I haven't tried your suggestions yet. At first, I didn't think this could be a heating issue. The reason for this was twofold. First, I hadn't explicitly followed the instructions in the ACPI Guide, so I figured that because of this maybe it was causing some "wonky" behaviour. Second, I had the laptop into Dell 6 months ago and they did extensive diagnostics and ultimately replaced the fan. However, I changed my thoughs after reading some of the replies in this thread, most of the unified assumption that it *was* a heating issue. Also, when I was doing the original install of the Gentoo base system, I selected to have ACPI built into the kernel, but didn't change any of the defaults that were selected in genkernel. Hence, I was trying to rebuild prior to following the remaining instructions in the ACPI Guide and the laptop shutdown in the middle of the kernel build. Luckiy, on reboot, it defaulted to the good kernel build. Anyway, because of this, I gave up last night. I guess when I initially tried to build xorg-x11 and it bombed, I never let the laptop properly cool down. I retried tonight and successfully got the new kernel to build and am now creating the scripts as directed in the ACPI Guide. Once I've done this, I will try again with building xorg-x11 and will try the above suggestions. Thanks to all who replied to this. I'm really hoping that I can get Gentoo installed on my laptop. For me, after trying Gentoo, everything else pales in comparison! Regards, Colleen -- gentoo-user@gentoo.org mailing list
