You know if we had a Board for Debian Testing then the Stable users wouldn't have to get upset with these kinds of conversations.
Also they could just concentrate on questions for Stable Debian.
Am I off base here?
Sorry for hijacking the post.
Thanks

In the context of a frankendebian system I guess I can see how it would be very valuable. So if I was to pursue that kind of setup, I guess exploring btrfs snaphots would be a good idea.
You should right now move to btrfs filesytem, its the best thing ive ever done, its very easy to understand and it nevers fails. It allow you to do anything with the system, you restore the system snapshot with a tree comands.
Since then ive even installed opensuse, ubuntu and others system in the same partition.. , Ive upgraded to debian testing and rollback to stable snapshot, Ive tested several configurations with a snapshot for each one, keeping the stable ones. Its absurd to keep using ext4 when it doesnt give you snapshots, and they offer you identycal speed IO.

Hmmm..we're using a 4.13 kernel backported from Buster for the MX 17 betas right now...it supports more hardware for the amdgpu driver than the 4.13 currently in stretch-backports, and I boosted the kernel frequency from 250 to 1000 Hz for desktop use. Seems to work fine in the beta--I rebuilt the kernels in generic Stretch pbuilder VMs so they are good for Stretch, too.
Why is that?, Are newers kernel dropping old more suitable firmwares?, Im testing now 4.13 debian's.

stevepusser is referring to the frequency of the kernel interrupts — 250Hz is the default, 1000Hz gives less lag and a more "responsive" desktop (allegedly).

EDIT: check your Ubuntu kernel's interrupt frequency with:

Code: Select all

grep CONFIG_HZ /boot/config-${kernel-version}-$arch
Replace ${kernel-version} with the kernel version and replace $arch with the architecture (probably amd64).

I believe that one of the nicest things about free open source operating systems is that one can try out setups that have never been even considered before. In that sense I want to support idiosyncratic, bizarre new ways to use Debian. In this particular case it just seems that there are easier ways (backporting).

Responding to Spanish salad argument: I just mean that an important part of the btrfs stack is in the kernel and the devs always say to use the latest. It sure sounds like there could be some serious amount of risk there. The kind of risk that a snapshot wont fix (possible corruption of the subvolumes themselves). So, I would be cautious.

Yes, I just manually change a couple lines in the kernel configuration text file in /debian before the rebuild to effect that change, instead of running one of the configuration utilties that come with the kernel. The frequency can also be seen as how often the kernel does context switches--which is the switching of the CPU from one process or thread to another. Ubuntu's is also faster than the Debian kernel's 250 Hz, which is considered better for server use.

more likely about some borkage that persists even after restoring from btrfs snaphots... blaming debian or even kernel devs for it.

Now, Ive very very tested working very good and stable the following configuration, a easy and controlled mix of stable and testing, with ubuntu's kernel engine.
- Debian Stretch
- Ubuntu kenel 4.4.39_amd64
- Ubuntu kodi17.6 (Zesty)
- Opera Stable 42.0.2393.517

From Testing.:
- i965-va-driver, Libva-* (1.8.3)
- libdrm* (2.4.82)
- libav* (7:3.4-4)

This configuration works like a charm for an Acer Extensa5230.. 8)

i'm sort of out of sarcastic remarks concerning this user.
if it really "works like a charm", i guess we will never again see a help request from him/her anymore.

I refer the honourable member to this post where he breaks stuff yet again - http://forums.debian.net/viewtopic.php? ... 17#p660347

And who else would embark on research to find out if Ubuntu kernel would work in Debian?
I encourage this kind of courageousness (as Sir Humphrey Appleby would call it). It's almost as good as watching The IT Crowd.
