It should then create the log file either in ~/.local/shared/xorg.log or<br>
~/xorg.log or /var/log/xorg.log.<br>
<br>
If it doesn't, I'm somewhat surprised…<br></blockquote><div> </div><div><br></div><div>So am I. Frustrating. It must find something about the parameters passed objectionable and therefore fails to even start the Xorg instance, let alone log its output. I'd love to see stderr from the command, but I don't know how to do that. I think I'd have to replace param=Xorg with a wrapper script that did the logging ...
