This is my first post here, and I want help regarding my Kubuntu 12.04 and have a Dell Inspiron 15R.
I am having it since the day of its release and it was working fine until a couple of days back when I decided to get updates from muon updater.
I have kept the power settings as turn off the display after 10 minutes and when the lid of the laptop is closed. It used to work fine till the recent updates. Now after the display turns off, it doesn't turn on no matter how many keys are pressed or I try to move cursor. I can't even access tty1 by using Ctrl+Alt+Fn+F1 and so on. But as suggested on some thread, I can reboot computer by using Alt+PrintScreen+(REISUB).
However, when I login into failsafe session of Kubuntu, this effect is gone (but so are the wobbly windows and other eye candy effects which work otherwise in normal mode of Kubuntu.
I have AMD graphics card and I will run commands whichever are needed to solve the problem. Thanks!
