So bear with me.
There is no grub.cfg file in my configuration. Rather the equivalent information appears in menu.lst. I believe this has to do with whether grub 2 or 1 is used. I don't know much about either version or what I would need to do to migrate. It has taken me long enough to learn how to manipulate menu.lst. I would rather not have to complicate my life by learning an alternative configuration technique. Looking at my copy of menu.lst I see the text that you suggest changing. Specifically the menu.lst entry for the Karmic Koala kernel is: title Ubuntu 9.10, kernel 2.6.31-14-generic root (hd1,0) kernel /boot/vmlinuz-2.6.31-14-generic root=UUID=f900070e-2701-4360-98c3-68bc817d012b ro quiet splash initrd /boot/initrd.img-2.6.31-14-generic quiet I see the release note item "No Xv support for Intel 82852/855GM video chips with KMS" which suggests "nomodeset" although the problems reported here are completely unrelated to what I am observing. It took me a lot of hunting around to understand what was actually being suggested, as the vast majority of relevant pages just assumed that everybody already knows what KMS was about. Please correct me if I am misunderstanding this: In Karmic Koala screen mode setting has been moved by default from X11 down into the kernel in order to fix a number of problems. However it would appear that there are some minor problems in the kernel code with respect to some Intel video chips. The chipset on my computer is even older than the ones mentioned in the 9.10 release notes. Changing the kernel setting to "nomodeset" forces the old functionality in X11 to be used rather than the new kernel code. -- Jim Cobban jamescob...@sympatico.ca 34 Palomino Dr. Kanata, ON, CANADA K2M 1M1 +1-613-592-9438 -- hang in Karmic Koala https://bugs.launchpad.net/bugs/477918 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
