I have a Lenovo ThinkPad W500. This features a 'ATI Technologies Inc Mobility Radeon HD 3650'.
I didn't manage to start the Natty 11.04 live CD, nor install Ubuntu in any way, due to a kernel oops (same as shown in comment#3) The trick was to go into BIOS and enable the "Integrated graphics" (thus not use "Discrete graphics" - the ATI card, nor "Switchable graphics") and also on the same page disable the "automatic detection of switchable graphics for supported OSes" option. With this, it was dead simple to install. But the integrated graphics apparently couldn't handle two external monitors, only one external and the laptop screen. Adding 'drm' and 'radeon' to /etc/modprobe.d/blacklist.conf as described in comment#4, and going into BIOS and set it to Discrete, the system booted up just fine, now detecting and handling the three screens (two ext + laptop) fine. (I cannot get all three screens up at the same time, though - only any two). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/761721 Title: Computer unbootable after Natty install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/761721/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
