Hi,

I've got an hp 15-rb020ur laptop, Manjaro KDE official installation.

$ lspci | grep VGA
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Stoney [Radeon R2/R3/R4/R5 Graphics] (rev d4)

Ironically, there is no problem with KWin. It works just fine. I've been trying to configure tiling WMs, Awesome and i3. They also work, but with a lethal annoyance: they can't survive the screen turnoff on timeout, or just switching to a virtual console and back. When the DE comes back, only mouse cursor moves. Neither keys nor tapping nor buttons work any more.

My actions: Ctrl+Alt+F3; Ctrl+Alt+F1

Results:

1. KDE+KWin: Ok
2. Awesome: just the mouse cursor moving. Neither the keys, nor the mouse buttons function any more.
3. i3: the same as (2)
4. KDE+i3: the same as (2)

Awesome, i3, and KDE+i3 are usable until the switching to a virtual console.

I've done whatever research I can; found next to nothing. I'm kinda desperate. Since Awesome and i3 have nothing in common (except for the X), I have to make some xorg/video card fine tuning. Unfortunately, I've no idea where to start. I tried just this (/etc/X11/xorg.conf.d/20-radeon.conf):

Section "Device"
Identifier "Radeon"
Driver "radeon"
EndSection

It was enough to kill X server thorougly . I'd have suspected video driver, if it had not been for the KWin use case. Is there a way to analyse the settings and tell why KWin fares better than the others? It looks like I know everything about my chipset via Radeon Profile, yet I can't make much of it.

Any hint would be welcome. Where to look, what community to ask.
