--- Comment #40 from Martin Stolpe <[email protected]> 2010-06-09 00:01:33 PDT --- If I can remember correctly the vga= option in grub will load a framebuffer driver which conflicts with KMS. That's the reason you have to remove this option. The nomodeset option disables kms and radeon.modeset=1 enables it. For modesetting to work you have to remove the nomodeset option. I think you have to add the radeon.modeset=1 option with the kernel you're using. You can try to add "radeon" and "fbcon" to /etc/modules.autoload.d/kernel-2.6 it they're not included there. If this still doesn't enable KMS you can try the following (I think this doesn't really belong to a bug report about Xorg but anyways...): -Unmask the 2.6.34 vanilla kernel sources and emerge them as described here: http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=7. -get "microcode_core-xen.patch" and "http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.34-1.tar.bz2"; and "config.xen" or "config.xen.x86_64" from here: http://aur.archlinux.org/packages.php?ID=29023 -apply the patches to your source (which should be in /usr/src/linux) -copy the corresponding config file (64 bit: config.xen.x86_64) to /usr/src/linux/.config -configure your kernel with "make xconfig" as described in the Gentoo documentation. Make sure you have "Enable modesetting on radeon by default" enabled in "Direct Rendering Manager...". In "general" change "Local version - append to kernel release" to a string you like (e.g. "-xen-kms") -install the ucode firmware files Install the kernel as described in the documentation and create a new grub entry. Cross your fingers and boot into the new kernel. If there are problems using the new kernel (eg. Firmware are missing) I have to refer you to the Gentoo people. For later reference: You can blacklist drivers in /etc/modprobe.d/blacklist If you really want to try Archlinux you can use the packages in the repositories. You shouldn't have to configure anything (There is a nice install guide: http://wiki.archlinux.org/index.php/Official_Arch_Linux_Install_Guide and this one http://wiki.archlinux.org/index.php/Beginners'_Guide). When you want to have a kernel with Xen support you have to use the package in AUR which I mentioned earlier. Have a look at http://wiki.archlinux.org/index.php/AUR#Installing_Packages_from_the_AUR. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
