Tried with the radeon.agpmode parameter. I discovered that the default setting on my system is 4.
None of the tried settings (-1, 1, 2, 4) did anything to the but I noted that the graphics corruption was different with the -1 setting. I noted a couple of things in my dmesg that I am not sure are important: First, it says that it detects 64M of VRAM and later says that 32M of VRAM is actually ready. Secondly, the aperture size stays at 128M for all agpmode settings except -1, when it changes to 512M. ** Attachment added: "dmesg_grep_radeon.txt" http://launchpadlibrarian.net/45074023/dmesg_grep_radeon.txt -- [RV250] User switching breaks X-session(s) https://bugs.launchpad.net/bugs/565835 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
