sax2 error: cannot deactivate all displays

I’m running Suse11 and have just installed my video driver for the ATI Radeon 9550 via the one-click install. At first the catalyst center wouldn’t open, telling me I didn’t have a driver installed. Sax2 showed the graphics card and the correct monitor (LG1917) and correct resolution.
Trying to run the compiz deskop effects were received with a blank black and then white screen.

After googling I read a few times that I had to type “aticonfig --initial” after installing the ati driver.
My screen wobbled a bit, and the resolution was changed to 1440x900 and the monitor is now showing as ATI.
When I start Sax2, I get the error message “Cannot Deactivate All Displays - At least one display must be active”.
When I try and change the monitor from ATI back to the LG and the correct resolution I get the following message

Saving Configuration Failed
The following report has been created:
SAX library: Success
X configuration: Data incomplete in file /var/lib/sax/xorg.conf
Undefined screen “aticonfig-Screen[D]” referenced by Server Layout “Layoug [all]”.

The catalyst control centre now works, but I can’t change the monitor in there and setting the correct screen resolution doesn’t work in there either.

Any help is greatly appreciated

I’m having the same problem, except with ATI X600 on my Acer laptop. When I first installed Suse and tried to enable compiz, I got white screen, after a lot of surfing, and installation dvd I managed to remove compiz and fglxr drivers and I got my desktop back. Then I downloaded ati drivers from their site and installed them, now I can’t change the screen or enable 3d in SAX2. I get the same Error. I tried editing xorg.conf file, but after I start sax2 it changes back. Also when I start sax2 I get: Cannot deactivate all displays At least one display must be active.

Hi there,

I just had the same problem today. I installed the ATI drivers and typed in “sudo aticonfig --initial”. After I restarted X, Sax2 was giving me the same message “Cannot Deactivate All Displays - At least one display must be active”

To fix this I had to configure Sax2 to use the new ATI driver.

> su
> your password
> sax2 -r -m 0=fglrx

It fixed it for me. :slight_smile: But read the instructions, they are from here. ATI - openSUSE

Step 4 - Configuring the newly installed ATI driver

After the driver has been installed it now needs to be configured. Run this command after you have installed the driver.

sax2 -r -m 0=fglrx

This forces sax2 to use the fglrx driver. Setup your resolution and save and exit

Attention: If you have ati radeon x1650 then you may want to skip previous command because sax2 doesn’t make correct settings. You should run sax -a before installing the driver and after installing driver just run following command:

aticonfig --initial input=/etc/x11/xorg.conf

And after that you should modify xorg.conf by yourself.

Attention: If sax2 goes to a blank screen then try the below method, if that doesn’t work, follow the the steps from the Troubleshooting section.

Actually forget that, it worked until I restarted, now I’m presented with a lovely blank black screen when I turn on the computer…

AAAGGGHHHHHHH!!! >:(

PLEASE DON’T LISTEN TO MY ADVICE ABOVE IT WOULD PROBABLY GIVE YOU THE BLACK SCREEN PALAVER.

Ok, I fixed my black screen by booting with init 3

Then I used the commands:

> sax2 -r -m 0=vesa
> init 5

This reverts it back to default, then I installed my good old ATI repo drivers from the opensuse - 1 click install.

> sudo aticonfig --initial
→ CTRL+ALT+BACKSPACE

login again…

and BAM, I was back to normal.
