General :: Limit Video Output To A Section Of A Display And Leave The Rest Blank

Feb 22, 2011

The video projector I have to use this week projects an image too large for its screen and spills over on every side.

Fixing the physical setup is not possible or at least unlikely for the moment: the only solution is to carefully resize and position windows so that they display in the visible part of the screen - using full-screen mode is out.

Is there a way around this via software, using xrandr for example?

# xrandr doesn't have a padding option...xrandr --output VGA1 --mode 1360x768 --left-of LVDS1 --padding 200

Ubuntu :: Grub2 Manual Section Leads To Blank Display

Apr 3, 2010

Today, just hurry the boot process up a few seconds, I manually selected the kernel to boot to. Everything went well and got to the point where I heard the bootup sound and then the screen went blank and my monitor on-switch went orange - indicating nothing to display.

If I pressed the delete key I could hear the sound made when there's nothing more to delete. I switched to one of the virtual terminals and the monitor switch went green but no display.

I rebooted and let the bootup process as normal and everything was OK. I repeated the initial bootup process, with the manual selection, and it went blank again. The odd thing is, I'm sure I've recently done this before and all was fine.

Hardware :: Video Display Goes Blank When Switching From X To Virtual Console / Sort It?

Nov 9, 2010

I am having a problem getting my virtual console back after starting XWindows. The display goes blank when I press Ctrl-Alt-F1. If I press Ctrl-Alt-F7 I get the X session back. I have tried setting vga=x31A on the linux boot up. Also tried rdev -v /vmlinuz -1, and rebooted. I have tried two different monitors, same problem. One is a an LCD (Philips 170S6Fb/27, the other a Samsung Sync Master 750s. Originally the Samsung worked fine. I could switch between X and VC no problem. Now that I have the LCD monitor working after changing the XF86Config, I have this problem.

My kernel is 2.2.15-5.0, Redhat 6.2. Here is the output of lspci for the video card:

00:0c.0 VGA compatible controller: ATI Technologies Inc 3D Rage II+ 215GTB [Mach64 GTB] (rev 9a) (prog-if 00 [VGA])
Subsystem: ATI Technologies Inc: Unknown device 4755
Flags: bus master, stepping, medium devsel, latency 0
Memory at e2000000 (32-bit, prefetchable)
I/O ports at b400
Memory at e0000000 (32-bit, non-prefetchable)
Expansion ROM at 000c0000 [disabled]

Hopefully there is someway to control how linux sets the video mode when switching consoles.

Software :: Lock Keyboard (and Mouse) But Leave Display Visible?

Jan 10, 2010

I'd lie to leave the display intact and updating while locking the keyboard and mouse. Ideally, a password would unlock the keyboard but hot keys would work as well. Is there already software to do this? Or a Gnome "screen saver" that doesn't effect the monitor?

Ubuntu Multimedia :: Ffmpeg To Resample Audio But Leave Video Unchanged?

Mar 1, 2010

I'm trying to write a bash script for gpodder to automatically convert video podcasts to play on my media player. I'm using ffmpeg for the conversions (compiled myself with all codecs enabled). I'd like to avoid resampling the video or audio whenever it's unnecessary but ffmpeg seems to want to resample my video even if I only give it audio parameters to change.For example I have a test video with the following parameters:

Stream #0.0(eng): Video: h264, yuv420p, 640x480, 1394 kb/s, 29.97 fps, 29.97 tbr, 2997 tbn, 5994 tbc
Stream #0.1(eng): Audio: aac, 44100 Hz, stereo, s16, 159 kb/s

General :: Restrict Output To Display One File Each?

Jul 27, 2010

I use 'grep -Ri "mypattern" .' to search for all files in the current directory recursively that contain "mypattern". But this command returns every single occurence, so that if a given file has several occurences of the pattern, the screen fills up pretty quick. More than likely, there's a way to restrict the output so that it only displays each file once, no matter how many occurences it contains, but I couldn't find how to do it.

General :: Display Specific Block Of Contents Or Lines In Output?

Apr 23, 2010

Consider a situation in which you want to display only specific lines of contents from a file or of a command's output. Yes, we have head and tail commands. But, how to view all the lines of a file except the last one or vise versa when we don't know the count of lines in advance?

Consider this output:


[root@localhost ~]# ps au | grep bash
root 6316 0.0 0.0 4672 1440 tty1 Ss+ Apr22 0:02 -bash
root 20847 0.2 0.0 4672 1432 pts/0 Ss Apr23 0:12 -bash
root 21167 0.0 0.0 3920 660 pts/0 S+ 01:00 0:00 grep bash

Here, I don't want the last line (in italic) to be included in the result since the last line is due to "grep bash" in the devised command "ps au | grep bash". Well, we can rewrite the devised command:


"ps au | grep bash | head -n 2"

But, again, here we are specifying the count of lines to be included. But, in the presented problem we don't know any count in advance!

Ubuntu Multimedia :: Thinkpad A22m Video Driver - Mid Section Of Desktop Blurry?

Nov 14, 2010

I have a problem with the graphics on my thinkpad a22m laptop. specs:

900mhz cpu
256 ram
20gig hd
??ati rage mobility m3 video card ??

when I start up ubuntu (10.10) and reach the desktop, the screen is messed up. The center of the screen becomes blurry, and it looks like what is normally the right part of the screen is duplicated in the middle of the screen (with what should be the middle of the screen disappearing).

I think its an ATI video card, and I tried to install different driver from Softwarecenter but no succes.I know the screen is working, because when I boot forinstance, the Ibm logo is showed nicely across the screen. So its not a hardware issue. Another thing, I got puppy linux to work correctly after having the same grapphic issues on that OS when I first installed it. But some how I managed to get the right drivers. But as I like ubuntu more, I would appriciate your help with figuring this out

ps. when I try to setup screen resolution in System>Settings>"resolution", Ubuntu says "unknown display" (marked with red color).

Ubuntu :: Limit Pen Tablet To One Display Out Of Two?

Sep 9, 2010

I'm running a

Release 10.04(lucid)
Kernel Linux 2.6.32-24-generic
GNOME 2.30.2

Using NVIDIA Driver Version 195.36.24 with two monitors 1280x1024 each in TwinView configuration My Pen tablet is ID 5543:0005 UC-Logic Technology Corp. Genius MousePen 8x6 Tablet, Wizardpen driver (not sure how to lookup its version) The tablet is currently working just fine except for this one thing I'm trying to fix: it now covers the entire 2560 pixel width of the desktop and 1024 pixel height. Given that the tablet itself has a 4x3 side ratio, it results in its horizontal resolution being half of the vertical one. Basically, when you use it to draw anything you always have to mentally correct what you do by limiting your horizontal movements to only half of vertical ones which makes drawing a (relatively) straight line an impossible task.

So, this got me thinking that I want to make sure the tablet only works on one of the two displays - the one I'd open Gimp and Inkscape on - the only two programs I ever use the tablet with. However, when I look at the calibration settings of the tablet itself, it only allows me to limit the area of the tablet I want to be sensitive, not the area of display. I cannot find any such settings in NVIDIA X Server Settings either although I think this is where it might have been. So, does anyone know how to leave the same size of the tablet drawing area but make it move the cursor only on one particular monitor in TwinView configuration?

OpenSUSE Install :: Immutable Section Of HDD + Differencing Section?

Jul 8, 2010

You maybe know that VirtualBox has an "immutable" feature for HDD images. I.e. setup the system, if the stuff is in place, you can set the image to IMMUTABLE to prevent any changes to the image. Differences are written to a separated image. So on the next boot you'll see that all the (unintended) changes are gone and the "old" system is up & running again. I run an old SuSE 10.3 on a write-protected SD-IDE-Adapter. Changing and playing with RPMs is a mess due to around 50 changes I had to do to make that work. Is there any option to mount an SD-card as RO and having all the changes written to e.g. /dev/sda3? To make it clear: I thought about something like a RAID-X system, but could not find any description on how to setup a raidtab.

Programming :: .ogv Video Does Not Display With <video> Tag In Firefox 3.5?

Jul 3, 2009

I was trying to take advantage of that new HTML5 <video> tag, and Firefox 3.5's native Ogg support, by embedding an .ogv video. Here is the references I used:


Here was the code I put on my web page:


<video width="640" height="480" controls="controls">
<source src="http://path/to/uploaded/video/on/my/site.ogv" />
Your browser does not support the <code>video</code> element.

However, when I view it I get a video box, but it is grey and will not play a video. I keep playing with the various attributes but the result always seems to be the same. I also tried it on a Windows box with Firefox 3.5 (to make sure it didn't have something to do with my Linux config) but the results were the same.
