Comment 30 for bug 1509997

Christopher:

1) I used to have radeon.dpm=1 to save power (although, I don't have numbers how much better it is with respect to no parameter).

2) I can't.
My Ubuntu 17.10 (and according to my knowledge it's a trend in the community) runs with Wayland, not Xorg so there is not Xorg server with its log file. Thus, as suggested on the webpage (https://fedoraproject.org/wiki/How_to_debug_Wayland_problems), I use journalctl to combine all relevant log information. Thus, you do have entire logs, only with different file names.
