| Summary | When positioning a monitor output above or below initial conf= iguration with xrandr, hard freeze with graphics artifacts 4.16.2+ |

I'm unable to position my monitors outside of an inline config= uration. I have 5 monitors, and if I try to position one outside of an inline configuration w= ith xrandr, it results in a hard lock. Steps to replicate the process: $ xrandr --fb 7680x2160 xrandr --screen 0 output shows that the virtual desktop is set to 7680x21= 60 $ xrandr --output DP-6 --pos 0x1080 At that point, mouse and keyboard become unresponsive. After about 30 secon= ds, monitor output shows artifacting. I'll see if I can post an image of what I see. It appears this also causes all network activity to stop. The system cannot= be pinged, and SSH server stops functioning. Seems to have the same issues as https://bugs.freedesktop.org/show_bug.= cgi?id=3D106159 which freezes the system when connecting or disconnecting a displayport cable.

Created attachment 139013 [details]= [review] [PATCH] drm/amd/display: Disallow enabling CRTC without primary plane with = FB Does this help?
If the patch doesn't help are you able to capture the dmesg lo= g and post it?
Hey Harry, Thanks for your help. Should I be using my current kernel, or just download the newest source to apply these patches against? Some of the other patches didn't really have the context useful to patch against, and I am not sure if these kernels will have the amdgpu.dc kernel switches. Thanks!
I recommend using drm-next-4.18-wip from Alex's tree: https://cgit.freedesktop.org/~agd5f/linux/?h=3Damd-staging-drm-next git clone git://people.freedesktop.org/~agd5f/linux cd linux git checkout drm-next-4.18-wip The patch should land on that branch in a couple days.
Harry, as I had mentioned here https://bugs.freedesktop.org/show_bug.= cgi?id=3D106159 I had to manually apply the patches you'd given me, so I'm including the diff here as well. This has both of the patches in it, so I figured I'd attach i= t to this bug as well. Thanks!
