Hello

Ok. Just for the info. The two commands I have tried did not work.
The screen went black again. Whatever that means.

But I have to say sometimes it  definitely took less time than these "600 s"  for the screen to turn black again.

Thank you Altoid for this finding and your help.
I will read the two  threads later and hopefully I will find the answer to that really annoying thing.

Ok. So I now tried the following commands:

xset -dpms
xfce4-power-manager -q

And now I am waiting to see if this will change anything at all.

Thank you Altoid for the welcome and the link.

I am reading this thread right now and later on trying to figure out if anythin of this is working for me.

Hello

I am new to the forum and just a "desktop-user".
My question might be easily answered, although I searched the forum and on the net, finding some answers but none of them worked for me so far.

I am running an old MacBookPro5,5, running devuan without any major problems for years. (Thanks for all your hard work.)

Now after upgrading to Excalibur my only problem is that my screen, while in the X environment, randomly (could be 1 minute, could be 20 minutes…) turns to black.
At this point all is still working perfectly fine in the background.

It mostly seems to happen when I do not use the touchpad or the keyboard for some time, although when watching a movie e. g. the screen also stays on.
Running a movie (mpv) seems to be the only way so far to keep the screen on.

In any other case, When I use the touchpad/keyboard again the black screen directly dissapears and everything is back to normal. Like a screensaver.

But I turned of the screensaver or any energy saving options.
At least anything I could find. It seems to be a GPU problem?

I can not  translate/understand the log entries and do not exactly know where to look at. So any help would be appreciated.

Thank you.
