I am familiar with common video resolutions like 320x240, 640x480 and 720x480. Sometimes I want to use other video resolutions when encoding videos. Is there a formula to calculate the unknown value for the heightxwidth if one value is supplied? For example, if I want my video to be 480xWidth, what value should Width be to get proper aspect.
View 2 RepliesJust did a new install of 11.4 over top of my 11.3 and when I reboot into the OS it seems to boot just fine but the video is unreadable. When I boot into the failsafe the screen has a lot of gitter and the monitor tells me it's not in preferred mode of 1680x1050 at 60hz. All resolutions higher than 1280x1024 are unreadable. Tried booting nomodeset as I've read previous ... no luck. I'm still learning linux.
View 9 Replies View RelatedI've got Ubuntu 9.04 Jaunty + lxde. My video card is Nvidia FX 5200 (Nvidia driver ver. 173.14.18). My monitor is a lcd Acer mod. x193w (widescreen). At present I cannot choose the 1280x800 resolution as I was used to when I was using Ubuntu 8.04 Hardy. Nvidia X Server settings offers several resolutions (included the native monitor resolution, 1440x900) but not 1280x800 as before. I wonder why. I even added mode 1280x800 in the Section "Screen" of xorg.conf but it was ignored.
View 2 Replies View RelatedI have a problem with Plymouth. It works pretty well on low res, but on higher resolution some strange video artefacts appear - see attachments.
I use ATI proprietary drivers, if it has something to do with it.
The resolution is set in /etc/default/grub like this:
Code:
GRUB_GFXMODE=1024x768
GRUB_GFXPAYLOAD_LINUX=1024x768x32
edit: reducing colour depth doesn't help /end edit
I don't know whether it has anything to do with the current problem, but Plymouth used not to appear at all until I followed these instructions (or actually I took them from another thread but I can't find it at the moment and these are the same).
I don't know whether it's possible to take them during booting so I've taken these photos with a mobile and retouched in gimp to remove reflections (more or less), and since I'm no pro photographer nor photoshop/gimp master they look as they look. They should do to demonstrate the problem, though.
I have a csv file (id, loc, timestamp, impressions) that I need to derive some low-level calculations from. Im ok with basic sort and grep operations, but this one is challenging my feeble scripting skills (normally I�d throw it into a spreadsheet, but in this case Id like to ultimately create a script that I could automate). Ive already used cat/sort to order the csv file first on location and then timestamp so it looks like this:
Abt001, AA, 2009-01-01 10:51:00, 231
Cup002, AA, 2009-01-01 10:54:00, 3
Saf001, AB, 2009-01-01 10:51:00, 25
[code]....
What Id like to do is output to file a record of the total, min, and max number of impressions for each location. , e.g.
AA6504 3231
AB252525
AC37925109
ZZ35512341
how to do this and Im kind of stuck on how to approach it I think the combined steps of looping through the locations along with the min/max/sum calculations are throwing me. Eventually Id also like to do additional calculations like average, ect. but I think I can figure that out on my own if I can just get this part down.

I am looking for software (Windows or Linux) that can do the following: Resize one image to several provided sizes. Detects the type of the picture (wide, normal) and does the resize based on that. What I mean by that is that it should not break the image by shrinking it more in one direction then in the other so it looks weird. The purpose of this is my Blog. If I want to give my readers a wallpaper, I want to give them several options for the sizes so they can have it in their own preferred screen resolution. The image must however keep its original aspect ratio.

I'm looking for a Linux tool that allows me to transcode videos to a video codec that is highly compatible to the Windows platform. We produce large scientific videos from measurements and would like to show those videos during presentations and submit the videos to journals. We want to be as compatible as possible (we can not influence for example the codes installed on the presentation system or on the journal reviewers system).
Virtualdub suggests one of these codecs:
* Radius Cinepak
* Intel Indeo R3.2
* Microsoft Video 1
We tried ffmpeg, mencoder and Virtualdub under wine, none of those tools could produce videos encoded with the aforementioned codecs.
I installed Debian recently, and everything seems to be working fine, except some video games are unusually slow compared to what they would normally be. Tremulous, for example, worked reasonably fine on this computer with Windows XP, but now (Debian) for some reason it's laggy even on the title screen.
Something wrong with my video drivers?
All of the information I know:
The computer is a Dell Dimension 3000
RAM: 256mb? Gnome System Monitor says 247.1mb, SWAP: about 730mb
Processor: Intel Celeron 2.40GHz
HD: 25gb out of a 40gb HD free, and an external 1tb HD with about 920gb free

Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade: The package 'skype-common' is marked for removal but it is in the removal blacklist.
This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
This is most likely a transient problem, please try again later.
I tried again several times in different days and it is the same. I have 10.4 recently updated from my original installation of 9.10. I think it was not a pre-release, I did it automatically from the website and it took a long time. As far as I know, all I have installed is official, except perhaps Skype itself. There seems to be something connected with Skype. But I have exactly the same Skype I had with 9.10, where I updated every few days with no trouble. It is something peculiar in 10.4

I use a 17" laptop with a 22" secondary monitor running Ubuntu 10.04 LTS. The res on the laptop screen is 1440x900 (16:10) and the secondary monitor mirrors this. Problem is that because the secondary monitor aspect ratio the display is somewhat distorted. It's not so bad that it is unreadable but I work in IT so I am at my computer for around 8hours a day so it wear thin after a while.
Is there a way for me to set different resolutions on each screen? The laptop have an ATI Radeon Graphics card and cannot change the Resolution above 1440x900 even within ATI Catlyst control center.
I'm running Kubuntu, OS Version: Linux 2.6.35-28 generic KDE SC Version: 4.5.8
I have a large monitor, and the max resolution of KDE (1280 x 1024) doesn't fill the screen. That seems rather small for a max resolution. Is it possible to get a larger one?
Under system > preferences > monitor I can select either 640 x 480 or 800 x 600 or 1024 x 768 which are all 4:3 aspect ratios, as my screen is 16:9 everything looks stretched. How can I set a 16:9 aspect ratio screen resolution?
