Hi Daniel, We continued debugging the issue further, and as you suggested, we were able to identify the root cause. After installing the Xorg server which as pvr support, we successfully launched GNOME-Shell using Xorg with GPU acceleration by running startx and we are able to run gnome-shell.
However, we installing LightDM and make use of complete gnome-session and configuring it to use Xorg for a multi-user environment, we started observing inconsistent behaviour. While LightDM is sometimes able to launch GNOME sessions with hardware acceleration successfully, other times it fails to do so, and GNOME falls back with the error message: "Oh no! Something gone wrong." We also noticed that after installing the Mesa drivers with pvr support, GNOME sessions occasionally launch successfully via LightDM, but not consistently. This intermittent behaviour is causing usability issues. Additionally, we observed errors in the logs using "journalctl --user -b | grep gnome-session" , indicating that GNOME is still attempting to load software rendering binaries, as shown in the following log entries: Apr 21 11:49:23 Ubuntu-riscv64 gnome-session[2090]: gnome-session-binary[2090]: WARNING: App 'org.gnome.SettingsDaemon.XSettings.desktop' exited with code 1 Apr 21 11:49:23 Ubuntu-riscv64 gnome-session-binary[2090]: WARNING: App 'org.gnome.SettingsDaemon.XSettings.desktop' exited with code 1 Apr 21 11:54:58 Ubuntu-riscv64 gnome-session[2484]: gnome-session-check-accelerated: GL Helper exited with code 256 Apr 21 11:54:58 Ubuntu-riscv64 gnome-session[2486]: libEGL warning: MESA-LOADER: failed to open swrast: libLLVM-14.so.1: cannot open shared object file: No such file or directory (search paths /usr/lib/riscv64-linux-gnu/dri, suffix _dri) So I am unable to make sure what to makeup with this issue, could you please provide us more suggestions or feedback here.

Initially, we tested this on Ubuntu 22.04 LTS, but after receiving suggestions from the GNOME forum, we decided to switch to Ubuntu 24.04 LTS. Since upgrading, we’ve noticed significant improvements, and GNOME is running more smoothly than expected. However, the graphics configuration still shows “Software Rendering” instead of utilising hardware acceleration. Despite configuring the Imagination GPU, we are unable to enable hardware acceleration for GNOME, which is impacting 3D rendering performance. Please find the below EGL logs details for Imagination GPU as below: OpenGL ES profile vendor: Imagination Technologies OpenGL ES profile renderer: PowerVR Rogue GE8300 OpenGL ES profile version: OpenGL ES 3.2 OpenGL ES profile shading language version: OpenGL ES GLSL ES 3.20 OpenGL ES profile extensions: After several attempts and experiments running GPU computing tests, such as OpenCL tests on the Imagination GPU, an issue arises when attempting to execute 3D programs[opengles], as they are being executed on the CPU instead of the imagination GPU.
