I recently asked the question, as yet unanswered, if versions of CUPS newer than 1.5 support the "columns" option. Starting with version 1.6, the columns option is no longer listed in the...

I use an older version of CUPS. I recently looked at the documentation for CUPS 1.7, and saw that there is no longer a "columns" option. The last version that has "columns" is 1.5. Has "columns"...

I had to set up a wireless mouse on another computer for middle button emulation. I eventually found the "xinput" command, which provides the necessary capability. However, I discovered that if I...

This works even better:

xinput --set-prop 8 265 1

Actually, this works just fine, and is much easier:

gpointing-device-settings

It seems that "\[" does have the desired effect of matching a literal "[". However, when used with the cursed ".{,50}" construct, it does not behave quite the same way as "[[]". So, I will use both...

schragge: thank you for the reply. I didn't know that the {,m} form was non-standard. The man page lists it as acceptable.

papibe: The expression as you wrote it works perfectly. On re-reading...

I am trying to extract a string from the output of a DICOM directory
parser. The string I'm trying to match looks similar to this:

The USB stick worked fine on two other boxes, so I'm pretty sure it's OK.

I have a computer that is loaded with 12.04 LTS as its only OS. The other day, it stopped booting. When powered on, it gets to the BIOS splash screen, then goes dark, there is a brief activity from...

nvidia-settings --assign CurrentMetaMode="DFP-0: 1920x1080 { ViewPortOut=1820x1020+50+30, ViewPortIn=1920x1080 }"

Wow. Worked like a charm. I did have to tweak the "ViewPortOut" settings a...

Firstly, thank you for your help. I've done a little more digging, looking at forums related to overscan issues with the Sony Bravia HDTV series. There are references to setting the display area to...

I am using a Logitech M305 wireless mouse with a computer running a fresh install of 12.04. I cannot get 3-button emulation to work. "dpkg -l" shows that "xserver-xorg-input-mouse" is installed,...

Thanks to all who made suggestions. It turns out there is an issue with some CPUs that causes this problem. It seems to be related to lack of input from the mouse for long periods. The whole...

I am working with some MySQL databases, and often need to print out a table that is over 200 characters wide. I can view the table onscreen using "less -S", but for a printed copy, even with my...

I need help to create an avi version of Gojira from a DVD. I am using Ubuntu 10.04. I prefer to use CLI tools. I generally use ffmpeg for transcoding, as I have had problems with the A/V sync...

If I just start pan, then immediately select...

I don't have an answer, but more info.

I use an HP Laserjet 6P at my office. When printing directly from the command line, all is good: 'ls|lp' gives a nice print out. However, whenever I would...

Yes, it's correct. Running 'du' on the root directory ('du /') can take a LONG time to read all the directories and sort the output, so after getting the above errors, it should eventually give you...

My favorite way to see where all my disk space is going (from terminal):

$ sudo du /|sort -gr|more
