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?
View 3 RepliesI get past the count down. The bars run across the top. Then my lcd monitor announces it has no signal and goes to sleep. Had this problem with earlier versions of Ubuntu, particularly 8.04. Was fixed in 8.10.
get Fedora 11 up and running?
I've been having trouble with rendering issues in Gnome for the past few weeks, running Sid on x86_64, Occasionally Blue and Grey horizontal bars show up, they go away partially if I scroll up or down, and the bars disappear completely if the window is resized. Select characters/letters will also occasionally become garbled, if I change the font in Gnome Tweak Tool it seems to temporarily fix the issue though.
View 5 Replies View RelatedI 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 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

It gets worse when I put my phone close to the screen (Motorola Razr V3v).
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.
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'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.

View 2 Replies View RelatedI'm still getting some vertical lines through my splash screen, they are just a little darker purple than the rest of the screen, but disappear over the ubuntu logo/text/dots. I've tried the following from the faq, which made the screen at least show up, which is wasn't doing before.
Bootup/Plymouth.
Users should experience a much faster boot however some users may experience problems with Plymouth after the nVidia graphics driver has been enabled. Users may experience plymouth using lower graphics resolution. [URL]
Graphical solution : [URL]
Command line :
(Some of the fixes put forward dont work for everyone.)
One that works for nVidia and to try is this.
Code:
gksu gedit /etc/default/grub
and add the line in BOLD.
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480
GRUB_GFXPAYLOAD_LINUX=1680x1050 Save the file and run
Code:
sudo update-grub
The resolution chosen should be your monitors native resolution.
Other graphics card users may get a black screen with flashing cursor and then a very short duration plymouth. [URL]. One fix for this is to create this file.
Code:
gksu gedit /etc/initramfs-tools/conf.d/splash
and add this option FRAMEBUFFER=y, save the file.
Then
Code:
sudo update-initramfs -u
After being on the computer for awhile, it suddenly stops and goes to the purple screen like one would see when turning the computer on, only slightly distorted. after a few moments it switches to a black screen with a flashing _ but you can't type anything, and then it changes so it's blank, and these white bars start to flash on the screen. I just put 10.04 on my computer about two days ago, it's been doing it since. When I first tried to upgrade from 9.10 I encountered a huge error of some sort so I just put a brand new install onto the computer from CD.

I am using a emachine w2925 desktop and I installed the newest ubuntu. And it randomly goes to a black screen with white bars vertically half way down the screen that flash between bars and a black screen every few seconds.

View 1 Replies View RelatedUbuntu 9.04 works fine, I have just installed Ubuntu 10.04 Lucid Lynx without problems, it runs fine but after a while the screen starts flashing and the only way out is to reboot with ctrl-alt-del. First of all I get a pale purple screen with blocks of random colour in the middle then it goes on to flashing between two screens. In one the top half of the screen is vertical black and white stripes and the bottom half is black, in the other it is a terminal screen with this distributed across it:
Starting common Unix printing system cupsed
Pulse Audio configured for per-user-sessions
Enabling additional executable binary formats binfmt support
Checking battery state
On the latest occasion the text was "could not write bytes: Broken pipe" repeated all over the screen, followed by "checking battery state".
I'm a little new to ubuntu. I installed a video driver and after restarting I got as far as the login screen where I saw that the driver did not work: screen is mostly black with random bars of color. I was only able to restart in recovery mode mode. I tried the fix graphics option, which did not work and also some commands that I've seen posted in other threads. So far, still cannot delete the problematic driver or boot up normally successfully.
View 1 Replies View Relatedi've got a mythbuntu 10.10 box connected to my tv; sometimes i want to use it to watch internet tv. owever, when i try to resize videos to full-screen, sometimes black bars intermittently flash across the entire screen. this does not happen when the video is in a window or on the web page, only when going into full-screen mode. unfortunately, on some of these sites, even the "large" in-page video selection is still too small to be comfortably watched from the couch.
i'd suspect it's something with flash, but a similar thing happens when i'm using skype inside a windows xp on vmware. black bars flashing across when in "full-screen" but just fine when zoomed up inside a window. and i don't think vmware video output is flash-based. so it may be something else entirely.
also, this doesn't happen on all internet video - i've only had it happen on video from nbc.com and nfl.com (i haven't really had the opportunity or reason to try many other sites yet), and it was only a little noticeable from the nfl.com but nearly unwatchable from nbc. yet if i go to videos, i have no trouble getting any of their videos running full-screen.
i have an integrated geforce 8200 graphics, and i'm running the nvidia proprietary drivers version 256. i'm not running 260 since its vdpau capability is questionable, and i need that for mythtv. i have a 64-bit system.
does anyone have any ideas regarding this? the fact that i'm getting consistently good results from videos yet consistently bad ones from the tv networks makes me wonder if it's something i'm even going to be able to fix.
I have searched online with no success. The brightness control is working fine on my laptop. Problem is that the bars don't get rendered on screen. Instead I get like a static white line on screen everytime I press the brightness control. On boot however, I can see the correct bars. It is once I start my xsession, the bars do not show up. Here are my specs:
Slackware 13
Xorg Radeon driver
kernel 2.6.29.8
My computer keeps having some kind of meltdown. i really cant explain it other than the screen will go black, and then it will start flashing like white bars, or different colored bars. this happens at such random times i cant exactly pinpoint what sets it off.
the only thing i may have a clue to is that in my update manager, there is one thing that is a distribution update that i cant check to have it installed or anything like that. its then "Gij" and its description is it is "the gnu java bytecode interpreter" i just dont know if i should just go back to an earlier form of ubuntu because these problems didnt start happening until i upgraded to the new ubuntu
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.
View 4 Replies View RelatedI have recently downloaded and installed Ubuntu 11.04 inside my copy of Windows. When I boot my laptop, I have the option to either boot in Windows or Ubuntu. When I boot in Ubuntu, I get the login screen all OK. But when the screen loads up, it is missing the top and left hand side navigation bars. It then appears to be trying to refresh itself (unsuccessfully) as after about 30 seconds the screen goes black and then the wallpaper image will come back, still without the navigation bars. This keeps on happening until I reboot the machine. The only way I can get the screen to reboot OK is to run the repair option on boot up.
I have notices that after the above has taken place and I have finally got the system to boot all OK by running the repair option, the system will not connect to my mobile broadband via the USB dongle. Not sure if they are related, but at this point they seem to be.

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?
I am having some issues with my screen resolution. I am not sure if it is a monitor or graphics card issue. I believe I have the ATI x300 card. I am gunning a dell dimension E510. My monitor is a MAG Innovision. The screen resolution keeps changing. I had this same issue with 11.3. Also, the screen looks fuzzy in certain places, especially white areas and bars at the tops and bottoms of pages. By fuzzy, I mean it will be a color that doesn't belong there and it will kind of look like static, in either a line, or a blob, or just the whole box. I recently had to disable all desktop effects because they would make the screen unusable.
View 1 Replies View RelatedI 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.
