Fedora 34 boot stuck as cursor blinking

I upgraded my Fedora 34 system using dnf upgrade and rebooted the system. After I enter the encryption password the screen goes black and blinking cursor appears on the top left corner. I can only boot into the system if i enter “nomodeset” at the end of the linux line in the grub menu boot editor. This boot messes up my resolution and there are no animations also. How can i fix this ??

These are the important logs I could get from the Logs app.
This is the only OS present on my computer.


Seems you are hit by the same issue as above.

Hi all,

I am having the same issue. After the update, the computer boots up, after entering the password the screen goes blank with the cursor blinking on the left upper part of the screen. From time to time the screen flickers as it tries something and fails, like it’s in a loop.

Not much experience with Fedora and don’t know what to do, sitting like a duckling in front of the screen, hoping to find a solution.

I found something “nomodeset=0” managed to type it after vigorously pressing letter “E” and nothing has changed, only there was a jumbled up screen for a second or two and black screen again with the cursor winking at me.

Your posts here are 12 months after the last earlier post in this thread. Fedora 34 is EOL in about a month.

What version of fedora are you using? What hardware?

Please start a new thread with your issues and enough info so we may be able to assist in that thread.
