Fedora :: High Quality Screen Casts - Desktop Recording ?
Mar 18, 2009
I've noticed that there are a lot of different programs out there to record your desktop (screencast), and it can be tricky to understand the differences between them, their limitations, and how to use them, so i made a video where i show how to choose between them, what their features are, how to USE them, and how to get the highest quality video from them.
You can find it here: High Quality Screen Casts, Desktop Recording, with Linux

Does anyone know of any high-quality journaling software out there for F12KDE? I tried Keepnote, but it is not installing properly. Needs a Python(abi) dependency.

I am looking for a good mp3 player. I obviously dislike apple n windows so I wont buy an iPod or Zune player. Now I am wondering if any of you had good experience with any other mp3 player on Ubuntu. The two things I want are firstly a product of high quality n functionality like those two mentioned above AND secondly a seamless ubuntu compatibility. I'd love to see synchronization and stuff working out of the box. Anyone out there found a outstanding product and like to give a recommendation?

I am trying to split a PDF into component pages that are of equal quality to the original. If I use display mypdf.pdf, then the PDF is split into pages of acceptable quality. The problem here is that I have to save each page individually. If, however, I use convert mypdf.pdf mypdf.bmp, I get the individual pages of the PDF in .BMP format (which is fine, but not exactly what I want), but the quality is substantially less than the original. I've tried dozens of combinations of commands to try to increase this quality, but to no avail.
Even if I do convert mypdf.pdf mypdfagain.pdf, there is a big loss of quality. Anyone familiar with splitting a PDF into individual pages without suffering a loss in quality?
Ideally, I would just save all the "scenes/frames" from display, but that feature unfortunately does not exist (though I may endeavor myself to add it if no formal solution exists).
NOTE: I think part of my problem might be: by using identify mypdf.pdf I can see that the resolution is specified, and when I convert it the resolution is much lower. This could be a source of quality loss, but I'm not familiar enough with image conversion to say that for sure. Whatever this command does, it removes the extra layer or whatever it is that prevents OCR from succeeding. I'd really like to understand that technology.. What is it about a PDF that allows an individual to embed some meta-data into every page of the PDF so that the only thing seen, say, through OCR, or a text search function, is the embedded text?

My laptop is a Dell Inspiron 510m with onboard Intel 855 sound (STAC 9750 AC97). The sound was perfect with WinXP, but with Ubuntu it's tinny and lacks richness and vibrates and distorts at higher volumes. I've played around with Alsamixer and changed the driver from ALSA to OSS4 and it has improved slightly, but still not perfect. Is it just not gonna get any better, should I not be expecting it to be as good as WinXP?
I've seen on the Intel site a Linux driver for my controller, it's a tarball but it won't compile after extracting it (read on this forum that someone had the exact same problem with that driver). Will the Intel driver not help, does the problem go deeper than just the driver? It would be perfect it you could just wrap the Dell/Intel driver and use that (just like with wireless ndiswrapper).

I installed Fedora 12 on a new MacBook with a high def screen resolution (1680 * 1050) using Parallels. When Fedora runs, it run in a small window in the center of the screen - usable but far from desirable. Fedora 12 screen settings do not go as high as 1680 * 1050.

Spec:
Ubuntu 10.04 (lucid) 2.6.32-22-generic
ATi Raedon HD 2400 PRO (256mb) Graphics Card
3023 MiB Memory
Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz
Whenever I try running ANY screen recording program, my desktop runs too slow to use. I don't think this is a problem with my hardware capabilities, as I used to be able to record my screen perfectly in Windows, whilst doing multiple other tasks. I've installed the ATi/AMD proprietary FGLRX graphics driver.

I've been using Linux for a good six months now, and I'm loving it. I've recently upgraded from Ubuntu 9.10 to Ubuntu 10.04. When I was using 9.10, I couldn't use ANY screen recording software (Trust me, I tried a lot), as it made my desktop 'lag' so much but I just thought it was a problem with my OS, because when I was running Windows Seven I could record my desktop perfectly in HD, whilst running a lot of other applications.
My computer isn't exactly amazing spec, got a dual core 2.20ghz processor, and 256mb ATi Raedon graphic card.
Since recently upgrading to 10.04, I still can't record my desktop due to 'lag'.
Will this be a problem with my hardware? Is my computer just not powerful enough to record my desktop on Ubuntu? Or is another problem which I haven't even thought about?

I know that pressing ctrl+alt+shift+R enables me to record my screen, but I can't merge my voice with it. Is it limited to video recording without audio? If that's true, how can I merge two separate an audio file with video file (Gnome produces *.webm videos by default)

I can record my desktop for instructional aids but saying "And now click here" is not too cool and the user could miss the what-where. How do I have each mouse click play an audio sound or have a right click cause circular waves and a left click square waves around the mouse? Something graphic and/or audio. (My android tablet has the option of a click sound when a touch is recognized.)
I hope for something more obvious for the viewer. I don't use Compiz but would be willing to try it if that is the answer. Turning on Visual Effects (x) Extra does not do it. I didn't see anything in Assistive Technologies.

I want to do a screen capture with audio and video. I use Ubuntu 10.04 64-bit.I have now spend about half a day trying various tools, most of which seem to be half finished or abandoned. I have not found any usable docs for any of these.gtk-recordmydesktop and xvidcap will both capture video, but seem unable to capture audio from a microphone. The mic is connected and the sound preferences "input" tab shows the input level jumping up when I speak, so it must be working.
I tried the pulse audio device chooser app to make sure the mic is selected, but the choices for input are DEFAULT and "other", which shows a blank input with no choices.xvidcap multi-frame dialog has dev/dsp pre-selected as the input device, with no other options. It does not work.If I enable audio with gtk-recordmydesktop, it refuses to start and says it cannot open the sound card. There is no apparently no way to do this using the "advanced" dialog which has DEFAULT preselected as the audio input device and no other options. /dev/dsp also fails to start.I spent some time searching google and the forums here, to no avail. So should I give up trying to do this with Linux or is there some obscure method I only need to discover?I prefer xvidcap, since the ogg format output by recordmydesktop seems to be a write-only format.

I want to use 1920x1080 in the virtual consoles, with:
Debian Squeeze; proprierary ATI drivers.
Switching back to the open source drivers, it works automatically, but I got no clue with these ones. Someone say I should use uvesafb by modifing initramfs accordingly.

I know this is probably a stupid question , but I started using Ubuntu 11.04 .
My screen resolution on windows was 1600x900
But on ubuntu (even after installing proprietary drivers) the highest I can get is 1024x768 .
I tried using xandr but couldn't work it out .
My xandr info
When i tried adding a new mode using the command
I got the following error
Now I'm not sure what VGA refers to , but Im using a vga port to connect my monitor
Also I'm using only one monitor.

Is it even possible to ssh or Remote Desktop her computer with such a high ping rate? (average ping time is 300ms) If so why can I not connect?

The installation went okay (to start with) on my newly formatted hard drive (after death of Windows XP), but I got an error about 3/4 of the way through. The system said something about starting the desktop to try to resolve or fault find the problem. So I now have a desktop with access to all the menu system. I am feeling my way around slowly getting used to the environment. I think there are bits missing from the install but with no frame of reference I cannot tell what exactly is wrong. One obvious problem is my Monitor screen resolution. In Monitor preferences it is set as 'unknown monitor'.
The detect monitor button does nothing and the resolution is set as 2048 x 1536 which is just too small to see properly on the screen. I am currently using zoom to increase within a window to use at all. I have tried opening a terminal and using the xrandr command which reports the following:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 2048 x 1536, current 2048 x 1536, maximum 2048 x 1536.
default connected 2048x1536+0+0 0mm x 0mm

I'm running Ubuntu 9.10 on Athlon Barton 2600+ 2.2GHz, 1GB RAM and ATi Radeon X800 computer at 1600x1200 resolution with 2d (no compositing like Compiz).
Looking into the trouble of slow windows resizing I ended up with the observation that for 1280x1024 it's reasonably fast while at 1024x768 it's extremely fast. But 1600x1200 is my LCD's native resolution.
At 1600x1200 my computer is quite slowly responding, resizing windows or moving columns width makes it stumbling, you can see the action clearly does not go right with mouse, it's always late. KDE 4.x is way slower than Gnome.
I've tried many graphic cards (ATi, NVidia) with all possible drivers - open and proprietary, with or without 3d compositing.
Some graphic parameters:
GL_VERSION: 1.5 Mesa 7.6
GL_VENDOR: DRI R300 Project
GL_RENDERER: Mesa DRI R300 (R420 4A4A) 20090101 AGP 8x x86/MMX+/3DNow!+/SSE TCL
Glxgears gives ~4000fps with windowed mode and ~400fps at 1600x1200 maximized window. What is extremely amazing for me is that windowed mode takes 100% processor usage while 1600x200 maximized window (with window decorations) takes 30% of it, don't understand it.
Windows XP seems not to take care about 1600x1200 resolution, it's really fast.
Some more important devices from lspci:
$ lspci
00:00.0 Host bridge: nVidia Corporation nForce2 IGP2 (rev c1)
00:01.1 SMBus: nVidia Corporation nForce2 SMBus (MCP) (rev a2)
00:1e.0 PCI bridge: nVidia Corporation nForce2 AGP (rev c1)
02:00.0 VGA compatible controller: ATI Technologies Inc R420 JJ [Radeon X800SE]

I put together a little computer recently to hook to a TV.The problem I'm having is that when I start the computer up and get to the desktop... the desktop is off the edges of the screen. I checked the resolution and it's 1920x1080.I can't see the panels my applications menu, as they're both off the edge of the screen. Is there anything that can be done to correct this? Also, the TV has no settings to correct this problem.

I have installed Fedora 8 before 5 months. I normally use Eclipse, java, firefox, tomcat. Nowadays when I am working in any of the said applications suddenly my desktop goes off like a blank screen as if my monitor switched off. After 30 secs or sometime the user login page comes. I need to restart all my work again. I use gnome.

I am currently working on a large document using LATEX and have bumped into a problem. Here is the thing: I write this document in several machines, there is a Mac at school, some Ubuntu based machine, and this Fedora 12 x64 laptop. The thing is that I compile the document periodically on these machines and I WOULD expect the results to be similar, but they are not because the resulting PDF is of inferior quality! (fonts do not look very well when they are zoomed in).
Mac OSX's latex-produced-PDFs are of higher quality than their Linux counterparts. Is there something I can do to fix that? Install an extra package perhaps?
