[Touch-packages] [Bug 1423796] Re: Unable to mount lvmcache root device at boot time
Correction, I was able to get gmoutso's solution to work. I realized that I needed to create a separate boot partition that didn't use lvm caching. In retrospect, this makes a lot of sense. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lvm2 in Ubuntu. https://bugs.launchpad.net/bugs/1423796 Title: Unable to mount lvmcache root device at boot time Status in initramfs-tools package in Ubuntu: Confirmed Status in linux package in Ubuntu: Confirmed Status in lvm2 package in Ubuntu: Confirmed Bug description: I'm experimenting with Vivid Vervet on a virtual machine and tried a new LVM feature, lvmcache. I made a cache for the root file system, rebuilt the initrd and rebooted the VM. At boot time, the system failed to activate the root LV. After some investigation, I found out, it's because the initrd is missing some essential stuff needed for activating a cached LV. The initrd was missing the dm-cache module. I regenerated the initrd with explicitly listing dm-cache in /etc/initramfs-tools/modules, but the system still can't boot up, because now it is missing the /usr/sbin/cache_check utility. As SSDs are becoming more and more common, I think it will be common to use them as cache for root file systems, thus it is mandatory to make sure that an initrd can mount an lvmcached root device when necessary, preferably without /etc/initramfs-tools/modules and other manual initrd hacking.

[Touch-packages] [Bug 1386721] Re: Graphics Slow After Upgrade 14.04 - 14.10
My Wine based games are so much choppy after upgrading from 14.04 to 14.10. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1386721 Title: Graphics Slow After Upgrade 14.04 - 14.10 Status in “xorg” package in Ubuntu: Confirmed Bug description: Using Gnome Ubuntu 14.10, Dell XPS 13, intel 915 Graphics After upgrading from 14.04 to 14.10 there are a lot of places where the graphics are working much slower than they were before: - Gnome Shell Interface is very sluggish, visible chops (redrawing) when pressing the [Super] key. - Selecting text in Gedit takes a full second pr. line Experiences some subjective improvement when I booted kernel 3.13.0-37 instead of 3.16.0-23, but that may be my imagination as the problem persists. I've searched google, forums, found a couple of relevant links that point to the issue being the Intel drivers. http://askubuntu.com/questions/53962...E2%86%92-14-10 http://www.webupd8.org/2014/10/ubunt...ent-1652086424 But the drivers currently in 14.10 should be newer than those supplied by Intel to 14.04 so that doesn't make sense to me. As one Intel developer wrote: I would like to point out that since what we do is bring more ecent versions of the software to the target distributions than they ship with, a 14.04 targeted installer is unlikely to bring much to a 14.10 installation, which most likely has the same or more recent versions already anyway.
