Ubuntu Multimedia :: Use The "filter All Layers" Function?
Feb 15, 2010
I installed the gimp-gap package from the repositories. When I attempt to use the "filter all layers" function I get multiple errors, and the plugins are not available to me.
Errors:
Code:
GIMP Message
Calling error for procedure 'gimp-procedural-db-proc-info':
Procedure 'plug-in-diffraction-Iterator' not found

I'm a n00b to both numpy and python. I was wondering what the most intelligent way to write the trapezoid rule function was:
Code:
>>> import numpy as np
>>> a=np.array([1,2,3,4,5])
>>> def mytrapz(vec):
total=0
for i in xrange(0,len(vec)-1):
total+=(vec[i]+vec[i+1])/2.0
return total
>>> mytrapz(a)12.0 This is exactly what I would do in C and I'm sure the for loop is not the fastest way (as is the case for my interpreted langs). Yes, I know there is already numpy.mytrapz... I'm interested in the most efficient way to loop over arrays in such a way that each iteration accesses more than one cell.

I add layers and they don't show up and the controls at the bottom of the layers palette (add layer, bin, etc) are all blanked out and i can't select them. It's impossible to do anything with layers in GIMP as it is at the moment and i need to get it sorted. I have tried closing down the layers tab, restarting GIMP and then adding the tab again but i get the same result, a layers palette that won't respond or show any layers that i do add.

I've got the OK from my manager to set this up, so I just need a little help. I've seen the tutorials on setting up VNC over SSH which works all fine and dandy, but I need access to my work PC when I'm not on the University Network. To log in to the command line I would have to ssh from putty to a central box that is visible to the outside network (i.e. the world) and from that box, I would have to ssh into my workstation.
Logical flow: SSH-Putty --> SSH-Midddleman --> Desktop-command line
How would I setup VNC to deal with the middleman?

OpenOffice 3.0 on Ubuntu 9.04
I have a card project in OpenOffice Draw. In this project is a bitmap with the year 2009 embedded in it. I want to change that to read 20 and I can place the current year as a text layer on top of it.
I have a grid laid out on this bitmap, and I have overlaid text information such as date, time and frequency.
I got hold of the bitmap and cut it, leaving my data there but the form behind it missing. I pasted that into gimp and did the editing, saved it as a .bmp file and loaded that into Draw. I copied the bitmap from this bmp file and pasted it back into my card project.
The bitmap is now sitting on top of my data and I want to send it to the rear so my data sits on top of it.
I can not find a single reference to how to send layers to the front or to the back in OpenOffice Draw.
Launchpad.net is a way to get help online, but I am completely lost on that site, so I am asking here on the Ubuntu forum.

I do a lot of artistic stuff, so I need a good graphics program. I think Gimp will be perfectly fine for my needs for the time being, but I can't find the layers box. When I opened it for the first time, only the toolbox and tool options were open, and I can't find anything about the layers. I checked the online manual, and that didn't help at all. I have version 2.6.

I want to know how a network packet travels through different layers, i.e. from the physical layer to the presentation layer in Linux systems.
Are there any detailed articles or books on this topic with code?

I mostly need it to filter away background noise from interviews. So, the editor should allow me to tweak the recordings in the frequency domain. I'm a Kubuntu user, so, if possible, propose me KDE apps!

For quite a few Ubuntu versions now, if I ever wanted to save a ..... clip, I just went to the file system's /tmp folder and did a cut'n'paste of the buffered file. Now I have upgraded to 10.04 it seems .flv's are no longer buffered in /tmp.
Where have they gone? Or is this function/ability 'no longer available' for some obscure and possibly political reason? I do get the feeling that, whatever the reason, this is a retrograde step not in keeping with the Ubuntu philosophy.

I bought a multifunction stylus sx218 Espon model and I can not run the scanner function. I did some research and found a few solutions and very functional. I hope someone solves the problem. My version of openSUSE 11.2.

I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

I have no sound after the Suspend function. I am running OSS4.I usually run "sudo soundoff && sudo soundon" after closing any applications using the sound... however, this is just a temporary solution. I suspend quite a lot, and so doing this over and over can get irritating.

I'm currently using OpenSuse 11.1 web server. This is bad since 11.1 is no longer supported. the reason why I am using it is because Function set_magic_quotes_runtime() was no longer being used. (so I was told)
That being said, is there a way to get Function set_magic_quotes_runtime() to function on the newer versions of OpenSuSE?

the function terminates if no key is pressed for 10 consecutive seconds. I tried using the -t option as suggested in some forums, but my version of showkey doesn't have the option of changing the timeout. The options I get are:
-h --helpdisplay this help text
-a --asciidisplay the decimal/octal/hex values of the keys
-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).
Is it possible to write a script to use this function and still keep the function active until an interrupt is recieved?

I have a Logitech K830 wireless 'Living Room' keyboard for general use under Debian/Gnome. The function keys (F1-F12) operate in conjunction with the FN key. Various multimedia options are alternately available by pressing the function keys (F1-F12) without the FN key.
I want to make the function keys primary (not requiring FN). 'xmodmap -e "keycode 172 = F11"' reassigns F11 as expected, but xev reveals multicode output for some keys that I cannot similarly remap. The (de-tabulated) table shows xev output for press-events. Single F(n) keycodes are followed by the equivalent multimedia keycodes (e.g. F2[+FN] key is also 'Minimize window'[without FN]).
KEY STATEKEYCODE KEYSYM
FN+F1 0x0167 0xffbe, F1
Adjust backlight ---- -- ------, --
FN+F2 0x1068 0xffbf, F2

I upgraded from Lenny to Squeeze.
I use Fluxbox as the window manager in X Window. I installed hibernate packages and gnome power management. I set the idle time at 30 minutes using the gnome power management program. It doesn't suspend at all. The monitor only shuts off during idle.
So, I logged in as root, started X. Without .xinitrc gnome desktop manager launched. As I clicked shutdown, it showed a dialog box asking hibernate / suspend / restart / etc. And then, I chose the [hibernate], the system shut down and came back to previous status when system restarted.
Which gnome program does control hibernate / suspend?
Is there anyway that I can control hibernate / suspend in command? I just need to make a little script and assign it to a launch key so that I can suspend the system when it's on idle.

My 785G motherboard comes with an integrated sound card. In the manual I see there is an option to install Dolby Software to make 2-channel stereo sources play to 4, 5.1, and 7.1. Is there any equivalent Dolby or other software for OpenSuse 11.2?

Is it possible to add a "play to" menu in the context menu in nautilus like in windows 7? For those of you who don't know what I'm talking about: When you right click a media file (avi/mp3/mkv etc) in windows 7, it lets you select "Play to" and then lists all upnp/dlna devices on the network, and the amazing thing is that when you select a device, the media file is actually played on that device! It would be so much easier to select a file and then "play to" my xbmc htpc, than to move the video to the htpc and then index it and then browse for it on the htpc and then remove it after I've seen it...
I couldn't find anything about a feature like that...? There must be someone else, beside me, that would love a feature like that? I know I can install ushare and stream that way, but the big difference is that the movie is started from my computer and not on the xbox, htpc, tv, av-reciever or what you use to watch movies over the network! It would make it so much easier! Setting up sharing, and then adding them to what you use for playback and then finally browse to your movie and selecting play is just not worth it when you know how much easier it can be done using "play to" for a few movies.

I am new to Ubuntu and would very much appreciate someone's assistance in getting my printer to work in the Ubuntu O.S.The printer filter is located in my /home/ldavis/opt... directory and not in the/opt/ OpenPrinting- Epson/ppds/Epson directory where some of the .ppd.gz are located and where the error message states it is looking for it. Do I need to extract the .ppd.gz in the /opt/OpenPrinting-Epson/ppds/Epson directory and install the filter in the same location?
After trying several times in vain, I attempted to download and install the pinter drivers using the sudo -i apt-get install <> and apt-get upgrade < >. It installed some Epson printer drivers, but I still get an error message that the printer is looking for a printer filter to be installed. Can someone please tell me how to install a printer filter and which directory should it be installed in?

I have a "Forward to" filter set up in Evolution. It halfway works. The emails I want forwarded are matched and put in my Outbox. The problem is that the emails are never sent. I have to manually click the "Send / Receive" button. If left alone, the emails will sit there over the weekend, never sending until I hit Send / Receive.

I need a command that will check the size (visual size, not file size) of every image in a folder and its sub folders, and make a copy (or even better, a hard link) of that file in a second directory if the image is larger than 1920x1080 pixels (in both dimensions, not just total area). Also, lots of these file names have spaces, so the command needs to be space-tolerant
I'm guessing I would need to use one of the imagemagick commands and find, but I'm not sure where to start. I'm still reading man pages, but I thought someone here might save me some time.
