Gosh, had made a concise resume of what was happening after the upgrade and hiting the preview button asked me to relogin!!!
this time i'll be brief.
So good news first, my wifi card (BCM4322) now reports signal strenght correctly (it wasn't working on UP3 neither on nm-applet nor iwlist) and seems more stable.
Function keys for volume (up,down,mute) now work!
survived the upgrade without a hitch but i've installed it from their site not the repos so guess it adds it's own repo. Haven't confirmed the later.
Response times are normal on the interface altough i don't like all that animations
Now the glitches...
-Tap is still disabled on GDM, wouldn't it be expected to have it enabled by default? Thanks @Ronis_BR for the tip on how to re-enable.
-When clicking the install button to some package on mintinstall the button vanishes doing nothing.
-Missed the 3 buttons on the windows so re-enabled them with gnome-tweak-tool, took effect after reboot but some windows still miss the close button ie. the window that pops from pidgin's new mail yellow bar, if this is normal forget it.
-Some icon themes are incomplete. ie the special icons for desktop, documents, images and such.
-Switching windows themes on gnome-tweak-tool does nothing.
-GS picked an old wallpaper as the background for when it locks the screen, where do i change that?
-Why such big fonts? I've solved this by switching back font sizes from 11 to 10 and text scaling from 1,0 to 0,8 made it more pleasant but ended up with some ugly spacing on nautilus and terminal tabs. Not an issue, more a dislike, can this be trimmed to go with the fonts or something?
-Appearance dialog won't work, should it still be in the menu? launching results in...
-Gnome-tweak-tools could benefit from a wider window as text leaps under some buttons
- Pink selection if using Mint or Mint-x GTK+ themes
-Pidgin icon missing the right size?
-Selected area is a white square...
One last thing, during the install proccess i accidentally keeped the /etc/gnome/defaults.list
file when prompted. Reinstalled gnome-session-common as it was the package installing at that moment but no offer to update the file happend. Could this cause damage in the future or am i fine keeping the old one?
