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.

Dual monitor suspend, one monitor does not turn on when waking up. (lemmy.ml)

Finally got my wife away from Windows and on Fedora 40 (Gnome 46).

Now, when her PC goes to suspend and when she wakes it up, one of her 2 monitors doesn't wake up.

Both are connected to HDMI ports (no dedicated video card, just the integrated card in her Ryzen 9).

Any ideas on what could be happening? I wouldn't want her to go back to Winblows over something so insignificant, but she would.

I'd probably:

make sure it can be reliably reproduced using something like systemctl suspend
try swapping the cables and see if it still happens on the same screen, or the same port
look at journald/dmesg output for the period from suspend to resume

When the screen fails to wake, are you able to get it back by powering it off, or by unplugging it? Is it X or wayland?

[–] Para_lyzed@lemmy.world 3 points 7 months ago* (last edited 7 months ago) (1 children)

Fedora 40 removes X by default (you'd have to install it yourself), so this is going to be using Wayland. Seems like they're using Ryzen integrated graphics, so at least it shouldn't be related to any of the problems with Nvidia on Wayland.

That's correct. She's on Ryzen integrated, and Wayland by default, and all info on this subject out there points to Nvidia related issues. Thanks guys.
