Hi I am trying to use radeon driver git (38797a33117222dadbc89e5f21ed8cd5deef9bea) together with 2 radeon cards under Linux 64bit. # uname -a Linux denis-devuan 4.6.0-0.bpo.1-amd64 #1 SMP Debian 4.6.4-1~bpo8+1 (2016-08-11) x86_64 GNU/Linux # lspci | grep VGA 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus LE [Radeon HD 8830M] (rev 87) 04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus LE [Radeon HD 8830M] (rev 87) It works until I try to rotate one of outputs. $ xrandr --setprovideroutputsource 1 0 $ xrandr --output DisplayPort-1-1 --auto $ xrandr --output DisplayPort-1-1 --rotate left --left-of DisplayPort-0 Right after attempt to rotate rotated output hangs. The other one still works though.
Rotation without TearFree works, but tearing of large displays (2560x1440) is scary.

Does xrandr --output DisplayPort-1-1 --auto --rotate left --left-of DisplayPort-0 as a single command work?
Yes, single line command works, but with some quirks. Rotated display seems like lacks redraw(damage? not sure how to call them) events in its bottom half. Does it has something to do with height of right display? Mouse cursor leaves trails, moving windows leaves their contents on desktop, etc. I mean my display configuration is: +----------+---------------+ | | | | 1 | 3 | | | | |----------|---------------| | | | 2 | | | +----------+ 1,2 - halves on rotated display and 3 - horizontal monitor. 1 and 3 - redraw ok, 2 - does not. Hope it'll help.
The missing redraws should be fixed with current xf86-video-ati Git master. Can you still reproduce the original problem with that?
Works perfectly now. Thanks a lot!
