Dear Maintainer,
It is a PC without hibernation, a tower and a screen, not a laptop.
After the last update from 1:7.3.0-1+b1 to 1:7.4.0-2, if we do not connect before the screen is put to sleep (about 10 minutes), the system becomes inaccessible. Unable to connect with the keyboard or by SSH, you need to reboot the machine with the button. Alt-Syst-b does nothing.
By cons, if you connect there is no problem, you can leave the PC without activity it does not freeze.
There are no traces in the logs.
Regards.
