Hi I have recently put together a new machine using an RX 5700 XT graphics card & X570 motherboard. I have been using it for about a month. My understanding is that kernel 5.3 provides "fuller" support for RX 5700 graphics With the 5.2 kernel (eg 5.2.18-200.fc30.x86_64) it has been working fine. Only one resolution appeared available but it seemed to work OK xrandr shows Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080 default connected 1920x1080+0+0 0mm x 0mm 1920x1080 77.00* Today's update to 5.3 (5.3.5-200.fc30.x86_64) causes Xorg to crash when evolution is used. Xorg restarts and returns the user to the login screen. Other applications seem to work OK google-chrome, google-earth, brave-browser, pcmanfm, xrandr now shows loads of different resolutions (but not that given above) Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384 DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) DP-3 disconnected (normal left inverted right x axis y axis) HDMI-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.00*+ 59.96 60.00 50.00 59.94 59.93 ... Further tests show that Logging in as "fred" and "su - ted" & running evolution as ted avoids the crash. Logging in as "fred" and "su - fred" & running evolution as fred crashes Xorg Any thoughts/advice?
