Comment 56 for bug 318325

On this Acer Aspire 5100 I just tried the following:

  -- disabled KMS using # echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf
          but disabling KMS had no noticeable effect on flicker.

  -- tried vesa driver by creating an xorg.conf
         The vesa driver came up in low resolution, AND the machine flickered after suspend.

  -- tried fbdev driver by creating an xorg.conf
         The fbdev driver didn't work with X at all; X wouldn't start.

All of the above was tested using the stock Maverick 10.10 xorg, NOT the newer PPAs. When I get a chance I may try the Xorg Crack PPA.

I consider suspend and resume essential on a laptop, so I am open to suggestions for other things I might try.

P.S.: I believe this particular laptop only contains the stock 1Gb RAM.
