    Question Getting Full 1280x768 Resolution of Screen as oppose to lowly 1024x768 Nvidia Drivers???

    Hi all,

    I'm having to use my flat screen TV as my monitor for the time being as I've leant my main monitor to a friend, not a problem it all looks nice and smart on the desk. However, the nvidia driver (or the nouveau) driver cannot obtain an EDID for it as I can see from this snippet of the /var/log/xorg.0.log file

    Code:
    (WW) NVIDIA(GPU-0): The EDID read for display device CRT-1 is invalid:
               (WW) NVIDIA(GPU-0):     unrecognized EDID Header.
    As such I am laden with the default 1024x768 resolution, better than nothing yes, but real hard on my eyes. I have consulted the TV's Manual and the highest (and recommended) resolution is a respectable 1280x768 @ 60Hz. I have tried to play around with xrandr but this seems to result in an error no matter what I try.

    This is a relatively fresh install of OpenSUSE 11.4 coming back after trying 12.1 M1. The nvidia drivers were installed via the suggested one-click method.

    Excuse my waffling on, any help with this will be greatly appreciated, I will provide any other logs etc.

    Yours,

    Tom

    This thread dealt with the same issue successfully.

    Try creating a minimal /etc/X11/xorg.conf like this


    Code:
    Section "Monitor"
    Identifier "Monitor0"
    HorizSync 45.0 - 50.0
    VertRefresh 50.0 - 65.0
    EndSection
    
    Section "Device"
    Identifier "Device0"
    Driver "nvidia"
    EndSection
    
    Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    DefaultDepth 24
    Monitor "Monitor0"
    Option  "metamodes" "1280x768"
    SubSection "Display"
    Depth 24
    Viewport    0 0
    EndSubSection
    EndSection

    Hi Deano,

    Thanks for the reply, I came back to post that I have encountered success by doing exactly what you have pointed me to I've bookmarked the thread in case I encounter an awkward screen in the future.

    Thanks very much,

    Tom

    Thanks for the update Tom. I'm sure this will help others with nvidia hardware and EDID issues. There is development of SaX3 currently, which may provide a graphical means of doing the same thing. (At least I hope it will).

    Thanks deano_ferrai for your support in Graphical resolution issues in MANY threads in addition to this one. MOST appreciated.

    I also have hopes for sax3, but I am concerned it may not have all features that are not too difficult to implement as the coder (of sax3) may not know of all the solutions users like yourself understand. Unfortunately I know of no way to feed such suggestions to the coder. Nor do I know if they are even interested in learning of the resources we have of users who may be able to help with ideas/possible solution methodology (that may or may not be codeable).

    Thanks for the kind words Lee. I saw your link concerning the update for the sax3-gsoc weekly update:

    SaX3 – GSoC 2011 – Weekly Report 2

    and left a message, which I hope Manu Gupta will read. I know that there are many tricks/tips concerning X.Org configuration, some of which are driver specific. However, I'm sure that whatever stage this code gets to, this will provide a useful framework on which to build if necessary.

    Nor do I know if they are even interested in learning of the resources we have of users who may be able to help with ideas/possible solution methodology (that may or may not be codeable).
    Most of the config tweaks are fairly easily code-able, however because of the ever changing development of the graphics dirvers, the config solutions can vary accordingly.

    Hi I am definitely interested in your experience.. for graphic cards and monitors and others. I want to get a bit of configuration files experience before actually turning to them.

    Great news and I wish you all the best in your efforts. Deano_ferrai and also please_try_again are pretty good at doing this sort of tuning, so they are likely the users whose threads providing help will save you the most time in monitoring.

    Again, good luck in your efforts. Many of our users are excited about this.

    Hi all,

    I'm glad to see that this thread is still getting attention, as I have another problem ha ha. Okay, so I have sorted the resolution problem by using the cvt util to create a modeline and then manually adding it to the xorg.conf I kindly asked nvidia-settings to generate for me as suggested by deano. However, even though I am using the recommend refresh rate of 60Hz it is incredibly fuzzy and seriously strains my eyes whilst reading. However, if I change the refresh rate to a lower 50Hz all is beautiful, apart from the missing section from the left hand side. My question is this, are there any tools that enable me to compensate for this, other than nvidia's overscan? Which only seems to hurt more.

    I'd like to say that I, myself am looking forward to SaX3, as I loved SaX2 as it was a major part of me getting used to Linux back when I was 14/15, I thought it was marvelous that OpenSUSE 10.3, particularly the SLICK variant came with everything, including a tool to get your screen looking nice and tidy.
