Ubuntu :: Cannot Login In Graphical Mode/ Won't Start X?

Mar 23, 2011

I'm having a problem booting Ubuntu. Last time I used Ubuntu I did 2 things that might have caused this:1- I added a repository to my software sources:

deb http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu (lucid main #xorg-edgers PPA)
deb src http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu (lucid main #xorg-edgers PPA)

Ubuntu :: Start Up Graphical Mode From Command Line?

Sep 19, 2010

Is it possible to instruct Ubuntu to start up (GUI) Graphical User Interface mode from (CLI) Command Line Interface mode? In the old days, you can type "win" in DOS to get into Windows - something along that line. Is it possible for Ubuntu in this case?

Yes, you can reboot to switch between the modes, but shouldn't there be a command for this?

OpenSUSE :: Root Can't Login In A Graphical Mode?

Jun 28, 2010

I was reading /usr/share/kde4/config/kdm/kdmrc and see this 3 lines:

# Allow root logins?
# Default is false

this doesn't mean that root can't login in a graphical mode? (I can login as root)

Ubuntu :: Start A Program On Remote Computer In Graphical Mode?

Feb 1, 2010

Sometimes I would like to start XBMC on my media center using my laptop. I manage this system fully via SSH, but there is one thing that I don't know how to do, or know if it is even possible. I would like to start XBMC from my laptop so that I don't have to reboot the machine in order to do that (XBMC launches upon boot). Is it even possible to launch a GUI on a remote computer using SSH, and if so, how?

Ubuntu Installation :: NVidia 8600GT - Start In (Tty1) Login Console Mode

Dec 17, 2010

I tried most methods suggested on many sites to install drivers
## through the additional driver panel only
## through the Nvidia.run file I downloaded
## through the terminal using apt-get

All failed to start ubuntu gui it takes me to the console login and I noticed it says "saned disabled" edit /etc/..something. This problem made me install ubuntu again three times and every time I activate the driver then install the driver Nvidia.run or through apt-get and both leads to a black screen tty1 login. So what to do now I installed and removed many things and I won't reinstall ubuntu again. Also I typed compiz and this came on:

root@ubuntu:/home/sherbieny# compiz
Xlib: extension "GLX" missing on display ":1.0".
compiz (core) - Fatal: Root visual is not a GL visual
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :1.0
Launching fallback window manager. I want to install properly so that I can start normally and enable the extra visual effects and the custom effects. Please elaborate the steps clearly

New Info:
When I enter nvidia-settings : server X opens and says
You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run 'nvidia-xconfig' as root), and restart the X server. When I enter nvidia-xconfig as root and restart nothing happens and when I enter:
nvidia-detector it says none
and when I enter: nvidia-smi

Error: API mismatch: the NVIDIA kernel module has version 260.19.21, but this NVIDIA driver component has version 260.19.29. Please make sure that the kernel module and all NVIDIA driver components have the same version.
Failed to allocate an RM client
Could not allocate resources!
root@ubuntu:/home/sherbieny# apt-get update kernel
E: The update command takes no arguments

A new and very exciting error everyone now also the windows 7 that I have besides linux has also crashed and cannot open the login window. I don't know whats happening all I know is that few hours ago I logged in to windows normally now I cannot login to either one of them and the funny part is: I'm working on my thesis on this computer and I cannot work anymore and I'm supposed to meet with the professor on monday.

Debian :: Automatically Start Graphical (SDL) Program As Root On Non-graphical Debian?

Mar 3, 2009

I'm not a Linux noob, but I am far from guru. I'm running a single board computer with a slightly customized Debian Etch (customized by the SBC vendor). No Gnome/KDE/X installed. My application is a control application which uses SDL (Simple DirectMedia Layer) to paint some basic graphics on the VGA. I need to run it as root because the application calls iopl() to access an IO port.If I run my application manually from the command line, life is sweet. From Googling around, I found http://www.debian-administration.org/articles/28, and hence I:1) Created a script in /etc/init.d2) Executed "update-rc.d scriptName defaults" to link the script into the boot sequenceAll very straightforward. My application starts at boot. But when I try to SSH/SFTP into the SBC, I get "Connection refused". So I can't manage the SBC anymore, and this is a big problem. I am not sure if it's relevant, but my application starts before the SSH daemon.My script looked like:

case "$1" in
echo "Starting my application"

Ubuntu Security :: Bad Login Protocols - Graphical Login For Gnome Sizes Itself To Accommodate A User's Exact Password Length

Dec 14, 2010

I'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.

And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.

I have a ATI Mobility Radeon X1400 card on ThinkPad T60. Everything was working on 8.10, and I decided to install 10.04 and now it doesnt work.

Debian Hardware :: Unable To Login To IMac G4 - Graphical Login?

Sep 30, 2015

I have an iMac G4 that I installed Jessie on successfully. However, when it boots, one of the last messages is:

[FAILED] Failed to start Load Kernel Modules.

Last line is something along the lines of:

fb: switching to nouveaufb from OFfb NVDA,NVMac

And then the text starts dissolving, and the entire screen cycles through different colors. I presume it is sitting at the graphical login prompt but it's not displaying correctly.

Based on some Google searches, it seems like I should be able to resolve this by editing /etc/modules but I can't get to that point. I have tried to get to a terminal using ctrl-alt-F1 through ctrl-alt-F12. No luck. I tried different yaboot options that were supposed to avoid using the video driver. No luck. How do I get the machine to boot straight to a regular text login instead of the X one?

This machine worked fine running Mac OS X this morning, so I don't think it's the hardware. What I can do.

Software :: Switch To Text Login While At Graphical Login Screen?

Jul 21, 2011

I am trying to load up the NVidia driver in Fedora 15 and am stuck. After boot up the graphical login screen comes up fine but when I go to log in I get an error message and it asks me to try to login again. I need to be able to get into text mode so I can edit some files but I do not know how to do this other that starting in multi-uder mode by editing /etc/inittab (or in FC15, editing some links in /etc/systemd/system/). Is there a way to get to text mode from the graphical loginscreen or do I need to get a rescue disk and startup in rescue mode to change files?

Ubuntu Installation :: Freezing / Rebooting When In Graphical Mode?

Jan 29, 2010

I want to switch to Ubuntu 9.10 but the computer always freezes 30 to 45 seconds after entering the graphical mode. This includes the 64bit installer, the 64bit live CD version and I even installed the 32bit version with the alternate install CD (text-mode). In all 3, I can use the system (e.g. log in, click Next) just fine for half a minute, then it crashes. It even crashes if I don't do anything.

Here are my hardware specs:
MB: Biostar TF560 A2+
CPU: AMD Athlon 64 X2 Dual Core 5000+
RAM: DDR2 800 Dual 128 bit, 2T (4GB)
GPU: ATI Radeon HD 3870

The sound and network cards are integrated but I've tried disabling them from BIOS as well as removing all hard drives and the problem persists. I have also verified the CD successfully. Note that right now I'm using SLAX from a CD as I formatted my hard drive (so at least some Linux works).

Software :: Unable To Log Into Ubuntu Using Graphical Mode / Enable This?

Aug 6, 2009

I have kubuntu 9.04 installed in my computer and I am normally using a Gnome environment desktop (though I get back to KDE or Xfce if I have any troubles with Gnome)

This afternoon I restarted my computer and since ever I am unable to log in. I press the on button, get to the partition page and select Ubuntu 9.04 and the computer shows the login page

however, once I type in my password, the computer tries to log in but then brings me back to the login page asking for the password again. I have tried to login as Xfce, Gnome, KDE, Failsafe mode and the result is the same. The only way to get through is to login through the terminal, but then I am unable to get back to the graphical mode.

Fedora :: Virtual Terminals In F15 'graphical Mode'?

Jun 5, 2011

Has anyone else here had a problem getting virtual terminals to work when booting into F15's 'graphical mode'? This is what used to be runlevel 5 in the old SysV init system, before the switch to systemd. Before F15, I could do a Ctrl-Alt-F[n] (for n=1,...6) to get virtual terminals while in runlevel 5, and this was easy to control by editing /etc/inittab.

But with systemd, /etc/inittab is no longer used, and finding where the virtual terminals get created took me a bit of time. I tracked it down to the /lib/systemd/system/prefdm.service file, which seems to stop creating virtual terminals after tty1 in order to prevent the display manager and plymouth from conflicting on that virtual terminal. I'm using the Slim display manager (installed via yum), and I only got tty1 (showing console messages), tty2 took me back to X, and there were no tty3-6 any more. I noticed from ps that there was some kind of "plymouth --wait" process running, so I killed it. After doing so, the other virtual terminals showed up. Has anyone else here experienced something similar?

It appears that /lib/systemd/system/plymouth-quit.service is not exiting properly, and this is causing the problem. This problem only occurs in graphical mode, not in console mode (what used to be runlevel 3). My first solution was to put "/bin/plymouth quit" in /erc/rc.d/rc.local, and upon rebooting that did indeed fix the problem. But eventually I just removed plymouth altogether, which also fixes the problem. It would be nice though if plymouth-quit.service just worked as it was supposed to. I'm just wondering if anyone else has seen this problem.

Ubuntu :: Start The X Graphical Interface Without Using GDM?

Jun 15, 2010

I would like to start the x graphical interface without using GDM. I may be using the wrong terms here for x. Maybe it is called xdm or x11 or something.) I have set GDM to login without asking me for a password (I am the only user of this machine.) Sometimes, it still pops up the GDM login screen and if I select "actions" "reboot" (my memory tells me that is what it was,) it will reboot without asking to login, but the fonts are all wrong. If I select "apps" "restart" and it DOESN'T ask for my login, all is OK.

I would like to uninstall GDM, and place whatever GDM uses to start the graphical interface into the /ect/rc2.d startup scripts. I know GDM does other stuff then just logs me in and starts the graphical user interface, and I think I would like to maintain some of that, but I think I would like to manually insert the startup sequence in the startup scripts. Question one, can someone tell me where to look to find out what GDM is doing now so I can attempt to replicate it?

#2, does someone know the startup script line(s) to start the x server and graphical interface without GDM? I think this has bees asked before, but it seems hard to search older posts.

Ubuntu :: Disable GDM/Graphical Login In Lucid?

May 8, 2010

It used to be that this was a service that could just be disabled in System>Preferences>Startup Services, but this is no longer the case it seems. I've tried tinkering with the runlevels in gdm.conf, but haven't had any success with it so far. I've tried commenting out the startup code in the gdm.conf as well. Also no luck.

Most of what I've found are older guides for Karmic and earlier, so if anyone has a more up-to-date solution for how to disable the gdm so I can auto-login to a terminal in Lucid

Ubuntu :: 11.04 - Can't Login After Update - Graphical Interface

I've updated my ubuntu from 10.10 ==> 11.04. Now I can't login using graphical inerface. System is loading but it stops right before I should see screen with login credentials. When I use ctrl+alt+del it's going to reboot properly, the same when i push the power button it's shutting down. System works fine in failsafex mode so I can assume there's a problem with xserver etc. Using Nvidia 9500GS.

Fedora :: F13 Not Booting To Graphical Login?

Jul 19, 2010

I recently installed fedora 13, everything was going great, now when my computer boots it shows the slash screen and then a blank screen and nothing. its been doing it the past few days, after a few reboots it'll work but i'm unable to figure out what is causing it and today it won't show the graphical login screen at all. after the Fedora slash screen the screen goes black the power button shuts it down as normal. ctrl - alt - F2 works and lets me login text wise but I can't get the graphical login to work. nor can I boot to KDE or gnome.I do have Nvidia drivers installed, normall it'll show the nvidia slash screen before the graphical login prompt comes up and that doesn't happen. I did try init 5 and it says Nvidia drivers are loaded. 3d was working just fine I haven't done anything that I can think of to provoke this.
