Discussed this with Marc (the reporter), and I have a T42 with the same radeon chipset, but with 32MB of video ram instead of the T30's 16MB. I can login into the desktop, but after a while compiz dies.
I have this in dmesg: [88457.578314] [TTM] Failed moving buffer. Proposed placement 0x00060004 [88457.578323] [drm:radeon_object_list_validate] *ERROR* radeon: failed to validate. [88457.578327] [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation ! [88461.802935] [TTM] Failed moving buffer. Proposed placement 0x00060004 [88461.802945] [TTM] Out of aperture space or DRM memory quota. [88461.802952] [drm:radeon_object_list_validate] *ERROR* radeon: failed to validate. [88461.802958] [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation ! This is a very serious regression over Jaunty, where X ran well (with a couple of xorg.conf tweaks). In Lucid, this occurs with or without an xorg.conf (the above was from without). This may affect LTS upgrades significantly. -- [lucid] desktop runs out of video memory on ATI Radeon Mobility 7500 https://bugs.launchpad.net/bugs/507148 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 : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
