X Defaults

CentOS 6 Comments

I’ve been trying to move from CentOS 7 to fedora. My monitor is 1440×900, but fedora only believes it’s 640×480. Grrrr. xrandr has not helped. I’ve been trying to write X configuration files to tell fedora 1440×900, but no joy. Is there a way to get X to tell me its current beliefs, very preferably in configuration file format?

According to the log file on CentOS, everything was defaulted or probed. It contains no numbers. My guess is that fedora has different defaults and they are wrong for me.

I’ve had problems like this before, so I’m unwilling to install until I know I can run a live version. That makes life clunky. I have to boot to non-graphics, do my editing and change the runlevel.

  • 1. What kind of video card is this?
    2.How is the video connected to the monitor? (DVI/HDMI/DisplayPort/VGA)
    3. What kind of monitor is it?
    4. What version of Fedora and is Fedora trying to do X or Wayland?

    Sometimes if Fedora can only go to generic 640×480 the video card is no longer ‘supported’ by the various X11 drivers.. or the data that the monitor is returning to say what it can support is coming back as 640×480. Finally this may do better on a fedora mailing list (but they will ask the same questions). For a CentOS viewpoint I would ask if it happens if you run CentOS-8 (try via a live cd) on the box. If it does happen, then it is a problem between Fedora-18 and Fedora-28. If it doesn’t happen then it is a problem between Fedora 28 and the version of Fedora you are trying.

  • Is a CentOS 8 live image available anywhere?

    I would love to have one for hardware compatibility testing when looking for new laptops and such.

    Fedora 32, X

    IIRC CentOS 8 does not have a live version. I expect Fedora-18 to 32 do.

    Just rediscoverd Xorg –configure . Do not remember how I used it. Not sure how I should.

  • OK most of the references I see to this card are before 2014, so I am not sure if this gets any testing in Fedora anymore. The resolution on the monitor is ‘odd’ compared to what the various drivers are listed to support
    (640×480, 1024×768, 1920×1080) so again I am not much help here.

    Fudge, I should know that. Sorry for a wild goose chase. I would see if the CentOS8 installer goes into X with a larger than 640×480

    Yes.. that might help figure out in a binary search method.. though downloading archive isos might be a lot to ask.

    I don’t remember using it since 2004 so I’m not sure myself. I am sorry I
    can’t be of more help.

  • I just managed to install to an SD card. Default CentOS 8 gives me 1440 x 900. Installing to a removable drive would seem a useful substitute for a live CD.

    At one point CentOS 8 or Gnome gave me a screen with a big date and time on it. Could not figure out what to do with it. Had to reboot.

    This, for me, is usually the screensaver. I pull the screen up with the mouse or press the space bar.

    Thanks
