Re: did the weston can use "mesa" for "opengles and egl" demands without libmali.so on MALI targets?

Printing to the terminal stops working once Weston enters graphics mode. If you are launching weston through a serial console, maybe it overflows and drops random bytes - is your serial flow control correctly set up also for the kernel console output? It looks like you get kernel bug output too. A kernel bug is always a kernel issue, so you would need to look into that first. Also make sure that Weston is not somehow patched for Mali specifically. I don't know if such patches exist, but if they do, we can't support them.

Re:Re: did the weston can use "mesa" for "opengles and egl" demands without libmali.so on MALI targets?
is that mean that the libmali.so could be replaced by mesa implementation totally? if so, the accelerator function could not be used, is that true? i would make experiment as you said, thanks for our good advice.

Launch Weston at tty1
I can able to launch Weston at tty7 but not able to launch at tty1. Why?? ___ wayland-devel mailing list wayland-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-devel
