I have an STM32MP151 (none GPU) processor and I’m running Ubuntu 24.04 LTS. When I start up the weston window manager, everything seems to work. But there are two problems:
- No mouse cursor
- The HDMI quit the connection to the TV screen after few minutes
First, I have no USB mouse connected. Second, the HDMI losing its connection when unexpectedly large timestamp jump appears.
Why questions are simple: Why does my HDMI lose its connection and why can’t I see any mouse pointer at the screen?
