I made a test with the standard 4.15.0-62-generic kernel. The result is the same, and I add that the laptop takes 3-4 minutes to pass from the login screen to a ready desktop.
I attach a dmesg text obtained with the older kernel. ** Attachment added: "dmesg_4.15.txt" https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1843573/+attachment/5288489/+files/dmesg_4.15.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1843573 Title: Repeated kernel DRM error messages and very slow boot on Dell Vostro 1400 Laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1843573/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
