From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

(partially solved, will update when completed) Please help with an xfce/powerup bug: black screen after suspend/hibernate (programming.dev)

MX Linux, Xfce 4.18

Closing the laptop lid suspends the system, opening it resumes it, but the screen is black. I'm guessing it's related to powerup because suspending through the logout menu and systemctl suspend both work as expected. When it's black, switching to a different tty works, as well as C-M-Backspace to logout.

Same results with both lightdm and sddm, when replacing suspend with hibernate, and I've tried a few solutions like disabling lock on sleep.

Seems like this issue has been around for years, but had a whole bunch of different causes since every other thread has a different solution.

XFSETTINGSD_DEBUG=1 xfsettingsd --replace --no-daemon > /tmp/xf.log 2>&1

ps -ef | grep -E 'screen|lock'

xfconf-query -c xfce4-power-manager -lv

dmesg, cleared it before trying to suspend

updates:

I'm not seeing a black screen, instead it turns on the display and then turns it off.

Additionally, I tried closing and opening the lid a few times, and it woke up correctly.

I tried it in i3wm with the xfce power manager to suspend after closing the lid. It woke up correctly 10 times in a row.

Solution: start an xrandr config and the monitor turns back on.

Be aware that you are having problems with legacy software being completely based off unmaintained XOrg.

It might just be a driver problem, but if XOrg is the problem, thats not solvable soon.

unmaintained XOrg

hmmmmmmm... It's just not introducing breaking changes all the time like wayland.

And I'd definitely not call xfce legacy as it's in active development, but its focus has always been on stability over introducing new features.
