dmesg output with drm.debug=14
Attached is output from "dmesg" and "lshw".
-- system architecture: 64-bit
-- kernel: 4.9.0-994
-- Linux distribution: Ubuntu Gnome 16.04
-- Machine or mobo model: Tesco Windows Connect
-- Display connector: ???
I'm using a 10.1-inch Cherry Trail tablet. The kernel is drm-intel-nightly
branch (drm.debug=14) and is 64-bit booting from a 32-bit uefi with grub2
(dunno if that's relevant or not).
When I boot, text scrolls down the screen and after a few seconds the text gets
wiped off leaving a black screen. This issue does not correct itself, but I
can type commands into a tty without remote access (just can't see the commands
I type in).
I'm not sure if this is the right channel to report this, and I appreciate
there are other details I may need to provide.
Thanks.
p.s
As noted in similar bug reports, there are other problems with the device as
well. I don't have any audio (not sure if that's because I've not got the right
driver), and there's problems with hardware buttons and sleep mode.</pre>
