Since a few months I have GTK 3.22 on my gentoo box, and so I tried to log in with Wayland support from the graphical GDM display manager. Works all fine. But one problem is, that the display is shut down after a few hours sometimes. Initially I had the impression that wayland does that shut down. But the Gnome screensaver related settings are disabled, and I never saw that shutdown without wayland. My current impression is: Monitor shuts down after some hours to save energy, wayland display driver detects this and shuts down the display driver in PC to save even more energy. I think that is the right idea, as the same seems to occur also when I power off the monitor while the PC is still running. Getting the display on again is really hard. After much testing a found one method that works most of the time: Ensure monitor is powered off. Then press Ctrl-ALT-F3. Wait about one second and switch on the monitor. Most of the time I can get a visible terminal 3 this way and can switch back to Gnome GUI with Alt-F2. May there exist a better solution? A secret wakeup key? Or useful search terms for search engine? Monitor is connected via USB-C to PC, PC is Intel NUC skull canyon. PS: For my previous post, I really forgot to give the explicit link to the git repository. It is https://github.com/StefanSalewski/gintro Fortunately that link was contained in the git clone expression already. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
