Ubuntu Installation :: What Is Making Long Black Screen Or How To Reduce Time
Jun 11, 2010
I keep hearing about how Ubuntu is supposed to be so much faster than Windows 7, but have yet to see any major difference in their boot times. I am dual-booting Windows 7 and Ubuntu 10.04 on an intel Centrino 2 processor with 4Gb of ram and both OS's take about the same time to boot. After I get to the bootmanager to select OS, if I click on Windows 7 it almost immediately goes to the GUI load screen with the windows logo. On the other hand, if I boot into Ubuntu I get a black screen for ~30 seconds before the Ubuntu logo even appears. Comparing GUI boot times, Ubuntu is clearly the winner, but they take the same time total.
Does anyone know what is making the long black screen or how to reduce the time? I would really like to show people how fast Ubuntu really boots.Immediatly before Ubuntu Gui starts, an message shows up for a second saying something like "Unknown adaptor version (2): You may experience some problems", it flies past so quickly that may not be verbatim.

I have recently installed 11.04 natty on Intel Core i3-2100 3.1 GHZ using its own graphic accelerator. When the screen is idle for a long time, more than 1 hour, I get a black screen with the mouse arrow but nothing else. the mouse moves the cursor and Ctl+Alt+F1 does work. How to fix this problem?

I've installed Ubuntu on another PC and most things are great except fore the black screen that you get when you start the PC (just before the Ubuntu Logo). It stays black for 20 seconds. Is there something I can do to make it shorter like on my other PC.

Has anyone got Ubuntu 10.04 working on their Dell Inspiron 1100? Most of the time, the screen goes black a short time after boot. Sometimes it goes black right after the splash screen, sometimes I get to log in and then it goes black a little later. Same results when trying to boot into "safe graphics" mode. Ubuntu 7.10 works fine on this machine (although I had to do some special configuration in xorg.conf to get it to work way back when I installed it.) However, it does not appear to be possible to manually configure X in 10.04. I tried disabling the splash screen in grub based on suggestions I found for other Ubuntu versions, but that had no effect on the problem.
Is it possible to replace X with the most recent version that could still be manually configured? Would anyone know how to go about doing that?
Alternatively, if it's impossible to get this old machine to run new versions of Ubuntu, has anyone had success with (relatively) new versions of other distros on it?

I am running Centos 5.3. I ran no updates, performed no installs, nor changed any configuration immediately prior to this issue. My problem is this: when I run the command startx (default runlevel 3), it is a long time (5-10 minutes) before Gnome startx, and once it does start applications will not run. Also, when I try to use sudo (from any environment, even ssh), it is a long time (5-10) before the command is executed.
I cannot say for sure, but it seems like this is an intermittent problem. Sometimes X takes a long time to start, but once it starts it will launch programs. Sometimes X takes a long time to launch, but once it starts it will only launch certain programs. Though presently X always takes a long time to start, and I cannot successfully launch any programs.
A while back a had a similar problem to this (x taking long time to start, sudo taking long time to execute) and it ended up being a DNS problem. Unfortunately, I cannot remember exactly what it was and I stupidly did not document it. Maybe this is also DNS related, I don't know.
I don't know what log files to look at for problems with X, Gnome, and sudo taking a long time to start.

After installation of Fedora 11, I click reboot, it ejects out the disk, but is stuck at the screen for a long time and doesn't reboot so I manually had to reboot it. Today, surfing on firefox, it got frozen, and the touchpad worked, but everything was frozen nothing moved so I had to manually shut the laptop down. On bootup everything was ok. Im worried about corrupted files.Should I just reinstall Fedora 11? m using a dell studio 1555 laptop

I've been a happy Arch Linux user for years now. Recently, on my eee 1000he (an Atom netbook with intel GMA graphics) I've been seeing strange things. After it has been on for some time (usually hours), the screen starts to jitter, just for a fraction of a second, every now and then. After this has happened some times, the screen goes black (one time it went red). The backlight is still on and I can still ssh to the machine which reacts normal appart from the black screen. I can only regain the screen when rebooting. What could this mean? Is it hardware or software? X logs don't shown anything weird, where should I look? I haven't found anyone with the same problem on the net.

Ubuntu 9.10, x64. Around 30-40%of the time, after i login, I just get a totally black screen. If i leave it for a few minutes, nothing seems to happen. Whether or not i get login seems fairly random, and I don't notice if there is any common factor- This is always from a clean boot, and i could be on power, or not on power.This is on a HP 6730b, so the video should be a Intel GMA 4500.

I just installed the newest version of ubuntu on my Alienware desktop. It installed fine and I was running everything perfectly. Then I restarted the computer, just to test that out, and now it won't let me get back in.
It takes me to a screen which asks me to select the OS. I select "Ubuntu with Linux 2.6.35-23-generic-pae", but then it goes to a black screen with the blinking cursor, and nothing happens (even after waiting >10 minutes)
I'm booting off of the internal hard drive, since that is where I installed Ubuntu initially.

I have just made a clean install of Ubuntu 9.10 and after installing all updates, GDM is taking a long time (about one minute) to come up after a clean boot, resulting in a regular console prompt.
If I issue "sudo service gdm start" it does come up promptly.
What can I do? Where can I see startup logs to try and identify any problems?

I'm having a problem with a server I just got. The first thing I did when I got it was to format the drive and install ubuntu server, but on booting up I got a black screen and my monitor (samsung syncmaster914v) displayed a bouncing notification with the text "not optimum mode recommended mode: 1280 x 1024 60hz". However at one by using a combination of plugging in the monitor after booting, and pressing random keys on the keyboard I was albe to boot into the server, and was able to access the monitor meu, which told me it was running at 640x480, and 60 hertz. having access to the console I stupidly tried changing the resolution and then rebooted, getting the same black screen.

I'm attempting to install Kubuntu on a new laptop but seem to be having some strange issues. It's a Dell Latitude E5410 with 160GB HDD, 2GB RAM and Intel Core i5-520M(2.4GHz). I'm trying to install Kubuntu 10.10. When I restart the machine and boot from the CD for an initial install it seems to hang for a VERY long time. It will eventually get to the boot options (after hours) but seems sluggish. Once the install gets going everything seems decent except for that I can't seem to get it to finish. I know the CD is good since I used it to get Kubuntu on 2 desktops and another laptop in the last 48 hours. I've also burned another CD just to make sure. The checksum was spot on. Does anyone know what I can do to get this remedied?

I'm trying to fix a friends EeePC notebook (Asus) running a recently upgraded Ubuntu 10.04 from Karmic Koala. She used the update manager for the upgrade to 10.04 LTS and everything was fine until she had tried to install something from the Ubuntu Software Center (she doesn't remember what happened). After that, both Update manager and Synaptic stopped working.Update manager gives the following error:Quote:Software index is broken. ... Try to use synaptic for something?!...
Then Synaptic manager gives the following error:Quote:E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. E: _cache->open() failed, please report.And when I try that command, the terminal just keeps blinking with the cursor and does nothing for more than an hour. This is the output of the comand:Quote:
jasna@Jasna:~$ sudo dpkg --configure -a
[sudo] password for jasna:
Setting up moodle (1.9.4.dfsg-0ubuntu4) ...

I recently broke down in the face of morbid curiosity and clicked that little version update button. it seems to run flawlessly (after i uninstalled the pesky touchpad) but it takes a long time to boot up now. at least a full minute. is this normal?
I will add also that it said my version of grub had been modified (which i dont remember doing, but may have) so i told it to leave the current one in place.

I'm using OpenSUSE 11.2 64 bit. Sometimes boot fails and I get a black screen. It starts quite normal, but when it tries to start X and KDE, it fails and I only see a black screen. I can't switch to terminal and I can not reboot my computer by pressing "Ctrl + Alt + Del". It doesn't even shutdown by pressing the power-button. The only possibility is to switch off the computer. Then it normally starts.
The problem also occures with a clean installation of OpenSuse. And it cannot be solved by updating kernel, X-Server and KDE.
What files do you need? I'll post them.
The same computer worked fine with OpenSUSE 11.1. I think, the new radeon driver could be the problem, I have to use it because I can not use fglrx anymore as with 11.1
I take a look into my log-files, but I cannot see any error. Sometimes it seems, that /var/log/messages is partly overwritten by restarting the machine.

It takes me a while to log in the splash screen just sits there for ages before i get to the desktop. Never used to be this slow and I'm not sure why. Firstly, I'm running Ubuntu 11.04, standard DE. I do have conky starting up in a script but it has the & at the end of the line so I didn't think this would cause it (or is there some special case for log in time on how & is treated?). However as a test I will comment out the line in the script and see if it is the cause.
However just for general knowledge and in case that isn't the problem, how does one go seeing what is happening during the time from when one log's in and the desktop is displayed? Is there some kind of log that shows the date/time that can be enabled or is there a debug mode that can be enabled somehow via special keys or maybe from grub?

just upgraded from 9.10 to 10.04LTS and upon first reboot it gets stuck at the splash screen.. it just keeps loading over and over, nothing happens.I don't have the liveCD as I just did the download from the internet via Synaptic Softwarethis is what I tried:hit ESC when GRUB menu loads.. tried to hit "e" on the boot option and nothing happens.. I was told changing quite splash to nomodeset would fix it but it doesn't even say quiet splash, unless someone wants to walk me through it.I'm soo frustrated, I have tons of e-mails and documents that I need to save.is there a fix to get me back in just so I can copy my emails and docs and do a fresh install?

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 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.

another post about this. I just don't know how to handle this, as I'm pretty nsee the grub loading menu, but screen just freezes after, no way I can reboot, or open a console. In recovery mode I can log as root in console, though.I run Debian 6, 64 bits. I have an intel q6600 and a nvidia geforce 9800GX2.

I have an Acer Aspire netbook with 1GB RAM and 1.6 GHz dual-core 32-bit x86 chips. The KPackageKit / yum / rpm chain is running too slow for me. In addition to the time required to download any new packages or updates, it seems to require at least one full minute of processing time to install each package, update, or bug fix, no matter how small. Another full minute is consumed for each package in "cleaning up."Running yum from the command line takes nearly the same amount of time.During this time, I cannot run any other applications without severe thrashing. It seems that a full gigabyte of memory is in use with some 100M swapped out to disk.
Is there any way to reduce the running time and memory requirement of the update process?While not updating or installing software, I do not normally run out of memory (i.e. begin thrashing) until I have about a dozen browser tabs open, or the like.
