I am running Xubuntu 14.10 on a desktop and use LightDM. As I said in the title after I turn off my monitor (with the computer already on) and then turn it back on again there is no input from my computer. I can get the display to show again by blindly typing super + t to get a terminal and then xrandr --auto
. Also, it can also be solved by sudo restart lightdm
after going to tty1
, but this resets the session.
However, if I had locked the computer with light-locker prior to turning off the monitor, the background on the greeter is just changed to the default and I can login.
The monitor is connected via HDMI, and I am using Intel integrated graphics. Is there any way to prevent this problem?
