Hardware: Dell XPS 17 laptop 9710 (brand new)

Operating System: Ubuntu 21.10

Processor: 11th Gen Intel® Core™ i7-11800H @ 2.30GHz × 16

Graphics: Mesa Intel® UHD Graphics (TGL GT1)

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation TigerLake-H GT1 [UHD Graphics] (rev 01)

Problem: when the laptop goes to sleep, I cannot wake it up. Neither opening the lid nor tapping the power button will wake it up.

Workaround: hold the power button for 40 seconds. After doing this, I can tap the power button and get it to reboot. Unsatisfactory because I lose any open applications.

For me this command worked (found from this answer):

sudo ubuntu-drivers install

I have a Dell XPS 15 9510, on which I installed Ubuntu 21.10.

I had the same problem from the beginning: when making the laptop sleep, it displayed a black screen, and never woke up. The only way to get something was to press the power button during 10 seconds to force the computer power off.

I had also another problem: most of the time the computer was not shutting down. When asking to shut down it stopped to a black screen with "Ubuntu" displayed. Same thing here: the only solution to shut down was 10 seconds on the power button.

I think the problem was that the NVIDIA driver was missing (I have a GeForce RTX 3050 Ti Mobile, in addition to the Intel UHD Graphics). Before the command I didn't have anything in Software & updates -> Additional drivers. After the command I had several NVIDIA drivers, with the first one selected for me.
