Strae's questions

When you drag a file to the Unity launcher, only the applications that are supposed to open that file will remain active, while all others become deactivated.

Is it possible to configure Unity to ignore that setting and open the file, no matter what extension the file has, with any of the applications on the launcher?

I'd be glad to get an unsupported file type from the application when I make a mistake instead of losing a bunch of time configuring what application can open what file (that's because it is no longer possible to add a custom application/path in the Open with... menu)

In unity, we can drag files on application's button in the launcher to open that file with that application - however, looks like its hard to change default application.

I use Komodo as editor, and my goal is to open php files dragging on the Komodo button on the launcher.

The problem is that with gtk3 is a bit tricky to add custom application to open mimetypes..

I've created the button from the Main Menu, then i user mimeopen -d file.php to set komodo as default; Now, if i double-click on a php file, it get open with komodo - but I cant drag php files on komodo button on launcher.

I have a big (~250Mb) ppt file (created on windows i guess) with much text and some images (high definition).

I have to drop all images (i dont actually need to save them, just rip them out the presentation) from the ppt file: is there a way (via command line perhaps?) to automatically remove all of them?

Im trying to configure my Lucid 10.04.03 in order to work with Sip phones;

Actually, Ekiga and Jitsi* works fine, except for the call transfer/forward, that is very important for me.

With Ekiga, i press first H to hole, then T to transfer, then the number of a my colleague, but nothings happen.

With Jitsi, i get an "not implemented" error, lose the call and keep the sip account busy for about 30 seconds (strange thing is that jitsi should implement the transfer in the last stable version, but i tryed both the nighly and the stable)

Twinkle, Linphone, QuteCom; I've tryed them all but noone works with transfer/forward.

Any idea?

p.s: I'll love to get jitsi work becose it support even gtalk/jabber, so i can have 1 app to all my contacs.

UPDATE From the Twinkle manual:

When you want to transfer a standing call to another party you press the Xfer button. This will popup a dialog box from which you can choose what kind of call transfer you want.

Blind call transfer Transfer with consultation Transfer to other line

Call transfer will only work if your SIP provider and/or the remote party supports the proper SIP extensions.

this could be the reason why my xfer button is disabled, but my colleagues can transfer call without problem, they're using X-Lite on MacOsx, so i guess my sip does support call transfer...

my needs is to copy all files and folders of a "master" folder into all the usb keys mounted.

So, i wrote this code:

for usb_key in `ls /media/`;
    do
        for file in `ls -a /home/daniele/USB/MASTER`;
            do
                cp /home/daniele/USB/MASTER/"$file" /media/$usb_key/"$file"
            done;
    done;

for usb_key in `ls /media`;
    do
        umount /media/$usb_key
    done;
#alert me that the work is done
totem /home/daniele/USB/0016.mp3 &
exit

But, if i have a folder named "DO NOT DELETE" into /home/daniele/USB/MASTER, this throw an error becose of the filenames.

So, how can i do solve that? There is a way to replace all the whitespaces in the $file var with \?

Im looking for a game like Team Buddies (video), with online multiplayer mode for ubuntu.. possibly open-source.

Anyone know something similar?

Behavior:

me@local: tree
.
|-- ba
|   `-- file.txt
|-- foo
|   `-- file.txt -> ba/file.txt
`-- foobar

now, let's say i move the file.txt from ba to foobar:

me@local: mv ba/file.txt foobar/file.txt

I noticed that the symlink in foo folder still point the ba/file.txt path.

There is a way to create symlinks that auto-update the paths when the source file is moved?

Or symlinks that being deleted when i delete the source file?

Will be great.

When i was using windows, i used to run defrags, ccleaner and revouninstaller once a month to keep the system and the registry clean.

I know ubuntu (and all linux distro) has a different system structure and doesnt need defrags, but i've heard there are some mainenance tasks that help to keep the system clean (for example, sudo apt-get clean or sudo apt-get autoremove)

How many of those commands/software (and please explain what they do and if they can compromise the system stability) do you know and use regularly?

Just for curiosity, sometimes while installing software throught apt-get install software_name the terminal prompt me for a confirmation "type Yes or No", but not allways.

I dont mean the sudo password prompt, but the message "Will be downloaded and configrated XXX Kb, continue?" (or something similar)

Why?

Sometimes it happen that some application crash without give no output error (conky in my case, probably is one of my configuration that is incorrect).

Is there somewhere a error log that I can check to understand why it is crashed?

I know how to check hard disk integrity, and how to check RAM integrity (with live cd), but is there a way to check if others hardware is working well or is broken?

For example graphic card, audio card, etc.. ?

I'm not trying to check in an hardware works well with ubuntu (aka driver question), i need to check if an hardware is broken or not

Playing around with Terminal, I noticed that there are many ways to create permanent aliases.

I'm a Linux newbie, and from what I know, doing:

1. sudo ln -s /path/to/executable /usr/local/bin/desired_alias
2. adding desired_alias = '/path/to/executable' to ~/.bashrc

3. uncommenting those lines in ~/.bashrc:

   if [ -f ~/.bash_aliases ]; then
       . ~/.bash_aliases
   fi
   

   and putting desired_alias = '/path/to/executable' into the ~/.bash_aliases

all have the same effect.

What is the difference between the first and second methods?

Im using tilda on 2 computer, a desktop and a notebook, both with ubuntu LL 10.04 and Compiz.

The notebook has 6Gb RAM, 4 Cpu's (Core i3 330M) @ 2,13GHz, and an ATI Radeon HD 5650 (with ati closed drivers).. its a new notebook. The Desktop has 2 Cpu, 4Gb ram and an Intel graphic card.. its 5 years old.

I dont know why, but when i show/hide tilda (i use it in fullscreen mode with opacity), in the desktop show up instantly, instead in the notebook take 2~3 seconds.

Why the notebook is slower, even if it is more powerfull?

Can be a matter of drivers/graphic card type, or there is some configuration i can check?

On both I did install tilda from ubuntu software sources.

EDIT: I just noticed that it happens when i try to maximize every window (a terminal, google chrome, gedit, etc..), if i press F11 to maximize it: in the notebook it takes few seconds, in the desktop is instantly.

Could it be a compiz setting?

I have a Epson Stylus P50 usb printer and i need to print many copies (50~100) of some .prn files created via windows.

I cannot alter/convert those files; They need to be printed exactly as they are.

I installed the printer with cups and gutenprint drivers for epson R285 (there is not much difference between the 2 printer models).

My problem is that printing the prn with

lp -d printer_name -n 100 /path/to/file.prn

or

lpr -P printer_name -# 100 /path/to/file.prn

does not work as expected; Randomly the printer stops, in CUPS I got the error Unable to write 9640 bytes on printer_name and the jobs queue happens to be cleared automatically.

Sometimes, the printer prints 1~2 copies before stopping, but often it stops with the first copy.

I guess the problem is that Ubuntu expects the printer buffer is bigger than it actually is... but I really do not know.

So, is there a way to increase the printer buffer, or to lower the buffer that Ubuntu expects the printer to have?

Edit: the error happens even giving just 1 copy.
