Hello, all; it's been a long time since I last posted.

I recently bought a Brother HL-L2350DW laser printer (to replace an HP OfficeJet 7612 whose print head failed).

Yesterday, the Brother...

I've just got an old Aiptek-compatible graphics tablet (304mm × 228mm) to work with my lenovo X220 ThinkPad with an additional external screen.

The primary display is the 13" built-in screen with...

Thanks for your help, 1Fallen, OldFred and C.S.Cameron.

This is going to be quite a long post... tl;dr version is: used GPartEd copy and paste, and now it looks stuck part way through pasting onto...

After not touching my old and in many ways "main" computer for some months, I booted it up about a week and a half ago to rip some recently bought CDs to keep the music on the NAS. And there, I ran...

Left-alt does not drag the window around. I put the pointer on the dialogue "frame", click with MB3, a contextual menu appears, I select "move"... and the top edge of the dialog won't move higher...

Following on from an old, closed thread, I have run into a frustration with Inkscape 0.9.2.

The Document Properties dialog is not resizeable, there are some options (borders and antialiasing) that...

I also get this problem, but not with all SD cards.

For example, a card used in a Canon G11 camera gets mounted automatically, but a card used in a no-name Chinese action camera does not get...

Thanks, deadflowr, I'll give those a try.

/home is on a physical drive with one or two other filesystems (maybe /films or /music); things like /boot, /var and /lib and / are on other physical drives.

OK, this is more or less the same question as in another thread, and I've not yet tried commenting out the lines in /etc/fstab as advised there.

I found that my daughter had been using the main...

My question is a mix of audio (therefore multimedia) and network streaming (therefore networking).

Here's the project: play my music collection (a mix of formats: ogg, flac, MP3, maybe even WAV...

Well, I connected this amp to the computer's S/PDIF optical output, just to make sure that the amplifier side of the thing was working. All's fine there. I'd still like to get the USB DAC working,...

I recently got a little TriPath amp with a built-in DAC, and I'm trying to get it to work with my main desktop computer running 14.04.

Here's what I see:

Tried to upgrade a few days ago, hardware is a dell R610 that had been working flawlessly but not being used much (I bought it second hand to learn about server hardware and administration, mostly)....

I was having problems getting Amazon lookups to work. Looking around on the web I came across several posts on various forums about the same problem. At least post was an appeal to petition the...

I was updating my library catalogue in Tellico a couple of weeks ago and found that Amazon lookups were no longer working.

I had to leave it for a while because I was too busy with other stuff,...

Well, I don't even have sound as root, now.

I decided to change the positions of a few things in the rack and route the cables differently so that they were neater and so it would be easier for me...

Thanks, that got it for me.

I have a little BT keyboard that I want to use for a few experiments, and for them I will need to know its MAC address.

So far, I've been trying hcitool and hidd but I get no results, even when...

Hardware is a Dell R610. I know, the fans are noisy; but still, I want to be able to make sounds from it.

Well, after reading around and finding no information that seemed helpful to my particular set of circumstances, I sat back and had a beer. Then I cooked a chicken curry for my daughter and me; we...
