Sometimes i get a blank screen

Asked by Anand

I am using ubuntu 12.04. I have been having some trouble with lock screen lately. While the system is locked, I sometimes get blank screen without the lock screen. So I am unable to log back in. I have to shut down the system & restart once again. While this does not happen every-time, it nevertheless keeps happening from time to time. Can anyone suggest some measure. My keyboard shortcuts or manual lock screen are both working perfectly fine.

If you wiggle the mouse, does it wake up? Is it a laptop or desktop? Does the system have a make / model?

I have the same problem on my laptop (MacBook Pro), I close the laptop and open it again and it doesn't turn on again. I push the power button and it looks like it wants to turn on, but then it turns back off. I have tried pressing every button as well as moving the mouse. The only way that I can get the computer to turn on again is to do a hard shutdown and then turn the computer on again.

It is a laptop. Yes the laptop does wake up, if you move the mouse, but lock screen is missing. This does not happen all the time but from time to time. Laptop is a HP - G62. In the previous ubuntu versions, i never had this problem...

As a workaround hit ctrl + alt + F2 (or F3) to get to a terminal, login with your user and then type

sudo killall Xorg

give your user password and re login ...

Please tell the brand of your video cards... if you don't know it from terminal type:

lspci | grep -i vga
