Hi, Dave
how to use the modesetting dreiver? Ubuntu has no
xserver-xorg-video-ast package,
so if startx, the modesetting module (and the fbdev module) seems
loading by default
after the AST driver failed:
[ 2483.516] (II) LoadModule: "modesetting"
[ 2483.516] (II) Loading /usr/lib/xorg/modules/drivers/modesetting_drv.so
[ 2483.516] (II) Module modesetting: vendor="X.Org Foundation"
[ 2483.516] compiled for 1.17.1, module version = 1.17.1
[ 2483.516] Module class: X.Org Video Driver
[ 2483.516] ABI class: X.Org Video Driver, version 19.0
And the modesetting module seems working correctly, But there are no
VGA output, I
can change back to console by ctrl+alt+F*, also I tried vnc server, no success.
