Ran into the same problem, but typing xinit into a terminal yielded no joy, just the message: Fatal server error: Server is already active for display 0 If this server is no longer running, remove /tmp/.X0-lock and start again. I'm running Ubuntu 12.04.2 desktop (64 bit) After a while of struggling with it I've got it to display the temperatures of my GPUs. I did the following: sudo apt-get install fglrx-updates fglrx-amdcccle-updates fglrx-updates-dev I then downloaded AMD-APP-SDK and followed step 12) in this guide: https://github.com/kanoi/linux-usb-cgminer/blob/master/linux-usb-cgminer#L117 to enable OpenCL. Unfortunately Ive now got a problem with the display - the right hand side of the screen wraps back round to the left (but not he other way around) This isn't much of an issue, it just mildly irritating. I have a feeling it can be fixed by manually altering the xorg.conf but I don't wanna mess with it anymore.

It is my understanding that those using the 0.7.2 or earlier clients will receive a warning dialogue box if they fail to upgrade in time, alerting them of the issue.
Yeah didn't that happen last time? When the chain forked I seem to remember getting a warning pop up in the client.

Economy / Speculation / Re: Will PayPal really use bitcoin?

The only use of paypal to Bitcoin is to be used like a scrow, just like they are doing now with fiat money.
Yeah why don't they just gradually change their business model. First they could accept Bitcoin alongside the service they already provide, then they could offer escrow and with their massive user base become one of the major escrow services. Not necessarily saying this is going to happen, but I find it annoying to read the posts saying 'bitcoin would destroy paypal therefore no chance of adoption'. Bitcoin would destroy paypal's current business model, but many businesses adapt and survive when disruptive technologies are created.

As I understand it, the qt client generates 100 addresses the first time it's run, and whenever a new address is required, it pulls one from the pool. at the same time, it generates a new one which gets added (keeping a constant pool of 100). This means that for every 100 addresses that get used, you have to make another backup of your wallet. Addresses don't only get pulled from the pool when you decide to create a new receiving address. They are used for 'change' transactions. These occur due to the way the protocol is designed.
As an example, imagine you buy your first bitcoins: lets say you buy 5, which get sent in one transaction to your first address. Now you decide you want to send 1 bitcoin to somebody - the client creates a transaction which spends the full balance of 5 BTC, 1 to the address of the person you are sending to, and 4 as 'change' back to yourself, a different address which you control. This address is pulled from the client's pool of 100 addresses, so you should back up after every 100 transactions.
I'm not sure exactly why it works like this, I'm sure there's a reason.
Armory is a client which works deterministically, meaning that new addresses are generated in a pre-determined manner. This means you only need to back up once. It's also a great way to store coins securely, if you have a spare old laptop to run an offline wallet.

Sold 1 BTC to BigBitz, apologies for being stubborn and not willing to send first, I've now seen your feedback here and you're obviously trustworthy. Can't be too careful though...
Smooth transaction, good guy to deal with.
