Do you know _how_ recently it stopped blanking? A week or so ago, but I'm not sure exactly what I might have installed or updated to cause it. There are recent kernels, but no recent nouveau driver. > > I've > > modified the screen-blank settings, to no avail. > > Same here. > > If I switch to a > > virtual console, blanking works fine. > > Hmm, I get the same behavior in a virtual console as I do in X, that is > on monitor suspended one remains on.

No, wait. It worked the first time, then the next couple of times the screen flashed off and on. Then it worked fine again. (Actually, there's a very slight ghost image.) Meanwhile, when the unit is docked, the external screen blanks, but then I can't get it to come back on. If I switch to a VC, the external screen remains blank. If I undock the machine, the built-in screen remains dark in X and in VC. > > When I do it my monitors appear to shut down but then one turns back on. > > Just for grins, I tried to install the presentation-mode extension to see if it offered a setting to change, but the new menu option doesn't show up. This seems to be par for the course with extensions. The hot right corner extension doesn't work and the weather app doesn't show up. There's apparently been no progress on porting those extensions to recent versions of gnome-shell. -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
