Thanks to your other post, I finally got this: ,---- | [fvwm][__explain_placement]: placed new window 0x1400010 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (normal placement) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x1400032 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (ignored program specified position) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x1400027 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (ignored program specified position) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x140003d 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (ignored program specified position) | placement method: MinOverlapPercent `---- Oh, ok, there is actually four windows, not three. I forgot about the fourth one because I didn't get to see it. A fourth window must somehow have been created after Firefox said it had crashed a Tab and I was missing a window after that. Let's try this with three windows ... The result is the same, all on top of each other at top left: ,---- | [fvwm][__explain_placement]: placed new window 0x1000010 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (normal placement) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x1000027 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (ignored program specified position) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x1000032 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (ignored program specified position) | placement method: MinOverlapPercent `---- This looks to me as if fvwm does not apply MinOverlapPercent after it ignores the program specified position. Let's see what happens when there is a window already on the page when I start Firestorm: ,---- | [fvwm][__explain_placement]: placed new window 0x800e25 'Terminal': | initial size 1146x746 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (normal placement) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x1000010 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (normal placement) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x100001e 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (ignored program specified position) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x100002d 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (ignored program specified position) | placement method: MinOverlapPercent `---- The windows are all placed on top of each other. Am I doing something wrong? Let's try that with with no Firefox and some xfce-terminal windows: ,---- | [fvwm][__explain_placement]: placed new window 0x801059 'Terminal': | initial size 1146x746 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (normal placement) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x80108d 'Terminal': | initial size 1146x746 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 1146 0, placed by fvwm (normal placement) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x8010cd 'Terminal': | initial size 1146x746 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 2292 0, placed by fvwm (normal placement) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x8010e1 'Terminal': | initial size 1146x746 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 746, placed by fvwm (normal placement) | placement method: MinOverlapPercent `---- This works as expected, the windows do not overlap. Firestorm makes fvwm ignore everything? Let's see what happens when the Firestorm windows are there and I open a terminal: ,---- | [fvwm][__explain_placement]: placed new window 0xe00010 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (normal placement) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0xe00027 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (ignored program specified position) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0xe00032 'Mozilla Firefox': | initial size 1280x2161 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 0 0, placed by fvwm (ignored program specified position) | placement method: MinOverlapPercent | | [fvwm][__explain_placement]: placed new window 0x8013e3 'Terminal': | initial size 1146x746 | desk 0 (current desk) | current page | screen: current screen: 0 0 3840x2160 (current screen) | position 1280 0, placed by fvwm (normal placement) | placement method: MinOverlapPercent `---- The Firefox windows are all on top of each other and the terminal is placed right of them, as can be expected. Any ideas? BTW, I'm seeing ,---- | [fvwm][style_parse_and_set_window_style]: <<ERROR>> Bad style option: gnomeignorehints `---- in the log file. Why is this a bad option?
