?Ubuntu 12.10 Boot Issues
Hi all, I was on an old version of Ubuntu, started getting messages about it not being supported any more and so decided to update. I decided to install the lubuntu-desktop package, then do updates until I was up-to-date. So now, I'm up to Lubuntu 12.10. When I booted it, it hang big-time before getting into the GUI. I Hard-booted and selected a different kernel, and it booted fine. After experimentation it seems that booting into the kernel described as "Ubuntu 12.10, kernel 3.5.0-10-generic" causes the machine to hang before getting into the GUI. I've just tried making LUbuntu and XUbuntu 12.10 CDs and booting from them, but both of them hang, I presume when trying to load the Kernel. Trying to boot via the "kernel 3.5.0-10-generic recovery mode" boot menu option also hangs. I've not had a problem like this before. Does anyone have any advice on diagnosing what's causing this hang? Any logs to examine would have to survive a hard-reboot, or are there any debug options I can put on the grub boot line. Or am I doomed, or have to wait for a new kernel to come out, or keep using the old one. Any advice or comments would be appreciated. I haven't googled much as I don't quite know what to search for (you may tell me I'm a numpty for this!) Hardware is a Dell Lattitude D410. Cheers Steve

Steve Dell often use odd hardware, particularly in their laptops. See https://help.ubuntu.com/community/BootOptions for a discussion of how to change boot options.

Thanks Mick, I'll have a look later. I feel I should add that this particular laptop has been running on various versions of Ubuntu successfully for several years - this is the first such problem I've had. I suspect that some hardware support has been dropped or changed in this kernel + modules, which is why I'm having the problems. Cheers Steve

I took all options and disabled this, that and the other on the boot-command-line, and with vga=0x0318 acpi=0ff noapic nolapic noapm it booted the new kernel OK. All I need to do now, is work out which of these options is actually making it work, and once I've done that, if there's any work arounds to remove the need for the command-line flag. Steve

With all those options, it booted OK, but some things like temperature sensor applets didn't work. For a while, I continuted to boot with the Kernel version that came with Lubuntu 12.04 (Ubuntu 12.10, kernel 3.0.0-26-generic I think) I installed a bunch of updates yesterday, and I checked, and the newest kernel Ubuntu 12.10, kernel 3.5.0-22-generic boots fine without problems, and without command line switches.

I can't remember what the problem was now, but Mint was misbehaving before Christmas, and an update cured that. -- Tony
