I had to rollback to kernel 4.15 due to serious issues with 5.3

Post by nermeenhm »

Hi,

As you can see from the title, I had to roll back to kernel 4.15 as of today and it's working more than fine with me. Before that I was on the 5.0 but since its life will end this month I had to sacrifice and roll back now to 4.15. Needless to say that the 5.3 kernel was horrible and I couldn't even login with it; black screen at startup and total standstill (video card i195 issues).

My question: Will I be notified by the update manager when the kernel 5.5 is offered? I'm hoping my issue will be solved with the 5.5.

Thanks,

So, what is wrong with the 4.15?
If nothing, whats the problem?

Nothing at all so far, I'm just preparing myself in case anything goes wrong. It's the only single option I have and I was thinking that it would be wise to have at least one alternative kernel close by!

This sort fo thing happens, especially with old hardware. Paste the text output of inxi -Fxz run in the terminal.

I'm completely baffled by this post. Why do you want (or need) a newer kernel?

4.15 is the LTS kernel for Ubuntu 18.04 LTS. There are literally millions of computers running this kernel and Ubuntu is committed to supporting that kernel with security updates and bug fix updates until April of 2023. I can't understand why anyone would consider this a "sacrifice," or why anyone would want to upgrade install a newer, potentially buggy kernel if their computer is fully functional with the LTS kernel.

The more important question is, why would you install a newer, short term supported kernel at the end of it's life (5.0, which I'm guessing you installed in December or January, and which had it's last update about 3 weeks ago), and why would you expect a brand new, just into wide release kernel to be a smooth upgrade?

An even more important question is, why would you want to do this again in the future?

You say, "My question: Will I be notified by the update manager when the kernel 5.5 is offered? I'm hoping my issue will be solved with the 5.5." Please elaborate. What specific "issue" are you having that isn't solved by going to the LTS kernel and staying with that kernel?

If you have brand new hardware (designed and built since 2018 with brand new technology), and you either can't run kernel 4.15.0-* at all, or you have to turn off advanced features and cripple your new hardware to run kernel 4.15.0-*, then you're someone who needs a functional HWE kernel. That's currently the brand new and still working out the initial bugs 5.3.0-* kernel. That kernel will be supported at most until August of 2020.

More to the specifics of your question. The most likely next HWE kernel will be 5.4.0-*. That's the kernel that's in the current "daily" builds of Ubuntu 20.04 which is currently in testing. That will very likely be the next LTS kernel, and the "linux-*-HWE-18.04" meta-packages will likely lock onto that kernel permanently as the last upgrade after the 5.3.0 kernel passes out of support. Historically, when a new LTS version goes LTS (at the *.1 release), the previous LTS version HWE packages lock onto the new LTS kernel. Expect that to happen in late July or early August this year. It might happen sooner if the bugs in 5.3.0-* aren't fully resolved quickly. I'm fairly confident that there will never be an Ubuntu release of a 5.5 kernel for Ubuntu 18.04 LTS or for any distributions based on Ubuntu 18.04 LTS. If you need 5.5, you'll have to wait for the HWE packages on 20.04 (or 20.04 LTS), or for 20.10.

The OP is probably concerned about what to do once the 4.15 series goes end of life.

I had 5.3 whatever, installed in order to see 'how far I could go', but with the last update my poor old 'puter got rather 'jerky', so I've gone back to the LTS - I wonder if it's something to do with having an over 10 yr old 'puter!

... to see 'how far I could go',
This is a common misunderstanding. Newer kernels aren't better. Their function is to support hardware released since the last LTS kernel. You computer doesn't have that issue, obviously, so you're much better off using the LTS kernel, as it's more stable. Where things can get complicated is if you have a peripheral device which isn't supported by the LTS kernel, or a new graphics card, but you haven't mentioned any such thing.

Whilst I don't fundamentally disagree with the stick with what's known to work philosophy you both espouse, it's a bit of an over-simplification to state that newer kernels series are only for support of newer hardware. They can also bring new kernel features, refined support of existing hardware, performance improvements in extant drivers, schedulers, file system performance etc. All of course with the risk of new bugs, incompatibilities etc. So if stability isn't essential for a particular user, and the user is comfortable with how to switch back there's nothing fundamentally wrong with trying the newer kernel series even if the hardware doesn't technically need it.

As a personal example my 9th Gen Intel Dell laptop works fine on 4.15, 5.0 and 5.3, and is theoretically fully supported by kernel 4.15. But it's wireless connection stability is much better on kernel 5 and 5.3 than 4.15. I know what kernel I'll be using.

I agree with smurphos and I want to add, that’s why it is important to have always good backup.
You have to understand, that Linux distros in general are testing distros, because they have to introduce new software for the new hardware, so it is understandable to have issues with the old PC or laptop which uses kernel for new PC or laptops.
On the other hand a component like wireless driver which already mention by smurphos could have problems with the current kernel which will be solved with a newer kernel but could have issues with your Virtual Box for example.
So, a small operating system around 30-40 GB and a good backup, can very fast bring your OS in the previous good condition.

I can't understand why anyone would consider this a "sacrifice," or why anyone would want to upgrade install a newer, potentially buggy kernel if their computer is fully functional with the LTS kernel.
Ok, kernel 4.15 was not installed on my system. I have only just installed Mint's new version 19.3 (just a few weeks ago) and it worked with the 5.0 kernel. I didn't even have the 4.15 running to be able to know if it will work or not! So, now that's it's working I don't have any other kernel on my system except this one (I had to remove all 5.0 and 5.3 kernels) and I'm sure I must've read somewhere that it's better to have at least 2 kernels on your system in cause something goes wrong! Look I'm admitting that I'm totally and absolutely a newbie in Linux or Mint or any of this technical stuff and as you know people with ZERO knowledge are always taking unnecessary precautions to compensate for their lack of knowledge. That's why I've posted this question here in the newbies section. Thanks.

You can have and install 2 extra kernels and with this configuration you will boot from the last operation system you use. For example if you boot from kernel 4.15 will always boot the 4.15 kernel.
If you install newer kernels but you use older kernel then you should run after the installation of the newer kernel.

Code: Select all

sudo update-initramfs -uk all ; update-grub
To change the configuration how to boot.

Code: Select all

sudo xed /etc/default/grub
Add the missing commands and alter the existing ones.

Code: Select all

GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true
#GRUB_HIDDEN_TIMEOUT=0
#GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
Save close the file and after that.

Code: Select all

sudo update-grub

I'm sure I must've read somewhere that it's better to have at least 2 kernels on your system in cause something goes wrong!
The idea there is that, when there's an update, you keep your current kernel as a backup in case it turns out the newer one causes a problem which didn't manifest immediately. You can achieve pretty much the same thing in your case by installing the 4.15.0-76 kernel.

Now that sounds like a very sensible and easy solution to do :D :D :D why can't everything be so simple as that? Thanks a lot for your time. This is exactly what I'll be doing right away.
