However, I recovered from the situation by rebooting, going into recovery mode, and getting it to fix broken packages. This ...

You can d it by selecting conservative governor and setting its sampling time. Here are instructions on how to do it. Please note that on modern Intel CPUs new driver is used, that calls conservative governor a "powersave" one.

Looking at your sudo parted --list output, you've put your boot partition onto the LVM... Bad idea! Head to The Linux Documentation project to read why you shouldn't... boot is not included on the LV because bootloaders don't understand LVM volumes yet. It's possible boot on LVM will work, but you run the risk of having an unbootable system. [sic]

Update: Scratch that below, that only works temporarily until I restart the computer again. Then it goes back to not displaying anything upon boot up. Solved the problem via recovery mode and dpkg system repair. Apparently the display module was actually corrupted when changing the settings.

Theoretically by uninstalling the packages installed (only remove the ...

I had working nepomuk in Kubuntu for a long time. I've upgraded Kubuntu to 14.04 and then 14.10, and FWIW I no longer have any nepomuk packages installed, only baloo. So one of those upgrades removed nepomuk for me. I didn't try to remove akonadi packages; Akonadi isn't causing any problems beyond the AkonadiTray widget that never does anything. The ...

My laptop's specs are similar to yours but I have more RAM. I have no problems with lubuntu 14.04 Even when I first got my computer 5 years ago I found the kubuntu at the time was a bit slow on it. I don't think that's an option. KDE (kubuntu) and Unity (ubuntu default) are designed to be fancy and beautiful, not lightweight. Ubuntu with gnome or Xubuntu ...

You will probably get more technical and possibly better answers from others after I say this, but I honestly feel you need to hear what I have to say before you do anything else.

In order to open your terminal in Unity, press Ctrl+Alt+T, or press Super, then type 'terminal' and hit enter. Edit: I see that you're using Ubuntu 10.04, so ubuntu-desktop probably comes with GNOME, I'm not sure if that Ctrl+Alt+T opens the terminal then, but you can find it in the menu; Applications → Accessories → Terminal. It is also worth noting that ...

I'm going to reflect some bias here, a bias which appears to be unpopular. you see, I've been using Kubuntu and Ubuntu for various parts of a decade. I cut my teeth on Kubuntu for over a year, and for about the past 9 years, I've been using Ubuntu instead. I simply found too many unnecessary and nonsensical obstacles in Kubuntu that Ubuntu simply didn't ...

In this situation, I would install an entirely different desktop manager, since the problem is apparently with KDE, and use that for 24 hours, and then fix the actual problem tomorrow. You may already have one. Click the little ubuntu logo next to your login on the login window (it might be something else on kubuntu, have a look here to get an idea), and ...

Since you don't have a lot of RAM, Xubuntu or Lubuntu will definitely give you a better experience. You may want to try out Mint XFCE (http://www.linuxmint.com/release.php?id=22).

My guess is that It is linked with the parameter of your boot loader (grub by default). In the configuration file or at boot time edit the grub lines and look for a line like: linux /boot/vmlinuz-3.13.0-40-generic root=UUID=0x......-xxx ro quiet splash $vt_handoff if quiet and splash are missing, you will get a console start. If you use a "safe boot" ...

I would really like such a function aswell, but I have taken the habit from now on to disable the touchpad before closing the lid with the shortcut (Fn + F7 here, depends on make and model of laptop). Sure, this doesn't solve the problem at all, but it's a big start. If you don't have a keybind preset into your laptop, I'm quite sure there's a way to bind ...

If your system has moved to systemd, specifically the logind service, settings for the logind service will control the system's behavior when the lid closes. Specifically, look for the logind.conf file (probably at /etc/systemd/logind.conf), and edit it to set the HandleLidSwitch setting (to ignore). #HandleLidSwitch=suspend HandleLidSwitch=ignore After ...

Are your drivers for the network cards loading? A quick check might be to mouse over your network notification area or try to manually connect to a network (I'm not terribly familiar with KDE). Running lspci -vv might net you some information about the cards and what driver they are using , if they are using one.

You have an invalid locale name set - there is no such thing as "en_DZ.UTF-8" - which makes your system fall back to the non-UTF-8 "C" locale. That's probably what's causing your problem. I'm not using Kubuntu myself, but you should open the GUI for the language settings. Somewhere there you have probably selected Algeria as the country. To get a valid ...
