Hi, I just installed CentOS 7 with GNOME on my new Dell Latitude E6230 laptop. So far, everything runs nicely. I just have one problem with the GNOME lockscreen. I launched the OwnCloud client and started to synchronize about 20 GB of data from my OwnCloud server. During the sync, I left the laptop unattended. After about 15 minutes, the desktop was replaced by the lockscreen, as it should. As soon as the OwnCloud sync was finished, there was a corresponding notification that displayed on the lockscreen. Usually I hit [Enter] to exit the lockscreen by providing my user password. Only this time nothing happened. The lockscreen seemed to have frozen with the notification in the center. To exit it, I had to hard reset my laptop. Anyone knows what could be the problem here?
