Ubuntu 21.04 cannot resume from suspend [duplicate]
Solution 1:
I suspect that your problem is related to the latest NVIDIA update, which installs nvidia-driver-460
. There is currently a bug with this version and some versions after it. You can subscribe to the bug here: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-460/+bug/1911055
You can workaround the issue until the bug gets resolved by downgrading the NVIDIA driver to a previous version. Follow these steps to downgrade to nvidia-driver-450-server
:
-
Open Software & Updates and go to the Additional Drivers tab.
-
Select
nvidia-driver-450-server
(Using NVIDIA Server Driver metapackage from nvidia-driver-450-server (proprietary)).You may try other drivers instead of
nvidia-driver-450-server
, if you wish, and stay with the one that works best for you. -
Click Apply Changes and wait until the changes are applied.
-
Restart your system.
Suspend should now work as expected!
Solution 2:
I had the same issue on an Acer Aspire laptop running Ubuntu 20.04 with NVIDIA. I was using the default driver (nvidia-driver-460
). I then tried nvidia-driver-450-server
and still didn't have any luck. Then I tried nvidia-driver-418-server
and it worked.
Here is my Additional Drivers tab in Software & Updates:
My advice: keep rolling back the driver and testing until you find one that works.
- Open Software & Updates → Additional Drivers tab.
- Select
nvidia-driver-418-server
. - Click Apply Changes.
- Reboot system.
- Test suspend.
