Installing Kubuntu 12.04 not successfull black screen at startup

Asked by Claudio Cristinziani

Hello everybody,

I tried to make an automatic upgrade to Kubuntu 12.04 on a very stable Destop-PC System (was Kubuntu 10.04.4). When the Desktop-PC restarted the first time after installation nothing worked at all. After showing the Bios it just presented a black screen. I even could not change to tty1 or so.

So I reinstalled with the alternate CD. I use partition sda3, auto-config and cancelled it first - while on partition sda1 / sdb1 I still have a RAID with all my /home data on it which I obviously dont want to cancel.

But: After installing, same behaviour as before for a normal start. On a recovery mode I can reach the text menu, but nothing really seems to help.

Here are some details about the hardware:

Mainboard ASUS M4A87TD EVO CPU AMD Phenom II X4 955
Graphics Card ASUS NVIDIA GeForce GTX550

Because I have old monitor, it is attached to VGA output of the Graphics Card.

Can you please help me ?

Try the boot option:

nouveau.blacklist=1

Thanks

Thank You for replying,

I can do this by starting with the alternate CD. The result is that the system gets stuck. Can I add a jpg here ? (Sorry I'm new to launchpad).

Anyway would it be a good idea to install on a complete (little capacity) hard disk ?

Ok, I did the following:

Installed new (old) IDE Hard Disk 82GB and installed a new Kubuntu 12.04 alternate.
Still having big trouble, this is what happens when starting:

1) Bios comes up
2) Blinking cursor for max 1 second
3) Changes in grafic mode (I see monitor is brighter than before)
4) no Grub Splash screen, no screen output
5) Hard disc seems to do s.th. for a while and then stops
6) mouse and keyboard have power and seem to work (NUM Lock led reacts, mouse light burning)
7) change to tty1 not possible

Is there a way to force text mode on bootstrap ?

Too bad ....

... forgot to mention that I can do a warmstart with Ctrl-Alt-Del - so the keyboard defenitely works

Please try using Ubuntu 12.04 live-DVD and booting into the 'Try Ubuntu' option. If this works OK get back to us.

It took me a while, but now I can say that it doesn`t work !

After choosing the option "Start Kubuntu" the DVD-Reader works for a long while, switching in grafic mode and then back to text mode. No messages do appear, just a flashing cursor. Finally thats it. A flasing cursor. Nothing else.

Well I will now SWITCH BACK to Kubuntu version 11.10, at the moment I don't see any way to solve this problem, and I consider myself more a user than an expert. I really need my Computer working and to access my data. The system is not old but the reason for this error could be somehow the fact that I have the monitor attached to the VGA output of the graphics card.

Maybe someone (expert) should track this, open a bug or keep it in mind, in case someone else will have these difficulties.
