Common use case for me and printscreen:
.pngGimpIt seems like the first three steps could be combined into a single key bind, e.g. printscreen auto opens Gimp, ready to edit. Is that possible?
I am using Ubuntu 14.04 and I have created a virtual machine with the same ISO. In the virtual machine the terminal window shows up with a strange transparent gradient that makes it unusable. How can I fix this?
According to this question, to get code my code work on this 12.04 machine I need to upgrade the version of SQLite to 3.7.11. However, on Ubuntu 12.04 the installed version of sqlite is
> sqlite3 --version
3.7.9 2011-11-01 00:52:41 c7c6050ef060877ebe77b41d959e9df13f8c9b5e
How do I upgrade SQLite (I'm stuck using 12.04)? If the answer is, "use this magic PPA", please tell me how you found it - I tried searching and left empty-handed.
After upgrading from Ubuntu 13 -> 14.04 emacs now wastes valuable screen space with silly buttons. How can I go back to a "buttonless" version of emacs?
When I run a command on a new machine (or install that I'm testing) I often find that the package needs to be installed first. This leads, for example, to the following sequence:
> colordiff
The program 'colordiff' is currently not installed. You can install it by typing:
sudo apt-get install colordiff
Argggh.
> apt-get install colordiff
Is there a way, when given the prompt that says the command You can install it by typing: sudo apt-get install XXXX to run sudo apt-get install XXXX without typing the entire line out? The best I can do is:
> apt-get install !!
but since some command (the shell?) is telling me what I should run, it would be nice if I could get that same program to run it for me.
Using a ext3 or ext4 file system, assuming that the files have similar checksums, would the following files:
8c87dba9cf4dbc27c0d54083311ffeef6821e8426f5a8d50165d84f5eef80103.npz
1.npz
Take up a different amount of space on the HD? I have many (10 to 100's of thousands) of these files so a difference, however small, would be worth knowing about.
I'm trying to run a pre-compiled program from
http://cherrypit.princeton.edu/donev/Packing/PackLSD/Instructions.html
The pages states that:
The executables only link in standard (OpenGL, libtiff, libjpeg, etc.) Linux libraries, and link openglut statically, which may cause failures on some systems. The programs are compiled at medium optimization, for a generic IA32 processor, on a Red Hat EL4 system. They should run on Red Hat (>=9) and Fedora (>=3) systems just fine, and hopefully other similar distributions as well.
A standard Ubuntu 12.10 distribution is unable to run the program with
./PackLSD.poly.static.x: error while loading shared libraries: libtiff.so.3: cannot open shared object file: No such file or directory
This suggests that I should install the dev versions of libtiff, but neither
sudo apt-get install libtiff4-dev
sudo apt-get install libtiff5-dev
seem to help. Am I out of luck getting this program to work without help from the author?
Edit: As requested. The output to sudo dpkg -L libtiff4 libtiff5

I'm not sure if this is a bug or I've done something wrong (or I simply don't know luatex well enough). This minimal example file test.tex
\documentclass{article}
\usepackage{luacode}
\begin{document}
A random number:
\begin{luacode}
tex.print(math.random())
\end{luacode}
\end{document}
Should compile with lualatex test.tex but fails with:
! LaTeX Error: File `luacode.sty' not found.
It sounds like something was messed up in the installation of luatex. They look to be installed:
> dpkg --get-selections | grep luatex
luatex install
texlive-luatex install
The file exists on my system:
> locate luacode.sty
/usr/local/texlive/2011/texmf-dist/tex/lualatex/luacode/luacode.sty
so I'm not how to troubleshoot this. Is the package messed up or is it a problem on my end?
I often have many terminals open when working (GNOME Terminal 3.4.1.1, Bash). Quite often I need to copy the results of one terminal into another. An common scenario:
terminalA> pwd
/home/hooked/foo
terminalB> cp * /home/hooked/foo
I usually end up copy pasting with the mouse. Is there a keyboard shortcut for what I'm trying to achieve?
I use my computer for scientific programming. It has a healthy 8GB of RAM and 12GB of swap space. Often, as my problems have gotten larger, I exceed all of the available RAM. Rather than crashing (which would be preferred), it seems Ubuntu starts loading everything into swap, including Unity and any open terminals. If I don't catch a run-away program in time, there is nothing I can do but wait - it takes 4-5 minutes to switch to a command prompt eg. Ctrl-Alt-F2 where I can kill the offending process.
Since my own stupidity is out of scope of this forum, how can I prevent Ubuntu from crashing via thrashing when I use up all of the available memory from a single offending program?
Open a terminal, launch python and if you have numpy installed try this:
>>> import numpy
>>> [numpy.zeros((10**4, 10**4)) for _ in xrange(50)]
* Warning: may have adverse effects, monitor the process via iotop or top to kill it in time. If not, I'll see you after your reboot.
Maybe I'm doing something wrong, but shouldn't the commands (run separately)
notify-send -t 1 "test"
notify-send -t 1000 "test"
notify-send -t 10000 "test"
have different timeouts? The first being nearly instantaneous, the second taking 1 sec and the third 10 seconds? In all cases it seems to take about six seconds for me.
Is there a way around this behaviour? As the developers label this as a "feature" instead of a bug, I would like some alternatives.
In the newest version of Ubuntu (11.10) when I run from the command line Gtk complains loudly (over several lines) each time a window is opened. The problem is clearly with the theme - if I change the default from Ambiance to High-Contrast this goes away. Some examples:
travis@hydrogen:~$ emacs foo.txt
(emacs:1550): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",
(emacs:1550): Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap",

travis@hydrogen:~$ evince test.pdf

(evince:1566): Gdk-CRITICAL **: gdk_window_get_pointer: assertion `GDK_IS_WINDOW (window)' failed
I like the themes and I don't want to part with them. How can I fix the command line verbosity from Gtk? I can simply hack the command line to filter out these messages, but I really don't like that idea.

Under Ubuntu 11.04, when I try to install pdftk via apt-get or synaptic, I get the following error:
Reading package lists... Done

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:
The following packages have unmet dependencies:

I know pdftk works just fine on Ubuntu on previous versions. How can I fix the dependencies so that I can now install pdftk?
