[SOLVED] ATI Radeon X1550/X1650 Dual Head Video Card

[anon222]

Hi group....

I recently acquired an ATI Radeon X1550/X1650 dual head video card that I wanted to try and replace my old nvidia dual head card. The hardware scan calls it a X1550, however the internet search says it is a X1650.....it has dual DVI port on board. The pci nvidia card worked ok, but was kind of jittery video playback and sluggish on moving programs back and forth between screens. I was hoping this PCIe Radeon X1650 card would be an improvement with 256MB RAM.

However, I tried to run the Install Drivers option and the new video card is not being discovered for installing drivers.

How can I run this ATI Radeon X1550 card and how would I best remove the Nvidia X server option that was installed with the previous card I was using?

Thanks in advance..........

Did you uninstall nVidia drivers before replacing the cards?
If you haven't that is the culprit.
When you uninstall the Nvidia, on rebooting , you would revert to the open source driver.
The proper procedure for replacing the nVidia with AMD/Ati graphics card would be:
Uninstall the nVidia driver, shut down, remove the Nvidia card, install the ATI card and reboot, you should start with the default open source driver for your ATI card.
If you still have that Nvidia card, you could install that card again and this time remove the drivers with the graphical tools. That's the easier way.

The second option is to set "nomodeset" kernel option as a temporary solution/workaround until fixing the graphic card.
Once in on the desktop environment remove the additional drivers already installed for Nvidia, reboot.
If you get a blank screen set nomodeset kernel option again on bootup and innstall the Ati drivers.

Your New graphics card might be a bit old. Check the legacy part in the manual. Maybe AMD doesn't include it in the latest drivers.
If you don't want to use the open source drivers you might need to download and install legacy drivers from AMD website.
