xf86-video-intel-2.1.1 monitor detection issues

Hi all,

I've recently had a client come across a problem with monitor detection on an Intel 945G based motherboard using xf86-video-intel-2.1.1. In particular the monitor he has had trouble with is an LG M1921TA (he also has a Samsung 19" LCD which works perfectly). I'm lead to believe that a few different 'standard VGA cables' were tried. After trying everything I could think of (and google), I delved into the driver code to find that in i830_crt.c this function:


was returning false. The comment above this function states something like "returns true if CRT is connected" "returns false if CRT is disconnected". Along with this function I also see the comment: "Only for I945G/GM".

I put in a little hack to ignore the results of the register queries in this function and return true, and then the monitor seems to work fine. Is this likely to be a problem with the monitor or cable or motherboard perhaps?

Any ideas why this would only be for I945G/GM chipsets?
