Ubuntu :: System Freezes At Purple Screen On Boot
Jul 17, 2011
Every once in a while when I turn on my computer it freezes on the purple screen after the screen where you choose the operating system. When this happens the keyboard doesn't work and I have to hold the power button. Also I think this might be connected to the problem I had when I was running ubuntu from the live cd, which was freezing after choosing the option of "trying" the OS before installing. I'm using an HP Dv7-3112sa and am running the default 64bit ubuntu from the website.

When I try booting my computer under Ubuntu, it freezes whenever it gets to the part of the purple loading screen (with the Ubuntu logo and the red/white dots indicator). I won't load any further, but I can still turn it off by pressing the power button. Has someone else got this problem? Ubuntu was my main partition, and I don't have any practical way to make a hard install.

I downloaded the latest LTS last evening , placed it along side my Win 7 , things went well seemingly until I got the install done and restarted the pc. From the initial purple log in area, the second I curse to the place to put my pw the screen blinks off to the purple screen, devoid of the login section and freezes, taking my mouse control away and then it just sticks. I have restarted quite a few times with the same issue. Is there a known issue about Win7 and the latest LTS concerning the log in screen?
if so, what would I need to do to correct, do I need to jump backwards to an earlier version and wait for the issues to be corrected? Is that even possible?

when I install them all goes well but when I get into the GUIs I can hardly press anything - major bug with mouse and it is really annoying. Secondly there is a big gap between the GUI and my screen's edge. Hmm, I think - it must be a problem with the GPU driver and that might be the thing also messing with the mouse clicks. I download the drivers provided by the Ubuntu community - all goes well and I restart - stuck at purple screen after the "moving dots" on boot. So I reinstall the whole OS and try with the drivers provided by NVIDIA - same thing. I try the same procedure with Kubuntu and no progress.

I noticed that after making my build in suse studio my system freezes immediately after GRUB ( Normal or Failsafe) boot splash screen. I also noticed that this happens only with the specified kernel below. I'm not sure when using Kernel 2.6.37, one had the same problem. I never used it. The original kernel 2.6.34 had no problems such as the one I have described. My systems has no further problems only that it takes several restarts to go past the "Freeze". Below is a list of my system specs:
openSUSE 11.3
Kernel-pae 2.6.38.2-4.1 from Kernel Stable.
GRUB 0.97-174.1 from openSUSE 11.4
Upstart 0.6.5-33.1
xorg-x11-server 7.6_1.9.3-142.1 from X11:xorg 11.3 repo.
The GRUB from openSUSE 11.4 has been very stable and non-problematic. I will be buying an Intel core i5-2500K in a few months that's why I need the latest kernel and XOrg-X11-server. What could be causing the freezing?

I switched back to my ubuntu installation few hours ago and I couldn't notice the strange boot screen! I remember that it used to be orange, there was the ubuntu logo and a nice loading bar. All is displayed now is a horrible purple background with just the text "Ubuntu" in the middle and a few dots just below it, showing the loading process.. I don't know how to restore the classic splash screen (I also found the original background in /usr/share/images/xsplash ).

I already had Plymouth issues on 10.10, which was solved by this script [URL]
After upgrade, boot only gave me a blank, purple screen, so I used his revert script then tried this : [URL]
But I'm only getting a black screen. Removing vga=795 option only make it stay purple. It might be because of the multiples workarounds I tried back in 10.10, but I don't know how to clean that up. I have an ATI HD Radeon Pro 2400 card with free drivers (but I was using the proprietary ones during upgrade).

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?

Iv'e tried on both CD & USB. Upon Live Boot from the CD I get the first purple screen, then "No Input Signal" on my monitor. Upon Live Boot from USB I've choosen both the Install & Boot options, then It thinks for a minute; and I recieve "No Input Signal". I'm leaning toward it being my "Graphics Card"(NOTHING IS WRONG WITH IT OR ANY OF MY HARDWARE!!!!; but it is an "ATI" ^_^), but thats just a guess. Iv'e Tried Both 32/64 Here Is My Hardware Information... (Everything is Brand New & Full Diagnostics)

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 installed Ubuntu 11.04 today as the main OS on my laptop.I had deleted my XP partition, and repartitioned it according to a guide I had found. (http:url)......Basically it was setup like this: 500mb ext2 primary partition, has the grub folder, I believe this is either the '/' partition, or the '/boot' partition 2gb swap space logical partition
10gb ext4 logical partition -- this is either the '/' or the '/boot', it contains the 'bin,boot,cdrom,dev' etc folders 243gb (the rest of my hard drive, with the exception of a partition that contains documents and files from my XP OS, formatted to NTFS) ext4, this is the one that has all my desktop/documents/etc folders.After Ubuntu was done installing, I had some message pop up about installing an ATI proprietary driver for my ATI graphics card (an ATI Radeon HD 4330, I believe, I may have messed that number up). I installed it and rebooted, no problem.
Next, I had another update window pop up with 198 items checked and ready to download and install. I went through all of this, and rebooted, again, no problem.Next thing I did was install some apps that were essential for me to have to use for my work (an ide, chat programs, etc). No problem with any of that.Last thing to install was the OSE Virtualbox, and then I installed WindowsXP Pro and Windows Vista Business, then installed the guest addition addon for VB. This all worked without any issues whatsoever.
Time goes on, and I notice my computer is heating up much more than (seemingly) normal. I begin to wonder if its my graphics card. So I shut down the computer and let it cool down. Reboot, and no problem, still working fine.Then I opened a couple of apps and tried a simple game (can't remember the name) I believe it was a simple 3d topdown, as I wanted to test my graphics card. This is where things seemed to start to go wrong. My laptop began hanging, not even allowing me to access the terminal via ctrl+alt+f2. The screen flashed and I saw the blue/green/grey fuzz that I get when the graphics card is starting to heat up too much. Then everything hangs and I can't do anything at all, including move the mouse. I did a hard reboot (I believe this is what you call pulling the plug/pressing the power button, correct me if I'm wrong). I then rebooted, saw a chkdisk, then it booted seemingly normal, but it hung right after the purple screen after the grub screen.
This is pretty much where I'm at right now. I strongly suspect the fault is with the ATI drivers, but have been completely unsuccessful in my attempts to fix it. I've googled just about everything I could think of, along with searching these forums. I've tried just about everything listed in the forums, but to no avail.I've tried the commands that are supposed to purge the ati drivers, but all I get are errors that say they can't remove the 'virtual drivers'.
Right now I'm booting off a live cd, so I know the computer still works fine, just not my actual installed OS. I'd really like to get the issue resolved without having to reinstall, as it took quite awhile just to get it usable in the first place, but this has already taken so much time, I may just resort to that if we can't solve it any other way. Got too much work to catch up on as it is.As a re-instated note, perhaps if you have any tips, but not particularly about fixing the OS, my laptop (I'm strongly guessing my graphics card) is heating up much more than normal, compared to that when XP was installed. Is this more than likely just a driver issue, as is the rest of it? Also, I did have Compiz installed, though I didn't choose for it to be installed, I believe it came pre-installed. I've heard it could cause some issues, though I have no idea as to the validity or relation to this particular issue.
Edit:
I just remembered while searching for a solution, I found a post somewhere that said something about the information not being sent to the monitor from the graphics card properly, thus no desktop. I'm guessing that'd still fall under the driver issues, but again, I'm unsure. I would think that wouldn't be entirely true anyway, since I can still see my mouse fine, just no desktop, only a black screen.

Don't know if this is a coincidence, but the other day we had a power cut and my laptop went off. When I tried to reboot it got to the ubuntu start up screen, but when it tries to get to the "desk top" screen it all goes blue and black flashes. I have XP and Vista on the same machine and these both start up ok

I'm using ubuntu 10.04 and it worked fine but recently I'm getting the following message -
(process:343) GLib_Warning** : getpwuid_r(): failed due to unknown user id(0).
This message comes with a black screen and then no key stroke works and everything totally freezes. then I've to force restart using power switch. This message appears when I'm using internet. I'm using pppoe broadband connection. Without internet it works fine. I'm getting the same prob in Linux Mint 9. I've googled for this problem and almost everywhere it is said that this message appears in booting time and after a few moments everything becomes quite ok but my problem doesn't match with them. I don't get this message in booting time. I get this message when I'm on internet.

i am fairly new to Ubuntu. i was using it fine for a month, but today, when i booted my computer up, it came up with a black screen instead of the normal purple ubuntu screen. the black screen had white text on it, and asked for my username and password. from there, it was a terminal prompt. i have been google searching for a while, and have tried typing "startx", "sudo apt-get install ubuntu-desktop", "sudo gdm", and i have also tryed uninstalling xorg, and reinstalling, and none of these things wanted to do anything for me.

The system freezes after the screen saver. 'Blank screen' is used. I can't do anything, so I reboots the machine from another terminal. I am using CentOS 5.4 x86_64.

The system frequently freezes the screen. The mouse is still moveable but there is no reaction on any click. Keyboard does not work either (pushing Num-Lock does not toggle the Num-Lock light on the keyboard). However, Alt-Print-b works for a reboot. The only other way out is to turn of the computer.I had this effect some time ago where I thought it was a problem due to the NVIDIA graphics driver. Since then, I changed back to the standard VESA driver and thought the problem would be gone. Just a thought
I toggled through the log files in /var/log which had the file date/time of the crash but I could not find any hint.Which log files could I look as well to dig for the problem? Or any idea for such an effect?

I recently upgraded from Hardy to 9.10 Kubuntu. The install went smoothly, and when I boot up, the loading screen (the one with the progress bar) does its thing. Then I see the 'waiting' cursor (in Kubuntu, the two dots chasing each other around in a circle). I see this for about two to three seconds, then the entire thing freezes up and I can't do anything, including switching to a virtual console. How do I figure out my system's dying words so I can figure out what's going wrong? As a (sort of) aside, when I open files in /var/log for reading with cat <file> | less, I have to Page-Down a whole bunch to get to the most recent stuff. Is there a way to jump to the bottom, or read with something other than what I have been using?

i start up the computer, it loads, it arrives to a screen that says the laptops name, and a bar at the bottum. I can interact with this bar, it is blank and has a picture of a little man with a circle. Clicking on this does nothing, another says shutdown and reset, again clicking on it does nothing. I think the error occured when the computer got unplugged while updating.now before we get into all this GRUB and fancy stuff. I am completely new to linux. I installed this using a cd made from an iso image downloaded from the site. I did not use a windows loader. I don't even have windows anymore. I have all my personal information and data on here and would like it to be restored.I googled it and it says to go to recovery mode using GRUB, don't know how and don't know what grub is.:confus ed:

After a hardware freeze, my system boots directly into the Ubuntu screen with 5 dots and hangs. Booting into recovery mode loads the tools menu then freezes before I select anything. The system still boots and runs windows 7 from the same hard disk just fine. I've booted a live cd and run file system check on my ext4 partition and it says it's clean. I can mount the volumes and read the data, just can't get the os to boot.Any suggestions before I backup and reformat?

I set up a dual boot on my laptop a few days ago, between Windows XP and Ubuntu 9.10 (installed from Live CD). All the hardware is working fine.
Anyway, SOMEtimes, during the splash screen , the screen turns off (physically turns off) and the hard disk seems to stop. I cant do anything appart from force it to power down.
Yet sometimes, it boots up fine.
I want Ubuntu to work first time EVERY time.

Im running desktop dual boot system with two hard drives, one with Windows XP and the other with Ubuntu. Ive had no problems with this until now when I upgraded from Hardy to Lucid. Now I have problems with the system freezing on boot up.
Sometimes it will boot just fine, and at other times it will freeze before the login screen appears. When it does freeze, there are flashing lights on the keyboard and the floppy disk light (yes, its an old computer) is lit constantly. The only thing I can do is switch the computer off and hope it will boot up properly the next time.
When I did the upgrade there were a couple of files where the program asked if I wanted to keep the custom file or overwrite it with the maintainers file and I chose to keep the custom one. I THINK one of them might have been GRUB, but Im not sure.
Has anyone had a similar experience and were you able to cure it? I have seen a thread where people have had the system freeze on them, but Im not sure its QUITE the same thing.
Ive also done a clean install with Lucid on my laptop and have had no problems. The laptop is only running Ubuntu.
Im also wondering if reinstalling Grub on my desktop would solve the problem.
a. If so, would it still show both operating systems?
b. How do you do it?

I'm a bit of a Linux novice but have taken the plunge and got a old Dell machine set up with Fedora 13, it works fine for the most part. If I can get it to boot. Whenever I start it up the tri-color boot bars go across the screen but seem to freeze at various times. Sometimes right as its getting started, other times it will go all the way across but never actually do anything. I can sometimes get it to work if I get into GRUB and try a different kernel version. Is there anyway to pull up a more informative boot screen or some other way of figuring out whats causing the freeze instead of just watching the progress bar?
