w/ Xinerama enabled, Xlib displays RANDR warning dialog

[Chris Miller]

Every time I launch a GUI program from the terminal, I receive the following error message:

Xlib: extension "RANDR" missing on display ":0.0".

I use Xinerama to rotate one of two monitors in a dual-head setup. (AFAIK this isn't possible using TwinView) Upon upgrading from Hardy to Intrepid, I started getting these annoying (and useless) warnings. Other than the warning, everything seems to be working correctly.

As I understand it, xrandr should be disabled when Xinerama is enabled, but that doesn't seem to be happening. Using
   Option "RandR" "off"
in my xorg.conf has no effect. I've attached my xorg.conf attached for reference.

Absent a fix, I'd settle for a method to suppress the error message, since everything seems to be working properly.

I'm seeing the same thing after upgrading from 8.04 to 8.10, with a dual monitor setup and Xinerama. I have this in one of the Device sections in my xorg.conf:

    Option "RandRRotation" "true"
    Option "Rotate" "left"

Because at one time that's how I finally got rotation to work on one of my monitors and continues to work today.

Everything appears to be working just fine, but the same with that error message when I launch GUI programs from the command line.

I'm using the proprietary nvidia driver 96.43.11.

Not a huge problem, just thought I'd throw my $0.02 in.

Hi chrisamiller,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISO CD images are available from http://cdimage.ubuntu.com/releases/)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

[Chris Miller (chrisamiller)]

I can confirm that this bug still exists in the Karmic pre-release beta, installed yesterday (10/25/2009).

New Xorg.0.log attached.

I Can confirm that is a problem in Karmic final release.

This only occurs with certain applications (epiphany, grsync, pidgin to name a few). I am also going to attribute this error with a complete loss of system stability. Whenever any of these programs are running the mouse slows down, mouse clicks work intermittently, and after of period of hours (2 to 24) the system will sieze absolutely.

I have to use flgrx as the ati/radeon drivers will not let me control which screen I want the menu panels.

Here are some useful outputs:

This bug report was filed against an old version of Ubuntu.
Can you confirm whether this is still an issue in natty?

If you don't mind, it would be very helpful if you could update the bug
report in launchpad to 'Fix Released' if it is no longer an issue for
you, or if it is still occurring under natty, please tag the bug 'natty'
so it's easier for us to track.
