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:
i830_crt_detect_hotplug
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?
Thanks,
Brad
