Intel 82845G/GL (i810 driver) problem w/ 19" LCD

[DataTracer]

I have a Compaq Presario S5020NX, which uses an Intel 82845G/GL onboard graphics processor. I have a cheapo NIKO-1906R 19" LCD monitor that I'm using with it and I can't get the desktop/screen to sit perfectly in the center.

I've used various Linux distros with the same setup without major problems, but I've been fooling around with PC-BSD for hours trying to get X11 to work correctly!

The system boots, and the intro splash screen is shifted about 1/2 inch to the left. Then when KDM comes up, same thing, about 1/2 inch to the left. I'm using 1280x1024 (optimal for my LCD) but when I switch to 1024x768 (which looks like crap) the screen is perfectly centered! The AutoAdjust button on my monitor also has no effect and keeps the screen shifted to the left.

I've tried numerous xorg.conf and XF86Config variations. I switched from the i810 driver to VESA and X wouldn't come up at all. I copied my monitor settings and modelines from another machine I use with the same monitor, but it's still off-center. I've run X -configure, and tested many times with Xorg -config '/root/xorg.conf.new'. I've deleted the XF86Config file and rebooted, but it comes back with a generic monitor line. After updating with what I think the monitor line should be and restarting X, it's still off-center. *sigh*

I've been a linux user since '95. I'm not a newbie but I'm also no expert when it comes to graphics drivers. Am I missing something here??? This is my first time trying BSD and it's driving me nuts! It looks like a nice system if I could just get the darn screen centered, lol.

Here's my current /etc/X11/xorg.conf

Why don't you just use the monitor controls to center it?

[antik]

Change your VertRefresh 58-76 to something like 75.

[jdarnold]

Or maybe just try commenting out both VertRefresh and HorizSync, as most modern monitors will work fine without them. Although, I have to admit, for some reason X insisted on setting the VertRefresh to 59.9 on my el cheapo LCD monitor, even though it would only start at 60. I had to put in 61 for a start refresh to get it to work.

... is the one that eludes you the most! I had been relying on the "AutoAdjust" of my LCD to line up the screen and thought, "Surely it should work", and when it didn't, I figured there was something wrong with the Xorg config. I took the suggestion of Gelex and adjusted the horizontal manually, and that worked!!! I feel like an idiot now, lol :-)

I have two computers connected through a KVM switch, and it retains the correct setting when I switch to my other computer as well. Thanks for the suggestions guys!!

Problem solved.

Next problem I have to solve is the console constantly spitting out read errors regarding my built in multi-card reader! Different help area though ;-)
