This problem seems to be based in Kernel Mode Select and the hardware involved. Bug report 288807 talks about some hardware issues with Sony laptops and that may be in effect here. I believe KMS is now on by default in Karmic for Intel devices.
To get the system fixed was fairly simple in the end and only requires updating Grub to turn off KMS. I am using Grub2 on this install. On a live cd boot, use F6 to edit grub. Remove “splash” and replace with “nomodeset”. I included “--xdriver=intel” on my system as bootup seemed smoother with this added. Splash does not work with nomodeset so it needs to be removed. On an installed system, edit /etc/default/grub to remove splash and add the ‘nomodeset xdriver=intel” line and then update grub. gksu gedit /etc/default/grub Change the line: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” To this: GRUB_CMDLINE_LINUX_DEFAULT=” nomodeset xdriver=intel” The “quiet” option may work but I did not use it. The “xdriver=intel” was correct for my system. Then run: Sudo update-grub Note, I did not need to have any xorg.conf in the system to get it working. There did not seem to be any difference whether it was there or not. It might be good to have a fallback “nomodeset” option as a standard part of the grub menu till KMS can develop a way to deal with this hardware. -- Screen resolution not correct https://bugs.launchpad.net/bugs/459547 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
