I have Asus X53S laptop running Ubuntu 12.04.
On my previous 12.04 installation, suspend was working.
Now, after waking up from suspend mode, all I got, was a blank screen.
What I've tried so far:
- The script mentioned here
quiet splash nolapicat
- After these, I ran
- Also, disabled, requesting password after wake up
Now, the screen after wake up isn't blank, but it's the last screen that was displayed before the suspend (probably).
Moving the mouse, shows nothing - which is, the display is dead.
Switching to tty1 (
Ctrl + Alt + F1) got me at a terminal with a working screen. From which I could use
sudo lightdm restart, which did nothing.
After that, I typed
whoand saw that my user was connected to tty7, so I changed to it, and voila, I have now access to my session, as it was before the suspend.
But with problems:
Probably the graphics are messed up. The border of the right click dialog is a thick white one (about 4mm).
My wallpaper doesn't show up, and instead I get this:
Look the wallpaper, and also, the border of the terminal window.
On a sidenote, my laptop has a Nvidia GTX520M GPU (with the "great" optimus technology).
Some related info:
- Running Additional Drivers program, I see that the version 331 of Nvidia Driver is activated and currently in use
- I remember that at my previous installation I had installed BumbleBee.
Should I try deactivating the proprietary driver, removing it, and then installing BumbleBee?
