View Full Version : [ubuntu] Problem with flickering on inspiron 1720 with Ultrasharp monitor

September 3rd, 2008, 06:04 PM
Hey guys, I have problem because I use Ubuntu 8.04 on my Inspiron 1702 with Ultrasharp 17 widescreen LCD wich comes with natural resolution 1920x1200. Now, I had Vista on it an it was beautifully smooth but on Ubuntu, even when I have managed to change the refreshing rate to 60MHz, the same as in Windows, I cant get rid of this strange horizontal lines that looks like problem with refreshing rate. Its visible the most in firefox while browsing or on some video web pages like vimeo when if I make it fullscreen for the video it slows down completely and the refreshing is terrible together with the sound. Even though there is the most obvious everywhere u can see it: on games, on 3d software. Please does any on know whats wrong??

This is the output from my xorg.conf:
