Fedora 15 NVIDIA external Samsung SyncMaster… finally!

Ever since Fedora 15 came out, I couldn’t get my external monitor to work with my Lenovo W520 laptop which has an NVIDIA Quadro 1000M graphics adapter. I am using the proprietary driver and no matter what settings I would choose, I’d always get a nasty “Oops, something went wrong!” error message when logging in. I knew that there shouldn’t be a problem as I dual boot into Win7 and the external monitor was working fine.

Today I tried a few more combinations and finally got it working, most probably because I have chosen “TwinView” in the configuration, rather than “Separate X screen”. I also specified each screen’s resolution and refresh rates instead of leaving everything on “Auto”. Further settings include:

  • Screen 0: Absolute Position +0+0
  • Screen 0: Make this the primary display for the X screen
  • Screen 1: Position +1920+0 (where 1920 is the width of the laptop display)

My setup is perfect again.

    Can you please email me at ‘snip’ your xorg.conf file used in Fedora 15 that made the Quadro 1000m work with external displays ? Did you use display port or Analog VGA to connect to external monitor ? I have the exact same problem since I got my W520 and so far the proprietary drivers downloaded from NVidia do not start the X-Windows properly. If what you describe is the real fix then its a great find… Thanks.

    Thanks,

      Hi Raj,

      I will email you my xorg.conf file shortly, but I have also put it here for anyone else who might need it.

      I am using Analog VGA and this file is as generated by `sudo nvidia-settings`. I have not edited or added to it in any way whatsoever.

      Hope this helps.

      Chris.

    I asked Raj very politely to copy/paste his email response here for everybody’s benefit, but it seems it was too much to ask! So here it is:

    Hi Chris,
    Thanks for your help. It really worked ! The trick I found is that we must execute “Xorg :1 -configure” to let the system generate a new xorg.conf which then works effectively with proprietary nvidia drivers on Linux x86_64. Trying to use the xorg.conf created by nvidia installer does not help. That was the missing piece of information which is causing so many to assume that the driver does not work properly on W520.
