Patryk's questions

After I have placed my hard drive with Ubuntu 14.04.1 in a new pc system settings won't show up. I have tried:

sudo apt-get install unity-control-center

but I get this

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 unity-control-center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed
                        Depends: libcheese7 (>= 3.0.1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

what can I do?

EDIT

The issue may be connected with mesa packages that I had from xorg edgers and I have noticed that

• unity-control-center depends on libcheese7
• libcheese7 depends on gstreamer1.0-clutter
• gstreamer1.0-clutter depends on libcogl15
• libcogl15 depends on libegl1-mesa-drivers
• libegl1-mesa-drivers depends on libegl1-mesa-drivers
• libegl1-mesa-drivers depends on libglapi-mesa ( = 10.1.3-0ubuntu0.3 )

and I have installed :

libglapi-mesa 10.5.0~git20150105.21a280f8-0ubuntu0ricotz~trusty from xorg-edgers PPA.

I have tried installing it with:

sudo apt-get install libglapi-mesa=10.1.3-0ubuntu0.3

I have that PPA already disabled with

sudo ppa-purge  ppa:xorg-edgers/ppa && sudo apt-get update

I have been bothered by this issue for few weeks already. The problem started when I upgraded to 14.04. Parts of my screen are sometimes flickering like shown on 2 videos that links I attach below:

https://www.youtube.com/watch?v=FAg2uGABXQo

https://www.youtube.com/watch?v=ANgAl28P-YE

I was trying to record it with VLC but suddenly when I start recording then ... it stops flickering :)

I have no idea where can I file a bug for this and which package it may be connected with. Please comment with what it may be connected with and how can I resolve this.

I will post any relevant information regarding the packages if need be.

I use nvidia-334 from xorg edgers package ( 334.21-0ubuntu1~xedgers14.04.1 ) but I have also tried others and it's the same issue.

I have just installed Steam on my 64-bit Ubuntu 13.10 and it works well and I can play games, but each time I launch it I get the following prompt:

Steam needs to install these additional packages: 
    libgl1-mesa-dri:i386, libgl1-mesa-glx:i386

Some time ago I installed xorg edgers nvidia 331 drivers for my Nvidia 420M with Ubuntu 13.10.

Today I have run as usual

sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get dist-upgrade -y

And since then my laptop always boots into low-graphics mode prompt to ask whether to troubleshoot the problem, check logs, etc. but even after marking boot into low graphics mode it never does (it hangs in x but I can still CtrlAltF1-6. I have uninstalled my graphics drivers after that, reinstalled them (the same effect). Removed xorg edgers PPA, installed nvidia-319 drivers (the same).

Always low-graphics mode.

I have also had problems with 3.12 kernel that I have installed (manually from kernel.org but after I have completely removed them and upgraded GRUB; there is now problem with the drivers.)

I attach Xorg.0.log

I know how to change gnome's terminal font using the gui

let g:airline_theme='powerlineish'

I have just received my Nexus 4 and I want to plug it in to root it/copy files onto it but somehow I can't see it while I use

$sudo fastboot devices

I am using this version of fastboot on my ubuntu laptop

android-tools-fastboot 4.1.1+git20120801-1

EDIT

While the issue of rooting the device was solved (simply fastboot only sees devices while they are in bootloader) I still cannot see the device while I plug it in the system.

Today I wanted to go through my photos collection but I have realised that it is quite difficult to go through thumbnails in Nautilus as it is using the free space in the window very inefficiently, e.g.

Is there any other option to use it less "padding" , free space between other photos ? Or should I use other window manager to achieve this ?

I have tried to resize (shrink) my NTFS partition so that I will be able to get more space for my ext4 Ubuntu's (12.04 64 bit) partition but after the partition has been resized I am unable to mount it. I used Gparted to do this.

I assume there is a problem somewhere with the partition table but I do not know where and how to fix it.

This is what I get in Gparted information window on NTFS partition:

HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
   or it was not setup correctly (e.g. by not using mdadm --build ...),
   or a wrong device is tried to be mounted,
   or the partition table is corrupt (partition is smaller than NTFS),
   or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/sda5': Invalid argument
The device '/dev/sda5' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

I would like to check which 'technology' (a/b/g/n) is currently used by my WiFi card for the connection and to check which standards it can use.

How can I check that ?

EDIT

Alright, I have tried sudo lshw -class network and I got from that :

So I can get form that my card's 'possibilities' wireless=IEEE 802.11bgn

but how can I get information about current connection ?

I have a serious problem with Xorg server on ubuntu 12.04 (with nvidia 420M GT card).

At home I am using an external monitor connected to my laptop's HDMI port - the external display is used as extended. But then when I leave my house and go e.g. to work I don't use it anymore but my xorg's config file remains as it was and then some bad things happen. For instance - every time when I boot after disconnecting the external monitor I get some not default font and bigger than usual + some windows with errors about not compatible resolution modes.

But today I have tried to boot normally without the additional monitor and xorg server has failed and I cannot boot to GUI. I am receiving this

I have also received error that screens have been detected but none of them has a proper configuration file but then I have tried to reset xorg to its defaults (in failsafe mode) with

sudo dpkg-reconfigure xserver-xorg

(I got no output form that ) and now I am stuck with this. To be honest - I have this error while trying to log on to failsafe mode and get the ubuntu splash image when trying to boot normally.

Here is my config file xorg.conf:

I would like to stop Ubuntu from mounting my other (Windows) partitions automatically since I do not need it very often, I would like not to automount "System reserved" partition for Windows.

There is a similar question here:

How can I stop Ubuntu 12.04 from mounting Fedora 16's Swap Partition?

However, I do not have these partitions added in /etc/fstab.

How can I do it ?

For proof, my /etc/fstab:

proc            /proc           proc    nodev,noexec,nosuid          0   0
# / was on /dev/sda7 during installation
UUID=1384cee0-6a71-4b83-b0d3-1338db925168 / ext4  errors=remount-ro  0   1
# swap was on /dev/sda6 during installation
UUID=e3729117-b936-4c1d-9883-aee73dab6729 none swap    sw            0   0
#------ MY WINDOWS D DRIVE---------- I WANT TO KEEP IT

I have just came across something that is really bothering me. Autocompletion on ubuntu works like a charm but when I login as root, e.g. su I get tab autocompletion only sometimes.

Why does it work like that? Can one change that?

I'm trying to create a file in /var/www, but even with sudo this fails:

When I use sudo nano, I can save something to this file.

Why can't I use sudo echo?

Does anyone else encounter problem with Clementine's keyboard shortcuts not working ?

I have them assigned to

but they do not work. Although for instance the shortcut to open preferences in Clementine Ctrl+P works.

Any ideas/solutions ?

I am trying to improve my command line skills and I have encountered a problem where I cannot kill a process. I type kill 2200 where 2200 is my PID and the process is not killed. After few minutes wait is still in the top and ps aux. I have even tried typing it with sudo - no results.

Any ideas why it would be like that ?

EDIT

I have found a weird dependency, where fg updates the processes list:

I would like to know what is the difference between

• su -
• sudo bash
• sudo sh

I cannot login as root while doing su - because I do not have the root password - I mean I have my user password with which I can sudo "command" but this password does not work for su - I can log in as root with sudo bash with my user password and I can login while doing sudo sh but then I get a command prompt in this form #

As in the topic: I would like to remove files in a directory that have been modified in a particular date range. How can I do this ?
