Whenever I try to start Clementine player, I get kicked to the lock screen and need to log in again. I tried reinstalling the graphics driver which allowed me to use Clementine again, but not a second monitor. So after I fixed the settings for dual monitor, I have the old problem again and I get logged off from my session once I try to start Clementine.
I have an nvidia graphics card and I have configured in xserver a twinview to use both my notebook's screen (Lenovo ThinkPad T410) and and external Acer monitor connected via vga at the same time. Graphics card is Nvidia NVS 3100m
