The X Server does not support the XRandR extension

Until recently i was using Ubuntu 7.10.
The graphics were fast.
Days ago I did an upgrade to Ubuntu 8.04.
Since then:
I can still use 3d environment effects, but the screensaver for example runs extremely slow
By trying to set the screen resolution, i get this massage
"The X Server does not support the XRandR extension. Runtime resolution changes to the display size are not available."
I use Ati radeon 9600 and i was using the Ati radeon non free driver.
Any help?

I am having same problem as "xodroolis" is having.
My system details are-
Intel D101GCC mother board with ATI Radon Xpress 200 series on board graphics card.

Previously, i.e. when i was using Ubuntu gutsy i was able to change the resolution but recently, when i upgraded to hardy i am getting error on selecting the "Screen Resolution" menu option. The Error state that "The X Server does not support the XRandR extension".

Dose any one knows how to solve this problem?

Hello xodroolis,
I think that i have solved our problem.

I applied following steps after opening up terminal & in home folder.

1) Create a xserver-xgl directory in .config folder.

Code:

---

gajanan@khandake:~$ mkdir .config/xserver-xgl/

---

2) Move to just created xserver-xgl folder.

Code:

---

gajanan@khandake:~$ cd .config/xserver-xgl/

---

3) Create a file named disable

Code:

---

gajanan@khandake:~/.config/xserver-xgl$ touch disable

---

4) Check that file is correctly created.

Code:

---

gajanan@khandake:~/.config/xserver-xgl$ ls -l
total 0
-rw-r--r-- 1 gajanan gajanan 0 2009-08-11 14:29 disable
gajanan@khandake:~/.config/xserver-xgl$

---

5) Then restart x-server by pressing

Code:

---

Ctrl+Alt+Backspace

---

6) Log into the system and Check out

Code:

---

System->Preferences->Screen Resolution

---

and it is working now. :P

Thanks to PeterPall Soultion #24 at launchpad.net with Bug #199359, no more "The X Server does not support the XRandR extension" for me.

xodroolis or any one who is applying this solution please confirm it here if if worked with you

Thank you!

Worked for me on RHEL5.7...
