I recently switched from Zorin OS to Fedora 43 (KDE Plasma 6) on my Lenovo ThinkPad T480 (i5 8th Gen), and I’m running into a frustrating issue.
Whenever I put the laptop into sleep mode, the screen goes black and never wakes up. Pressing the power button or any key does nothing. Even holding the power button doesn’t force it off. The only way to shut it down is by using the emergency reset hole to disconnect the internal battery.
After that, it boots normally—until I try sleep mode again. I also tried shutting down instead of sleeping, but the shutdown process freezes at the Lenovo logo with the Fedora spinner below it.
For context:
• I’m on Fedora 43
• Using KDE Plasma 6
• Hardware: Lenovo ThinkPad T480, i5-8th Gen
• I reset BIOS to default settings yesterday
When I close the screen of my laptop (a MacBook Air) onto the keyboard, it goes into sleep mode, but I can’t always restart it: the screen remains black and does not display the password prompt.
However, if I lock the screen (Super+L) or wait a long time for the computer to go into sleep mode, I can always get the password prompt.
I just upgraded from Fedora 41 to 43 and I’m hitting the same issue here: after suspend, the laptop sometimes comes back to a black screen and does not respond, so the only way out is a hard reboot.
What makes this especially frustrating is that I ran into similar resume/wake issues before when trying Wayland, and back then the workaround was simply to stay on X11. With Fedora 43, GNOME users were moved to Wayland-only, so for people who avoided this exact class of bug by staying on X11, that fallback is now gone:
So from the user side this really does feel like an old problem still exists, but the escape route was removed anyway.
Might be related to NVIDIA drivers (using noveau right now) or kernel related.
