A few Lubuntu Menu things...

[Eric Bradshaw]

I hope the details below helps someone figure some things out about no 
icons, blank icons and icons that are too big. And as mentioned 
previously by Aere; there is quite a bit of variation in the way 
developers tackle the icon "problem." I looked a little deeper and tried 
some experimenting with apps installed through LSC starting with the 
letter "E."

For the application called eFTE, which shows no icon (default icon in 
menu, blank on the desktop); there are 4 icons in usr/share/pixmaps
efte16x16.xpm
efte32x32.xpm
efte48x48.xpm
efte64x64.xpm
This is referenced in the shortcut as Icon=efte

I copied the shortcut to the desktop and changed just the Icon= line to 
reference the path to the 32x32 icon
Icon=usr/share/pixmaps/efte32x32.xpm
This had absolutely no effect. I tried each of the other sizes as well; 
16x16, 48x48 and 64x64. None had any effect - still a blank icon.
I also tried moving the Icon= line to the top of the shortcut, just 
below [Desktop Entry]; nothing.
I then moved the Icon= line above [Desktop Entry] and this time after 
saving, the default icon was shown.
Next, I deleted all but the 64x64px icon in usr/share/pixmaps and 
renamed it simply efte.xpm. I then moved the Icon= line back down below 
the Exec= line, but left the path. The icon went back to being blank. 
Finally, I removed the path, so it was now Icon=efte.xpm (only the 
64x64px icon still remained in usr/share/pixmaps and the icon's name is 
simply efte.xpm) and the icon showed on the desktop! I (tested to make 
sure the shortcut still worked from the desktop to open eFTE) then 
replaced the shortcut in /usr/share/applications and the icon showed in 
the menu too! The menu now showed a large icon for eFTE; 4 times the 
size it should have been. Next (because I had really deleted all but the 
64x64px version) I halved the size of the icon in GIMP and overwrote it 
in /usr/share/pixmaps. And because it was still showing the 4x size in 
the menu, I entered lxpanelctl restart in LXTerminal and the icon had 
shrunk to twice the size as normal - the 32x32px size. I halved it again 
to 16x16px and again entered lxpanelctl restart in LXTerminal and the 
icon then finally showed in the menu at a normal size.

In the case of Emila Pinball, which shows a large icon (roughly 4x 
normal size); there is only 1 icon in the same location
pinball.xpm
This icon is 32x32px, 72 dpi.
This is referenced in the shortcut as Icon=pinball.xpm

emesene, which shows a normal icon; has both an .xpm (at 32x32px) and a 
.png (at 96x96px) in usr/share/pixmaps
emesene.xpm
emesene.png
Referenced in the shortcut as Icon=emesene

ELKI, which shows a normal icon; only one icon resides in usr/share/pixmaps
elki-icon.png
It is also  32x32px, 72 dpi
In the shortcut as Icon=elki-icon

Hope some of this sheds some light.
