idgar's questions

Yesterday I was copying things from NFS to my computer and something was stuck, after a while I tried to restart my computer but it didn't work so i force powered it off.

Now, when I booted the machine, it got to GRUB and after it couldn't boot.

It seems like vmlinuz and initrd loading successfully (no matter what version - 3.13, 3.11 i tried both of them).

all i see at the beginning is empty screen and after a while it sometimes tells me that mount points are not ready (/tmp /boot /):

"The disk drive for [some mountpoint] is not ready yet or not present. Continue to wait, or Press S to skip mounting or M for manual recovery".

except for "/", it warns about all the mountpoints in fstab.

Also can see that "rpcsec_gss daemon" is failed to start.

At one of my attempts it told me that there are serious problems with /, so I used livecd and fsck the disk. didn't find anything special.

My questions are: 1. how can I debug the boot process verbosely and find what cause this problem? 2. what can cause this trouble?

By the way, i have Ubuntu 14.04

Thanks in advance

just bought sound blaster X-Fi HD (USB) and i'm trying to understand what is the current output (sample rate and bit rate).

I've configured /etc/pulse/daemon.conf and set there the following values:

default-sample-rate = 96000 default-sample-format = s24le

How do i validate it?

I'm trying to understand how Gconf, Dconf and Gsettings works and what the relationship is between them.

All I know is:

• Gconf - XML based database (backend system). The older one.
• Dconf - BLOB based database (backend system). The newer one.
• Gsettings - CLI tool to edit settings. Looks like it works only with Dconf (although I saw somewhere that it might work with Gconf).

I know that for Gconf there is a GUI - Gconf-editor, and for Dconf - Dconf-editor.

So:

1. Which backend system is more often used - Dconf or Gconf?
2. Gsettings works with both of them? And why doesn't it show all Dconf schemas?
3. Where does Dconf save its data?

The first time I've connected my smartphone to Ubuntu, it asked me about the default action each time I'll connect it.

Now the default action is to open nautilus.

How do I change it to not do anything or ask me what to do?

I have an external drive connected to my computer, I want this drive to be in sleep mode unless i'm executing some backup tool.

For some reason, after 14 minutes I think, the hard drive always wakes up.

** edit **

i tried the following things:

1. btrace /dev/myexternal- to see which system call calls my external hard drive. unfortunately at the moment my hd wakes up I don't see any call.

2. fuser /dev/myexternal - to see which processes use this hd.

3. lsof - to see if there are files which has accessed.

4. mount the external drive manually to /mnt

5. stop lightdm and several processes/services.

How can I find which process wakes the hard drive?

I'm trying to install touchegg but for some reason it doesn't work.

For now all I tried:

1. sudo apt-get install touchegg
2. edit ~/.config/touchegg/touchegg.conf (What is the appropriate format? Plain text or XML?)

How do i make it work?

I went to keyboard application to set a shortcut for the home folder (set to ctrl+super+E as default) but for some reason it launches pcmanfm and not nautilus.

I tried several things such as edit files in /usr/share/applications or gksudo nautilus /usr/share/applications, but I can't find where is the setting that launches pcmanfm (at the files I can see Exec=nautilus %U).

i'm using Ubuntu 12.10.

Need a MP3 ID3 tagger, and cover fetcher

When I was using windows, I used to use Tag and Rename software for tagging MP3 files, which was really useful and convenient.

Do you have some recommendation to a software which is kind of similar to that?

My laptop has capabilities for 802.11n connections.

With my previous router, I could transer data faster than 54Mb/s. Now I have D-Link router and for some reason the maximum connection speed is 54Mb/s, which implies that the connection was established with 802.11g.

How can I check which standard (g or n) has been established? Is there any command to get that information? (nm-applet does not give any information about that in the connection information window).

I want to install some VNC server on my ubuntu 12.04. which one is the best / recommended? how do i configure it?

after i've tried to understand how syslog is working in ubuntu i found out that the package that exist is sysklogd (syslogd & klogd combination).

what I want to do is to get my router messages (which i've succeed in) but to a separate file. I saw that it is possible through rsyslog with ruleset.

how is it possible to do it by sysklogd?

Can you recommend a good modern GUI download manager (wget wrapper?)

I'm trying to find a good download manager that can open concurrent connections for a single download.

I don't mind whether it's an extension (I'm using chrome), or an independent application.

I have downloaded steadyflow, but it doesn't seems to have an concurrent connections option.

I want to work with GNOME 3.x instead of Unity 3D. I find it more comfortable but the only thing missing for me is that all of the indicators are now located at the bottom panel in contrast to Unity which locate them in the top panel.

How can I move them to the top panel?

i'm trying to change from runlevel 5 to runlevel 3 by running sudo init 3 command.

tried to run init 5 and then init 3 and still nothing.

does anybody knows how to fix it?
