In almost every application (the file browser, the system profiler, even firefox start page) icons don't display properly. Some of them are white squares, and appear if I move my cursor, some of them disappear when I move them. I had this problem with prior versions of Lubuntu as well.

In system information it says:

Vendor : unknown
Renderer : unknown
Version : unknown
Direct rendering : unknown

Is this the cause of the problem?

    Could you please add a screenshot (you can use imgur.com or similar if you don't have enough rep), and have you tried changing the icon theme (look for 'Customize look and feel') – Wilf Nov 19 '14 at 20:02
  • i changed my icon theme but the problem was not solved – manolismi Nov 20 '14 at 18:09
  • What do you mean about "system profile html file"? If they are NOT private information for you, you can post them on paste.ubuntu.com and reply the link. – αғsнιη Nov 20 '14 at 18:34
  • System profiler generates an html file with my hardware info, and I don't know a way to upload it. Also, i found a legacy driver package that supports my graphics card from nvidia. It requires installation without 'X'. How do i close 'X'? – manolismi Nov 20 '14 at 18:55
  • Should i install this driver first? – manolismi Nov 20 '14 at 19:15

I solved the problem by disabling edge smoothing in the Appearance options, using LXAppearance 0.5.5 (Start → Preferences → Appearance). Simple, but it works.


Problem solved. Go to Start → Preferences → Appearance → Font and uncheck Disable antialiasing.
