No X with my new LCD monitor[solved]

Shaika-Dzari · 2006-06-09 23:26:58

Hello!

I buy a LCD monitor.
This one:http://www.benq.ca/Products/LCD/index.c … ifications

I want to have a 1680x1050 @ 60 htz resolution but xorg start at 900x600.

I modify my xorg.conf and add this modelines:

shaika-dzari:$ gtf 1680 1050 60                                                                               

  # 1680x1050 @ 60.00 Hz (GTF) hsync: 65.22 kHz; pclk: 147.14 MHz

  Modeline "1680x1050_60.00"  147.14  1680 1784 1968 2256  1050 1051 1054 1087  -HSync +Vsync

But it doesn't work.

Is someone with a LCD at 1680x1050 can post is xorg.conf and help me to discover my precious Fvwm with my new LCD?

Thank you for your help.
If you need more info, tell me.

Check the log, it may (should?) say where the problem is.

Hello!

You are right! I forgot to check the log... :oops:

I saw 2 errors for the resolution 1680x1050

hsync out of range

bad mode clock/interface/doublescan

Any idea how can I solve this error?

I search on the forum and grab the xorg.conf from fubar and try something.
I was able to start X but just in 1400x1050.

Thank you for you help!

do a hwd -x to do it automatically
Try xorgconfig -textmode to do it by yourself,
Add the horizontal sync according to your own specifications

I already try hwd -x but the file has no modelines for this resolution.

I will try xorconfig -textmode and see if I can obtain a right conf file.

I know from my LCD manuel that 1680x1050 must have 75 for horizontal sync and 60 RefreshRate at 162 frequency.

This are maximum.

Must I put in the xorg.conf something like that:

Section "Monitor"
Identifier "BenQ"
HorizSync 75
VertRefresh 60
EndSection

or I must have 2 valors:

Section "Monitor"
Identifier "BenQ"
HorizSync 30 - 75
VertRefresh 30 - 60
EndSection

Thank all of you for your help

Edit: I use official nvidia driver with a FX 5600 128 mo. No problem with this?

I'm not clear on whether LCD have HorizSync VertRefresh ranges like CRTs do, but if there is a range, then probably the range should be entered instead of one value. x-x

It definately helps to have the full detailed specification of the monitor to know what types of modes it supports. I always hit a full internet search if it's not clear enough to me. Some website is bound to have exhaustive specifics.

Sorry if I'm just way off base on that, but I also think a bit further down there needs to be settings for defualt resolution, and under the screen section you put a line

Modes "1400x1050"

...for example

What I tend to do is look at the wiki for xorg for any links to example xorg.conf files, and I search the forums. This is better than me trying to remember exactly everything. I tend to always add lines to xorg.conf, and if I remove anything, it's a whole section, like a resolution I know I'm not gonna use, like, I don't know...
1

Who the heck is going to use 1 for a resolution? But you don't have to remove it, I don't think so long as you specify a default resolution like 24 for example and the screen section with that resolution has your size resolution "1400x1050". I think you're supposed to add different sizes to each screen entry for what you might think certain apps need to run in.

There's probably any number of ways to configure it. Xorg7 almost certainly still supports the traditional Modeline entry like you see in the hwd generated file. You see, there isn't just one way. But actually, xorg is trying to move away from the "Modeline" style if they haven't already.

Just know it will work perfectly once you're done stressing over it. Don't stress, xorg is one heck of a cool tweakable file, so you're not wasting your time on something.

I'm probably going to spend tonight tweaking my xorg.conf even though it works just fine, as a matter of fact. Just to see what it can do, or not do.

Hello!

Thank Bysshe for your help.

It work now...

For future noob like me who need help with this problem, here my solution.

I use no modelines in my xorg.conf.
I load ddc, add proper hsync, Vrefresh and my resolution.

Hop and startx.

For those with a nvidia, you can force xorg to be more verbose and view the proper specs for your screen with this command:

`startx -- -logverbose 5`

Check the log after.

With my BenQ at 1680x1050 here my xorg.conf:

Section "Monitor"
        Identifier "Monitor0"
        VendorName   "BenQ"
        ModelName    "FP202W"
        HorizSync    30.0 - 81.0
        VertRefresh  56.0 - 76.0
        # Option            "dpms" "true"
        # Option            "IgnoreEDID"        "true"
        # UseModes    "16:10"
        # 1680x1050 @ 60.00 Hz (GTF) hsync: 65.22 kHz; pclk: 147.14 MHz
        # Modeline "1680x1050_60.00"  147.14  1680 1784 1968 2256  1050 1051 105                                                                                                        
4 1087  -HSync +Vsync
EndSection

Section "Device"
        Identifier  "Card0"
        Driver      "nvidia"
        VendorName  "All"
        BoardName   "All"
        Option "CursorShadow" "true"
        Option "NoLogo" "true"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultDepth 24
        SubSection "Display"
                Viewport 0 0
                Depth     24
                Modes "1680x1050"
        EndSubSection
EndSection

Thank everyone for your help.
