Ubuntu Installation :: Purple Horizontal Lines On Screen After Kernel Update
Jul 24, 2010
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 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 have been using ubuntu wel a long time now and I know my way around in linux but I recently updated my laptop from ubuntu 10.04 to ubuntu 10.10 all went fine until I had to restart my laptop. I got a purple screen (loading screen) with 4 dots and a oldskool like font which said: Ubuntu 10.10 Right after that the screen goes purple and its like the system halts I hear no login sound etc just a purple screen. So I did a clean install from the 10.10 live cd which booted perfectly fine and the system was also useable like before. But when I installed the system and rebooted it again no problems.
But when I tried to install the proprietary nvidia driver (the recommended one) I got the same problem again the purple screen. After searching a while on the internet I only found posts which had the problem with ATI cards but my laptop is fitted with a Nvidia Geforce 9300 M card. So I tried several things like removing the xorg.conf (read it somewhere) which ofcourse did not work, and booting in graphics fail safe mode which worked. So the point is in 10.04 and 9.10 I CAN use my video card drivers but not in 10.10 is there a solution to this problem? I am talking about the 32 bit version of ubuntu and here's my system hardware profile:
Intel core 2 duo t7350 @ 2,0 ghz / 3mb l2 cache
2 GB DDR3 ram
160 gb hdd
Nvidia 9300m gs
Chipset: I dont know sorry
Model: Samsung R710

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 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'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 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've installed almost every version of ubuntu so far and four different versions on this computer, and I've never had a problem with the installation cd. The install cd on this new version however gives me only a purple screen of death with a white line down the middle. What is going on? The ubuntu-10.04-desktop-i386.iso file's md5sum is fine. I've burned it successfully on two different discs and still I can't install it. I've got a Dell 6400 with an nvidia geForce 7300 video card.

My problem is with the new Ubuntu 10.04 Installer, and the Plymouth Bootloader.
I have installed Ubuntu plenty of times before on my hardware setup, so 10.04 shouldn't be significantly different, however I can't seem to get it to go past the purple screen with the red dots.
If i let it sit there for a while, then press an arrow key, it takes me to the text which is as follows:
Code:
(process:404) : GLib-WARNING **: getpwuid_r(): failed due to unknown user(0)
unable to open '/dev/mapper/nvidia_afgjfcea'
unable to open '/dev/sda'
unable to open '/dev/sdb'

Yesterday I booted into the Ubuntu 10.10 CD, and hit the Try Ubuntu button. Ubuntu booted fine from the CD, and after trying it for a few minutes, I decided to install it.
I already had (and still have) Windows 7 installed, so, using the Ubuntu Installer, I shrinked the C (system) partition of Windows by roughly 14 GBs. 10 of which used for Ubuntu itself, and the other 4 as Swap Area.
Installation went fine, and I was asked to reboot - and so I did. However, upon restarting, I was 'welcomed' by a stuck, purple splash screen. So I used Recovery Mode, and updated my Ubuntu. That didn't change anything. I rebooted, started Ubuntu without the "splash quiet" commands, and instead used the "nomodeset" command. I logged in my Ubuntu user, and ran the StartX command. It didn't work, and I was given a few errors, including "no screen found", "Fatal server error", and something along the lines of "no NVIDIA module found (...,0)".
So what's wrong with the NVIDIA driver, really?

I upgraded from 10.10 to 11.04 and now I have a blank purple screen. I have searched and went through some of the steps members have been giving, but haven't been able to fix the problem. I can get into the computer going through the grub menu, but when I restart I go through the same problem.

If you had or have a black screen or purple screen problem in Natty, add support by subscribing to this Launch Pad Bug: Xorg's HAL causes Purple Screen or Black Screen on GDM startup. [URL]
Through helping people with these problems in the Ubuntu Support Forum (Installations and Upgrades) and through this sticky: [URL] this bug (above) seems to be where this problem is originating. It affects this problem with all video hardware types. As I said in this bug report: "Normal users should not have to be highly skilled "techies" to manually bypass a broken part of a system to make a released distribution work during an install or distribution upgrade"

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.

(ranting stopped, for now) I have ATI Mobility Radeon HD 4330 GPU in my Dell Zino system and finished the upgrade from 9.10 to 10.04 LTS and got the purple screen of death. tried the intel recommended fixes but got nothing. I cant even get into recovery mode.

Ubuntu and right now I am running it inside Windows. I burnt it onto a cd so I could install it onto my 2nd harddrive. I know the cd is fine. When I boot off the cd a purple screen loads up with some weird symbols at the bottom looks like a picture of a battery = and then a picture of a stick figure man. If I hit f6 I can get to the option screen. I've tried using noapci, nomodeset, disabling the framebuffer, and vga=normal. None of them work as soon as I hit enter to start installing Ubuntu it just sits there on the menu screen and never does anything.

I am having problems installing Ubuntu netbook 10.10 from a USB drive.
I have a Lenovo ideapad S10-3 with Win 7 Starter.
I have tried two different USB drives, one is unidentifiable, the other is a Kingston.
I have used Pendrive and Unetbootin on both.
I have tried formatting the drives to FAT32 from both the Pendrive option and from Win7's default formatting software.
I downloaded the iso from the Ubuntu website torrent, and I did an md5 check to make sure that the file matched up.
When I boot from USB, the purple screen comes up briefly, and after two seconds changes to a black, terminal screen on which a bunch of text scrolls and then it eventually freezes. When I click a button, the menus pop up, and when I click on either "install" or "run from usb drive," the same terminal thing happens. Someone recommended that I try installing from that screen after changing the f6 options to nomodeset, noapci (I think), and acpi=off. (I cannot remember the exact lettering, but they were options on that f6 menu.) None of these changed the result.
With the Kingston, the line that it freezes on in the terminal is:
[6.548159] USB Mass Storage support registered.
With both drives, when I use the Unetbootin install, the menu comes up, and when I click on either the 'run' or 'boot' options, the cursor in the bottom left of the screen keeps flashing but no progress. (No terminal-like screen with this one.) It is different with the other drive. How to proceed from here?

I initially had problems with the install CD giving the purple screen of death (a screen of vertical purple lines), however I managed to press F6 and set nomodeset and then add "xforcevesa no splash --" to the boot parametres (I guess) and I was able to boot into the live CD. Now however, I've installed 10.4 and I'm back to the purple vertical lines. My Dell 6400 laptop has an nvidia 7300 video card which must be the problem. My question is, how do boot into some kind of low graphics mode so that I can install the proper video drivers? I've been pressing shift to get to the grub menu, but the recovery mode only gets me the purple vertical lines as well, and I don't know what I'm doing.

I have a problem, so I boot in recovery mode. The Recovery Mode menu comes up, but when I press a cursor key, the purple Ubuntu screen comes up. I cannot get to the menu items that I need!
The recovery mode is supposed to provide a failsafe text-only environment.
Does anyone know what app puts up the purple screen?
I would really like to remove it. I tried to install xdm, which I prefer, but keep running into the purple screen. - With XDM installed, the purple screen comes up and blocks you from seeing anything. Fortunately, remote login by RDP still works. - If you switch console (CTRL+ALT+Fn) back and forth a few times, the purple screen appears again. You have to go to a new console (F8 or even F9 instead of F7) and begin a new Gnome session. Eventually you run out of function keys...
Perhaps I'm using the wrong distribution. Ubuntu is friendly, but you pretty much have to use it exactly as it installs. Can someone recommend a distribution that puts more emphasis on stability?

I just upgraded from Ubuntu 10.10 to Ubuntu 11.04 Natty Narwhal and now I've got a purple screen of death. The download and install process all went okay, but when I restarted the computer through the upgrade dialogue to complete the installation process the system never came back online. When I turn on my computer it goes through the standard boot screen (F2 and F12 options shown while it boots the HDD, ODD, and wireless modem), and then it goes to a purple Ubuntu screen and doesn't do anything at all. I let it sit like that for 30 minutes before turning off the power and trying to boot again, but the same thing happened. I can press CTRL-ALT-DEL and the system will reboot, but nothing I know to do will get me past the purple screen and the Ubuntu logo. DI'm using a Dell Studio 1 desktop computer. It's got a 2.5ghz Pentium processer, 4gb of RAM, and a 400gb HDD. I don't dual boot, and Ubuntu is the only OS installed.
