Comment # 13
on bug 106671
from Alan W. Irwin
Well, after 1.5 (successful) days with the remote graphics experiment, I decided instead it made more sense to go after the quicker acting instability that I have previously experienced in direct graphics mode. So just now I have started a direct graphics experiment after a Debian Testing upgrade which included the following firmware and mesa changes: firmware-amd-graphics updated "(20180825+dfsg-1) over (20180518-1)" mesa updated "(18.1.7-1) over (18.1.6-1)" In addition for this experiment I installed the amd64-microcode package that contains "microcode patches for all AMD AMD64 processors". Also, as part of this experiment I have continued with the idle=nomwait kernel parameter as verified by irwin@merlin> cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-4.17.0-3-amd64 root=UUID=1e45a1ee-a5d6-4327-9a7b-2663ffc0b157 ro rootwait quiet idle=nomwait N.B. note those kernel parameters do not include any amdgpu-related parameters. Do you recommend any such parameters for the RX 550 such as amdgpu.dc=1 which is sometimes recommended for older versions of AMD new-generation graphics hardware?
