Yes, happened to me also. Kubuntu 18.04.1 Yesterday (Nov 27) suddenly (after auto upgrade of the system) nvidia stopped working (switched to nouveau, probably). Upgraded to Kubuntu 18.10 This actually made the situation even worse - stuck on 640x480 resolution. Had nvidia-390 installed at the moment, but the system wasn't using it. After some looking around, installed: sudo apt install nvidia-dkms-410 xserver-xorg-video-nvidia-410 nvidia- kernel-source-410 which made the situation look better: resolution was again native (1920x1200) and nvidia-settings launched and showed 410 driver running. But in the Steam games, it showed that llvm driver was being used. And games such as Wolfenstein New Order (uses proton wine) didn't even launch. After some more fiddling around, actually using the Kubuntu GUI tool (System Settings > Driver Manager > Nvidia > 410) fixed the situation. Apparently the GUI tool does it somehow better than installing the nvidia package manually. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1752938 Title: Upgrading Ubuntu 18.04 disables GPU hardware acceleration Status in xorg package in Ubuntu: Confirmed Bug description: I don't know which package causes this problem. The thing is ugrading Ubuntu 18.04 disables my GPU hardware acceleration. glxinfo_before_upgrade OpenGL vendor string: X.Org OpenGL renderer string: Radeon RX 560 Series (POLARIS11 / DRM 3.23.0 / 4.15.0-10-generic, LLVM 5.0.1) OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.3.3 glxinfo_after_upgrade OpenGL vendor string: VMware, Inc. OpenGL renderer string: llvmpipe (LLVM 5.0, 256 bits) OpenGL core profile version string: 3.3 (Core Profile) Mesa 17.3.3 This problem is reproducible. Steps to reproduce: 1. Install Ubuntu 18.04 daily live. I've tried Kubuntu 18.04 Feb 26's daily live(the installer in Mar 1 crashes which prevents me from installing it) and Xubuntu 18.04 Mar 2's daily live. Ubuntu is utilizing my GPU in live cd session and after the fresh install Ubuntu is also utilizing my GPU. 2. Reboot into the newly installed system, do a dist-upgrade and reboot again. Opengl renderer falls back to llvmpipe.
