Fedora :: No Shell After Upgrade - Screen Flashes On Login

Sep 29, 2009

I upgraded from fedora 6 to fc10 using a net-inst iso. Everything went great however when I rebooted gnome wouldn't start up and there were other error messages, however thats not my current question. I figured id login as root, I put my pw in and the screen briefly flashes and then back to login prompt. The flash is a message saying something about no shell. Same occurs when trying to logon to my main user account. I can boot to single user and see that all my partitions are there and the data is there. My password file has the shell at the end of the entries.

Ubuntu Installation :: Screen 'flashes' After Upgrade To Narwhal?

May 2, 2011

I have a Dell Inspiron 5150 which I first upgraded 'over-the-air' to Narwhal. This completed with no errors. After reboot, the screen momentarily displays some icons before reverting to the background - this loops round every few seconds.I've subsequently tried installing with the CD which runs through with no errors, but does the same thing when it's finished - blink... blink... blink...

Ubuntu :: 9.04 Upgrade Fails On Boot - Screen Flashes To Black

May 2, 2009

I have just finished updating my older box from 8.10 to 9.04 and installing a bunch of programs. I had shut it down several times between sessions but when I unplugged it and moved it, it fails. It goes fine through the BIOS and GRUB (I think) but then when there is a screen of text it flashes to black several times and then displays a screen that looks like static with "Ubuntu" barely visible in several places.

Fedora Installation :: ZFedora 12 Upgrade Login Screen Blurred

Jan 11, 2010

I was using Fedora 11 for the past few months. It was working fine. I upgraded yesterday to Fedora 12 and now every time I boot up, the fedora logo screen comes up, the "f" is filled up and after that the screen goes hazy. I was expecting the login screen but nothing comes - the system freezes sort of.

I don't really have any Linux experience. But I wanted to try it out. Now I'm afraid I did not set this up properly. Grub gives me 3 options:

Fedora (2.6.38.8-32.fc15.x86_64)
Fedora (2.6.38.8-26.rc1.fc15.x86_64)
Other

When I select <Other> to boot into windows... it starts to try to boot... but then flashes a quick blue screen & restarts. I tried to boot into Window's normal mode, safe mode, and command line... all just restart fdisk -l gives the following:

Ubuntu :: Will Not Load GUI -- Screen Flashes At Splash Screen

May 21, 2010

Out of nowhere Ubuntu (intrepid, I believe) has stopped loading for me. When it attempts to load gdm the screen starts flashing at the splash screen and then eventually dumps me to the terminal. From there I can login without any problems but can not get the GUI to load.

When I run sudo gdm-binary it does the flashing splash screen again and then spits out the error message: WARNING: Unable to find users: no seat-id found. Then a few warnings about longest graphic displayed 2.5xxx seconds
I tried running sudo dpkg-recondifigure gdm and relaunch gdm as above and it did the same thing.

I was not able to successfully connect to my wireless network through the terminal to try to update in the hopes of that fixing the problem. Perhaps someone can give me instructions on how? (I have tried but can not figure out how to initialize wlan0).

Or, is there something I can do from my installation CD?

Software :: GNU Screen Doesn't Start Shells As A Login Shell?

Mar 22, 2010

I want to have an ls' output colorization in gnu screen. Colorization in my system (Slackware 13) is realized by aliasing of ls in /etc/profile.d/coreutils-dircolors.sh:

Code:
$ alias ls
alias ls='/bin/ls $LS_OPTIONS'
where $LS_OPTIONS is
Code:
$ echo $LS_OPTIONS
-F -T 0 --color=auto

But in screen this alias isn't defined. It seems like /etc/profile script isn't executed at shell starting in screen. I think it happens because screen starts a shell not as a login shell. I tried to correct it by adding to ~/.screenrc or to /etc/screenrc. The problem is the same. By the way when I start screen as a root I haven't this problem. What's wrong?

Ubuntu :: Screen Loads And Then Flashes Black?

Aug 29, 2010

When I load Ubuntu, it goes to the desktop screen, shows my desktop picture, loads Pidgin which I have set to start on startup, loads Icons, and then the screen goes black. The mouse cursor shows up, I can move it around, and then it goes black again, and the mouse cursor shows up again. This repeats a few times until the cursor freezes. This started happening after I tried fixing a bug with new drivers for my Intel 845gl video card. The instructions I followed are these:

Code:
To use the available fix, run the following commands:
pt-add-repository ppa:glasen/855gm-fix
apt-add-repository ppa:brian-rogers/graphics-fixes
apt-add-repository ppa:glasen/intel-driver
aptitude update
aptitude install linux 855gm-fix-dkms
aptitude dist-upgrade
,taken from here.

I have tried some of the options in recovery mode from GRUB menu, none really work, except booting with default graphic configuration, or something similar like this.

Ubuntu :: No GDM / Login Screen After Upgrade To 9.10?

Feb 25, 2010

I installed Xubuntu 9.04 on an old Acer Aspire 1200 (PIII, 256Mb of RAM). The install went ok and I was greeted with a login screen at the beginning of every new session.

I later upgraded to Xubuntu 9.10 and since then I've lost the login screen. All I'm left with in the shell (tty1) for which I have to put in my login and password before I can do anything. Typing startx at the prompt starts the desktop.

how I should reinstall GDM or its XFCE equivalent?

Ubuntu :: Locked Screen Flashes Between Vertical Bars And Terminal

May 14, 2010

Ubuntu 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".

Ubuntu Installation :: Cannot Get To Login Screen After Upgrade On Karmic

Jul 14, 2010

I did an upgrade on my system yesterday. After the completion of the upgrade on restarting the system the computer enters tty1 mode straight without giving me the GUI login screen making it difficult for me to work. The question does now is what could have caused this to happen ? Have i gottten something wrong somewhere?

To switch to tty7 mode i hit the key crtl+alt+7 but it gives an error message about an unknown user even after login in with my username and password on tty1. Start the computer on recovery mode and selected the option correcting broken packages and it produced a result requiring me to download some new packages. I have a huawei e1550 modem which i use to browse in Nigeria. I want to know how i can connect to the internet on the tty1 after insertion of the modem so i can download the necessary packages it requested on issuing dpkg command

Ubuntu Installation :: Upgrade To 10.04 - Login Screen Crash?

Oct 30, 2010

Today I was prompted to upgrade to Ubuntu 9.1, and then again to 10.04

Doing these upgrades wreaked havoc on my system. I have been able to fix most of the problems that were caused but I am having trouble finding information on the following:

When I boot up the system and after passing the GRUB loader, the system freezes up at the login screen and I have to power down.

If I hit ESC at the GRUB screen and choose Kernel 2.6.32-25-generic (recovery mode) and then choose "failsafe graphic mode", then I am able to log in to GNOME as normal.

Ubuntu :: Login Screen Cycles/loops After Upgrade?

Jan 8, 2011

I was running 10.04 until yesterday, when it occured to me that I could upgrade to 10.10. So I went to Software Center, set it to get normal releases and left it to do its job. The upgrade appeared to go without a hitch and I rebooted. The login screen appeared. But just before I could click on my username and enter my password, the screen went blank and a second later the login screen was back. But then just before I could click... Undeterred, after half a minute of frantic clicking I did manage to click on my username and get the password prompt. This time, the login screen didn't go anywhere. Yay. To cut a long story short, this is now my standard logon procedure. However, the plot thickens. I appears that instead of 10.10, I ended up with 11.04, Natty Narwhal, which 'was released in April 2011'. If I download an .iso of Maverick and install it over my current version, will it leave my data unharmed AND reset everything so that it works again?

Debian Installation :: Squeeze - Machine Flashes Fonts And Screen Blips

Aug 15, 2011

I have been using Debian for three or so years now. Not sure what all the difference it makes, but I'm installing Debian Squeeze on a Sony Vaio desktop computer... With an nVidia GeForce 5200 which works perfectly in other computers and on the same computer when dual booting with Windows XP. I've tried and installed several times already to no avail. When I fresh install just the standard system, no graphic desktop, no Xorg, no servers, no nothing, just the standard system, command line only. When I do the initial boot on this blessed computer, part way through the boot process my monitor shuts off and it says frequency out of range (thats a message from the monitor itself, not the computer or debian).

The same install process I've executed countless times. I thought it was a dependency issue, problem with X perhaps. I can install lenny, but not squeeze. When booting in single user mode, it seems like it craps out either during or right after it loads or does something with the "drm" - you know how during the boot script, the machine "flashes" the fonts and the screen blips... its seems to me like that's where its happening at. The monitor works just fine, I really don't think that's the problem. But it is frustrating and I have no clue where to go about finding what the issue is if I can't see whats going on.

Ubuntu Multimedia :: Screen Flashes Black Before Video Play Back With VLC (ATi)?

Aug 2, 2010

I'm experiencing a sudden black flash before video play back with VLC. The whole 3 screens just flash black and come back, and then the video plays fine in VLC. This doesn't happen with other media players, such as mPlayer and Totem.

I'm running an XFX Radeon 5450 (ATi) with the propriety 10.7 drivers. Running 3 17" (1280x1024) in "EyeFinity". I've had a look on the unofficial bug thingy for ati drivers for linux, and there is a bug back from 2008.[URL]...

Just wondering if anyone has any ideas, of tips to start looking to try and solve my little issue, I've spent hours and hours looking though xorg, syslog and other logs in /var/log/ and nothing seems to stand out.

Ubuntu :: Won't Boot - Died - Startx The Screen Flashes And Brings Me Back To A Failed To Open Devices Report

Mar 30, 2011

After tweeking some graphics settings, and replacing some hardware, ubuntu won't boot. Being left in the X session (CTRL + ALT + f7), it's what looks like a log:

[Code]....

^ and that's where it hangs. So I went into ctrl alt f1, and logged in with my user/pass, and did the command: startx the screen flashes, and brings me back to a failed to open devices report.

[Code]....

I tried re-installing GDM, but turns out that the PC isn't actually online, hence unable to install GDM after uninstallation. So I downloaded the gdm .deb, and tried to install it from a USB flash drive, but I get dependency errors. I'm at a loss here, I could really use some help, this is the PC that has all my data on it, 450 GB +, I'd love to not have to transfer that over to a new installation!
