Error: Black screen

[trotel]

Hi, I am worried, my PC show a black screen for only 1 second, and then all is ok for a long moment, but then this happens again, and the third time my PC don't respond, and I have to reset it. It happens since I upgrade 11.10 to 12.10 (now I know that I don't have to do that).

I search in some forums, but I don't sure, some forums tell me that I have to edit the grub, other tell me about nomodeset but I don't sure and I don't spoil anything. (I AM A BEGINNER)

Initially mi PC (64 bit, core i7, 16 RAM) was dual boot (window-ubuntu) since 8 months. when the problem happen, I formatted my PC, Ubuntu to Fedora, (but not dual-boot, only fedora) and the problem continued, then I formatted all and installed Ubuntu again (all ubuntu), the problem continued, now I installed window in all the system (I remove Linux). The problem only show in Linux, I did that because I didn't know what was the problem, mi PC or the Linux, now I know, the problem is the system, Linux. I want to install dual-bott (window-fedora) but when I try to install Linux the problem appears, black sreen for few seconds.

Please, help me

Hello.
So, you had Ubuntu installed dual boot for 8 months and it was all good? Then one day out of the blue sky the screen starting blanking?

Sounds like an updated kernel or newer video drivers.

Err, wait a minute 16 RAM what? Is that a typo?

Does your computer happen to have 2 graphics cards? Perhaps a PCI card and an integrated chip?
If so, then it's likely as Mike mentioned... a newer graphics driver. You might be able to disable the PCI card in your BIOS settings, ten install the needed drivers and re-enable it.

This is just some speculation.

[MikeTbob]

Good idea, Jay. It's probably one of them new fangled NVIDIA/Optimus thingy majig.

I check, my CP only have one integrated card, not NVIDIA.

What I have to do?

Post the output of this

lspci | grep -i vga

[jayd512]

If you are unable to boot into Linux, you can use a LiveCD to post the output of the above command.

[trotel]

Ok, this is the output of "lspci | grep -i vga"

00:02.0 VGA compatible controler: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

Problem is not because of Graphics Card's driver. Have you tried nomodeset option in GRUB?

[trotel]

I read some about that but I don't understand very well what is nomodeset, I don't sure if I have to use that but please tell me What can I do for put in nomodeset mode?
