Bug ID: 205069
Summary: Black screen when starting graphical environment
Product: Drivers
Version: 2.5
Kernel Version: 5.3.1, 5.4.0-rc1, latest
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org

kernel .config 5.4.0-rc1
Hello there
On kernels 5.3.1 and 5.4.0-rc1, I get a black screen with a white underscore
cursor in the upper left. The display gets stuck in this state, with no way to
switch to a different TTY or leave this aside from hitting the reset button.
I can secure-shell into the box and get a login at this time, but killing the
process does not fix the display. Sway WM also does this, with it just getting
stuck at the prompt entry.
I have an AMD RX 5700 graphics card, using the amdgpu driver. When I do some
manual configuration by blacklisting amdgpu and writing a stanza in xorg conf
for vesa, I am able to get X running using vesa.
uname -a output: Linux gentoo 5.4.0-rc1 #1 SMP Tue Oct 1 14:24:57 EDT 2019
x86_64 AMD Ryzen 5 3600 6-Core Processor AuthenticAMD GNU/Linux

I've seen another report on a similar issue, where the suggestion (solution?)
was to be using a newer mesa and llvm. I am on llvm 9 and mesa 19.2.0
* media-libs/mesa
Latest version available: 19.2.0
Latest version installed: 19.2.0_rc4
* sys-devel/llvm
Latest version available: 9.0.0
Latest version installed: 9.0.0

Was Mesa built against LLVM 9, not an older version?
It looks like the problem occurs when the Xorg driver tries loading glamor, so
a Mesa/LLVM issue is most likely.

Gotcha. I did not know until very recently that the graphics output for this
kernel navi driver required a specific set of userland libraries to exist. I
recompiled mesa and also got onto a new version of llvm-common for good
measure.
This worked! Thank you for your help! I am able to launch Xorg on AMDGPU
driver, without resorting to vesa, and can also run Sway wm. No display
freezing or anything like that. I'll set this as resolved.
Reminder for future reference if someone comes across this with the same issue.
You need at minimum LLVM 9 and Mesa 19.2.0. The LLVM has to be installed first.
Thank you again.
