higher res in Slack 12

amd0freak · 07-21-2007, 02:33 PM

but i dont understand, why would i want to replace my xorg.conf with a blank file? might i as well just delete all the text in the existing file? would that not result in an inability to init 4?

You'll see each section has an Identifier such as "Monitor0, Videocard0, which are used in each "Screen" Section.
This way you can have multiple monitors cards etc.

If I were you I would start by finding the correct HorizSync and VertRefresh rates for your monitor, it's either found on the back, in the manual or do a google search.

But do start with a fresh xorg.conf by doing the following steps. (This will make a backup of your current conf)

Code:

run xorgsetup
edit the new xorg.conf and change  
Driver "nv" to "Driver "nvidia"
Edit HorizSync and VertRefresh with your proper values.

Try that first or you could also try using EDID to set up your monitor.
by putting something like this in the Device section of your video card.

Code:

    Option      "MetaModes"                "1280x1024,1280x1024; 1280x1024,NULL"
    Option      "UseEdidFreqs"             "true"
    Option      "IgnoreEDID"               "false"

Not sure if both of those last lines are required together or if just one will do it but hey...

as said before!, this shouldn't be needed.
amd0freak: X -configure will create /root/xorg.conf.new . try it!

i did ABSOLUTELY NOTHING more and somehow in nvidia-settings all of a sudden popped up 1280X960

but seriously on a 23" CRT from SUN microsystems, even at its age of 8 years, it handles 1900X1440 LIKE A JOKE (max res is 2550X1760 in Windows XP) and i specified it in the right display as the ONLY res but NOOOo...kde sees all sorts of **** in control center with 150X300 as an option...

amd0freak · 07-23-2007, 07:31 PM

it added a 'metamodes' with 1200X960 so i copied it and changed to 1600X1200 and then again to 1900X1440

x starts fine but none of these new choices are to be found, neither in nvidia-settings nor in KDE control center

amd0freak · 07-23-2007, 08:14 PM

WORKS NOW. not 1900X1440 but thats fine. 1600X1200 works now!

i increased horizrate above the manufacturers rating but it works perfectly

erklaerbaer · 07-24-2007, 07:21 AM

still, you are not using the official nvidia driver, but the open source "nv" driver.

comment Load dri , replace driver nv with dirver nvidia and add

Quote:

Modes "1900x1440"

under Depth 24.

Sorry to come in late on this amd0freak, but I think you might be confusing the 'refresh rate' with the monitor's Synch rates.
The refresh rate is the number of times per second the screen is written to in normal operation. That's what you can change in Windows by right-clicking on your screen etc. There's only one of them.
The Synch rates of your monitor are two, a horizontal and a vertical one. For example my monitor is a 19" CRT (Hitachi CM). At some resolutions I can get a refresh rate of 120.
But its Synch rates (obtained from my monitor's Specifications page), are 31-115 KHz (Horizontal) and 50-160 Hz (Vertical).
It is these last that will enable your screen driver to be set up to run at its maximum rated resolution and refresh rate.
It is these last that need to be supplied for HorizSync and VertRefresh in xorg.conf
Hope this helps....

Just to put in my 2 cents worth

After doing a normal driver nvidia driver install, using the nvidia driver package, I found I had to tweak the Horiz and Vert refresh values around for a while before I got the resolutions I wanted too. But those were the only values I had to adjust. Everything else installed fine just using the nvidia installer, and letting create the xorg.conf file. Without adustment, the highest res it would produce is 1024 x 768.
