Blackscreen after boot ubuntu 12.10

rated 0 times [ 0] [ 0] / answers: 1 / hits: 839 / 1 Year ago, thu, april 20, 2023, 7:21:48

I have a dual boot (w7, ubuntu 12.10 ) laptop. Everything was OK since some weeks. Now I am unable to boot my ubuntu 99 times of a hundred.

The process start with the bios settings and all, then grub screen shows up normally ( with all the correct options ) then, when I choose ubuntu option screen turns black ( with back-light ) and that's all ...

I have tried with Ctrl+Alt+F1 to try to drop to the root console but nothing happens ...

IF I try enough times the logging screen shows up and from there everything goes smoothly.

This is my first serious issue with Ubuntu (and I'm using it since 8.04 version ) and I have no idea where to start investigating ...

This error has made my computer unusable so please, I need help ...

Thanks for all in advance.

P.S.:Since I updated to 12.10 while I am working normally from time to time a window pops up with a "System program problem detected". I haven't found a way to get more details about the problem and after reading some web sites seems something "normal" ( or at least common ) but I mention it here just in case.

well it seems that the problem is the kernel version.

Last kernel update was 3.5.0-27 and it seems it has some problems with the video drivers of multiple graphic cards.
After reading this two bug reports I thought the kernel could be the problem and try to boot with the 3.5.0-26 ( thanks good that ubuntu stores the last used kernels just in case ), no problem since then. I have been able to boot my laptop 10 times from 10 tries so I think the problem was the kernel.

I do not know what the problem was exactly and the bug reports are not solved yet, so until then I will not update my system to the 3.5.0-27 kernel version.

Thanks for your answers
