Thank you for testing. I also have no idea why KMS and ACPI seem to be related. Just thought it would be nice to know for the upstream developers if turning off ACPI helped. If it doesn't work, it doesn't work.
Actually, if you back out of xorg-edgers and back to standard Karmic, you should be able to run without KMS, since UMS support was dropped only after the driver in Karmic. You can use the ppa-purge script for that (`sudo apt-get intall ppa-purge` will pull it from the xorg-edgers PPA, and running `sudo ppa-purge xorg-edgers` will remove everything from xorg-edgers exept ppa-purge itself). Now with standard Karmic drivers (and both with Karmic kernel and mainline kernel) - check if it still freezes with the kernel option "nomodeset" [*] - check if it still freezes with the kernel option "acpi=off" It may be that acpi=off turns off KMS and that is the reason it helps, but if it freezes with nomodeset and not with acpi=off, that would be interesting. I think the "low graphics mode" problem you are having may be one of the bugs mentioned in this post: https://lists.ubuntu.com/archives/ubuntu-x/2009-November/000650.html (the ones about gdm). [*] I looked if you had already done this, but at least I couldn't find it. It is in situations like this it is really not helpful to have other people reporting what they have tried. Makes it harder to find what you did. -- [i855GM] Freeze shortly after X startup on Intel i855 https://bugs.launchpad.net/bugs/447892 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
