I'm currently using Kubuntu 12.04 and after installing nVidia drivers and Setting resolution up to 1440x900 limit, fonts look ugly,only browser content fonts work well, I tried fixing them using Fonts-KDE contol Module, but it didn't work, Please help here is a screenshot
Open KDE Settings Manager
Then go to Application Appearence
Select Fonts section
change the Use anti-alialising option to Enabled
Then click Configure button.
In the new window, select Use subpixel-rendering and change the value to RGB
Change the hinting style to Slight.
Then remove the file
.fonts.conf
in your home folder. It is a hidden file. To see, that file in Kubuntu, PressAlt
+.
.Here is a screenshot of the settings window
Logout and Login again.
In your home folder, rename .fonts.conf to .fonts.conf.bak then log out. Log back in and the fonts in Firefox are good to go.
