Thread: Setting screen resolution in Suse 11.3

  1. #1

    Default Setting screen resolution in Suse 11.3

    I just installed Suse 11.3 64bit on a new build. My video card is a nvidia gt240. I am using the default drivers. My monitor is a NEC 17" LCD.

    When I boot up the screen resolution defaults to 1280x1024. I can go to applications>configure desktop>display and set it to 1024x768, which is my resolution of choice, and it works until I reboot or log out and log back in, then it resets to 1280x1024.

    I would like to make 1024x768 the default so I don't have to keep changing it. Is there a way to do this? The output of xrandr looks like this:

    $~> xrandr
    Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
    DVI-I-1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 338mm x 270mm
    1280x1024 60.0 +
    1152x864 75.0
    1024x768 75.1 70.1* 60.0
    832x624 74.6
    800x600 72.2 75.0 60.3 56.2
    640x480 72.8 75.0 66.7 60.0
    720x400 70.1
    HDMI-1 disconnected (normal left inverted right x axis y axis)
    VGA-1 disconnected (normal left inverted right x axis y axis)
    Is there something I can change to set a new default resolution?

    The config files are located here:
    /etc/X11/xorg.conf.d

    Thanks caf4926, but I am afraid I am still stuck. The guide goes way over my head with run level 3 and deleting my video drivers and then installing different drivers.

    I found the /etc/X11/xorg.conf.d folder by starting at the root folder and navigating to it. Inside is several files, including one "50 monitor.conf". The output of that file is as follows:

    Section "Monitor"
    Identifier "Default Monitor"

    ## If your monitor doesn't support DDC you may override the
    ## defaults here
    #HorizSync 28-85
    #VertRefresh 50-100

    ## Add your mode lines here, use e.g the cvt tool

    EndSection
    Is there something I can add in this file to set my monitors default resolution? I don't know what a mode line is, or a cvt tool. I have spent quite a bit of time with Google on this problem but I don't really seem to find anything I can do short of going back to school for several years to learn computer programming. At 58 years of age I really don't want to do that. I just wanna surf the innernets.

    Can I just ask
    Is the default resolution that you get incorrect or are you just wanting something at odds with the default?

    I'm not sure I'm the best to advise editing those files because I have never had to edit them (in 11.3 at least)

    BTW
    You might want to consider installing the proper nVidia driver rather than using the default nouveau

    OK caf4926, I'll add the nvidia repo. I appreciate the help on this. I've spent quite a bit of time with Google researching this problem, I am not sure anyone has ever really fixed it, although it seems to be a common problem with 11.3. Can I just install the NV drivers without deleting the nouveau drivers first?

    I have used various distros of Suse for years, dating back to when it was SuSE and from Germany before Novell bought it. My last was 11.1, before that 10.0, before that 9.2, which was one of the best, rock solid and it just worked. Thing is, in all of them from 9.2 up I was able to set this same monitor to 1024x768x60. And it always stayed set. 11.3 won't stay set. For me and apparently a lot of other people. SaX is gone, and the auto configuring replacement doesn't work very well. The really ironic thing is that most of the other people complaining about this problem have their system defaulting TO 1024x768 and want to change it to something higher. mine is the opposite.

    I suppose I can just set it every time I boot up, just takes a few seconds, and I leave my computer running for months at a time anyway so it isn't really that big of a deal. But it is still an annoyance in what is otherwise a very nice distro. I hope this gets ironed out in 11.4. That should come out about the time SSDs become affordable enough for even a cheap old geezer like me.

    Just looked through the thread you linked, that is some good info. I will go over it tomorrow and decide whether or not to use the nvidia drivers. Things are working now and I don't want to lose my setup.

    Thanks again.

    Hi fstreed

    I'm not sure why you would want to choose another resolution below the native one for your monitor, as it usually results in a blurry looking display. However, you can just add an entry entry to /etc/X11/xorg.conf.d/50 monitor.conf like this

    Code:
    Option "Preferred Mode" "1024x768"

    The following thread explains:

    I can't change screen resolution in suse 11.3

    Some users choose to create a minimal /etc/X11/xorg.conf file, but it will still work if you edit 50-monitor.conf instead.

    If you decide to install the nVidia driver you can then use Yast to install nvidia-settings then open a terminal and as su type nvidia-settings and you'll get a very simple GUI tool that'll even save to the config file as an option.

    Mr. deano_ferrari, you sir, are a true hero. That was exactly what I was looking for. It worked great. Thank you, sir.

    I need the 1024x768 resolution because at 58 my eyes aren't what they used to be, at higher resolution it is hard for me to read text. This monitor supports this resolution just fine so I use it. Perhaps I should get a bigger monitor, a 17" with a 4 to 3 aspect is kind of small these days.

    This forum is great. Thanks guys.
