isomorphismes's questions

In building ffmpeg from source, I got the following error to ./configure --with-libcelt:

ERROR: libcelt not found

So I went to http://www.celt-codec.org/downloads/, cloned the repo, and ./autogen.sh; ./configure; make; make install; make checked it.

Back to ffmpeg source directory, ./configure --with-libcelt again gave the same error.

I tried soft-linking /opt/celt/libcelt/celt.h into /usr/local/lib, but I am now officially stabbing in the dark.

I thought /usr/local/lib is the canonical place a ./configure package would look for a library, and that the main named .header file would be enough to show the configurator where things are. What's the right answer?

I opened a virtual console with Ctrl+Alt:F3 and now can't get back to the regular X display with Ctrl+Alt:F7.

The screen is black, the fan is going, the power is on. The light on my mouse doesn't come on when I plug the mouse in.

What should I do?

When I try to add http://www.newyorker.com/books’ podcast feed, I get this error:

There was a problem adding this podcast: The feed does not contain any downloadable items. Please verify the URL: http://www.newyorker.com/feed/books

Checking the feed, it looks fine....

My question seems a bit like How to add BBC podcasts to Rhythmbox?, but the answer there doesn't help me.

This is not a question about switching every one of my packages, or ubuntu-desktop (which I don't even use) to 64-bit.

I want to build just a couple programs in 64-bit. Is the answer different to the linked one above?

I have no idea what program caused this "Loading..." growl notification / bubble / shoutbox / popup

but it is still there outside of the web browser. (Even though it looks like a Javascript / web-browsy gif.)

I cannot xkill it. Is there another program I can use to identify elements that are drawn on the screen, and perhaps what pid to kill?

Under Keyboard Layout > Options > Caps Lock key behaviour one of the options is:

• Caps Lock toggles shift so all keys are affected.

I have that one selected (see screenshot), but when I do caps lock5caps lock, I still get 5 (not %).

Am I misunderstanding what this option is supposed to mean?

Unless I disable proxy, webpages show up as characters like

|ˆSš˜mð{ýîsqÐ|0MVà|ð|}}}0}@}P}`}p}€}P} }°}À}Ð}à}ð}~~ ~0~@~P~`~p~€~P~ ~°~À~Ð~à~€€ €0€@€P€`€p€€€P€ €°€À€Ð€à€ð€AA A0A@APA`ApA€APA A°AÀAÐAàAðA‚‚

or else as a .bin file available for download. For example https://dpaste.de/epVx is what http://stumblingandmumbling.typepad.com/stumbling_and_mumbling/2014/03/ex-growth.html looks like if I go through the system proxy.

If I use w3m through an ssh connection then webpages display fine. TTYtter works fine. vlc can even play the same youtube video at the same time as firefox can't load the site. I infer from this that those programs must use proxies differently.

Once I change the proxy from "system default" to "none" this problem goes away in Firefox. Aliasing w3m to w3m -no-proxy works for naked w3m but not in wrappers like surfraw. However, curl and by extension R still can't fetch data—and even sudo apt-get install is having problems.

I'm not even sure where the system default proxy settings are coming from. If I try to google about it I end up being directed to squid -- which I'm not sure is what I want.

The "context menus" which normally show up on right-click, as well as other pull-downs (for example evince's resize screen or any program's at-the-top menu pulldowns) are invisible.

This is Ubuntu 12.04.

I know the computer still thinks it's drawing them because of the way left-click responds. But I can't see its contents.

What program draws these?

Computer isn't playing audio. I've checked the hardware volume buttons, pavucontrol, and alsamixer. Nothing is muted. I've added the ppa sudo add-apt-repository ppa:ubuntu-audio-dev. I've also done killall pulseaudio.

However when I try mplayer I get:

[AO OSS] audio_setup: Can't open audio device /dev/dsp: No such file or directory

(which indeed does not show up with ls) and no sound comes out. Youtube via chromium also makes no sound; so does Vimeo; so does vlc.

What should I do?

I think this is the relevant bit of my ~/.bashrc file:

# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
    alias ls='ls --color=auto'
    #alias dir='dir --color=auto'
    #alias vdir='vdir --color=auto'

    alias grep='grep --color=auto'
    alias fgrep='fgrep --color=auto'
    alias egrep='egrep --color=auto'
fi

(I forget where I got this from so I sadly can't credit the source.) This is the only appearance of the line alias ls='ls --color=auto' in the ~/.bashrc file.

The annoyance is: Whenever I open a prompt/terminal/bash, the terminal echoes

alias ls='ls --color=auto'

(but not the others!) I would like to remove this notification.

Edit: Here are the other profile files I can find on the system.

#~/.bash_profile
#!/bin/bash
echo "You've got rhythm. You've got music. Anything else?"


#~/.profile
#unmask 022
if [ -n "$BASH_VERSION" ]; then
    if [ -f "$HOME/.bashrc" ]; then
        . "$HOME/.bashrc"
    fi
fi

if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi



#/etc/profile
if [ "$PS1" ]; then
  if [ "$BASH" ] && [ "$BASH" != "/bin/sh" ]; then
    # The file bash.bashrc already sets the default PS1.
    # PS1='\h:\w\$ '
    if [ -f /etc/bash.bashrc ]; then
      . /etc/bash.bashrc
    fi
  else
    if [ "`id -u`" -eq 0 ]; then
      PS1='# '
    else
      PS1='$ '
    fi
  fi
fi



if [ -d /etc/profile.d ]; then
  for i in /etc/profile.d/*.sh; do
    if [ -r $i ]; then
      . $i
    fi
  done
  unset i

The top -u mary command allows me to see all jobs running by user mary. What is the command to show the complement of that: all top processes except the jobs running by mary?

I've found helpful solutions to randr problems on the regular GUI (Ctrl+Alt+F7) but this question is about resizing the virtual console, which doesn't have good google results.

I've been using arandr to change VGA outputs between my 1680×1050 monitor and digital projector with I think a different ratio (definitely smaller numbers). Noticed a few quirky things like I need to resize VGA, then resize LVDS, then resize VGA again (possibly multiple repeats) to reduce the maximum screen size

Between going back and forth these two devices the most recent time I somehow reduced the resolution of the virtual console (Ctrl+Alt+F6) which I use most of the day.

The virtual console still shows up correctly on the LVDS but I'd like to change the VGA resolution so I can watch the virtual console on my monitor. It was projecting at a nice large resolution before my most recent switch to projector and back. (I even looked at the virtual console on the projector and it was large resolution.)

Any suggestions what I might need to do here? I tried xrandr --output VGA --mode 1680x1050 and got can't open display error.

Let me know if there's any other info I should give.

All of my google results on this question are about just learning to use synaptic.

I've noticed that Ubuntu's TTYtter package is quite a ways behind. TTYtter is just one file (one perl script) so even a newb like myself could update the Ubuntu repository without any complications of patching folders or .tar.gz's or the like.

So I think I can, and I'd like to, fix TTYtter to the more recent version. But how do I go about that?

I want to either extend the size of my guest partition or figure out how to copy stuff from the guest partition to my normal /home directory.

(Because of some other problems I can only run Xorg as guest, but I can log into virtual console as myself or root.)

Here's the motivation: I want to torrent a large file. It's larger than my guest filesystem. But I have plenty of space on my real drive, I just can't log into it graphically.

So I tried to set up a "pipe" to get the file out of the tmpfs. I did:

su -u myself 
#catch
mkdir ~/receiver_dir

sudo su
cd /tmp/guest-lkj567UIO/ 
#throw
ln -s mario_pipe /home/myself/receiver_dir
chown -R guest-lkj567UIO /home/myself/receiver_dir
chown -R guest-lkj567UIO /tmp/guest-lkj567UIO/mario_pipe
chmod -R a+rw /home/myself/receiver_dir
chmod -R a+rw /tmp/guest-lkj567UIO/mario_pipe

su -u guest-lkj567UIO
cd /tmp/guest-lkj567UIO
cd mario_pipe
touch something #success!

However, when I try to torrent to /tmp/guest-lkj567UIO/mario_pipe, Transmission says I don't have write permissions. But it looks like I just wrote there? And that everybody (a+rw) can write there in fact?

Maybe this indicates I don't actually understand chown and chmod but nothing from their man pages pops out.

Lately whilst browsing the web the mouse will "hold down left click" and not let go -- i.e. I get a closed hand icon that can move around but doesn't interact with the screen. Restarting the OS solves it but I don't want to to continually lose what I'm working on.

This is a problem with trackpad or USB mouse equally. From googling it looks like since Ubuntu 8 or earlier there has been a problem with Xorg whereby mouse errors in Firefox cause this problem.

The error was also noticed by this user: USB mouse moves but doesn't accept left clicks

I was able to solve the problem once by closing openbox and restarting with awesome but today that's not working. Any other ideas? Could I restart Xorg without losing everything and thereby "restart the mouse"?

All the information that google returns says to change ~/.gtkrc2.0-mine. Here is my .gtkrc-2.0:

# -- THEME AUTO-WRITTEN BY gtk-theme-switch2 DO NOT EDIT
include "/usr/share/themes/Dust/gtk-2.0/gtkrc"

include "/home/mars/.gtkrc-2.0.mine"

# -- THEME AUTO-WRITTEN BY gtk-theme-switch2 DO NOT EDIT

Here is my .gtkrc-2.0.mine:

style "default"
{
        GtkTextView::cursor_color       = "#ffffff"

        base[NORMAL]    = "#111111"
        base[ACTIVE]    = "#111181"
        base[SELECTED]  = "#808080"
        text[NORMAL]    = "#c0c0c0"
        text[ACTIVE]    = "#c0c0c0"
        text[SELECTED]  = "#111111"
}
class "GtkTextView" style "default"

Still appears with a white background!

I installed SAGE mathematics from binary because there was no package for it in synaptic. From reading on the web I learned that SAGE brings its own python libraries rather than using the ones Ubuntu / synaptic has already installed.

I'm getting low on hard disk space -- what can/should I delete? Or how should I rejigger my libraries / system to avoid duplicating ?(gigabytes) worth of libraries?

BTW, I'm having a similar problem with texlive-full -- I first downloaded the package in synaptic, then realised it was outdated, then downloaded the iso -- and now I think I have three or four copies of LaTeX on my drive.

I think I understand the instructions given in How to add a directory to the PATH? about adding directories to $PATH. But I don't understand how to add directories to $MANPATH or $INFOPATH.

Also -- in googling around for help I have noticed that sometimes directions say export PATH=/usr/share/lib/something:$PATH and sometimes they say export PATH=$PATH:/usr/share/lib/something. Which is it?

I use catdoc to preview Word documents from the command line. Is there something similar for HTML?

In other words I would like to do cathtml Webpage.html | less and get more or less a man page look output.

I want to run R in a virtual console and RCommander in a separate virtual console. Or maybe I want to run a game in a virtual console and shut off the desktop. Or maybe I want to pipe an ssh -x terminal to a virtual console.

How can I tell Virtual Console 3 to open a graphical virtual console in Virtual Console 9?
