I have a 9530. Unfortunately the only way I could make it boot is to add "nomodeset".
It will be extremely slow if I use 3200x1800 resolution... However when I put vga=ask in it there's no other wide screen resolution for me to choose.
I tried the i915 driver but I failed. I tried UVESA_MODE=1920x1080 however it went into 1920*1200 automatically. It seems to be a little bit smoother if I use UVESA_MODE= instead of vga= but I'm not quiet sure of that.
Interestingly, it will only boot through GRUB(which is the legacy boot). If I try to boot from GRUB2x64(which is the UEFI boot), it shows kernel panic immediately.
That's all I have in my hand right now.
I'm so happy to see some one using the same device as mine. ;D
