I opened Blender 4.1.1 and it couldn't find the GPU. I had to switch to nouveau, reboot, switch back to nvidia-driver-535(proprietary, tested), and reboot and Blender 4.1.1 could find the GPU again. I did the same on my computer Custom PC i5-12400F Arc A750 + intel's Ubuntu Repo was on Ubuntu 23.10 Did an update-manager -d to 24.04 and everything seemed to go smoothly too. I opened Blender 4.1.1 and it couldn't find the GPU. I tired older versions no luck. reinstalled all the packages from intel no luck. this might be partly an intel issue so I posted in their community too https://community.intel.com/t5/Intel-ARC-Graphics/Blender-can-t-find-my- GPU-now-upgraded-to-Ubuntu-24-04-from-23/m-p/1593065#M13990 ** Affects: update-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2063955 Title: 23.10 to 24.04 upgrade needed to reinstall of GPU drivers for Blender to see them To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/2063955/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
