52 | as it appears, you need to use this three-step process: | |
53 | * Specify X resources to give the geometry you want. | |
54 | * Set `default-frame-alist' to override these options so that they | |
55 | don't affect subsequent frames. | |
56 | * Set `initial-frame-alist' in a way that matches the X resources, | |
