Luke's questions

I have a set of audio files (WAV format) and a collection of data files and I want to create a mixed audio+data CD image (ISO) with (preferably only) command line tools.

I don't actually want to burn a CD, only create the ISO archive so that I can burn it later (I currently don't have access to a physical CD burner).

I have been searching around for tutorials and there is a lot of info regarding backing-up (i.e. ripping) but very little to creating images, let alone mixed audio+data images.

How can I create a mixed audio+data CD image with only command line tools?

I recently upgraded to Ubuntu 16.04 (XUbuntu) and I noticed that the behaviour of tmux has been altered.

I was previous on 14.04 where I was able to focus individual panes by clicking on them with the mouse. In 16.04 this no longer seems to work.

Furthermore, since the upgrade to 16.04, scrolling with the mouse wheel now seems to scroll through the previous terminal commands rather than scrolling up and down of the window pane contents.

This is my .tmux.conf (I prefer Ctrl+A over Ctrl+B):

# remap prefix to Control + a
set -g prefix C-a
# bind 'C-a C-a' to type 'C-a'
bind C-a send-prefix
unbind C-b

set -g mode-mouse on
set -g mouse-resize-pane on
set -g mouse-select-pane on
set -g mouse-select-window on

How can I bring back mouse click focus and pane content mouse wheel scrolling?

I'm running XUbuntu 14.04 and I have a AMD Radeon HD 5450 graphics card and two Dell UltraSharp U2415 24" displays (1920x1200) where one display is rotated to be portrait.

My system has never been super fast. It's a Intel(R) Core(TM) i7 CPU S860 @ 2.53GHz CPU with 32 gigs of RAM but it's been good so far (I'm not a gamer).

The other day I did a reboot because the mouse cursor on one of the displays was scrambled where as on the other it was fine (I never found the cause to this).

After the reboot, I noticed that my display rendering had become super slow. Dragging any window across the screen now results in a severe lag where before it was kinda slowish but not like this.

I started fiddling with my settings and I noticed that when I set my rotated display to "normal" the system is slightly faster. After some Googling I found out that the rotation is done by X11 and I assume this is happening in software.

I have removed and reinstalled drivers (a few times). I have manually sifted through my xorg.conf but nothing seems to really make a difference.

Is it just that my system is to slow or are there any optimisation steps that are available to me?

I have recently switched to XUbuntu (14.04) and I have noticed that sometimes a mouse click is fired twice.

E.g. I CTRL click a link and two tabs with the same content are opened in my browser. It's not behaviour I can reproduce consistently and seems to be random (to me). I also don't know of a good way to inspect the behaviour properly for debugging purposes. I have checked the double click time setting but this doesn't seem to have any impact on this.

I also run XUbuntu (13.10) in a VM on my MacBook Air and this behaviour seems to absent there. At this point in time I can't really tell if this is related to the distribution or the fact that it runs in a VM.

Any insights greatly appreciated.

I have recently installed the i3 tiling window manager [1] on my Ubuntu system and I'm trying to figure out how to copy & paste between various terminal and application windows.

How can this be done?

When I installed the latest version of Ubuntu with GNOME Shell, I saw it displays my name on the right-hand side of the top panel. I know my own name, I don't need to see it on screen all the time and besides, it takes up way to much space.

How do I remove my name from the GNOME Shell panel?

I'm trying to install Gearman on a clean out of the box 10.04 server using the following commands:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com
sudo apt-get update
sudo apt-get install gearman-job-server libgearman2 libgearman-dev uuid-dev php5-dev
sudo pecl install channel://pecl.php.net/gearman-0.7.0

I've added the following to my /etc/apt/sources.list:

deb http://ppa.launchpad.net/gearman-developers/ppa/ubuntu lucid main

But I get the following error after I run the apt-get install:

Reading package lists… Done
Building dependency tree
Reading state information… Done
uuid-dev is already the newest version.
php5-dev is already the newest version.
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:
gearman-job-server: Depends: libdrizzle1 (>= 2010.10.01) but it is not installable
E: Broken packages

Any help would be greatly appreciated.

UPDATE:

It seems I was able to install libdrizzle with the following instructions:

sudo apt-add-repository ppa:drizzle-developers/ppa
sudo apt-get update
sudo apt-get install libdrizzle1

After this I was able to install Gearman, however, I was unable to install the PECL module. The module seems to be no longer supported. I was able to install it like this:

wget http://pecl.php.net/get/gearman-0.7.0.tgz
tar -xvfz gearman-0.7.0.tgz
cd gearman-0.7.0
./configure
make
sudo make install

The default behavior of my shell window is to create tabs. I can switch between those tabs but only one tab can be visible at a time.

Is it possible to open multiple shells in the same window? E.g. have a window split 4-ways with each pane running it's own instance of a shell. I would prefer this over tabs since I can run my shell window full-screen at see 4 shells at the same time.

This has been going on for a while now. When there are new updates for Firefox add-ons and I start Firefox it's trying to download them but it fails. E.g. the first extension is Firebug. After a while I get a dialog:

Firefox could not install the file at 

http://releases.mozilla.org/pub/mozilla.org/addons/1843/firebug-1.6.0-fx.xpi

because: Download error
-228

How can I fix this?

I recently upgrade to Ubuntu 10.04 and I noticed that I'm no longer able to add a volume control to my desktop panels. When I right click the panel and choose "Add to panel" there is no longer a volume control in the list.

How do I add a volume control to my desktop panel?

During the week I did a update through the update manager and since then my desktop graphics have stopped working properly.

I usually just quickly glance through the list of packages to be updated before pressing install and this time I notice that a component called fglrx was going to be updated. I can only speculate that this has anything to do with it. I chose to update...

After the update I did a reboot and that's when the trouble began. My system was unable to boot into high resolution mode and gave me the option to boot into low graphics mode or reconfigure. I tried the reconfigure option but it didn't do anything and after I fiddled around a bit I was able to get back to a low-res desktop.

The first thing I tried was sudo dpkg-reconfigure xserver-xorg but this seem to do nothing. It just dropped me back to the command-line without a message.

Then I checked if my hardware drivers where still enabled so I opened System / Administration / Hardware Drivers panel and after searching for available drivers it came up with an empty list. I decided to downloaded the latest ATI x86_64 drivers and did an install of those. Installation was successful and I did a reboot.

I'm currently in high-res mode but I don't seem to have any hardware acceleration. Dragging a window around the desktop is a painful process to watch. There is an aticonfig command line utility that outputs about 50 zillion options. I'm pretty sure there used to be a graphical UI version of it but I can't seem to find it anywhere in my Applications menu.

When I issue the following command: fglrxinfo I get the following output:

X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  136 (GLX)
  Minor opcode of failed request:  19 (X_GLXQueryServerString)
  Serial number of failed request:  15
  Current serial number in output stream:  15

I'm on Ubuntu 9.10 and I have an ATI Radeon 5450 video card.

Any help would be greatly appreciated.
