Hi! There is no file containing "core" in its name at $HOME. I searched the whole hard disk of one computer and found nothing that could be dumped by fvwm. I try another way. Here is a temporary link (would be too large for an attachment): http://www.jumping-blue-turtle.com/fvwm/config_plus_screenshots.tar.bz2 I reduced my fvwm configuration to a minimum. I ask you to try this out. I made two versions. Version 1 is: config_plus_screenshots/fvwm_2-5-26_lenny - It contains a screenshot "FvwmPager_lenny.png" to show you what I want to achieve. - It contains the pager configuration and some very simple key bindings: - Win+Arrows to scroll throw the pages - Shift+Win+Arrows to scroll throw the desks Version 2 is: config_plus_screenshots/fvwm_2_5_31_squeeze - It contains the screenshot "FvwmPager_squeeze.png". - It contains an adjusted pager and key bindings configuration Please study these configuration files and try them out. Look at the screen shots: - At the bottom left, you see a pager that shows 12 desks. - Next to this pager, in the right direction, you see a pager that shows 12 pages per desk and 4 desks at once. It shows either Desk 1 to Desk 4, Desk 5 to Desk 8 or Desk 9 to Desk 12. The small pager at the bottom left is of particular interest. This is the one that crashes (or disappears). I will explain later the precise preconditions to make it crash. It is important to understand my demands: 1.) My goal is to get a pager that does not show any part of the viewport. 2.) My goal is to get a pager that does show the complete number of the desks. Not only the half of the digit "1" but also the whole digit "1". Not only the half of the digit "2" but also the whole digit "2". And so on up to 12. The problem is that these two demands are the cause of the crashing. If some parts of the viewports are shown, then nothing crashes. If some parts of the desktop labels are not shown (if the desktop labels are not completely shown), then nothing crashes. It only crashes if the geometry of the pager exactly fulfills my two demands explained above. The next problem is that different Linux versions come with different font sizes. If the font sizes of the desktop labels do not fit to my geometry specification in the configuration files, then the pager does not exactly fulfill my two demands explained above anymore, and consequently the bug cannot be reproduced. This is the cause I made to versions of the config files with two accordant screenshots. Lenny - fvwm 2.5.26 ------------------- Look at this: > > *minipager: Geometry 110x44+2+978 Squeeze - fvwm 2.5.31 --------------------- Look at this: > > *minipager: Geometry 110x45+2+962 Since at Debian Squeeze the fonts need more space, the digits are not completely displayed with the 110x44 sizing, so I had to go up to 110x45 to get the digits completely displayed. You have to keep in mind that it is very important to meet my two demands explained above. So please, set your own geometry until you get this result. Finally, I show you how to crash the pager. Look at the file "0003_simple_keyboard_bindings". You will find a key binding "Shift+Win+Right" to go to the next desktop. So, now press the Shift key and hold it down. Do not release it. Then, press the Win key and and hold it down. Do not release it. Finally, press right arrow key and and hold it down. Do not release it. Now, fvwm is switching from dektop 1 to 2, from 2 to 3, ..., from 11 to 12, from 12 to 1, and so on. After 4 or 5 seconds (now I stopped it with the stop watch), the left bottom pager just disappears. I don't know why, but this is not normal. Please do me the favor and try this out. After you have seen it, how it disappears, you can try to answer me why this pager without further ado just - disappears. Michael
