Ubuntu Multimedia :: Video Out - Picture Flickering
May 12, 2011
I just installed Mythbuntu on my old laptop (lenovo with on board graphics card). I have now the problem that when I connect the TV out to my TV the picture is flickering. It looks like the image is sometimes jumping to the left or right for a fraction of a second. This usually happens when the image is not still, ie I scroll the menue or a movie is playing. I already tried different display settings but that didn't help.
I installed Ubuntu 10.10 recently and I love it. Everything works great except for video playing. When I try to play DVD's with VLC or ANY video player, I get horizontal flickering and I can't seem to fix it. I re-downloaded and installed the most recent video drivers from Nvidia and it did not change anything.
My video card:
Code:
I don't know what else to do. When I run windows, the videos play smoothly, just fine. But when I play the same DVD's under Ubuntu, it's choppy.
I am having problems: videos have sound, but no picture.I'm using a Gigabyte motherboard with integrated ATI video, and I've read before that XBMC (and Ubuntu in general) don't like ATI too much. Is there any hope left to make XBMC work?I've tried the following:1. Fresh Ubuntu installation, default ATI drivers. Result: when starting a video, audio is okay, but no video. Also, visibly slow graphics even while navigating XBMC menus
2. Installed ATI/AMD proprietary FGLRX driver via System->Hardware drivers. Result: significantly accelerated menu navigation, but no video still. Note: having no problems watching videos via VLC or Totem Movie Player (after downloading proper codecs)3. Fresh Ubuntu installation, then downloaded and installed ATI's proprietary Linux drivers from ATI's site (ati-driver-installer-10-7-x86.x86_64.run). Result: yippee, I see some video, but wait: no color!! (all videos are in sepia-like mode)
4. Followed these instructions to install the unofficial ATI drivers. Result: total failure, XBMC won't even start, says something about the need to have proper hardware OpenGL acceleration.System info:GIGABYTE GA-MA785GMT-UD2H AM3 AMD 785G mobo with ATI Radeon HD 4200 onboard graphicsAMD Phenom II X2 550 processor4 gigs of DDR3 RAM Ubuntu Lucid 32 bit (2.6.32-24-generic-pae)
I have 9.04 and I recently "got" a 13.2GB 1080p HD movie. When I try to play it, it's choppy and mosaic like. The audio plays fine, but the video jumps and I can't get a clean picture except for maybe 15% of the time. I have to hold down the spacebar so it plays and pauses very quickly for the video to even proceed. I've updates VLC and Movie Player and I've downloaded many codecs and I can't seem to fix it.EDIT: I can play it in Movie Player without the pixel/mosaic-like effect, but it too is extremely choppy.
I took a video of a tall object with the camera turned 90 deg. I now wish to edit the video to turn the picture to the horizontal. Is there a Linux application that will do this that runs in Suse?
I updated my system as usually. Sadly since then my screen flickers every 10 (or so) seconds. It turns black for like 10ms and then back to whatever it showed before. This behavior occurs after some uptime. Haven't measured the flicker-free time span yet but I guess it starts after 15 to 30 minutes.I'm using a up-to-date Squeeze with KDE4 an the nvidia-driver for me GeForceGo. Interesting thing is: It does not flicker while using fluxbox using same xserver.
i just fixed my old-ish laptop (pop accident) and instead of putting window on it my dad talked me into trying ubuntu out, gotta say love it, fast and everything but having major problems. i have a lenovo 3000 v200. everything is the same as out of the box except the keyboard, only thing i really needed to replace. ok problems
1) wireless is not working: i have the switch on (side of the laptop) and bluetooth lights up but wireless doesnt. (Intel PRO/Wireless 3945ABG). now i just learned about 'rfkill list' it shows that there is a soft block on the wireless. tried " rfkill unblock 0" nothing happened. also when i tried finding out wat kernel im using " uname-r" to find out more on why its not unblocking, the CLI says "comand isnt found" next two problems are small but are still frustrating
2) built in camera: the green light is on next to the lens but when trying to test the camera on skype or a photo program the video feed/ picture is black, or blank. not sure what i can do to fix that.
3) fingerprint scanner: yes i have one, i know its not efficient but I still like using it to login in instead of typing. im not sure how to get linux/ubuntu to recognize it if it even is. not sure how to set it up if it is recognized.
i would like to fix the wireless more than anything, if i can fix the camera and scanner then yeay, otherwise i can survive. oh and note i did try using the "additional drivers" app. nothing popped up.
I installed debian 7 with lightdm and MATE 1.8 (from backports) on a new PC.
Since the first day the mose keeps disappearing. For example when I click on something, the mouse disappears and only comes back when I move it. Sometimes it already disappears when hovering over a button (especially annoying when it happens while you try to resize a window).
That problem did not happen for example in LXDE, which I installed just to test that.
I did install MATE 1.8 on several laptops/PCs so far, never hat that problem. Maybe it's because of quite recent hardware?
I found a nice old mini industrial PC with an Jetway NF92 motherboard (Atom N270/Intel GMA945 GPU).
Installed Jessie on it, I have a strange problem under X11: mouse pointer is garbled (looks like somebody cut the arrow in four separate sprite and shake them well , and screen flickering. If I move down the mouse in the lower part of the screen, the screen flicker slowly, if the mouse goes in the top part of the screen, screen flicker rapidly... And finally, putting the pointer on the last line of the screen make the screen stop flickering with perfect screen....

i had just edited a picture in digikam that was going to be my new desktop wallpaper.when i went into system/preferences/appearance to make the new change it would not show the new picture that i had just edited as a choice to change my new wallpaper to. then i tried closing the appearance box and it would not close.then i shut down and restarted and when i bring up the appearance box it does not let me click on anything within.also can't close it.seems like other applications are working normally.
i installed kubuntu 9.04 yesterday and updated it with everything that was available, i have ati radeon xpress 1100 and i got everything running fine including kwin effects but i have a small problem i cant figure out how to fix:
When i run glxgears and put any window on top of it, i can still see the 3d gears rolling and i think this same problem is responsible for occasional artifacts on the screen. Its a very minor problem but i would like to see if fixed because i cannot use google earth properly, it seems that any 3d application likes to be focused on the screen, its like they flicker while being overlaid on top of everything.
Also i read the countless threads here complaining about not being able to use fglrx etc because of updated xorg. Well the reason im using 9.04 is because my wireless card alfa awus036h does not work with kernel > 2.6.31 and i have already tried kubuntu 9.10 on this laptop i wasnt having any problem with the display. All the kwin effects ran fine and no distortions of any kind. Seems there is some bug in 9.04.
When I hover over an open programme which is on the task bar I get a pop up, but instead of a picture of the actually programme I get a grey box like this
I'm converting my parents to ubuntu, so they stop complaining about how slow there windows installation is. I've only come to one problem now. my mom is in love with this Microsoft Picture It program, where she can fix red eyes, chance colors, contrast, tints, ect. Is there a program I can get for ubuntu thats very simple like Picture it? she is extremely computer illiterate, so the easier the better.
Cheese Webcam Booth used to work fine but now it just closes after I open it, Facebook wont load my webcam (but other websites can, and I wanna take a picture. I'm using a Logitech Webcam. I don't know what kind because it doesn't say anywhere on the stupid thing, but it has a spinny thing (to adjust the focus I think) that says "Right Sound" on it, and it also has a microphone.
So some videos works correctly played in VLC (1.1.9), but some doesn't.For instance I tried to play a VMW file (the video codec for that video in particular is : Windows Media Video VC1 (WVC1) ).The file plays with sound, but the picture is just black so no video picture. Now I have the regular codec package installed and in most cases everything works fine, but for instance this video doesn't and there have been similar cases in the past aswell.
my notebook has an external monitor connected with 1280x1024 pixels.
As long as the resolution of the external monitor is set to 1024x768 I can watch video with VLC, mplayer etc.
But once I set its resolution to 1280x1024 all mediaplayer play only sound. This happens on the external screen and on the built-in screen of the notebook. The desktop is extended to the external screen.
I just installed ubuntu 10.10 in a VM and went to change my desktop to something less boring and brown. I see in the desktop wallpaper program that there are certain photos that are in clusters (like you can click the photo and the next photo will come up and so forth). If I set my desktop to this cluster of sorts will it show me the photos sequentially or will it just stick to the first one. If not, is there a way to show this cluster sequentially in my background where it would change say, every minute or so?
I've been using ubuntu for several years now and one thing I've always have had problems with is getting a smooth picture when viewing videos. I currently have an amd dual core 2.2ghz processor and a H3200 ati graphics card which is more than capable of playing HD and blu ray perfectly in windows. I'm running ubuntu 9.10 with the latest graphics drivers 10.2. If I can movies etc., to play without lag etc., I can finally delete my windows partition. I want to avoid using a virtual machine for now.
I was trying to use Cheese today to take a picture using my built in web camera on my laptop. I am able to start the program and when it goes to take a picture, the program counts down and then quits.
When I run from the terminal the error I receive is:
I am looking for a program that would be able to recover some of my pictures. They seem to be corrupt. I know that there are several programs, really quite simple to use, to download from the web such as "Art Plus Digital Photo Recovery" and "PixRecovery". I was wondering if there are similar programs out there that can be installed on Ubuntu? Also, I have to mention it, when I try to open them with the "Image Viewer" an error message pops out which says : Could not load image 'picture.JPG'. Beneath that there is also this : Error interpreting JPEG image file (Improper call to JPEG library in state 200).
I have been using Tvtime for several years and never had trouble with the video until now. Now it opens, but it's frozen. There is no picture and no sound, just a black screen that I can't control in any way. Even to close it, I have to go through the terminal.I can still get channels using Mplayer, so the tuner should not be the problem. However, t is an Hauppauge 950.I was using Lucid on both partitions. Initially, one quit,but not the other. About a month later the other quit while I was watching which makes me think it may be something I have simply hit on the keyboard. I have since upgraded to Maverick on one and reinstalled Tvtime to no avail
I have the 64bit version of SuSe 11.2 installed on my PC. For some reason it cannot read a Jessops photo cd which reads ok on a windows pc or any other cd with photos on it, it has no problem reading other cds with program files on them.
Im using ubuntu 10.04 I would like to know if their is a program that can change the format, contrast, and brightness of a large bulk group of pictures instead of doing it one by one?
Noticed that gdm 3 updated to new version (2.30.5-1) which displays nice avatar for each user on the login prompt. Now there seems to be only placeholder pic for every user on this computer, but of course I want to have real picture there to greet the users. So the question is, where can I change the pictures?
