Smooth Fonts For Opera In Linux

I have been using Opera as a standards-compliant, efficient and cross-browser. In fact it is one of the browsers that uses Qt toolkit, and hence has better performance on KDE, though it never has been my default browser. One big reason is that some fonts are rendered terribly on Linux. I am currently using Opera 9.23 on Kubuntu.

Anti-aliasing is already supported, but fonts like Helvetica and Courier New are rendered broken and extremely thin. Which means that sites like twitter are not rendered readable. This Ubuntu thread helped me find a partial solution to this problem. The solution is to disable the core X fonts. In ~/.opera/opera6.ini (I do not know why it is called opera6) add Enable Core X Fonts=0 under the section [User Prefs]. If you want to do this for all users, you can add it to /etc/opera6rc as the root user.

The reason I am calling this a partial solution is because this actually disables the X fonts. Which means that Opera displays other fonts instead of displaying Helvetica. But it is still a solution because it makes it usable, and this will definitely drive me to use it more.
