Dell 2407WFP under KDE?

mr_angry

Hey guys,

I was installing SuSE-10.2-x64 on my home desktop recently, and was expecting plenty of problems, given the hardware setup I have there (ATi card, 802.11n wireless, etc). Nevertheless, I was pleasantly surprised to find that there were no such problems, and after some minor patching here & there, things went rather smoothly.

Anyway, I'm left with just one problem, and that is getting my 24" dell monitor to run at 1920x1200 under KDE. Having trawled the list of hardware drivers, the 2407WFP was notably absent. Initially, I tried running it as a generic LCD, but the monitor itself was complaining that the proposed settings were out-of-range. After more messing around, I managed to manually set the horizontal and vertical refresh rates, and everything seemed hunky-dory. However, in the KDE desktop manager, the maximum desktop space it will allow me to use is 1600x1200, despite SaX claiming that the monitor is running in 1920x1200. The result is a rather stretched-looking desktop, which is annoying.

I've trawled numerous internet fora looking for a solution, but nobody even seems to be suffering the same problem. Any suggestions?

It's pretty strange that it's just happening with KDE. Could you post your xorg.conf?

This guy solved it with a custom xorg.conf modeline. Seems to be a fairly common problem.

Thanks for the tip Snowbat, but it didn't seem to solve the problem for me. I reckon its definitely something to do with xrandr, as I'm told that KDesktop display configuration gets its information from there. SaX seems to have the correct data, but its the KDE widget itself that is causing the problem.

Here is my xorg.conf anyway:

As you can see, I've attempted to edit the conf to reflect the advice from the thread you've linked to, but with no success. The widget that seems to be causing the problem is demonstrated in the image below. Having attempted to setup a dual-head configuration, it now defaults to 3200x1200, despite the fact that I've removed the second screen, and any reference to it from my xorg.conf - I don't think I can express just how annoying this is! Worst of all, it still doesn't list 1920x1200 as an option.

I've searched for people reporting problems with this widget, but can't seem to find any mention.

Set the monitor to display at a 1:1 pixel ratio. Will display 1600x1200 at the correct ratio while leaving borders down each side. Also very handy for running games in windows that do not support widescreen resolutions.

Can't be ****ed reading the post in detail (head is wrecked) but this line stood out:

ModelName "1920X1200@75HZ"

Tis the wrong refresh value for an LCD. Most are 50hz I think with recent ones being 60 I think. No idea if this is causing the issue but might explain why the monitor is displaying the "out of range" error.

Khannie

Just for clarity: There's nothing wrong with that modelname, but the modeline you have (if at 75Hz) will cause the out of range error.

"xorg.conf: Linux's greatest ongoing failure." (IMO)

Yeah, thats just the model name, as selected from the list of generic LCDs. I manually set the horizontal sync and vertical refresh rates, as illustrated in the mini-xorg segment in my previous post. I got it straight from the 2407WFP technical specifications, and I'm certainly not getting any further out-of-range errors, so I'm satisfied that particular element isn't causing a problem.

I added a line to "Section 'Screen'" stating:
Virtual 1920 1200

This has made an interesting alteration. xrandr now offers me a resolution of 3300x1200, which happens to be 1920+1280x1200. I figure that its still including the phantom second screen, but it has at least proved that modifications to xorg.conf will affect xrandr. Now all I have to do is figure out where the hell its getting the information for the phantom screen!

I've heard on other fora that SuSE-10.2 installations provided native support for the 2407WFP, which surprises me, as it isn't in the list of supported hardware in SaX on my own installation. Does anyone know the name of the pack that includes hardware support for monitors? If I knew the name, I'd happily attempt to update it through YaST.
