Power options in 12.04 system settings has only one option: "Suspend when inactive", while I can't see any obvious settings I can change so that the system is always on - without locking the screen after 10 minutes of inactivity.

How can I change power options to make my system "always on"?

Totem, EOG, have dark toolbars for some reason:

while other regular GTK3 applications have expected toolbar:

This doesn't look like preferred way, so why is it like this and how can I set all GTK3 applications to use uniform toolbars?

Accidentally, I made a mistake with files in /bin/ folder, and now I learned that some of it need to have SUID bit. Can someone please do ls -l /bin/ and paste which files doesn't have -rwxr-xr-x flags?

bless seems slightly better to me then ghex, but it has this ugly default font I can't stand.

My system monospaced font is set to Droid Sans Mono, size 9 and bless uses Courier New, size 12. It's too big and not preferred here, but can't find way to change it. Don't know if this is because it's mono developed, don't praise that either, but I searched in all folders where bless is "unpacked":

/usr/lib/bless  
/usr/share/bless 

and then:

~/.config/bless

There is no file where font is defined.

I don't even have Python 3 interpreter currently, and was surprised by this Wikipedia article: link while I searched for 12.04 release date.

It mentiones Python 3.2 as default Python interpreter in Ubuntu 12.04, while IMHO I wouldn't have expected Python 3 so soon.

Is Wikipedia information correct?

I found also this: link but it's not clear as which would be default

When I execute grep from within gnome-terminal, I get colored output - easily noticeable match, line-numbers (-n) with different colors etc

But when I execute exactly same grep command through bash script I get plane output, without coloring

Is there a way I can get colored output by using bash script?

There are many clipboard managers available.

The first one I used, I found out if messes clipboard history if clipboard contents was multiline - which I found to be very lame and naive

Second one which I use now is also faulty - I wanted recent clipboard content and I found it's not present in history. I deliberately copied piece of text and text is not copied in history so I can't reuse it, although if I select edit clipboard I find the contents that I just copied

Can someone with more experience suggest reliable clipboard manager, with panel icon or indicator icon feature?

I have some data and want to represent it on log type x-axis

How to do that with LO Calc?

I actually want to ask two questions:

1. Where can I find more about available arguments/parameters shortcuts for Exec entry in desktop files (like %U, %u, %f...)

2. Main question, how to pass file as argument on .desktop launcher for wine application?

I found searching here this suggestion: z:%f which is of no use to me, as if I simply run .desktop file without passing file on it, it assumes that argument is z: and starts scanning z: "drive"

Example:

[Desktop Entry]
Name=Some Windows program
Exec=wine "program.exe" z:%f
Type=Application
Terminal=false
MimeType=application/docbook+xml

I want to drop XML file on my custom .desktop launcher for this wine application and I can this way. Problem is that if I click on launcher icon to evoke this program, argument z: is always passed on it and that's not acceptable

This is second time I get segmentation fault error when I try to run GhostScript on any PDF file with pdfwrite
First time it was my previous Ubuntu 11.04 distro, which afterwards I completely remove (not because of gs), format my drive etc, and then install 11.04 again

I don't know what could be the problem. I work with GS a lot, and now all of a sudden I start getting this errors on any file, like something went wrong with this package or some of it's dependencies.
I searched Synaptic history if there maybe some recent update could cause GS crippling but there was nothing

I reported problems in the past (at least two times) on GS Launchpad branch, but no one even replied, and as a matter of fact no one ever replied to me on Launchpad for any report I issue, so I thought to remove completely ghostscript and install some other version.
At first I thought to add Debian stable repository, and install better tested version, but it turned out that perhaps that's not very good idea - adding Debian repository in Ubuntu.

As I can't "force" Synaptic to some previous GS version (as there is only one it seems - problematic one) I don't know how to approach this problem and wanted to ask how to install previous version, 8.71 preferably, because that's the last version in Debian stable.

Update:

I removed GS 9.01 (and bunch of other packages on the way) and followed Boris' advice, as I didn't know what else can I do.

I installed:

libgs8_8.71~dfsg2-9_i386.deb
ghostscript_8.71~dfsg2-9_i386.deb

and tested GS interpreter and all was working fine.

Now I wanted to put back all those packages removed by GS 9.01 removal, and I needed to first install ghostscript-x:

ghostscript-x_8.71~dfsg2-9_i386.deb

This is where problem begins:

Error:
Breaks existing package 'gsfonts' that conflict: 'gs'.
But the '/home/zetah/gs/ghostscript-x_8.71~dfsg2-9_i386.deb' provides it via: 'gs,gs-afpl,gs-esp,gs-gpl'

I didn't want to brake things so I removed just installed libgs8 and ghostscript and tried to remove gsfonts package (which additionally removed abiword, gnumeric,..) and then install all again.
But I found out that gsfonts is required by ghostscript and installed whenever ghostscript is installed (so ever before being able to install ghostscript-x package).

Now after installing libgs8 and ghostscript, when I try to install ghostscript-x I get:

Error:
Breaks existing package 'ghostscript' that conflict: 'gs'.
But the '/home/zetah/gs/ghostscript-x_8.71~dfsg2-9_i386.deb' provides it via: 'gs,gs-afpl,gs-esp,gs-gpl'

It's exactly the same if I try with Ubuntu 10.10 ghostscript 8.71 packages from Launchpad

Example script error.sh:

#! /bin/bash

zenity --error --text='Something very bad has happened!'  

My incron-config:

~/Documents IN_MOVED_TO ~/scripts/error.sh

If I run error.sh in terminal GUI dialog pops, but not in above incron scenario.

How can I make zenity to pop that dialog when I move file in Documents folder?

Spy++ comes with paid version of MS Visual Studio as

utility that gives you a graphical view of the system’s processes, threads, windows, and window messages.

and it's not only utility on Win32 that offers this feature, but I use it as popular example.

It lists all UI elements of all running applications, and user can use "Find Tool" to locate UI element of interest and get response dialog with versatile information about that object, like UI control name, text contents, and many other data of potential interest to a programmer.

I'm interested in similar GTK application which can at least return GTK UI element (widget) name and extracted text contents of that element of arbitrary running process.

I couldn't find anything related using Google

I found this answer how do i... but it simply doesn't work - it did not rename any file for unknown to me reason

Before I started to search around I thought that it should be easy task even for novice penguin, but it doesn't seem so for me.

For example, I simply can't tell ls to list all *.txt in all subfolders, which was surprise to me (without grep or similar).
Then I found find and find . -name name_1.txt lists files fine, but

for f in $(find . -name name_1.txt) ; do echo "$f" ; done

splits whole file paths with space as separator, so it's unusable to pass that output to some command like mv or rename

I want to ask whats wrong with above command and if possible some nifty oneliner so I can recursively rename name_1.txt to name_2.txt

I use mainly Terminator, and it's usually opened with 3 split terminal windows. I also use Gnome terminal for various reasons.
I'm wondering how is bash history handled in this case as I sometimes miss previously issued commands when I run history

For example, my prompt shows current bash history line (\!) and if I launch Terminator with 3 split terminal windows I get same history line (let's say 100) on all terminals. Which history will be saved?

Also launching Gnome Terminal after using Terminator I get line 100 at startup regardless all commands issued before in Terminator

I launch some text mode program (which accepts mouse input, like MC...) in text terminal and want to be able to use my mouse.

Is there some command I should enter to enable mouse support in this text terminals?

/desktop/gnome/peripherals/keyboard/general/disable_indicator in gconf is set to yes

Additionally I restarted, but it's still there.

Maybe there is some setting buried in CCSM?

here is screenshot of what I'm talking about if it's not clear:

I want to remove it if possible

Example:

I build/install SoX myself, as provided Ubuntu package did not include additional audio format libraries that I might use and it's one of the packages I want latest version anyway.

Now I want to install eboard with Synaptic, and it wants to install SoX, but as mentioned SoX is already installed and working perfectly and I don't want to mess it with another install while I want to install eboard without building it from source.

This is example to problem I faced couple of times and thought to ask what Linux users do in such cases as I'm a new user.

I've downloaded some nice themes, icon packages, and pointers from sites like gnome-look.

Now, what do I do to use this theme? Do I have to save it in /usr/share/themes?

Ubuntu 11.04 (PC-1) is connected to PC-2 (Windows XP) with LAN cable (crossover direct cable)
Internet access is through USB wireless modem accessing router in separate room

If I boot in Windows 7 (PC-1 has dual boot) I have no problem to connect to PC-2, at the same time being connected to Internet, even sharing my Internet connection with PC-2. I set static IP address and Subnet mask on both PCs and that's all for bare connection. Additionally I have set Remote Desktop Sharing and Internet connection sharing, which works as expected.

My problem:

1. I can't find a way to connect Ubuntu with PC-2 (Wired LAN connection)
2. When I was using Debian (month ago, as my first Linux experiance) I used Wicd and I could connect to PC-2, but I could not have Internet connection at the same time (either Wired or Wireless)

Can someone enlighten a bit this network issues, as man pages or help files aren't for bare mortals like me, but perhaps for network experts, as I did not understood a word in it

Thanks

As example to my question, my ~/.bashrc file contains this lines:

export LD_LIBRARY_PATH=/opt/intel/mkl/lib/ia32:$LD_LIBRARY_PATH
export LD_PRELOAD=/opt/intel/mkl/lib/ia32/libmkl_core.so

so that Numpy (Python) could find libraries that it needs to run, as it's build with MKL and Intel compilers. This workflow isn't the best, but that's another story.

My question is how can I pass arbitrary variables (like those in ~/.bashrc) when I run program with 'sudo' (but not root)?

Currently, if I run:

sudo python -c "import numpy"

I get an error:

ImportError: libimf.so: cannot open shared object file: No such file or directory*

Some suggestions as sudo -i or sudo -E does not change anything here.

Edit:

I can't answer my question (not enough points :D ) but I'll comment here, in a hope that there are other Linux newbies wondering about sudo traps.

[Only temporarily!] This works for me (~/.bashrc):

alias sudo='sudo env PATH=$PATH VAR1=SOME_VALUE VAR2=SOME_VALUE...'
