I have installed today Ubuntu 10.4 LTS ..after installation the OS does not boot and just shows blank screen with cursor blinking ...any idea ..I have searched the forum a lot but cannot understand why this is happening ..re-installed twice ..

This is AMD64 bit but I am installing the 32 bit ubuntu 10.4 LTS. Please help ..otherwise I would have no choice but to go for Windows 7.

thanks
Sandy

probably a graphics issues.

I've noticed quite a few black screen threads. Worth searching...

Is that the only OS on that machine?

I'm just curious if the boot menu appears or not?

If not try holding down the Shift key right after the System/BIOS screen passes, then select to boot into the recovery mode, after it completes you'll see a list of options, select failsafeX.

If that gets you a graphic we really need to see the output of the following to determine the exact graphics chip:


lspci | grep VGA

If no recovery mode is displayed in the boot menu:


How to Boot to the Recovery Mode w/o a Menu Option

1. If you have Grub 2 set to boot without displaying the menu at all, hold the SHIFT key down until the menu displays. (In Grub it was the ESC key.)
2. Press any key once the menu is displayed to 'freeze' it. Then arrow to the kernel you want to boot.
3. Press "e"
4. Scroll to the end of the "linux /boot/vmlinuz...." line. If displayed, remove "quiet" and/or "splash". Add the word "single" to the end of the line.
5. Press CTRL-X to boot to the Recovery menu.

With so many distros to choose from:

Every distro I tried died on my machine, whether it was a 64 bit for amd or 32 bit for amd/ibm...

I get the same thing except for 1 os, the Mint9 for AMD its the only one that would allow me to boot and at that it was only the live CD

My box, AMD 64 Phenom quad core, and 7 gig ram, 2 BFG 9800GTXOC2's SLI config

now my q is why cant I get this to install UBUNTU 10.4 AMD64/Server, it says install but then fails to give me a GUI, I get command line only then it asks for Admin password, I supply the one used during install and it fails.. then endless loop..

Forgive me, I am noob to this Linux but wanted to dive right into the Server as i want to make the jump from M$ into linux and get away from the problems of Virus and spyware on MY M$ Exchange Server/ Web server...

Thanks ahead.

If you are installing the server version - it doesn't come with a gui - you need to install the gdm_desktop if you want the gui.

When you say you enter the admin password, fails and endless loop - what sort of loop? Does it reboot, or just goes back to asking for your username and password?

It just keeps prompting for a user id and password saying it fails to authenticate..

What is the command structure to install the GUI.,
Thanks

Is it something like
sudo apt-get install gdm_desktop ?
