Had similar problems with the RV410 AGP card. Passing the parameter via grub command line did not work but for me this worked:
echo "options radeon agpmode=1" >> /etc/modprobe.d/radeon.conf update-initramfs -u the last one is necessary to get the option into the initramfs-image. Of cource you can try agpmode=1,2,3.... here as well. -- [RV410] Screen gets unreadable https://bugs.launchpad.net/bugs/559189 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
