Thank you all for your pointers! It works (almost) with xorg-server-1.9.2. More questions below ...

I have not added a second screen or anything else. The -configure script seems to have only included my small monitor on the left and it does not mention at all the new DVI. So, I suspect that all the hard work is performed by the kernel hardware driver ... Which brings me to the changes I had to perform on the kernel. The only combination that would allow the above to work involved rebuilding the kernel with CONFIG_DRM_RADEON_KMS=y This caused its own problems - I could not get a framebuffer working during boot and afterwards I could not get a kdm Display Manager showing up. It dropped me back to console. Ctrl+Alt+F7 was not advisable as it locked the machine up, as did restarting xdm. The solution was to remove uvesa framebuffer from my kernel and also remove the following lines from my grub.conf: #video=uvesafb:mtrr,ywrap,1024x768...@64 splash=silent,fadein,theme:emergence quiet CONSOLE=/dev/tty1 Now I get a framebuffer with all my boot messages, but do not get a pretty framebuffer splash or whatever you call it these days. The second problem is that although the screen settings can be applied and take without any problem, they are not retained if I log out/reboot. So, two questions remain: 1. Is there a way of setting up a framebuffer splash with a progress bar and a background image in non-verbose mode when using the new KMS kernel option? 2. How can I save the screen settings so that they persist between boots? I found a script mentioning setting up a configuration file in /etc/X11/Xsession.d/45custom_xrandr-settings: http://www.thinkwiki.org/wiki/Xorg_RandR_1.2#Now_automate_it_on_login but I am not sure if this is a Gentoo compatible way (have not tried it yet). -- Regards, Mick
