CARLA UE5 + Ubuntu 22.04 + GeForce RTX 5090 graphics card

[aiyan327]

This thing has haunted me for weeks so I guess it would be a good idea to share the solution.

Problem: this MSI machine with RTX 5090 is too new and I couldn't install Ubuntu 22.04 on it. + I do not know how to build CARLA UE5 in Ubuntu 24.04.

My machine specs:
Hardware model: Micro-Star International Co., Ltd. US Desktop Infinite RS
Processor: Intel Core Ultra 9
Graphics: NVIDIA GeForce RTX 5090

1st failed attempt: made a bootable USB drive with Ubuntu 22.04.
After choosing "try or install ubuntu", the screen was pure black until I forced shutting down.

Solution

• Install Ubuntu 22.04 (I got this instruction from our university IT office and many thanks)

On a linux machine:

1. Download the latest Ubuntu 22.04 LTS ISO
2. Open terminal and run sudo apt install cubic
3. Launch Cubic >select a folder with for this project, choose the Ubuntu 22.04 LTS ISO
4. Inside the cubic terminal run the following commands:
   i. sudo apt update
   ii. Decide which kernel you want to install
   A. For latest supported kernel: sudo apt install --install-recommends linux-generic-hwe-22.04
   B. Manually install new kernel (6.8) from ubuntu kernel ppa:
   sudo add-apt-repository ppa:cappelikan/ppa
   sudo apt install mainline
   sudo mainline--install-latest
5. sudo ubuntu-drivers autoinstall # Install NVIDIA drivers
6. (optional: remove Nouveau to avoid boot issues) i. echo "blacklist nouveau" >> /etc/modprobe.d/blacklist-nouveau.conf ii. update-initramfs -u
7. (optional) Modify GRUB defaults i. Remove 'quiet splash' ii. Add 'nouveau.modeset=0'
8. Click 'Generate ISO'
9. Flash the newly created ISO to a flash drive and boot it up from the PC you in which would like to install.

• Install the correct NVIDIA driver

The auto installed NVIDIDA driver 570 couldn't work. It only showed the Intel integrated GPU in the system settings. So next step is to manually install the correct driver.

1. Find the driver version:
   In this link: https://www.nvidia.com/en-us/drivers/
   Type the GPU version in the "Manual Driver Search" bar. In my case, it was "GeForce RTX 5090 Linux 64-bit".
2. Download the driver
3. Remove the current driver
   sudo apt purge nvidia-driver-570 nvidia-dkms-570
   sudo apt autoremove
4. Stop display manager
   sudo systemctl isolate multi-user.target
   Then just login using your username and pin
5. Install the downloaded driver installer
   cd Downloads
   sudo ./NVIDIA-Linux-x86_64-570.169.run. (If the version you downloaded is different, change the filename)
6. Restart the machine
   reboot
7. Build CARLA UE5 using the official tutorial: https://carla-ue5.readthedocs.io/en/latest/build_linux_ue5/

You’re welcome :)

I followed your steps but it still didn't seem to work. I'm using the 9800x3d + 5070ti

[aiyan327]

I checked on Nvidia's website, for your 5070ti and linux system, the compatible driver version should be 570.172.08. Can you try downloading this one instead?
I didn't include the third party software, but that shouldn't matter. It should be fine if you include them.

[Gwance124]

Thanks, I'll try downloading them later today. Also the whole time (starting at installing ubuntu) you're just using the hdmi or displayport from your gpu to display it and not switching to motherboard display correct?

[aiyan327]

Yes, it's the DGPU port.

[Gwance124]

Still doesn't work. I get no display from gpu, but if I switch to igpu and type nvidia-smi it shows that the drivers are installed

[aiyan327]

umm that could be because your system is now prioritizing the integrated gpu for display. There should be some solutions online about how to switch to another one.
