Comment 93 for bug 20283

@Martjin va de Streek

I had to revert to the open source "ati" driver since the proprietary "fglrx" drivers, even the latest ones <a href="http://ati.amd.com/support/drivers/linux/previous/linux-rf-cat712.html">Catalyst v7.12</a> and <A href="http://ati.amd.com/support/drivers/linux/previous/linux-r-cat711.html">v7.11</a>, appear to kill suspend and resume on my nw8240. (I'm also using a tuxonice-patched kernel, which may be exacerbating things.)

I am unable to resolve the problem with screen flicker, despite adding the "MonitorLayout" option and adding, Option "DPMS," HorizSync, VertRefresh, DisplaySize to xorg.conf. The flicker, oddly enough, does go away when I suspend to RAM and come back, a detail I've not seen mentioned anywhere else.

Could you be more specific about the fix you are using (i.e. which upstream bug report)? There seem to be several relevant bug reports, i.e. <a href="https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/29357/">#29357</a>, <a href="https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/22985">#22985</a>, and <A href="https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/39762">#39762</a>. Is it a matter of adding the correct options to xorg.conf, or must one use a patched xserver-xorg-video-ati package?

Could you also forward your current xorg.conf if you are using the "ati" driver? My lspci output differs slightly from yours, and I so I am curious if there are different flavors of the X700 chipset out there.
