Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Disable the XRandR extension by default, since KDE maximizes windows which are larger than the new resolution, and then doesn't restore their size and positition when the old resolution is restored. The extension can be enabled with the environment variable SDL_VIDEO_X11_XRANDR=1
