when I press Ctrl+Alt+F2 terminal appears and works fine but while Ubuntu login screen is booting up this issue appears

iwlwifi .. :BIOS contains WGDS but no WRDS

And my Ubuntu 18.04 is not booting up in the start. I haven't found solution to this problem. Anyone knows what to do?

  • Answering the question in a comment as I do not have enough reputation to post an answer! I was facing the same issue on my Ubuntu 18.04 and the reason for the same was gdm3 service in stopped state. The screen following the error screen allowed me to login using my username and password on a CLI (instead of GUI) and then running the following command started the GUI as usual - sudo service gdm3 start Commented Oct 8, 2021 at 12:54

See Ubuntu not booting due to iwlwifi error-BIOS contains WGDS but no WRDS

In a nutshell:

  1. Boot into recovery mode

  2. Choose Enable network, and wait for the process to complete.

  3. Choose Drop to root shell prompt.

  4. Reinstall the desktop manager packages with apt install ubuntu-desktop

  5. Then reboot.

The boot process should progress as usual, and you should be able to log in.


I had the same problem.
I solved it by going to Recovery modeEnable network. In Repair broken packages input:

$ apt update  
$ apt dist-upgrade
