I have installed Cities Skylines on my HP Envy m6 laptop with Ubuntu 14 installed. I also have the laptop plugged into a 27 inch monitor.
The game appears to run without any issues, except for an exception when closing down. However, when I try to mark any of the first zones the zone colours are incredibly faint. So much so, that when I first tried to zone an area I kept clicking and dragging thinking that nothing was happening.
It took some time before I realised the zones were in fact being marked, it's just hard to see.
Is there a way to increase the visibility of the zone colours?
Perhaps a mod that does this?
