Fedora Hardware :: F12 Video Corruption - Horizontal Wavy-ness - Screen Looks Almost As If It's Underwater
Feb 27, 2010
I've just installed F12 and during boot and at the desktop, the screen has an issue. I have a 9700 pro and the resolution gets detected properly (1440x900), but it's like the frequency is slightly off. I see the screen fine, but the screen looks almost as if it's underwater. My monitor accepts two freq at 1440x900, and the issue is at the 60Hz setting. If I change it to 75Hz, the screen is fine, but the corruption is still there during boot and at the login screen. Ubuntu 8.04, 9.10 and Mint 8 all work just fine at 60Hz. This is using the default driver for my ATI card. The corruption was there in anaconda when I was installing F12, but figured it would not be there after the install. Can I somehow force 75Hz to the kernel mode set? I'll try to get a video up on ..... soon as it can describe my problem perfectly without words.
I am doing a new install of i86_64 on a system with a wide 22" monitor. The initial screen displays fine but after selecting "new install" the monitor becomes alternating black and white horizontal bands. the cursor is visible and tracks the mouse. The monitor is an Acer with fixed 37kHz horiz x 60 Hz vert. I assume that the gui is using a fixed (and different ) set of frequencies and is not plug-n-play. I just finished an i386 32 bit installation on another machine which went without a hitch.
I got macbook pro 5.1 recently upgraded to 11.04, all works out of the box! However when I watch movies or play a game from time to time I observe a horizontal line in the upper part of my screen which I believe is a screen tearing.Depending on a movie player this effect is more or less visible.nvidia propietary driver enabledvsync enabledcompiz settings adjusted (refresh rate ->60, vsync)nvidia-settings -l is loaded with the systemMaybe it's not a huge problem but everything works fine under osx
I've got an older graphics card I'm trying to use. It actually runs fine through the bios and even works when fedora is loading. But once fedora finishes loading half the screen turns into thousands of multicolored horizontal lines.
I'm having a problem watching TV on Ubuntu. The video has horizontal lines where there are motions on the video:
Do you know how to get rid of that? I'm using Me TV, and I selected all different deinterlacing types: None | Standard | tvtime but I didn't see any difference.
I'm having video issues with my graphic card while using Ubuntu 10.04 LTS 32 bits. When I'm watching video (Either on ....., or a dvd or whatever) There are horizontal lines cutting the video, like when there's very fast movement it doesn't render the video smoothly and so I get to see like vertical divisions, I don't know how to explain it exactly. I have a driver installed, one that installed automatically when I turned normal effects on, but I don't even know which one it is, I'm very new to this.
I'm experiencing occasional flickering of horizontal lines during DVD playback. Another thread suggested turning off the de-interlacing but it is already turned off and turning it on doesn't change anything.
I have an AMD 64x2 4200+ with 3GB RAM running Ubuntu 9.10 64 with on board nVidia 6150SE video. It doesn't seem to matter which player I use (MPlayer, Movie Player, VLC, etc.), so I'm wondering if it may be some sort of video configuration problem.
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 have a HP Compaq nx9010 laptop with 1 gig of memory and 128mb being dedicated to video memory. The graphics chip is ATI Radeon IGP 345M.
I can only set my resolution to 1024 X768. If I try to change it to any other size or try to play any games, the video has millions of jerky horizontal lines going through it. If I hookup an external monitor the video works just fine. Being new to linux and even newer to installing on it laptops, can anyone tell me what if any thing can be done to correct this. I am running Ubuntu 10.4 LTS.
Everytime I boot up and get to the log in screen there are these horizontal bars across my screen how do I fix this? Is it my graphjcs card or something because I got an older hp pavilion laptop thats about 4 years old and is there a way to get these bars off my screen so I can see my laptop more clear?
It started many months ago on wheezy. Occationally I got horizontal stripes on my screen when I used my system for many hours switching from one application to an other. Now, after I installed Jessie this problem hasn't gone away, but got worse. Now I don't need to use my system for hours before I encounter this effect. Different parts of my screen get unreadable without any predictable pattern.
Friens of mine argued this might happen because of a broken RAM chip. I bought my Acer Extensa 5220 in 2008. I'm not sure if it's worth to search for new RAM fitting into this old notebook.
I just got the new kernel update (2.6.32-24-generic, according to "uname -r"), and I went to restart my computer as the system requested. When I selected the new kernel from the boot menu, the Ubuntu splash screen came up, and then it did this subtle alternating shades of purple horizontal line thing. Then a vertical line appeared towards the right of the screen, and then everything faded into this cloudy, bright white splotchy...thing.
The keyboard was still responsive, and hitting ctrl+alt+delete restarted the machine, at which point I tried to replicate the problem, but everything loaded normally this time. My questions are: What the heck happened? Why? Is it dangerous? Why or why not? My machine is a Dell Inspiron 1501, 2 GB RAM, 120 GB hard drive, ATI integrated graphics, AMD 64 Anthlon X2 processor. I'm dual booting with Windows 7 as I learn Linux.
I'm getting some weird corruption on the screen in openSUSE 11.4 or Ubuntu Natty and wondered if anyone has seen this or could offer some suggestions. My config: Athlon XP 2400+, ATI Radeon 9800 Pro 128MB (R350NH), 1GB RAM, fresh install of either OS. It manifests as evenly spaced columns of discolored pixels, which change as different windows are drawn on the screen. At first I tried compiling the latest radeon drivers from git, but that didn't help. I've also tried nomodeset, x11failsafe, turning off desktop effects, turning off dri/dri2, and nothing seems to help. The corruption appears even if I switch to the vesa driver or fbdev. Any suggestions? This has got me stumped.

Once I select Ubuntu 9.10 from Grub, it shows the logo, the logo disappears, a jet black screen shows with 2 horizontal white dashes appear at the top.
I recently uninstalled Firefox 3.6 pre using synaptic to go with the stable Firefox 3.6 installed with the PPA repository that was given in the Ubuntu wiki. It installed and ran fine but when I rebooted, ubuntu wouldn't start.
I went into recovery mode a few times, tried to fix any broken packages and when it said it was fixed, I tried rebooting and the same error occurred. I also tried to use dpkg-reconfigure for the xserver-xorg and then ran startx but x didn't load properly. Some more debugging and a few driver errors came up involving intel so I installed a package which fixed that.
Ran the dpkg-reconfigure again and ran startx. This time x loaded but it was a jet black screen and I had to hold ctrl + alt and hit a few F keys to get back to the prompt.
I understand this could be a xulrunner error so I tried reinstalling xulrunner-1.9.1. I also rolled back my repositories to get the Firefox 3.5 branch and I installed the original Firefox 3.5, ran firefox --version to make sure and I finally have that back installed.
I tried rebooting and running the OS normally, but again it failed at the same point. What exactly should I do next? Yes, I could reinstall but it's such a small problem with maybe 1 or 2 broken packages, is there anyway I can save my current ubuntu system (as I have made countless configuration changes months ago and I do not want to do it again)?
This is my third SLackware install. I installed 10,12, now 13. the Xorgsetup has changed I think, it does not display the screen to choose Horizontal and Vertical settings for the monitor. In addition, how can I set the Refresh rate?
I didn't really notice this problem until I started using my Linux Mint Laptop (Acer Aspire 5672 WLMi) to develop some software but when I look at my screen really closely there appears to be wavy horizontal lines constantly running up and down the screen.
This is a default Linux Mint machine so I'm thinking that perhaps I need to install a proper ATI video driver?
Here is some detail of the graphics adapter:
Code:
I'm looking through the Xorg logs (/var/log/xorg.0.log) and it looks like the OS is loading ATI drivers but I'm not quite sure if I'm seeing this correctly?
Code:
I'm not really sure what to do at this point. These wavy lines are getting irritating but I don't want to spin off in another direction and break my display all together if I dork something up.
From a distance the screen looks great but upon close inspection there are subtle horizontal lines constantly moving from the bottom to the top of the screen.
I have lately been doing some planning to make a small embedded device (using uClinux) and got to the point of researching storage. I was contemplating using a removable card for the whole storage, but I can't seem to find too much information about the free-ness of various portable storage (there's a brief bit about SD cards on the wiki page, but it's not abundantly clear to me). Can anyone speak to the openness of CF, SD, SDHC, etc.? Are there any OTHER cards out there that are more open, and preferable to use? Aside from being supported, I'm hoping to use something that isn't "on its way out" (so I can get replacements if I have to), but I still would love to stick to my ideology and pick something that is made with more of a free attitude.
anyone seeing Firefox (version 6 and 7)screen corruption using the ATI binary blob with hardware acceleration enabled ? N.B Works fine when hardware acceleration is disabled.
I am new to linux but will try and be as precise as I can. I have a Dell Insp. 1545 with 3GB ram with 10.04_64
Problem: Rather out of the blue upon login, from the time of entering password to the desktop, is MUCH slower. I have no splash enabled and there is some reference to AppArmour profiles (it sits there at this apparmour reference , then sits trying to load desktop). However, I have never configured apparmor. Finally, on last login, there was some sort of screen corruption prior to getting to desktop.
Prior to all this i noticed that firefox "blinked" when I was using it, and then said that it needed to shutdown/restart for updates. I did notice at that time two of my previous tabs sortof acted oddly (moved around then disappeared).
I have no SSH/Server software etc activated.
I did change visudo so that sudo timeout shorter than it was. However that is the only modification to the system recently.
I have no experience with embedded systems hardware and am looking to build a micro-budget underwater robot for exploring the bottom of a lake on the family homestead. I don't have much money to spend on this, but I want to run Debian Linux (I have lots of Linux Admin experience and am right at home with a terminal) or something like that on a small chip which needs to be able to:
Connect to the control computer via ethernet. Get digital or analog data from a GPS module, pressure sensor, etc. Control a few thrusters. Do various other hardware IO functions. Possibly control a robotic arm (this is a long shot, I know). And costs less than about 100 dollars. I have no experience with embedded systems hardware so I really don't know what to buy or where to start, aside from the fact that I heard that this would be a good place for something ARM-related. I am a software developer with time to burn as far as writing the programs to support this goes.
I've been having these weird problem with sound after the last few updates. The background music of a ..... video or audio CD playback would be fine, but any vocal/commentary track that contains human voice would be all jumbed up and sounds like you are listening to it from underwater. The volume for the human voice part of the audio would also be a lot lower than the music track.
Not sure what the problem is, and the only way of solving it was through system restore (which actually takes more time than a reinstall). The test sound in YAST sounds fine (well, it's a music track afterall), and most instrumental music on ..... seems to play correctly.
I have weird graphical glitches in Gnome 3. They appeared in RC3 and now appear in the final release, but they didn't appear in beta. Here's what they look like, there are horizontal white lines appearing in different places where they shouldn't appear:

it can be a result of this bug:[URL] but my glitches look different than the ones in there.
I have a Mobility Radeon HD 5650 video card. Should I just update my system regularly and hope it gets fixed, or is there some way to fix it by tweaking some settings or stuff? Maybe by installing the official ATI drivers? I'm not sure, but I've read somewhere that the official drivers don't work well with Gnome 3, is that true?
When zooming in on some websites there is no horizontal scroll bar and therefore you can't scroll over to see the rest of the webpage? Fedora 15, Gnome Shell and Firefox 4 & 5 & Nightly builds version 64bit. On this site for example [URL]. 30 views and no one has clicked the link and tested it in firefox?
I open a new thread for ask you some help about a graphical problem concerning my graphic card under gnome3. My laptop is an Acer Aspire 5738zg and my graphic card is an ATI mobility radeon Hd 4570. I'm under gnome 3 and just made a recent installation in 64 bits from the DVD . I'm running with the free driver.I just got an horizontal artifact in the application list , here comes the screenshot URL...
I tried to find some help in french forum , but nobody have any ideas and the problem is reported on a bugzilla but those days , there was no answer or following on this subject. I give you the link too URL...I did a glxgears too and i can say you i'm running at 60fps so everything seems okay with the vertical synchro.
After having used fc5 for years, I installed fc10 in order to be able to run the newest versions of some of my tools. Under fc5, my monitor (Dell 2407FPW) and adapter (ATI Technologies Inc RV380) have happily coexisted at 1920x1200 76Hz. During the fc10 install, the monitor flickered a few times, then settled down (an auto-detect by the installation?) Now, after installation is complete, if I display a window with a lot of small text, the text is nearly unreadable because of horizontal jitter. If I move the window part-way off-screen, so that there is less small text on-screen, the jitter is somewhat reduced.
My hunch was that the installation got the ModeLine settings wrong, but when I went to edit /etc/X11/xorg.conf, I couldn't find it. I also ran a case-insensitive search for any file containing "ModeLine", starting in /etc, but nothing turned up except /etc/prelink.cache, a binary file.
I tried running Computer/SystemSettings/Display, but every time I do this, the monitor immediately goes into sleep mode, and nothing will recover it out except an X11 reboot (Ctrl-Alt-Backspace).
Is there any way to tweak the display settings other than the gui ("Display") program?
Last night I was working on a document on my brothers Laptop computer. While working on it however, the computer locked up hard and I had to press the power button. When I booted back up I loaded up OpenOffice.org and it offered to recover my progress as normal, so I gave it the go ahead but it gave me a blank page. No big deal, I thought, and went to load up the original document. That is when the *beep* hit the fan. The original document was corrupted. My theory was that it was saving at the time of the crash. A 50 KB document now reads as only 4 KB. I did have a backup of the document from about a month ago, but that is ten pages shorter than the document that I lost.
Is there anyway I can recover my progress on the document? The computer is my brothers Dell Latitude D600 running Fedora 12 and he is using OpenOffice.org 3. I checked the "~/.openoffice.org/3/user/backup" directory and found two documents, but those are just useless files from when we were doing Grade 10 Social Studies. I doubt the remains of the file are much use, as it has shrunk in size dramatically. So it seems I may be up a certain creek, but I thought I would ask a few of the guru's here for some advice.
I did learn how to make it automatically backup files in OpenOffice.org through. Hopefully that will help prevent these kinds of situations from occurring again.
I have a problem, my filesystem seems to show random corruption. For example:
[Code]....
This has happened to many files, they suddenly contain random garbage. Fsck seems to say the filesystem contains no errors I tried to run it multiple times.
This is a strange problem, 2 Fedora 11 machines, both Dell's. On machine A, remote desktop is okay. On Machine B, remote desktop display is corrupt/unusable.
However, prior to upgrading to Fedora 11, both machines had Fedora 10, and, remote desktop on Machine A was corrupt and Machine B was okay.
Any idea what happened? Why did the upgrade fix one and break the other? Both machines where upgraded with Pre-upgrade. The two machines are in to separate locations, un-related to each other.
I installed fedora 12 on my system but had issues with the ATI card I had at the time which I could not solve. So, I bought a Geforce 6200 hoping that would help, but I am still getting issues. Firstly, I cannot play full screen Flash. I know this has been asked before but all of the solutions I have tried have failed. Also, I would like to know if it is possible to play AVI files, as I d/l a few.
If I cannot get these two issues sorted it will be back to the dreaded Mic...... As I said, I am a complete novice here, I tried to enable desktop effects, and a message came up saying I only had 2D support, so I am guessing a driver problem? I have not installed any new drivers, but did try to get from nvidia, that I could not get to install - it was a .run file.
I have just followed the four point installation guide that I found on here, and now when the PC boots I have a slow moving blue bar across the the bottom of the screen with 'Fedora 12' next to it, and the graphics are now totally shot, looking like something from windows 3.1!
