I know there can be many reasons for this, but currently my Toshiba satellite laptop is not showing the display. It's been running ubuntu in various versions for 2 years now. The last install I had was running pretty hot, I couldn't manage to tweak it for some reason as well as I had in the past. But now the computer seems to be functioning, but most of the time the display never lights up at all, not even BIOS. however the one out of approximately 20 times it works, it works 100% normally.
Please, what could be the problem? I know it's probably not an ubuntu issue, but need help? Is it a CPU issue? why does it work occasionally?
