Just powered up my new X15 for the first time - no issues getting serial console working, but I'm getting distorted garbage out of the HDMI port and see dmesg errors:
Error creating gpu
libGL error: failed to create dri screen
libGL error: failed to load driver: etnaviv
Wondering if anyone has seen this, if I have a bad board, or something else. The display is an ultra-wide FTR, so perhaps there's a resolution issue? The HDMI cable and display are confirmed to be working.
