CentOS 6.3 – Unsupported Video Hardware

CentOS 6 Comments

I pulled one of my old OQO model 2 out of the junk bin and installed CentOS 6.3 over CentOS 5.3.

The internal video does not work in graphics mode (text works fine), though a monitor attacked to the VGA port works fine. Although my intension is to use this as a portable test server, it would be nice if the video was available. How might I go about figuring out the Xorg magic to get it working?

  • There is no xorg.conf. This is a fresh install of CentOS 6.3; I
    removed the old 5.3 partitions and did a total from scratch install.

  • When you say “internal video does not work”, what do you mean?
    Is the laptop screen black, garbled, flickering, unresponsive?

    If black, did you try startx for the command line?

    Are there any errors (EE) or warnings (WW) in /var/log/Xorg.0.log?

    Anything in /var/log/messages or dmesg?

    What is the output of lspci | grep VGA?

  • Scrolling flickering, blue and white image.

    Have not switched to init 3 to try.

    (EE) open /dev/fb0: No such device

    (WW) Falling back to old probe method for vesa
    (WW) Falling back to old probe method for fbdev
    (WW) CHROME(0): Manufacturer plainly copied main PCI IDs to subsystem/card IDs.
    (WW) CHROME(0): Unable to estimate virtual size
    (WW) CHROME(0): [XvMC] XvMC is not supported on this chipset
    (WW) Lid Switch: Don’t know how to use device

    what would I search for?

    01:00.0 VGA compatible controller: VIA Technologies, Inc. CX700/VX700
    [S3 UniChrome Pro] (rev 03)

    Hope this points somewhere.

  • Error messages pertaining to the video controller.

    Use the info in this line (VIA CX700 VX700 or UniChrome Pro) to do a google search. Add linux to the search terms to see what driver you need.

  • I had another oqo2 in the dustbin with C5.3 on it. I powered it up and it came up in init 3 mode. When I did startx the external monitor came up nicely, but the system’s screen was white.

    Then I remembered (they have been in the dustbin for a few years).

    I never got the video working back on C5.3. In fact I had to play around with xorg.conf to get better than 800×640 for the external monitor, so C6.3 is an improvement.

    So no driver that I can find. Oh well. They will just be little servers for testing.
