Everything was working with karmic, xorg-edgers PPA and KMS. The issue raised after a fresh install (root formatted, fresh home) of lucid (say beta, I think I installed it on march 26). > Also, try seeing if it works if KMS is disabled - see > https://wiki.ubuntu.com/X/KernelModeSetting Disabling KMS at boot I cannot even use the system: without external monitor I can login, but then everything locks, apart from mouse pointer; booting with external monitor plugged brings a black GDM (dual) screen. In both cases I have to reboot using magic SysReq S-U-B. In attach the Xorg.0.log and Xorg.0.log.old copied using single mode. Nothing worth noting in kern.log. I managed to make things work putting 'Option AGPMode "1"' in xorg.conf; that way I can login and use the system (so maybe a new quirk in radeon/radeon-agp.c is needed). Properly setting the virtual resolution (2560x1024) I could use both monitors and I managed to turn upside down the external one without garbling; changing the resolution (1280x1024 -> 800x600) caused an hardlock (mouse pointer freezed, no magic SysReq keys working). Nothing worth noting in Xorg.0.log and kern.log. I previously forgot to mention that with KMS I get spurious image corruption drawing windows; a window redraw (scrolling, app-switching, ...) solves the problem.
