Yes unfortunately the problem is radeonhd is incompatable with KMS which is the default for the radeon kernel module. If you want to use radeonhd you will have to disable KMS
You can see it is in use and causing the issue here from your log - (II) RADEONHD(0): Found radeon drm 2.0.0. drm 2.0.0 is used when KMS is in use, otherwise it is 1.x.x. If you want to use radeonhd over radeon for some reason (it's highly not recommended though!) then you can use these steps to disable KMS. sudo nano /etc/default/grub. Add radeon.modeset=1 to the end of the line GRUB_CMDLINE_LINUX_DEFAULT=. Then sudo update-grub and reboot. ** Summary changed: - [RV515] Thinkpad T60: black screen after booting until X is restarted manually + [RV515] radeonhd is incompatible with KMS. -- [RV515] radeonhd is incompatible with KMS. https://bugs.launchpad.net/bugs/568035 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
