I recently installed Mint 17.3 (Rosa) with MATE on a T60 laptop.
The installation as such went without any notable obstacles.
If I return to the computer after a while, then it has become impossible to log into through the terminal. It doesn't react on mouse movements - nor on any keys on the keyboard.
In fact, this occurs already if I hesitate slightly more than 60 seconds before I login.
(sshd is installed, and it is no problems to log in that way. But I do not know HOW to change the relevant parameters, or WHERE to find them, so in order to use the keyboard or see something on the screen, a shutdown or reboot is what remains for me.)
This all seems very much as an obvious bug to me. But being inexperienced and forgetful, I do not really know where to search for a solution or (even less) where to file a bug report.
I've tried with the search function here at LQ, and also with Google search too... but I do not find anything useful.
...alternatively: I do not understand enough to judge what to look after.
I've changed the (default) screensaver from "Blank screen"
to "Floating GNOME",
and put the time to 30 minutes for when the computer is to regard as idle, but that didn't solve this problem.
I did also uncheck the alternative "Dim display when idle"
in the Power Management Preferences.
The other parameters there are:
Put computer to sleep when...
When laptop lid is closed:
Put display to sleep when...
So, now the question are:
- What to do?
- What possible workarounds should I try next?
- Where do I check if anyone already has filed a bug report?
