I would like to configure my Ubuntu 12.04 server to synchronize its clock with a specific NTP server. Where to set this up?
I'd like to see if somebody has been trying to log-in by brute-force into my Ubuntu 12.04 server over SSH. How can I see if such activities have been taking place?
As VLC 2.0 is released, how do I get it in Ubuntu (XUbuntu actually, in my case) 11.10? Any PPAs or packages to download? The official page says "Ask your favorite packager..."
Can I configure Ubuntu to never install a specific package even if it is required by another package I install?
I'd like to use Alt+F7 to search for files in Double Commander.
But when I press Alt+F7 - the hotkey is intercepted and I am offered to move the window.
Settings - Settings manager - Keyboard - Application shortcuts doesn't show Alt+F7 to be bound to anything.
Where can I undefine Alt+F7 hot key then?
Surprisingly (as OpenJDK 7 was released to general availability about 4 months ago) Ubuntu 11.10 still uses OpenJDK 6 instead of 7 by default. How do I best fix this? I'd prefer to remove OpenJDK 6 completely and let OpenJDK 7 to be the default-jdk and default-jre.
I don't want the official Oracle tarballs, I want deb repos - the standard Ubuntu way.
I use 3 different languages (English, Czech and Russian) every day. I'd prefer to switch (preferably globally, I don't like per-window) between them with Left+Alt+Shift.
I'd also like to see the active language indication.
Unfortunately I couldn't find any obvious way to set this up in XUbuntu 11.10 - there is even no keyboard indicator applet available in the panel configuration. Any recommendations?
In Windows there is a version information page in an executable/library file properties window. How to view that info in Ubuntu?
In Windows there is a straightforward "Format" option in a flash drive's right-click pop-up menu. Where's that in Ubuntu?
From time to time I come up with ideas of actions I'd like to have available in the context menu of Nautilus. How do I add them there? Is there something like a Thunar UCA plugin for Nautilus?
Depending on nature of the text, sometimes line wrapping is convenient, sometimes it is just confusing. And every time I need to switch this (pretty frequently) I have to do to View - Preferences - Enable text wrapping - Close - four clicks, not mentioning all the hand, eye and thought motion. Can this be done a quicker way?
Most text editors have this two clicks away (in a menu) at maximum, some have it on a toolbar or a hot key, but I couldn't find any quick way in Gedit. Maybe there is a hot key I don't know?
Ubuntu seems to favour OpenJDK/JRE very much over Sun JDK/JRE. Even after I installed Sun JRE, JDK and plugin and spent some time plucking out OpenJDK-related packages, apt-get has installed them back with some packages as a dependency. Can this behaviour be corrected in favour of Sun Java packages? I'd like to have one and only Java stack installed (yes, it's a bit of OCD, but I like to have my systems clean) and want it to be Sun Java.
Update: as Marcos Roriz notes, the problem seems to be in default-jre (on which Java-dependent packages use to depend) pointing to OpenJDK, so the question seems to go about how to hack default-jre/default-jdk to point to Sun Java.
Because of bug #693758 I'd like to prevent apt-get upgrade and Update Manager from updating the "libgtk2.0-0" package.
How can this be achieved?
I'd like to output a list of all installed packages into a text file so that I can review it and bulk-install on another system. How would I do this?
For a task of mine I need to list all the files in a tree (a directory, all its subdirs, all subdirs of those, etc.).
I'd prefer to see them in Nautilus or Krusader, but a command-line solution is interesting as well (in this case I will need files full names, sizes and modification times to be listed).
I use to work at night and it is eye-hurting to watch at lightbulb-bright screens (I've got two - laptop's built-in panel and an external 18-inch CRT) in a dark environment. So I adjust my screens to be darker.
Can I do this a software way instead of pressing monitors' buttons that many times every time?
I am curious, does SSH compress its data before sending/receiving it? If it does not by default, then can it be turned on?
I've got a file said to contain information I was looking for. Unfortunately it is an executable instead of DOC (as it was meant to be) and the site I've download it from looks suspicious for me. If I was not using Linux, I'd run it on a VM or a separate PC. But running Linux, do I need to worry, or can I just run it with Wine? Can Wine system be infected?
What are correct places for:
- Global environment variables meant to affect all users?
- User-specific environment variables?
As Ubuntu 10.10 seems to neither detect my graphics card (Intel 82852/855GM) automatically nor use the corresponding Intel driver even after manually installing it, I am looking into manually configuring X (shouldn't I?). Where can I find the configuration files I need to edit?
