Description of problem: If I leave my laptop unattended for a day or so, X cannot be seen any more. It's just a black screen. I can switch virtual consoles and use those, but switching back to X does not work. I can only kill X and login again. Version-Release number of selected component (if applicable): gnome-shell-3.16.3-1.fc22.x86_64 How reproducible: Every Monday morning Additional info: journalctl shows me loads of these errors: gnome-session[1419]: (gnome-shell:1468): Cogl-WARNING **: Failed to set crtc mode 1920x1080: Permission denied gnome-session[1419]: (gnome-shell:1468): Cogl-WARNING **: Failed to set crtc mode : Permission denied gnome-session[1419]: (gnome-shell:1468): Cogl-WARNING **: Failed to set crtc mode : Permission denied

This message occurs before the very first error above: gnome-session[1419]: Window manager warning: Failed to set power save mode for output eDP31: Permission denied Interestingly this happens a day and a half after I stopped using my laptop for the weekend.
Created attachment 1077941 [details] messages log file containing error messages and the restart of gdm Here is the (trimmed down) log file that shows the "failed to set crtc mode" bug.
Disabling power saving for the screen is a workaround that I tested and works.
Tody,I have encountered this problem. First, I open a tty, and executing: $ sudo journalctl -f and restart GDM, print as follows: Dec 03 22:03:22 lx-pc gnome-shell-wayland.desktop[6438]: gbm: failed to open any driver (search paths /usr/lib64/dri) Dec 03 22:03:22 lx-pc gnome-shell-wayland.desktop[6438]: gbm: Last dlopen error: /usr/lib64/dri/i965_dri.so: cannot open shared object file: No such file or directory yes, I not found i965_dri.so in /usr/lib64/dri/, so, search this file and install it: $ dnf provides '*/i965_dri.so' Last metadata expiration check performed 5 days, 0:50:16 ago on Sat Nov 28 21:50:24 2015. mesa-dri-drivers-11.0.6-1.20151122.fc23.x86_64 : Mesa-based DRI drivers Repo : @System $ sudo install mesa-dri-drivers and solve it.
Thanks Xi Lu. I am running Fedora 23 now and already have that package installed. I will re-enable power saving for the screen to see if the problem has gone away.

I think you accidentally delete some library. yes, I accidentally delete `mesa-dri-drivers` package, so GDM don't work. You can using journalctl view log info ;-)
