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. -- You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xserver-xorg-driver-ati. https://bugs.launchpad.net/bugs/318325 Title: [X1100] flickering after resume from ram _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
