Comment 11 for bug 1878421

after my laptop-screen goes off (automatic locking of workstation) and i retouched it to go on again, i see some flickering on the external monitor with background-image, but it looks like there was heavy load so that login-screen wasn't displayed (see also background on internal screen)...have now switched off external monitor to get login-window again...maybe this helps to get the issue nailed down
