Ubuntu

Can't Login

Asked by Haseeb_GP

I downloaded Gutsy Gibbon Tribe 2 image and trying to run it on a VMware Workstation 6.0 but theres a problem. For some time it shows splash screen but then it shows a black screen for some time and then logs out and again logs in and keeps on repeating the same process again and again. Can you tell me what might be the problem and how can i solve it?

the blackscreen shows

Try to reboot to Rescue mode. If the problem still continues, press Alt+Ctrl+F1, login and then try

sudo dpkg-reconfigure xserver-xorg -plow

Accept all default answers, but the driver and resolution. I don't know if the vmware graphical driver is included in Ubuntu, but if it isn't, select vesa. For resolution, try to enable lower ones (1024x768). Maybe this helps.

Then try to start again Gnome with

sudo /etc/init.d/gdm restart

In vmware, to access the tty consoles you can't use Alt+Ctrl+F1. My bad, sorry. To access them you must press

Alt+Ctrl+Space and without releasing the Alt+Ctrl keys, press F1

That should put you on a tty console of the virtual machine. Try it this way.

The "Rescue mode" I've talked earlier was in the installed ubuntu, not the LiveCD. If no options are given at boot, or you don't see them when the computer boots, you must press the Esc key to access the Rescue mode in GRUB boot. When GRUB menu is disabled, you must press the Esc key right after the POST boot, i.e. when the output of the data about your motherboard ends and before the splash screen of ubuntu starts (sometimes there is no splashscreen, only the output of init/upstart, the "blackscreen" you posted previously). So be quick on this (keep hitting Esc) .

Then, in rescue mode, try the "sudo dpkg-reconfigure xserver-xorg -plow" command on the tty1 console. I think this must be done in the tty console, not in the terminal that appears instead of the Gnome login. If the "sudo /etc/init.d/gdm restart" doesn't restart Xorg, try rebooting (type "sudo shutdown -t now") to see if works.

You can boot the liveCD in a "safe graphic mode", just by selecting the second option on the first menu it displays on boot.

Hope this helps.

Booting in using "safe graphic mode" did the work.

Thanks!

My problem WAS that every time I touched anything on the screens & graphics i got a black screen on restart.

That was solved by doing what I rode on another forum:

| On your grub menu, before boot, hover over the Linux version you want to run, hit e, then go to the second line and hit e again. Scroll to the end, make splash nosplash, and remove quite. Hit
| enter, and then hit b to boot it.
|
| Works for me. You can also set these options in your /boot/grub/menu.ist

that is replace "quite splash" to "nosplash"

that made I got stuck on the "running local boot scripts (/etc/rc.local)"

but if you press enter you can log in and then make:

sudo dpkg-reconfigure xserver-xorg -plow

that rui bernardo suggested on this thread (thanks!). Follow his steps and voilà! everything back to normal.

apparently it keeps swithching the screen resolution to the wrong one. But if I edited it directly by
sudo nano -w /etc/usplash.conf
it didn't work.

thanks everyone!

Hello!

Unfortunatelly, I have the same problem :(

I installed ubuntu 7.10 on my computer but I cannot log in. It stops at

running local boot scripts (/etc/rc.local)

I did what Rui Bernardo said. After that, Gnome is terminated, and right after it starts again. But nothing else happens

Please help me!
