I recently upgraded from Ubuntu 12.10 to 13.04, and everything seemed to be extremely smooth and painless.<\/p>\n
However, a day or two later I suddenly noticed that the fan of my Ubuntu laptop (a Dell Latitude D630) was blowing like hell — the machine had stalled, I couldn’t wake up the desktop again, the screen remained black… I think the hang occurred after I had installed the first updates after upgrading to 13.04… Anyway, I had to hard-reboot the box… And this is when the trouble started… \ud83d\ude41<\/p>\n
Dunno what exactly happened, but the first thing I noticed was boot issues, something like “Cannot mount \/boot; ext2: no such filesystem” or something close to that. And indeed the kernel in Ubuntu 13.04 seems to lack support for that admittedly ancient filesystem (cat \/proc\/filesystems). I fixed that by creating a journal on my \/boot filesystem as follows (obviously if you have similar issues, you need to substitute your actual UUID in the command below), thereby migrating the filesystem to ext3:<\/p>\n
sudo tune2fs -j UUID=b8ad9dbd-a514-46c8-86af-d2a9cafe3d0c<\/pre>\nI also had to update \/etc\/fstab accordingly, of course:<\/p>\n
UUID=b8ad9dbd-a514-46c8-86af-d2a9cafe3d0c \/boot\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 ext3\u00a0\u00a0\u00a0 defaults\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 2<\/pre>\nNext thing I noticed that a couple of devices suddenly didn’t work: The touchpad, the touchpoint, my WiFi interface, etc. I quickly found out that obviously the modules required to support the devices weren’t loaded, and it was due to missing\/broken modules dependencies. The following file which keeps those dependencies<\/p>\n
\/lib\/modules\/3.8.0-19-generic\/modules.dep.bin<\/pre>\nwas truncated (size of 0 bytes).<\/p>\n
So I removed it and recreated it by<\/p>\n
sudo depmod -a<\/pre>\nAfter I rebooted everything seemed to be fine again.<\/p>\n
I hope that this concludes my negative experiences with 13.04, and that the laptop will runs as rock solid again as it used to be under 12.10.<\/p>\n","protected":false},"excerpt":{"rendered":"
