So I switched my desktop environment from Unity to GNOME3 in Ubuntu 16.04. I tried using both display managers (lightdm default in Unity, gdm3 as gnome recommendation). However my display seems to be broken. I am attaching a screenshot for clarificationI can't use any of those options

  • Your question says you're using 16.04, but you used 14.04 as tag! why?

  • @Anwar Because 16.04 tag didn't show up and I don't have enough rep to create a tag :) May 11, 2017 at 6:39
  • Then it was better not to use confusing tag. There must be a browser problem because 16.04 is a created and much used tag see here. Anyway, I edited it

The problem is associated with gtk-theme you're using, not with display manager. That theme is incompatible. I suggest using other theme.

To switch to default Adwaita theme, which should work always in GNOME, use this command

gsettings set org.gnome.desktop.interface gtk-theme 'Adwaita'

    @SudipBhandari Glad it helped. Also note that you can use other compatible theme beside Adwaita. Just change the name or use gnome-tweak-tool etc

  • Anwar Since chat requires at least 20 rep which I don't have as of now... I am posting a link to my other problem askubuntu.com/questions/912962/… May 11, 2017 at 7:10

    @SudipBhandari I checked that question. Unfortunately I'm not experienced with that question
