For now, this seems to work for me, thanks! |
Created attachment 290103 [details] Kernel log when error occurs I have a RX 5700 XT NAVI10 with (well almost) no problems but since kernel 5.7.6 came out there is a serious problem which makes the card practically unusable. Kernel 5.7.7 brought no relief. With kernels <=5.7.5 all is OK. The problem only occurs if I have both of my displays connected. One is a monitor via DP, the other is a TV via HDMI. When I disable the TV so that I only have my monitor active its screen shows some weird freezing behaviour and sometimes goes completely grey for some seconds, then black and afterwards is not really useable any more. If both displays stay active or only the TV is active or I do not connect the TV in the first place there is no problem. I have attached the kernel log for when the error triggers. Some other info that may be of importance: - kernel: gentoo-sources - xfce4-4.14 - xorg-server-1.20.8
