Created attachment 137976 [details] coredump stopping xorg I'm currently facing two issues that I think are related: 1) When I try to suspend the computer from the desktop environment (XFCE), it immediately freezes. 2) When I stop xorg from the console (systemctl stop lxdm), xorg crashes with a coredump. The computer is still responsive, until I switch to console 7 (alt-F7), then it also freezes. Kernel and Xorg versions: X.Org X Server 1.19.6 Release Date: 2017-12-20 X Protocol Version 11, Revision 0 Build Operating System: Linux 4.14.12-1-ARCH x86_64 Current Operating System: Linux TuxServer 4.15.7-1-ARCH #1 SMP PREEMPT Wed Feb 28 19:01:57 UTC 2018 x86_64 Kernel command line: BOOT_IMAGE=/vmlinuz-linux root=/dev/mapper/SystemGroup-arch_prod rw quiet ipv6.disable=1 ipv6.disable_ipv6=1 amdgpu.dc=0 Build Date: 26 January 2018 10:25:18AM Graphics hardware: Radeon RX 550 4GB Currently I'm using the xf86-video-ati driver, _not_ amdgpu. With amdgpu, the issue also occurs. I have three computers with the same operating system, all of them up-to-date, but the issue only occurs on the computer with the Radeon RX 550. The other ones have an older AMD graphics card (Radon HD 5450) respectively intel on-chip graphics (Celeron J 3455) I've attached the core dump, and this is what I get in the system journal: Mar 09 18:40:27 TuxServer systemd[1]: Stopping LXDE Display Manager... -- Subject: Unit lxdm.service has begun shutting down -- Defined-By: systemd -- Support: https://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit lxdm.service has begun shutting down.
