Ubuntu :: Black Horizontal Lines On Desktop?
Aug 10, 2011
i have an dedll inspiron 8600 laptop. i just installed the new ubuntu, 11.0.4 i think. i installed from a usb. in the installation i wiped the whole drive with no partitions. i booted it while connected to the Internet and it loaded updates as it went. as far i know, everything went just as it was supposed to. the new os seems to be behaving just as it should.
however, (always a catch, right?) now, the right third of my screen appears to have thin black Phoenician blinds from top to bottom.
i can still partially see the icons in the top right corner, but not well enough to use them really, but they are active. i tried rebooting, but it didn't help.
i promised my girlfriend that this would make our dog poo machine run great and we could get more work done faster. i really hope i didn't make a mistake. the dog house gets me claustrophobic.

I have an HP Printer which prints black horizontal lines after each line or colors an entire blank line black, so a blank page will come out all black. Others who have access to the Printer are able to print well, without any problem.

I have an e-machines computer model EL1200-05w, I believe my Graphics card is a 6150SE, what happens is that often about 3 or 4 times a day my computer displays horizontal stripes and the computer freezes completely and have to shut down the computer manually, this does not happen on Windows and have tried Fedora and Kubuntu with no avail, I do not know if it's a Kernel Issue or the graphics card. I have searched extensively and have found nothing. I'm using Ubuntu Lucid Linx by the way.

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 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:
[URL[
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?

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've just done a clean install of 10.04.01 (64bit) and am having a few issues with the Nouveau driver.
1. I'm getting a series of horizontal lines across the screen ( image).
2. I'm getting, what appear to be, GPU lockups. This appears to happen after an amount of browsing and rendering images.
My system setup is:
10.04.01 LTS
grep 'Monitor name' /var/log/Xorg.0.log
(II) NOUVEAU(0): Monitor name: EA231WMi
VGA compatible controller: nVidia Corporation G71 [GeForce 7300 GS] (rev a1)

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.

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.

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)?

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 was wondering if in Gnome you can organize icons by Name/Type/View/Size and if you could organize them from Top to Bottom, Left to Right, etc?
Example:
Normally when you clean up icons they are organize in the following manner:
[X]
[X]
[X]
[X]
Left to Right, Top to Bottom organization would be like this:
[X] [X] [X] [X]
I prefer it this way and also KDE has it.

Operating System: Ubuntu 9.04
Printer: LaserJet CM1312 MFP
I have an intermittent printing issue that results in part of a printed page containing a horizontal line that spans over two lines. The line is mostly black, with the occasional small break where there seem to be printed multiple characters printed over each other.
Sometimes I print and I do not get this issue. Other times I can print 60+ pages and it happens, while sometimes I get it on a single page being printed.
I'm not sure if this is a driver, printer or cable issue. We've used it through CUPS and we've used a print hub to convert the USB to a network accessible printer to see if that made any difference but it did not.
I have a feeling this has something to do with the print job data corruption.

I wanted to get rid of ubuntu splash screen, and edited the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash text". Now it won't load at all. It nust shows the same purple background without ubuntu logo, then turns black and shows few lines of text. After displaying "Checking battery state... [OK]", it freezes and does not move further. I can't even.start a recovery mode because I have no dual boot and do not get this opfion at the start.

i just installed slackware 13.37 which worked fine but when i boot it up it runs a number of lines and then the screen just goes black... i can login as root blindly and start x (i THINK, judging from hdd led)... but screen stays black... its a laptop and closing/opening the lid doesnt work either...
i am dualbooting with slack 13.1 which runs fine... it switches screen res at some point during boot (font is smaller) and i would say that is the point where the screen goes black in 13.37...

I don't seem to have an "xorg.conf" file.
Gateway SB400a computer with Edubuntu Lucid installed. The problem first cropped up when I installed the Edubuntu packages on Ubuntu. I did a fresh install with Edubuntu and the problem persists. I don't want to go back to Ubuntu since this computer is for my Grandkids and I want to the Edubuntu stuff for them.
I don't have the specs handy, but I can get them. what I have to do to get them. (it happens when you get old)

Downloaded the F10 live CD. Booted to it, got past the white, blue, and dark blue loading bar then my screen would be covered in black and white lines. No sign of the GUI except for a mouse cursor. ctrl+alt+backspace would cause the display to blink off and then come back on to the same thing. ctrl+alt+f2 would bring me to a terminal, logged in as root, but from there I couldn't do anything. startx would tell me I had x running on another screen.
hitting tab when booting the livecd and adding "xdriver=vesa" and "nomodeset" to the boot line. That works. I get to the desktop at native res with desktop effects. Killer. I tried to install; install went flawless, rebooted to my HDD and the same issue, black and white bars. When booted to my HDD, however, ctrl+alt+f2 doesn't bring me to a terminal, it causes my monitor to go into sleep mode and my computer becomes unresponsive so I can't do anything from the command line.
Here's what I'm getting at : how do I get my installed version of F10 to do the "xdriver=vesa" and "nomodeset" args that the livecd can do?
My machine is a home built machine I bought off of a friend. P4 2.4 ghz, GB RAM, 2 80GB HDDs, Radeon x1600.

Ever since the problem with Flash started up a few days ago, (Videos Lagging/jumpy/jerky horridly.) I decided to finally switch from 9.10 to 10.04...all was going well until a few minutes ago while I was browsing themes and running Konversation, the skin flickered black/green a few times then white vertical lines started appearing down from the top of the screen to about the middle, (Almost looked like the teeth on a haircomb). I had to then shutdown and restart. What id like to know is are the two connected (My earlier flash problem and this) or how I can fix it, so far it hasn't happened again but I'm starting to worry, I've never had problems with Ubuntu until a few weeks ago.

I recently installed Ubuntu on my laptop and on my desktop i have two white lines on both sides. Ive been living with them there but after changing my theme ive really noticed them. Gnome-Panel covers up the lines, but they are still on the wallpaper.
Every wallpaper ive tried has had this problem, ive tried wallpapers with smaller resolution, same resoluton of my screen (1280x800) and larger ones.
I have a NVidia GeForce 8400 GS with drivers installed from jockey. Ive attached a screenshot.

The computer was working fine last night, when I woke up this morning (I leave it on) it was making strange noises through the speakers and I had a blank screen, restarted a few times had some page full of code and wouldn't move on from there, I went out came back started it up and it did everything normally except instead of a desktop I had a black screen, however strangely enough when I press the power button on the PC a shut down menu comes up, and the mouse works and I can select from the options. I am on an Nvidia ION tho. How do I boot into a safe mode as such? as at the moment I'm using a ubuntu live CD to read the forums!
On the GRUB menu, seclect "Ubuntu (recovery mode)" (not exact wording). You'll get scrolling boot messages until you get to a screen with a grey box and some options. Use the arrow keys to select "x failsafe graphics mode" or something of the like. Press enter and you'll probably get a message that your card can't be detected or something. Press okay and continue. Your screen will be messed up, but you'll be in. It probably isn't the same problem, as you don't have an ATI card and can see a shutdown menu, but good Luck!
How do you bring up the GRUB menu? My PC isnt dual booted so I never see any menus at all, I thought all I had to do was press F8 during boot up? No, F8 is Windows. Hold down shift when booting to see the menu. Downloaded & Installed the 10.6 driver and everything is working fine. Unminimizing apps works much faster with this driver . However, /usr/bin/aticonfig --initial results in
Code:
Found fglrx primary device section
Using /etc/X11/xorg.conf
Saved back-up to /etc/X11/xorg.conf.fglrx-2
/usr/bin/aticonfig: Writing to '/etc/X11/xorg.conf' failed. Bad file descriptor.
Right now I've tried what "jxtreme" suggested on quote nr2 however when I go into recovery mode I get a load of code scrolling through the screen as its supposed to but I never get any box with options as he says, it just gets to a point where there's a small white cursor flashing at me half way down the screen and it stays there...

I noticed yesterday, after what must have been the most recent updates, that my display now has a dark striped bar running down the right hand side of the display. It runs between the indicator applet and the deleted items bin on my standard Gnome desktop. I know it's not my monitor since I can see both of those items but maximised applications will not fill this area, even though the cursor is visible there.I've tried changing a number of display options but to no avail.
