I have Ubuntu 18.04 installed on my HP laptop. This morning after restart it wasn't able to find my second monitor, which is connected via HDMI. I had those issues before, and fixed them by restarting multiple times, connecting HDMI to my TV etc, but this time it did not work.
I have found the answer on stackoverflow to switch to lightdm as a solution to my problem. I installed lightdm with apt-get, ran sudo dpkg-reconfigure lightdm and restarted the computer.
New appearence was there, other monitor on HDMI was also there. I encountered next problems :
- My battery indicator was not showing how much I have left (stuck at 48%) and wasnt showing when I plug charger that it is charging
- Title buttons were on the left side of windows, which is not what I am accustomed to since I also have other computer running Windows.
So I started googling to fixing that, I have Tweaks installed, but when selecting right/left position it only affected the Tweaks window, others were still with buttons on left side. I have tried (found it on stackoverflow also)
gsettings set org.gnome.desktop.wm.preferences button-layout ':minimize,maximize,close'
which didnt have the effect, also found on some answer
gsettings set org.gnome.settings-daemon.plugins.xsettings overrides "{'Gtk/DecorationLayout':<':minimize,maximize,close'>}"
but that also didnt work, the title buttons were still on the left side.
After that I completely removed lightdm, purged, restarted, gdm3 login screen appeared but the desctop appearence was the same as when using lightdm, still battery icon issue and still buttons on the left side. I have tried than installing lightdm and removing/purging gdm3 but the issue remained the same.
Help would be appreciated, since I cannot just accept buttons on the left side and ignore battery icon, and reinstalling OS would be super painful since I have tons of stuff set (I use laptop for sotware development)
