[ Kind of Solved. ] How to find out HorizSync & VertRefresh

Hey,

I used # Xorg -configure to create a xorg.conf but there wasn't a HorizSync & VertRefresh there. And as the beginners guide said:

Ensure there are horizontal sync and vertical refresh specs under section "Monitor". If not, add them: (...) (If you do not know these specs, consult your monitor's documentation.)

But as I have a laptop there isn't any documentation about the monitor. At least nothing more like the basic stuff that you should lift up your laptop up with it. T_T

I have absolutely no idea how to find this, I tried a lot. Here is some info for how much it matters:
Laptop: Asus A6VA-Q016H ( I use Asus A6VA to search on google since it's a bit more generic, the series are called A6VA )
Model: A6Q00VA

Graphic Card: ATI Mobility Radeon X700

As # Xorg -configure made the Monitor section:

Section "Monitor"   #DisplaySize   330 2100 #mm
   Identifier         "Monitor0"
   VendorName    "AV0"
   ModelName      "1974"
EndSection

Also I choose for # Xorg -configure as that was the one noted in the beginners guide, and the "hwd -x" stated in the xorg wiki article. Only gave this as a result, while I used " pacman -S xf86-video-ati " to install the driver I needed, so haven't done anything with the flgrx driver.

/etc/X11/xorg.conf.fglrx
/etc/X11/xorg.conf.vesa
Your smaple file(s) ready, rename 'xorg.conf'.
If unsure first try 'vesa' (default)

Deleted these files and decide to go for the # Xorg -configure option instead.

If you need any more info to let me know how I can find it out, maybe just tell me what it is I should fill in there or both. Let me know. Thanks for any help I will get.
Hopefully I didn't made this post to confusing as I tried to pump as much information out as I could. =p

Greetings, Mistron.

* I eventually would want to get a 1280x800 resolution, but I don't think I am there yet. ^^ I just want to get this ready "perfectly" first. k

Re: [ Kind of Solved. ] How to find out HorizSync & VertRefresh

Easiest way is to simply let Xorg autodetect. You only need to manually set refresh/sync rates if you're experiencing problems with the autodetected values.

If you must set them manually, the next easiest way is to simply check your monitor's manual/documentation; the refresh/sync rate range will be specified.

Otherwise, there is a formula that I can't remember... something involving display size and resolution.

Re: [ Kind of Solved. ] How to find out HorizSync & VertRefresh

Hey, thanks for your reply. Some last questions about this, how can you automatically let Xorg autodetect this?

Also as I have said, I haven't been able to find any documentation specifying this. I have looked through the whole laptop manual, looked at the Asus webpage and googled around but I haven't been able to find it. Might also be that I am doing something wrong but I haven't spot the things I have been looking for yet.

Any settings that you don't specify in your xorg.conf will be autodetected by Xorg. Simply leave the HorizSync and VertRefresh statements out of your xorg.conf and see if X will start.

Re: [ Kind of Solved. ] How to find out HorizSync & VertRefresh

Just something I found recently...
Pull up the OSD of your monitor if it has one (Using the buttons on the front) and see if they are listed there.
I went through the hassle of trying to figure it out for a few monitors, and once I discovered that many have that information there... Well, facepalm.

Nice, to bad it's a laptop as I have specified. It doesn't have any OSD as far I know. At least wouldn't know where the buttons for that would be. =p

#sudo grep Modeline /var/log/Xorg.0.log

What does that do?

I think I will try to find out what not specifying anything does.
