Squeeze stable upgrade: "RANDR" missing on display
Erin Brinkley
Xlib: extension "RANDR" missing on display ":0.0".
This happens every time I run a program that opens a new window. Sometimes it makes the program abort. I have my widescreen monitor in portrait mode (rotated), so the display actually WORKS, but I no longer have the xrandr program! So I can't go between landscape and portrait anymore:
$ xrandr
Xlib: extension "RANDR" missing on display ":0.0".
RandR extension missing
$
What in the world is going on??? I've done some research and it is a problem that has occured when people use Xinerama with dual head setups ... however, I am NOT using Xinerama and do NOT have a dual head system. I'm running a single head system with the NVIDIA driver. All worked fine yesterday, then I upgraded to squeeze, got the new NVIDIA driver running, and now this error happens constantly. Is this a bug or do I have to reconfigure something?
I'm pasting some stats here...

Have you considered replacing the nvidia driver with nouveau?

If you are getting the RANDR missing error verify you have the line:
Option "RandRRotation" "on"
Under the nvidia device heading in your Xorg.conf.
I'm running into a different issue which appears related to
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=611619
Best of luck,

Got it. I always had this:
Section "Screen"
Identifier "Default Screen"
Device "nVidia Corporation C51PV [GeForce 6150]"
Monitor "HP L2045w"
DefaultDepth 24
Option "RandRRotation" "on"
Option "Rotate" "CCW"
Option "HWCursor" "off"
SubSection "Display"
I noticed that now I can actually have the RandRRotation line commented off, and it will still start in portrait mode! But I get this horrible error and it prevents some apps to run properly. Again from lots of searches it looks like a common error for people with dual monitors who run xinerama. I'm not in that situation, but checking with "dpkg -l" I see that the xinerama packages are installed, some other library depends on it now! (BUt Xinerama isn't listed in my xorg.conf at all.)

Yes and no. I mean, I would have DEFINITELY wanted to go Nouveau had I known what it was. I was using Lenny for a long time with the proprietary Nvidia driver. Not happy AT ALL that it was proprietary, but the NV driver didn't work with my hardware.
So then I upgrade from Lenny to Squeeze, and found out that my old driver was removed and Nouveau was put in place. I probably wouldn't have cared (actually have been HAPPY that I was 100% free software finally), but the problem was that Nouveau didn't work! The framebuffer console had TINY fonts you had to squint up to the monitor to see, and when XDM started it just crashed!
I thought Oh No and just got rid of Nouveau and downloaded the newest Nvidia driver. (I also have to say that I'm surprised Debian was doing this. Shouldn't it warn the user that it's taking out its X server video driver and replacing with a completely different one??)
It works great, with the exception that RANDR does not work and every time I start an app I get that horrible error:
Xlib: extension "RANDR" missing on display ":0.0".
So now after much web searching and not finding any possible solution, I am willing to try getting Nouveau to work with my hardware. Is there a better place I can go to try and get support for it? I know that when it was installed by the upgrade, I just got a black screen in the F7 window. Should I try to comment out the mode lines in my xorg.conf or is there a config utility I could run? Also, since I used the Nvidia installer now I'm really unsure what I have to remove (by hand) to "uninstall" the Nvidia driver. Or do I just install the nouveau packages?
Thanks!
Erin

The tiny fonts can be altered with
dpkg-reconfigure console-setup
and then
setupcon
I use the terminus 10x20.
XDM crashing could be a configuration issue. Try starting without it.

Try moving xorg.conf out of the way. It isn't needed unless there is
something special you want to do. The nouveau driver should be detected.
