The change between Ubuntu 9.10 and 10.04 most likely to have caused this was enabling KMS by default on your card. You can disable KMS for one boot by adding “nomodeset” on the kernel commandline, after “quiet splash”.
To edit the kernel command line you need to press ‘e’ at the GRUB menu. If the GRUB menu doesn't normally appear for you (by default it only appears if you've got a dual-boot setup) you can make it appear by holding down “shift” during the early boot process, just after the BIOS boot screen. If booting with “nomodeset” fixes the screen problem, it would be good if you could attach the /var/log/Xorg.0.log file. It would also be good if you could boot with the FW900 monitor attached, adding “drm.debug=0x04” instead of “nomodeset” to the kernel commandline. That will make the kernel print out lots of debugging information. Since the screen won't be usable, you'll have to reboot. The debugging messages will be saved in /var/log/messages, which you should attach to the bug. There is sometimes some sensitive information in /var/log/messages, so I'm marking this bug as private until we've inspected it and extracted the debugging logs. -- Can't install when Sony FW900 is connected https://bugs.launchpad.net/bugs/572104 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
