X11 fails on HP Pavilion dv7

I did a clean install, replacing 11.3 with 11.4 (BTW, why couldn’t 11.4 recognize a ext4 partition??).
When I boot, the cursor is a garbage block in the center of the screen. When I move, the cursor disappears. The display never progresses past the splash and no progress bar appears.
When I boot in safemode, it works, but the display is slow and jerky.
This is such a show stopper for me that I had to revert to 11.3 which does not like my touchpad.

There is no reason a ext4 partition should not work unless it is corrupted.

Since safemode works this sounds like a video card/chip problem what is your video?

Thanks for your reply.
