Artifacts with Catalyst 9.4 x86_64

Fglrx can only use XAA. That option only works for the open source drivers. By the way, no artifacts for me on Jaunty 64bit (GNOME), HD4850 w/ 9.4/9.5.

Great. Barking up the wrong tree then.

I have HD3200 (Gigabyte 780g motherboard).

Everything seems to work fine other than these random horizontal lines.

How can I do that? Please provide detailed explanations.

In the "Device" section (section where you have Driver "fglrx") of /etc/X11/xorg.conf, add this:

Option "AccelMethod" "xaa"

and restart X or reboot.

Can someone set the AccelMethod to xaa instead of exa and see if the flicker disappears?

How can I do that? Please provide detailed explanations.

Thank you,

What of the new Catalyst 9.5? Did anynone still experience the flickering? I haven't tried yet.

There is no change. It's the same for me..

I don't have access to the hardware right now.. so I can't try out the exa/xaa part. Can someone verify?

I get this all the time. Right from the kdm login screen.

edit2: oh, I'm running Ubuntu 9.04 AMD64 (x86_64) as well.

Yes, it occurs only with the x86_64 architecture. I know for sure because I was running a 32 bit environment before and those artifacts weren't occurring.

Actually I think I've seen this too, where portions of the page in Firefox will go black. It's not limited to Firefox. I think I've seen it happen with gEdit as well. This wasn't limited to ATI, as it happened with nVidia as well, same system. nVidia 180 drivers, 7900GT. ATI 9.4, HD4770.

Not sure how to reproduce it exactly, I'll keep my eye out for it. Very random.


edit: causing that part of the display to update with scrolling or highlighting text would correct the issue.
