28.10G bytes received 8.64M bytes 15.63M bytes/sec total size is 39.57G speedup is 1.41 There was def some old stuff in there worth cleaning up: /home/m/development/svn/mythtv... /var/tmp xbmc log files etc Next we fix /etc/fstab on the new drive to use the drive as root. Original config: /dev/disk/by-label/d-g2-root / ext3 noatime 0 1 /dev/disk/by-label/d-sp-20newmovies /spiceflow/2.0tb-newmovies ext4 noatime 0 2 New config (remember tho, we lose the 2gb drive): /dev/disk/by-label/d-g2-root /root-hot-drive ext3 noatime 0 1 /dev/disk/by-label/d-sp-20newmovies / ext4 noatime 0 2 Note: this never worked out for me due to my system's mix of ext3 and ext4. I'll retry once I migrate everything to ext4. Next, grub: mount /boot em /boot/grub/menu.lst Orig entry: title ----- linux-2.6.34-gentoo-r11_withext4 root (hd0,0) kernel /boot/linux-2.6.34-gentoo-r11_withext4 root=/dev/sda4 Add a new "standby" entry under it - do a "df" to find the root: title ----- ==STANDBY== linux-2.6.34-gentoo-r11_withext4 root (hd0,0) kernel /boot/linux-2.6.34-gentoo-r11_withext4 root=/dev/hda1 Then reboot to standby and see what we have... (no "latest" video library etc., but otherwise the same?) |
| wallee gentoo networking |

| Laptop has both wired and wifi adapters.
We set up custom network interface names to make it more clear. I had installed several tools when attempting to get this going. DO NOT DO THAT, they interfere with one another. Removing NetworkManager and going with the highly-recommended wpa_supplicant and its graphical tools wpa_gui and wpa_cli. I'm documenting this since it's so basic yet such a bitch. /etc/udev/rules.d/76-mdm-net.rules # This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.

# line, and change only the value of the NAME= key.
# MDM following this to change nw interface names:

Next you have to set up these weird symlinks: cd /etc/init.d ln -s net.lo net.lan0 ln -s net.lo net.wifi0 Now add them to runlevels: rc-update add net.lan0 default rc-update add net.wifi0 default Now add them to runlevels: rc-update add net.lan0 default rc-update add net.wifi0 default Fix the system so that only one is required for startup to work... /etc/rc.conf rc_depend_strict="NO" No, we're not even close to done yet... We have to CUT the firmware out of the proprietary driver. Wow. su - emerge -av b43-fwcutter # NOT THIS, DAAAMN: bcm43xx-fwcutter emerge -av sys-firmware/b43-firmware export FIRMWARE_INSTALL_DIR="/lib/firmware" mkdir macbook_bcm43xx_wireless_driver cd macbook_bcm43xx_wireless_driver wget http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2 tar xjf broadcom-wl-5.100.138.tar.bz2 b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.o modprobe b43 /etc/init.d/net.wifi0 start Nope. What a fuckbucket of retardedness. Look at the notes this guy made - brief but heavy - i think i need to purge b43 and get the "wl" driver working instead. |
