display problem after locking screen

Postby ktat » 2020-07-11 03:09

I've got an old hp pavilion g series laptop with Debian 10 installed.

I'm not sure what the issue is, but I'm assuming that it relates to X. I've had a look through the forums, however can't find anything like the problem I'm experiencing.

Every time I login after closing my laptop the display looks like this:

I have my power settings to lock my screen when the laptop is closed. This also happens when I start up the game 0 AD. My fix at the moment is to log out and then log back in. Obviously, it would be great if I didn't have to do this every time I closed my laptop.

Graphics hardware & driver? Messages in ~/.xsession-errors or the systemd journal?

Graphics hardware and driver (not sure how to id the driver):
Code: Select all
inxi -Fx | grep -A 5 "Graphics:"

content of ~/.xsession-errors (rather than paste a wall of text, I've just posted what I think may be most relevant. If something important is missing, let me know)

My apologies, I'm only slightly familiar with bash and the inner workings of linux. I'm not sure where/how to access the systemd journal.

I'm not sure where/how to access the systemd journal.

Why not educate your self a little ?, all you need to do is ask your favourite search engine : "how to access the systemd journal."
You will find all kinds of wonderful documentation, this: https://www.linode.com/docs/quick-answers/linux/how-to-use-journalctl/ is one of many educational documents.

I will agree, perhaps could be more clear, to be honest I am not sure, either I think they mean the
Code: Select all
# journalctl

command, note the # is not part of the command, it means you must use sudu or su- to become root.
To learn more about the command 'man journalctl' or a search . "How to use journalctl"
Please Read What we expect you have already Done
