Ubuntu :: Boot Screen Black With Lots Of Pixelated Garbage?
Aug 16, 2010
I tried to install a a custom splash screen using this guide [URL] and got as far changing the settings with Startup Manager. I found out that I didn't have an 'Appearance' tab so I reverted all the changes I've done in the 'Boot Options' tab. I then closed Startup Manager and rebooted back into linux. Now instead of seeing the purple Unbuntu screen, I see a black screen with a lot of pixelated garbage. Why I don't have the necessary tabs in Startup Manager to install a theme? I'm using a Macbook Pro 5,5.

I turned on my Acer laptop and during bootup it seemed normal. After it passed the blue Acer logo, all I could see is a black screen and a black cursor outlined in white in the shape of an X. Thinking it would be a one time thing, I turned it off again.it still was a black screen.

I am currently in the process of moving around 20TB of data from one server to another. Security is not a concern, since the data are freely available to anyone on our network anyway. There are a couple of things that I'm trying to decide on:
(1) protocol choice
Of all the choices I have--nfs, ftp, scp, rsync, samba--has anyone done any benchmarking to show which would be the fastest/most robust transfer protocol? I know nfs has slow write speeds for synchronous transfers. Asynchronous would be faster, but less robust. I'm leaning toward rsync since it performs md5sums to confirm the file transfers. (Remember if there's a 1 in a billion chance that a byte will get corrupted, then I'll have 20,000 corrupt bytes in the transfer.)
(2) Nautilus emblems
We use emblems in Nautilus to categorize files. The old and the new server have the same directory structure.Is there any way to copy the Nautilus emblems from the old server to the new server. What I want is that if a user had marked a particular file with a star on the old server, then that file would be marked with a star on the new server when he/she logs in.

With 10.04 final i still have the issue with a very distorted screen. Works with RadeonHD driver but performance is utterly crap so no good solution. Also when adding new panels they become invisible and only a logout and login makes them visible around the border. Errors somehow related? How do i file a bug report?

I've got two laptops running Ubuntu. Both have had Lucid installed from the live cd. I have upgraded one of them to Maverick. Both distributions are running great after they boot up, but I haven't experienced any faster boot times with either distibution. Both boot to Bios and then the screen goes black with a blinking cursor in upper left corner of the screen. The black screen remains for 30 to 45 seconds and then I get the Ubuntu splash screen for maybe 5 seconds, and then desktop. Why am I not seeing faster boot times? I realize 45 to 60 seconds is good compared to other os's, but I anticipated much faster boot times. Shut down on the other hand is quite fast at maybe 5 to 10 seconds. Does anyone else get this black screen on boot? Seems like wasted time cause I can't tell what's going on during the time there is a black screen. This is not a real big deal breaker, as I don't reboot very often, but I just wonder why bootup isn't faster.

I actually have two reasons for posting this. One is to see if there's an actual name for characters like this:Hopefully that will show up correctly for you. If not, it's a little box with four numbers in it, one in each corner. I don't know their name or their reason for showing up, so it's hard to look for help.
My main problem, though, is that I wrote a program that prints some output to a console using ncurses as it runs. These characters show up on the console, seemingly at random, and disturb the whole thing. Sometimes I'll also get sets of characters like "[13;" I'm not printing anything bizarre on there, just strings and floating-point numbers.

So, the problem is that _sometimes_ (I'd say around 5-10% of the time) when booting ubuntu, right after the splash screen (that pulsing white ubuntu logo on a black background), when normally GDM should pop in, I get a black screen and it stays like that and I have to reboot the machine. This is very annoying because I get this behaviour sometimes 3-4 times in a row... Also, sometimes (maybe half of the times when I get that black screen) the HDD LED on my laptop remains lit and the caps lock LED flashes. Right now I'm using a clean install of ubuntu 9.10, but I had the exact same problem with a 9.04 install and a 9.04 to 9.10 upgrade (so I had 9.04, I had the problem, I then upgraded to 9.10, the problem remained, and then I did a fresh install of 9.10 and the problem is still there).
My hardware is a Asus X51RL laptop, with a dual core CPU, 2GB Ram and a ATI X1100 video board. I also could paste a copy of any log you want me to, to help you identify the problem (but it would probably take some time for me to get that black screen, and also I hope that the logs remain saved after I do a hard reboot).

I'm going through this again. I posted this here as well as in the Mint forums because the architecture is very similar. What happens is that when I reboot, the screen goes black at the steps of the boot after about three seconds with each step. So I see the bios enumeration, then the screen goes black; I see the start up sequence with "Linux Mint" and the green/white dots beneath it, then the screen goes black; then finally, I hear (but don't see) the beep when the password login prompt shows. But if I get into the bios (dealing with the screen going black each time) and change it to "load default settings", then it reboots and works fine. Till the next time I boot.

I was messing around with the screen orientation and thought it would be funny to orient it sideways. Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.

Last weekend, I upgraded my old PC and installed Ubuntu 9.10 on a brand new pc. It worked perfectly for 5 days. When I got home tonight, it wouldn't boot and got stuck on a black screen.
[Code]...
I really am a newby here but I think that the blkid command gives me my uuid. The uuid in the /dev/disk/by-uuid directory is in blue so I'm guessing that this is a symbolic link. And then, when I try to create a symbolic link with the ln command, it already exists... But the issue is that the UUID that is referenced in the error displayed is not the same as the UUID in my /dev/disk/by-uuid directory.

I have had a really bad day (the first, after months of faultless operation)) with my Acer 5720Z laptop running Ubuntu 9.04 Jaunty. First thing was at the second startup today, nothing other than totally black or white screens showed during boot. However, the ubuntu jingle was heard after the normal time it takes to boot, so I was certain it was strictly some video problem.
Ok, so after having thought about this for a while and reading about similar issues here and there on the web I was struck by the fact that not even the Acer screen with bios info etc. showed normally just after power-up. By then I had dragged a second, stationary computer to the livingroom, so I thought I'd check if there'd be video output from the Acer's VGA port. There was, and the ubuntu desktop looking perfectly normal. Aha! - only the backlight working on the Acer's LCD screen, but no video? So I thought I'd check for loose connectors to the LCD or damaged wiring (installed replacement LCD myself some months ago with no problems). This is going to be easy, I thought (being more of a gearhead/hardware type of guy) Turned the Acer laptop off and unscrewed the screen frame stuff. Now I just start it and switch back to internal display... For some reason (too many unclean shutdown(s) during the early "blind" nervous phase of the problem, I suppose) the Acer now hangs with a black screen before boot is complete and I am unable to switch between external/internal monitors. Fortunately I can use the external monitor (video is stuck to the external VGA on startup), get to command prompt etc. so there should be hope. But I have no idea how to sort this out after many unsuccessful attempts. (Recovery mode, disk check etc.)
I can't find any sort of safe graphics mode option in the GRUB menu. Booting from the Ubuntu 9.04 ("live" option) also finally stalls with a black screen and nothing further happening, just like the install that's on the PC.
how Ubuntu 9.10 runs on a stationary HP Pavillion 1840 which I rescued from the trash just like the Acer laptop.

I have an asus netbook with an intel GMA integrated chip. until now i had been using the out of the box drivers, hadn't changed anything, and it worked ok. I tried installing a graphics driver and rebooted. This time i got the command line only, logged in, uninstalled the driver (apt-get remove) and rebooted, now after i choose ubuntu in GRUB an instant after the ubuntu loading screen comes on it goes to black. I'm trying to find a way from within GRUB to get it to do a command-line boot so i could force it to use the default drivers (how would i do this exactly?), but when i press "e" and then put "text" at the end of the "kernel" line it doesn't change anything. so what do i do from here? worst case scenario i reinstall ubuntu.

Ubuntu won't boot, just goes to a black screen. When I use a boot disk, it gives me this error message
(initramfs) /dev/loop0 (cdrom/caspev/filesyste/squashfs)
(this may not be completely correct) What should I do?

so I had a black screen when I was starting up my PC instead of the normal Ubuntu with the dots underneath. I have Ubuntu 11.04 on a dual-boot with Windows Vista. It would still boot normally and work fine but I wanted it with the Ubuntu and dots etc.
After looking at many sites to try and fix it that didn't work I found this: [URL]. That didn't work so I found this next: [URL]
I did what it said by removing
Code:
vt.handoff=7
Then when rebooted I got the Ubuntu with the purple background and dots but the boot would hang (always when all 5 dots were orange). I booted into recovery mode and I chose "File System Check" on reboot and it would get to the bit with 5 orange dots then it would check disk for errors and go to login screen then work fine.
If I added vt.handoff=7 it would boot normally with a black screen again.
RESULTS.txt is from when I had vt.handoff=7 removed and I was in Recovery mode>resume normal boot>"sudo bash ~/Desktop/boot_info_script.sh".
RESULTS1.txt is from when I booted up with the disk check and was in Terminal.
EDIT: Also just recently I'm getting a lot of boot hangs, freezes (where everything on screen will freeze and if I was playing music in Banshee it repeats the last 3 seconds until I hold down button on PC), and it will sometimes just restart randomly. Not sure if that related or not...

I downloaded a bunch of updates with PackageKit, afterwards I had to restart. Now when I did, all I would get is a blank screen, no blinking prompt line or anything. I did a cold boot and the same thing happened. So, I tried it a third time and all is fine. I'm running FC11 and I'm glad everything is back to normal,but what might have caused this in the first place?

I have an alienware m17 with an Ati graphics card. I was able to log on and install all current updates as well as the card driver update where I was then prompted to restart. Upon doing so, I get the grub loading plus splash screen. My screen then goes blank followed by a noise in my laptop. I have tried nomodeset as well as taking out splash nothing has worked. Also, upon booting up I get lucky if I can get into Recovery mode.

Ubuntu has been crashing on boot. I used a recovery mode kernal and went into failsafe mode, upon which point a msgbox told me to switch to low graphics. Then Ubuntu looked completely normal and functional with no problems. To me - an Ubuntu amateur, it seems like a driver problem and that running in failsafe mode will have its setbacks.

I am relatively new to Ubuntu ; I started 6 months ago with 9.10 and it worked fine. Recently I bought from Ubuntu the 10.04 version in French. The installation (dual boot with W7) went well, I personalized the software and had the "brilliant" idea to execute the recommended updates. Restarting the computer I just saw for a couple of seconds the blip up left and then a black screen. Nothing else happened. Posts to the French Ubuntu forum yielded no solution, so I decided to reinstall 10.04 again. It worked well a couple of times, and then again I had the black screen and no boot. How can I delete the installed versions?
