<pre>I recently bought a WinBook TW-700 tablet for its low price and Intel/amd64
compatibility. I got Debian installed on a USB drive. The tablet uses 32-bit
EFI only, no BIOS compatibility mode. If I boot with nomodeset, the tablet is
usable with no acceleration. If I boot without nomodeset, the tablet shows the
boot messages up until drm is initialized, and then the screen goes black. I
can ssh into the tablet (via USB Ethernet) and it seems to think the display is
operational.
I have tried the latest 4.0-rc4 and intel-drm nightly kernels from Ubuntu's
kernel PPA, but both exhibit the same problems.
I will attach dmesg with drm.debug=0xe and the Xorg.0.log after I tried running
xinit from the SSH session.</pre>
