Second monitor not working after upgrade from breezy to dapper

[Damyan]

I have 1 ATI graphic card connected to a 17" monitor and a Nvidia connected to a 21" monitor. It was working great with Breezy (after spending some time configuring xorg.conf). But now that I upgraded to Dapper I can use only 1 monitor at a time, and the other one remains blank (I can select the main display in the computer Bios because the ATI is a PCI card and the Nvidia is an AGP one). I checked everything and I can't understand why I can not have more than 1 monitor at a time with Dapper when it was working perfectly with Breezy. Here are the relevent parts of my current Xorg.conf:

Re: Second monitor not working after upgrade from breezy to dapper

I just logged in to write a similar post. I'm glad i'm not the only one having this problem.

I've got one video card (Radeon 9200) with two outputs. The display is only on one monitor, but sort of "leaks" over onto the other monitor. It's very odd.

I hope someone has an answer.

Re: Second monitor not working after upgrade from breezy to dapper

I'm not even sure what I did, but my setup is working now, albeit not in the way it was working before.

Before, I had just an extension of the desktop onto the second monitor. Now, it's like two distinct desktops, and I can't move applications from one side to the other. But it's working!

I just totally reconfigured x-server (sudo dpkg-reconfigure xserver-xorg) and then I did:

aticonfig --initial=dual-head --dtop=horizontal --overlay-on=1


And then I added a bit to my xorg.conf, reboot, and walked away. When I came back, I was shocked!

So, I've no idea if it'll help you, but here's my xorg.conf.

Re: Second monitor not working after upgrade from breezy to dapper

If you want to be able to move things from one scrren to the other, add these lines to your xorg.conf:

Section "ServerFlags"
option "Xinerama" "true"
EndSection

Anyway, my problem is still not solved. My case is more complicated than yours because I have 2 separate graphic cards. I would appreciate if someone with a similar configuration succeeded in making it work under Dapper. I also would like to know why something that was working with Breezy would not work with Dapper.

Re: Second monitor not working after upgrade from breezy to dapper

I looked into /var/log/Xorg.0.log and found the following:
...
(EE) ATI(1): Cannot read V_BIOS
(WW) ATI(1): Unable to initialise int10 interface.
(EE) ATI(1): Adapter has not been initialised.
(II) UnloadModule: "ati"
(II) UnloadModule: "int10"
(II) UnloadModule: "atimisc"
(II) Unloading /usr/lib/xorg/modules/drivers/atimisc_drv.so
..

So, the Nvidia card is initialized but the ATI card is not. However, if I start the computer with the ATI card as the default display (by telling the Bios to use the PCI instead of AGP graphic card) then it's the opposite: the V_BIOS of the ATI card can be read corectly but the V_BIOS for the Nvidia can not be read! However, when starting with the ATI, both screens remain blank as soon as the Xserver tries to start (when starting with the Nvidia, the monitor connected to it continues to work normally).

Any idea how to solve this ?

Re: Second monitor not working after upgrade from breezy to dapper - FIXED

The fix was ridiculously simple: I installed the nvidia-glx driver. It now works perfectly.
