[ubuntu] New PC Hardware Compatibility
dimanche 21 août 2016
I recently built my first pc but ever time I have tried to install Ubuntu it doesn't work. There are a lot of different types of errors that show up depending on what I do.
Erase and Install or Something Else:
When ever I try to do either of those methods it fails to mount or format a seemingly random partition. When I tried pressing continue on the error message it started the download but after failing to download scrollbar overlay it would only output a few other random errors but for the most part it would add time to the estimated download time. I let it try to download for a couple days but still nothing.
GParted then install:
When I try to use GParted it always failed to create or mount a partition in the same way as above. I never got to start the download when I did that.
Parted Magic from Ultimate Boot CD then install:
I used GParted on the Parted Magic distro from the UBCD live cd and the partitioning worked but when I went to install Ubuntu I clicked "Something else" and set up the partitions properly it gets to the download but does the same thing when I clicked continue in the formatting/mounting error.
Eventually I found a form post saying that my hard drive (a Western Digital) didn't like Ubuntu. So I bought a new one installed it but now I'm getting the same problems as before. I almost certain I've got the pc assembled right and the custom partions set up properly since my friend who helped me build it has built a lot of other computers (but always uses windows) and my brother is really good at Ubuntu and computer system stuff.

Authentication on Linux client with AD account through a domain trust relationship
dimanche 21 août 2016
Hello,
Here is the context:
2 different forests, connected through a two-way transitive trust relationship.Active Directory domains have 2012R2 domain controllers.
DOMAIN1.LOCAL is the main area where we find all objects (users, groups and computers).DOMAINE2.LOCAL is an area where we have only LINUX client computers.
What i need to know :
Is it possible to authenticate on a Linux client DOMAIN2.LOCAL with a Windows account which belongs to DOMAIN1.LOCAL?
Thanks for your help.
Regards,
Chris.

Move LVM based VMs from old KVM server to new KVM server
dimanche 21 août 2016
I want to move my LVM based VMs from my old KVM server to my new KVM server. What is "the way"?
I have:
KVM running on Ubuntu 12.04 - old system
with 5 VMs on LVM partition at /dev/sd3/vgroup/
all references to VMs in /dev/sd3/vgroup/ are actually symlinks to ../dm-1-5
KVM running on Ubuntu 16.04 - new system
with 1 vm, deb8, as a test
it also has the same structure /dev/sd4/vgroup/deb8
deb8 is a link to ../dm-0
a backup script that weekly stops each vm on old system and dd to a gzipped copy
If I unzip a copy of my backed-up vm on the new KVM box, and dd it to /dev/vgroup/testdata it copies the vm file and does not create the magic link to /dev/vgroup/testdata (which, I assume, should link to ../dm-1). The copied testdata VM in /dev/vgroup does not appear in my list of storage volumes in virt-manager.
I've read a lot of articles about using snapshots, dd, gzip, and dd back to the LVM directory. I also have the vm.xml config files backed up, but none of the articles I found seem to describe how this is to be used to bring up on a new server.
Can someone please explain all this magic (or definitive references) and maybe just a straight-ahead approach to moving LVM based VMs from one KVM server to another KVM server.
Thanks in advance,
Chris.

Ubuntu/Xubuntu works much slower than Windows 10
dimanche 21 août 2016
I've installed Windows 10 and Ubuntu 16.04 (also tried Xubuntu 16.04/14.04) on my brand new laptop i5 6200u/8gb/gt940m/240gb. I have problem with ubuntu performance, which doesn't occur on windows, where everything i've tried works just fine. On ubuntu I feel lagging when just typing - e. g. in codeblocks or in chromium.
In gtkperf i receive very different results - once it's like 2,5s and next time 20-30s (!).
I tried reinstalling ubuntu couple of times, with swap and without it. Also on empty ssd - with no effect at all. Memtest - no errors, ssd benchmarks - fine, cpu benchmarks - common results (benchmarking under windows).
I wonder if someone can tell me what causes my problems - thanks in advance!
