Same here. I have an xps 13 running ubuntu 14.10. When I upgraded from 12.04 (as installed by dell) into 14.04, I had to blacklist i2c_hid. After upgrading to 14.10, i needed to remove the blacklisting, as others reported. Here is the interesting thing: I needed to blacklist two different i2c modules (but see my first note below).
#### me@myxps:~$ grep i2c /etc/modprobe.d/blacklist.conf # blacklist i2c_hid # blacklist i2c_i801 #### A few notes: * when dealing kernel settings in laptops, I find that it's often the case that it's better to shut down and power cycle, instead of restarting. It seems like the BIOS doesn't quite get the hardware reset on a restart. * Joseph: when testing upstream, what's the expected/desired behavior? It seems like 14.10 is already working ok for most users. It seems to me that the blacklisting was a workaround in 14.04, not needed anymore. Or are you asking those who still have issues after de-blacklisting i2c_hic ? To those folks, I suggest trying a full shutdown and remove the power chord, and perhaps also removing the blacklist for i2c_i801 and see if that helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1386077 Title: [Dell XPS 13 9333] Touchpad not detected on Ubuntu 14.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1386077/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
