KFA2 Geforce 1080 on Asus Sabretooth P67

I'm running a Asus Sabretooth p67 motherboard with the latest BIOS @3602. After installing my KFA2 Geforce 1080, it'll freeze on the BIOS screen and boot won't progress. Keyboard is also unresponsive.

After some tinkering with it, I noticed in the changelog for BIOS 3602

"4. Fixed Nvidia GTX 680 hang when runing with UEFI driver."

Thinking the 1080 might be affected by this bug, entering the BIOS and changing "PCI ROM Priority" to "Legacy ROM" fixes this issue.

Note that changing this while using the RAID functionality might cause your machine to become un-bootable until you revert the setting back. I hear the EFI RAID ROM uses different drivers. You might need to reinstall the OS.

So it sounds like newer graphics cards these days have both an EFI and "Legacy" ROM on them. Only difference noticed so far is that I don't get a higher resolution on the POST screen. My 580 didn't have an EFI ROM.

Hope this helps someone out there.

Tiny Tiny RSS init.d Script

Shamelessly taken from
http://tt-rss.org/forum/viewtopic.php?f=16&t=1135&start=15#p14282

I've finally switched to an upstart script for booting tt-rss with some minor modifications to create a lock folder before starting the service.

Forcing G.DMT Modulation on a DGN3500

ADSL2/2+ doesn't work very well for lines with high attenuation as it spreads the downstream channel across higher frequencies than those used by ADSL1.
Higher frequencies are more sensitive to attenuation than lower frequencies causing a drop in noise margin. You may see a slower sync rate or even disconnects if it's severe.

Most ISP's default to ADSL2/2+ modulation. Sky made a move to ADSL2/2+ a year or two ago and I saw a drop from 6000kbps to 3000kbps on the downstream due to it.
Luckily due to the efforts of individuals and online communities, it's possible to force the DG834GT to use ADSL1 modulation bringing back the speeds lost when using ADSL2/2+.
I bought the DGN3500 to replace the DG834GT as I needed a gigabit ethernet router & modem. After browsing the webui, telnet, GPL sources, and various forums; I concluded the DGN3500 could not have its modulation forced. Few weeks ago I decided to backup my settings and perform a factory reset on the router as a recent update botched my port forwarding settings. I noticed something in the configuration file:

[30004]"DSL Mode"=MMODE

MMODE meaning multimode. So I re-configured my router, backed up my settings to netgear.cfg, and edited that line to

[30004]”DSL Mode”=GDMT

To force ADSL1 modulation.
And it works :)

Cleaning the Windows Driver Store

Starting with Windows Vista, the driver store is a trusted collection of inbox and third-party driver packages. The operating system maintains this collection in a secure location on the local hard disk. Only the driver packages in the driver store can be installed for a device.

When a driver package is copied to the driver store, all of its files are copied. This includes the INF file and all files that are referenced by the INF file. All files that are in the driver package are considered critical to the device installation. The INF file must reference all of the required files for device installation so that they are present in the driver store. If the INF file references a file that is not included in the driver package, the driver package is not copied to the store.

---

Nvidia, ATI and Intel driver packages can be a few hundred megabytes big as they are typically "unified" driver packages supporting a whole range of different devices. Additionally they release updates very often. As each driver is installed the driver store can grow to become quite large in size.

1 way to clean them is a laborious command line method which I won't talk about.

A much easier way is using this program http://driverstoreexplorer.codeplex.com/
It must be ran as Administrator to work properly.

rTorrent & Screen Upstart 1.3 (Updated)

Upstart script for rTorrent for Upstart 1.3 (and older?)
Upstart 1.4 supports setting uid and gid so we can use that instead of start-stop-daemon or sudo or su to correctly track the process id using expect daemon and tell it to send the proper kill signal (for rTorrent is SIGINT)

So what do we do for Upstart 1.3?
Well, we're forced to use either start-stop-daemon or sudo or su to start a process as another user. Even with expect daemon it always tracks the wrong process id and in my case causes shutdown to freeze as it tries to kill a process that doesn't exist.

My solution is to start a job that cleanly kills (by sending a SIGINT) rTorrent when you'd expect it to. In my case runlevels [016]

#rtorrent-start.conf

description     "rTorrent - ncurses BitTorrent client based on LibTorrent"

start on (local-filesystems and net-device-up IFACE=eth0 and runlevel [2345])
stop on runlevel [016]

console none

exec start-stop-daemon --start -c <user> --exec /usr/bin/screen -- -dmUS rtorrent /usr/bin/rtorrent
##

#rtorrent-stop.conf

description "Correctly ensure rTorrent shuts down gracefully"

start on runlevel [016]

console none
task

script
 if [ -f /home/ <user> /.rtorrent/rtorrent.lock ]; then
   kill -s 2 $(cat /home/ <user> /.rtorrent/rtorrent.lock | awk -F+ '{ print $2 }')
   rm -f /home/ <user> /.rtorrent/rpc.socket
 fi
end script
##

.lock file cleaning should be left for rTorrent as it usually removes it when correctly killed. If an old .lock file remains its a clear indicator that rTorrent did not correctly shutdown.
Won't hurt to remove the socket file though (if you use it). Saves adding it in .rtorrent.rc

UPDATE:
I've recently had some issues with UDP trackers and DHT causing some torrents to not start downloading at all even when the swarm is healthy. I've since given up on rTorrent and have started using Deluge, which is nice and compact with a sweet web gui.

Xorg modelines for LG 32LC46

Xorg modelines for LG 32LC46 as reported by its EDID because Intel can't parse the data completely (so it misses some refresh rates and resolutions). Had to plug this in to my old HTPC with an Nvidia ION to get this (with startx -- -logverbose 6)

XBMC with External FFMPEG

I used to do this awhile ago on my HTPC. Its pretty slow building XBMC on an Atom CPU. I gave up building my own builds because I ended up running in to problems (segfaults etc). When I installed 10.04 I decided I didn't want to install various build dependencies and libraries on my HTPC
Now I want Hi10P support on XBMC. An XBMC build compiled to use external FFmpeg libraries is the only way to achieve that until XBMC developers update the internal libraries (due after Eden apparently)
I now build XBMC and FFmpeg in a VM using VMware Player (which features (since version 3.0) the ability to create new virtual machines YAY!). Configure switches have been customised for myself. YMMV.
