Hi, [Please retain the CC to [EMAIL PROTECTED] so that the Debian BTS has a record of your input]
This was reported by a Debian user. Fvwm2 seems to have some trouble with the EWMH fullscreen mode. My configuration includes a stay-on-top FvwmPager. When putting EWMH compliant applications, such as tvtime, the pager is not obscured by the fullscreen window, so I get a TV window with a pager floating on top, which is less than desirable. The bug can also be reproduced with the fullscreen modes in Mozilla Firefox and OpenOffice.org, but I have not tested using this extensively as I have with tvtime. The bug can be worked around by setting: Style * EWMHUseStackingOrderHints in the .fvwm2rc file. After investigating the problem, my analysis of the problem is that it seems (according to the excellent fvwm manual page) that the EWMHUseStackingOrderHints was intended to disable/enable some KDE-specific extentions. Unfortunately, the slightly misleading option name lead a programmer to misinterpret the meaning of the flag when programming the fullscreen code, and made that disable the stacking code in that when it was enabled. The fact that the option is not intended to disable *all* stacking hints is further supported by the fact that tvtime also has an (AFAIK) EWMH-compliant Always-on-top mode, which does manage to obscure the pager properly, even when EWMHUseStackingOrderHints unset. From http://www.freedesktop.org/standards/wm-spec/1.3/ar01s07.html#STACKINGORDER # Stacking order # # To obtain good interoperability between different Desktop Environments, # the following layered stacking order is recommended, from the bottom: # # * windows of type _NET_WM_TYPE_DESKTOP # * windows having state _NET_WM_STATE_BELOW # * windows not belonging in any other layer # * windows of type _NET_WM_TYPE_DOCK (unless they have state # _NET_WM_TYPE_BELOW) and windows having state _NET_WM_STATE_ABOVE # * focused windows having state _NET_WM_STATE_FULLSCREEN # # Windows that are transient for another window should be kept above this # window. # # The window manager may choose to put some windows in different stacking # positions, for example to allow the user to bring currently a active # window to the top and return it back when the window looses focus. Let me summarize: If the EWMHUseStackingOrderHints style is on, fullscreen works. Pager is hidden as it should be. If the EWMHUseStackingOrderHints style is off, fullscren works, but pager is not hidden. But, EWMH always-on-top modes such as the one found in tvtime still works. According to the documentation, EWMHUseStackingOrderHints affects KDE-specific extentions. The extentions mentioned aren't KDE extentions, they are a part of the EWMH standard 1.3 from freedesktop.org. So either the documentation is wrong or the code is wrong. And still, you shouldn't have to activate a special option in order for FVWM to fully comply with the recommendation in the standard. So, I see two possibilities: - The option is intended to tell EWMH never to dictate stacking. In that case it's broken since tvtime's EWMH always-on-top stacking still works when that option is disabled, and the documentation is wrong. - And what I think is more likely: The option was intended to activate special KDE-specific extentions (as per the documentation) but somehow breaks fullscreen mode to be out of compliance with recommendations if disabled. This has nothing to do with KDE extentions AFAIK. The bug has been tested mainly on fvwm debian versions 2.5.10-12 and 2.5.10-13 (latest testing versions), and has also been tested against 2.5.12 from the tarball from upstream. manoj -- An economist is a man who would marry Farrah Fawcett for her money.
