[SLUG] Slight flickering on dual monitor set up

elliott-brennan Sun, 08 Apr 2007 22:55:11 -0700

Hi all,

I'm wondering if anyone has any suggestions or advice?

I'm running Kubuntu 6.06 on a Hyperthreaded 3GhzP4 with 1.5G RAM.

I have to 17" Philips monitors (107T5 - primary -and a 107S6 - secondary) running off a 128MbNvidia FX5500 dual-head card.

At times (e.g.. when I open mail from Thunderbird)I get a slight flicker on the second monitor andsimilar on the primary monitor.

I've tried various refresh frequencies, but to noavail.

I've posted (below) my xorg.conf in case anyonehas any suggestions or can see something that Ican't (highly likely :)).

NB. I modified xorg.conf to show only 1024x768 asdual-display it wouldn't play nice otherwise.


Thanks for any assistance or advice offered.


Regards,

Patrick
