I've recently installed a fresh 13.04 Ubuntu 64-bits version on my DELL Latitude laptop and the OS built-in display manager was handling fine the dual monitor mode.
As I wished to have Nvidia driver to have a better experience I followed these steps to get it: http://www.dedoimedo.com/computers/ubuntu-ringtail-nvidia.html
However, after installing NVidia proprietary drivers, my Ubuntu was failing to start properly, and after system start-up, only the desktop was appearing, with no Unity, nor Launcher nor Dash appearing.
Then I could succesfully remove NVidia drivers by doing the following steps:
- Switch to console mode: Alt Ctrl F1
sudo service lightdm stop
sudo apt-get remove --purge
sudo X -configure
sudo mv xorg.conf.new /etc/X11/xorg.conf
sudo start lightdm
After all this, system was working again, but with this annoying issue: when I try to maximize any window, it always goes maximized to the display on the right.
Also the mouse cursor vanishes on the screen if I drag it to the right edge of the right monitor, and reappears only when I move the cursor back to the left screen.
I have already extensively googled for similar issues reported by other users, and tried some solutions, but the issue still happens for me.
Didn't work for me:
- using launchpad with Ctrl SUPER arrow keys
- installing COMPIZ config settings manager
- setting external monitor as primary instead of secondary
- "dconf reset -f /org/compiz/" followed by "unity --reset-icons &disown"
Any help would be MUCH appreciated, as for now the only solution for this would be reinstalling the whole OS : '(
