http://ubuntuforums.org – This problem always happend to me, i tried the ubuntu alpha3 and now the kubuntu version. iI have a kubuntu alpha 3 cd, booted from it and at login the laptop rebooted. I tried again, Press F6 at grub menu and chose acpi=off noapic and nomodeset. After this i booted and installed kubuntu successfully. I started in safe mode and made all the updates, now after reboot i get that reboot at login or if i try to login in fluxbox after a few seconds after fluxbox loads. I tried using acpi=off noapic and nomodeset, i tried xforcevesa and even creating a xorg.conf and set vesa insted of radeon. (Hardware)

Stories similar to [all variants] Lucid reboots at login or imediatly after login

I just upgraded to KDE 4.8 via ppa. Now when I want to login at the login screen, KDE does not accept my password anymore. But I can login in terminal/console.

What can I do?

Can I start the desktop gui at least from Konsole? But how? I don't know the console command.

Please, help!

I have installed Kubuntu 12.04 LTS.By mistake I removed default login screen (Ariya). It is showing this message "Cannot login /user/shared/kde4/apps/kdm/themes/ariya" now I am not able to login to previous GUI.It is getting login in command line.How to resolve problem?

I've downloaded several ARM (armel - omap4) prebuilt/preinstalled images: ubuntu precise, kubuntu precise and older ones, but always having the same problem. I can not login.

I installed Kubuntu today and had this problem: Dual boot launched, it asked for login and pass, I gave it and it stops at a black command line screen that has my computer name hk@hkP5K-WM:~$ I types startx and it says: FATAL: Error inserting nvidia_173 (...): No such device

I then booted with nomodeset but although it booted normally, when I clicked with my Microsoft mouse there was nothing

ok, my first major upgrade and I chose the preupgrade path (i also tried preupgrade-cli).

The system downloads the version 17 and then I reboot the server to "upgrade to version 17" (after grub loads).

Then another 20 minutes when it updates 1466 packages.

Hi, I have used older versions of Ubuntu previously with no problems, but recently installed Kubuntu 12.04 onto my netbook, and set the option to login without username/password prompt.

as you see on the second files header, you should not manually edit this file.

[ubuntu] Cannot Login anymore 1 year 19 weeks ago

Hi,

I have wubi installed. It was working sluggish so I rebooted. Now, in the login screen I get a message:Install problem The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact your computer administrator And it is impossible to login. I can always login in console mode as root (recovery).

When I use the console without the X server, either by not starting Xorg or by pressing "CTRL-Alt-F1", the user prompt looks strange, and I can't seem to get it back.
