EDIT: Caveat emptor on Ubuntu distributions from 14.10 and forward - init was chosen over upstart and is being phased in the future. I don't know when that will be done nor what impact it will have on upstart scripts.
Extract from the page RentFree refers to; note that it assumes that you have created a user called bitcoinuser for the sake of security:
After having installed Bitcoin core on your machine, run the following command to start synchronising the testnet blockchain
bitcoind -testnet -daemon
The synchronisation starts as a daemon and runs in the background, you can issue the following the command to see the progress
To access the command line apis , just add ...

There's an upstart script for Ubuntu in the Bitcoin Core source tree. Using that is the most correct way.
However, I just login as the user account I want to run Bitcoin Core daemon, start a terminal (if I'm in the GUI), and run the following command to edit my crontab:
Then I add the following line:
@reboot bitcoind -daemon
Save the file ...
Once you've installed bitcoind, you should create a configuration file (stored in ~/.bitcoin/bitcoin.conf) containing at least an RPC username and password, and then you just run bitcoind to start the server.
Version 0.6.0 introduced more strict validity checks on the keys when loading a wallet, to prevent silent further corruption. It seems like you have a wallet where one or more keys are corrupted (the private and public one don't match, for example). You can try moving the funds away using an older version, but there is a chance that will fail.
I intend to ...
On Linux, the Bitcoin client data is kept in the .bitcoin directory in your home directory. Go to ~/.bitcoin/ and you'll see the files in there. You may need to toggle Show Hidden Files in your file manager in order to see the directory.
If you remove blkindex.dat, the client will have to redownload the blockchain. I just tested this locally by moving my ...

You can use logrotate.
Create a file named bitcoin-debug in /etc/logrotate.d.
This is the contents:
Replace /home/bitcoin/.bitcoin/debug.log with the actual path to ...
.exe files are for windows only. Linux systems do not use the same file extension or file type as windows. I assume you just want to create a Linux binary that can be used on all systems without installing all dependencies. To do that, you can use Bitcoin Core's depends system. Instructions are here: https://github.com/bitcoin/bitcoin/tree/master/depends.
This happens with many Ubuntu Apps. The simplest solution is to tap Alt any type the name of the menu item you wish to find.
Alternatively, hit Ctrl-Alt-F2, log in, type DISPLAY=:0.0 unity --replace hit Enter, and then do Ctrl-Alt-F7. The menu bars and the windowing system will reload.
The wildcard syntax is not supported anymore. Instead of 192.168.*.*, use 192.168.0.0/16. Instead of 192.168.1.*, use 192.168.1.0/24.
As an additional debugging step, try running netstat -antlp | grep 8332. If that produces output like the following, that means that it is bound to the port.
tcp 0 0 0.0.0.0:8332 0.0.0.0:...
Answers to your respective questions:
Since 0.12, bitcoind supports cookie file authentication. This means that on startup of bitcoind, a file with a random key in it is created. Anyone who can present the contents of that file to the running bitcoind is allowed access. Since bitcoin-cli runs locally and as the same user, it can read this file and do so.
I just installed bitcoind on an RPi and wanted to do this exact thing. Thought I'd post what worked for me:
$ bitcoin-cli getblockcount
Block height is 366678 at the time of this post...long way to go
I suggest to use one of the updated cpuminer versions which support more than one algorithm. This way you are also set up to mine different coins which use other PoW functions. The most versatile one is tpruvot's fork:cpuminer-multi. For me this one worked out of the box on a recent Ubuntu 14.04 installation.
The syntax is similar to all other cpuminer ...
If you're mining in a pool, bitcoind doesn't even have anything to do with the system. It doesn't need to be running, it doesn't even need to exist on your hard drive. The remote pool does that for you.
I would highly recommend using Ubuntu Server for this, as long as you know what you are doing without a GUI. Not having a GUI at all means smaller OS size and much less OS tasks. This translates into more power savings. If you are using graphics cards, a non-GUI OS will improve your mining performance. If using an ASIC/etc. you probably will not see ...
In Bitcoin Core 0.11 pruning is experimental, and incompatible with the wallet.
So turning on the prune= option automatically disables the wallet function.
In 0.12 the wallet will work with pruning (though you obviously won't be able to rescan past the pruning cutoff).
esplora is just the web ui frontend, you also need to setup the (forked) electrs backend for indexing and for providing the HTTP API that esplora queries.
electrs can index the bitcoin block chain using two methods: by reading the blk files directly out of disk, or by querying for blocks using the bitcoind rpc. The first method is significantly faster, but ...
Try starting with the -reindex command-line flag. That will rebuild the database on disk (as it seems corrupted), without redownloading the blocks you already have.
It's strange that wiping your datadir didn't help though.
To avoid having to redownload everything from the p2p network, which may be slow as you have to validate the whole chain, you can download the bootstrap chain file from bitcoincharts.com
It is also available through bittorrent, which may be faster for you. Here's a copy of the message posted above and in the forums that authenticate the file (through GPG).
This is kind of obvious, but have you tried going back through your backups, newest first, and using the first one which works?
You'll need to GPG decrypt the backup of course, but I hope that's not a problem.
Edit: I know you said you tried with just wallet.dat in ~/.bitcoin/ but could it be that you left the ~/.bitcoin/database/ directory with logfiles ...
OpenCL is not supported on 3xxx series cards. Although it's not completely impossible to mine on a card that old it will be very difficult. Also, a card that old will produce less than 1 MH/s which will only be fractions of bitcoins. I wouldn't waste my time fighting the Radeon 3600.
If you are serious about mining check out the 5xxx and 7xxx series ...
