resume from sleep to a black screen

[lejeczek]

Hi guys.

Anybody here with similar config to mine - Ryzen 4500U in a 
Lenovo laptop with external monitor connected - gets black 
screen instead of login prompt when resume from sleep?
After recent updates on f34 it started and I only can do 
Ctrl+Alt+Del to reboot the OS, no GUI logon.

many thanks, L.

Have you tried using Ctrl+Alt+F2 to get to a text console and logging in 
there?  If that works, try this to see if your display manager is working:

ps aux | grep gdm | grep -v grep

If you're not using Gnome, substitute whatever dm you're using.  I'll 
leave the reason for the second grep as an exercise for the reader.

I definitely had that problem. Don't remember if it was limited to my 
t14amd or not. But I recall moving to a mainline vanilla kernel which 
reduced problem. But be careful with those as I went through a patch of 
problems with those as well more recently. I am nolonger using that 
laptop so I can't tell you whether by now its fixed 100% but I believe 
vanilla mainline did reduce frequency of the problems occurence.

sure your bios suspend behavior is set to linux if you have it. Hope you 
have current bios as well.

I "suffered" the same problem a while ago and even asked 
about it here on the list, then updates came, I think it was 
f33 back then, and problem "got" fixed. Couple of months 
later and it haunts again, this time in latest f34 updates.
Gee, it really seems like that "fantastic" Lenovo which some 
Fedora devels prize, of which I have been a customer too and 
for a while - quite few different ThinkPads - but know I 
begin to seriously consider a vow - Lenovo? even again and 
way! away from.
