Hi, I apologize for not responding, but I had an hard month at work.
Thx a lot to you all.
Two days ago was released 24.04.3 and I made the upgrade so I realized that I was wrong: my laptop was 24.04.2. The upgrade to 24.04.3 was quick and smooth, but surprisingly, after the upgrade, the kernel still was 6.8, so I manually installed 6.14.0.27 and now everything is ok.
Thank you again.
