thanks for the hint! The options were there, didn't think of them at
first because hidden in a sub-menu.

I have the following options: 32-64-128-AUTO
It was set to 32.
At 64, 128 or AUTO (which apparently seems to set it to 128 according to
the dmesg?) works.
How does it come that 32MB is enough for X11 but gives issues to the
console... leading to only a cursor moving?

at AUTO this is an extract of the dmesg.

I notice really a lot of errors. ringtest, cp and at the end GPU
acceleration disabled.

Thank you,
Riccardo
