Outstanding ... Thanks to all concerned. Like how a text message pops up whilst on the Plymouth splash screen to say that fsck is running (clearer indication of why the longer boot time rather than in Jessie when I had to <esc> to see that fsck was running).
Upgraded from Jessie, jwm/pcmanfm core gui setup. Previously was using a Raleigh type consistent theme across gtk2, gtk3, qt ... but I've switched over to using a common Adwaita theme across gtk2, gtk3, qt4, qt5 (along with tweaking jwm to also have a adwaita theme look-n-feel).
Initially some warnings in ~/.xsession-errors about deprecated ...., tweaked ~/.config/gtk-3.0/gtk.css as indicated by those warnings.
/usr/share/applications/mtpaint.desktop Exec line was using a %U parameter and not opening files. Changed that to a %f parameter and works fine now.
Outstanding ...
1. RadioTray warnings in ~/.xsession-errors
Code: Select all
/usr/lib/python2.7/dist-packages/radiotray/XmlDataProvider.py:23: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
from gi.repository import Gtk
/usr/lib/python2.7/dist-packages/radiotray/AudioPlayerGStreamer.py:64: FutureWarning: The behavior of this method will change in future versions. Use specific 'len(elem)' or 'elem is not None' test instead.
if(cfg_provider._settingExists("buffer_size")):
/usr/share/radiotray/plugins/NotificationPlugin.py:25: PyGIWarning: Notify was imported without specifying a version first. Use gi.require_version('Notify', '0.7') before import to ensure that the right version gets loaded.
from gi.repository import Notify
Also a issue with LibreOffice Tools/Option/View Scaling dialog size
Other than that the upgrade went really smooth/easy, and is now looking really good. Again thanks to all concerned.
