Comment 0 for bug 1772542

my box is 18.04 (was 17.10 installed; standard Ubuntu with MATE & XFCE desktops added)

I sleep my XFCE (xubuntu) machine rather than turning it off at night.

Today as with yesterday morning, instead of getting the locker-screen after hitting the power-button to wake my machine, i get a blank screen with a RADEON two-line text message top left on screen which appear only momentarily as screen is erased and I get the login/greeter screen.

(it's happened 4-5 times, but does NOT happen every time)

I can login fine, but my xfce session is new.

I have grep'd for the message I see (yesterday & today), but can't find it as i usually recall little but the radeon word...

sudo lshw -C video
