Can't resume after *second* suspend in Ubuntu 20.04

I used to be able to suspend/resume without issues in previous Ubuntu versions, but since upgrading to 20.04 I can only resume once. After trying to resume for the second time, the computer doesn't really resume, the screen doesn't show anything and can't even access any other terminals with Ctrl+Alt+number, so I have to force restart by pressing the restart button. Note that after I resume for the first time after a fresh restart everything works fine.

Some additional info:

• NVIDIA Driver: 460.32.03 (nvidia-driver-460)
• Linux Kernel: 5.4.0-62-generic
• OS Version: Ubuntu 20.04.1 LTS
• GNOME Version: 3.36.8

Could someone give me a hand with this? Thanks!

Solution 1:

I experience the same problem with 455 and 460 branches. The only one working fine is the legacy branch 390. Therefore you could try switching to nvidia-driver-390, if your hardware is appropriate and driver capabilities are enough for you. For instance, you won't be able to use the newest CUDA toolkit anymore. See supported NVIDIA cards.
