New question #704179 on Ubuntu-Certification: https://answers.launchpad.net/ubuntu-certification/+question/704179
I recently bought a Dell G15 5521 laptop. This has an Intel i7-12700H CPU, NVidia Geforce RTX 3060 6GB video card, 32GB RAM. I want to use this as a home machine and for software development. It comes with Windows 11 Home pre-installed. I have installed XUbuntu 22.04 as a dual-boot. The basic XUbuntu desktop (Xfce) is now working. According to these two links, I think that Ubuntu should be working (certified) on this spec: Dell G15 Special Edition 5521: https://ubuntu.com/certified/202112-29779 Dell G15 5520 (RTX 3060): https://ubuntu.com/certified/202111-29683 However, I do note that these say: Pre-installed in some regions with a custom Ubuntu image that takes advantage of the system’s hardware features and may include additional software. Standard images of Ubuntu may not work well, or at all. Initially, I had problems with random temporary freezes, but after some googling, I seem to have fixed this by adding this to the kernel command line in the Grub config: ibt=off acpi=off However, I'm still having some significant issues. Using the HDMI port. Nothing seems to recognise the HDMI port for an external monitor. This is a blocker for my expected usage. I did some googling around this, found various suggestions about installing different NVidia drivers, but not clear on details. I tried using Software Updater => Settings => Additional Drivers. This was originally set to use X.Org X.server -- Nouveau. I changed this to use "NVIDIA driver (open kernel) metapackage from nvidia-driver-525-open (proprietary, tested)" This doesn't seem to have helped to recognise the HDMI port, so I have currently reverted this back to Nouveau. The system freezes on shutdown; it never completes, and I have to hold down the power key to complete the shutdown. I am an experienced Linux user, though not experienced in diagnosing desktop issues such as these. I have been running XUbuntu on my previous laptop for many years. It generally "just works", and I have not had to dig in to diagnose display issues like these. I have also used Linux for professional software development. My questions: I'm currently on XUbuntu 22.04. Am I likely to have better luck if I upgrade to 22.10? How to diagnose the HDMI behaviour? Again, which logs to look at. Various suggestions tell me to try a plethora of different NVidia drivers. Which ones are relevant, where should I get them from, if not just from the standard XUbuntu sources? In the Ubuntu Software & Updates settings GUI, under Additional Drivers, it lists 8 different NVidia drivers, each with different numbers associated with them. Are these version numbers (bigger is better), or are they intended to match the hardware? If the latter, which should I choose on my system (NVidia Geforce RTX 3060 6GB video card). If I really need to use the exact kernel which was used in the certification steps (5.14.0-1011-oem kernel), where do I get that from and how should I install it? uname -a currently shows: Linux DellG15 5.15.0-56-generic #62-Ubuntu SMP Tue Nov 22 19:54:14 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux Any suggestions on how to diagnose the shutdown issues? Which log files should I be looking at? Which settings may be relevant? What else should I be investigating?
