Hi all! I'm running an up to date Centos-7 on my Acer Aspire One netbook. have been for, well, ever since C7 was released. Just had an event today that also happened 2 or 3 times with earlier systems installed, but I never pursued it. What happens is that suddenly while working away on the desktop the display suddenly goes black... not black as in turned off, I can see that the backlight is still on, but no image is displayed. Nothing I can do fixes it except a reboot. I've tried CTRL-ALT-BKSP, CTRL-ALT-DEL, alt+printscreen+r+e+i+s+u+b. none of them do anything noticeable. I've been looking at system logs and don't find anything that gives me a clue what is going wrong when that happens. neither dmesg, /var/log/Xorg*, nor /var/log/messages contins much. I've tried digging thru "man journalctl" and ultimately reading thru the output of journalctl with no arguments. Can anyone of you provide further hints on what I should be looking for or at? thanks!
