No boot on lts kernel

toniohelpdesk

I just installed the Kde version of Solus 4.1 and to have better compatibility with my RTL8822EU wireless card I installed the LTS kernel. I followed the installation as indicated, but on restarting the system, if I select the LTS kernel, it does not boot and only a flashing cursor blink on the screen. From a little check done the EFI partition is not mounted on startup and is not present in the Fstab file. How can I solve it? Thank you.

In another thread you said your CPU is a i7-8565u which launched Q3'18

Solus currently has the 4.9 series LTS kernel which launched 11th December 2016. My understanding is that LTS kernels only get fixes back ported to them not new hardware support or features. So if I am correct, it makes sense 4.9.210 will not work with your system.

LTS is there mainly for supporting older hardware.

On Arch I had no problems using the LTS version. I will try to solve the wifi and bluetooth problems caused by the rtw_pci module for the Realtek RTL8822BE differently. I'll try to check if there is the possibility to compile from github the drivers I used on Arch. Thank you very much!

toniohelpdesk There are multiple LTS kernels. 4.9 is likely older than the one you were using on Arch. We have intentionally stayed on 4.9 for compatibility when 4.14, 4.19, and 5.4 all are also LTS releases.

DataDrake I had a bizarre experience with Q40S based on Debian 9 at the time I tried it. The kernel was the oldest Linux LTS kernel and all the programs were very out of date too.

I have a pc with 2013 hardware and anything Ubuntu and more recent works better with my hardware. I no longer believe the older is more stable story, as far as Linux kernels and software goes.

I'm new to Solus and I hadn't noticed that the LTS version of the Kernel was from the 4.9 branch. :-)) I have compiled and installed alternative drivers for the RTL8822BE I hope they will work better. Thank You.

How can I switch to 4.19?

Solus does not provide a 4.19 series kernel. It has two supported kernel series the default linux-current (5.4.x which will be 5.5.x after this weeks sync) and linux-lts (4.9.x).

Any Linux distribution that does currently support 4.19.x will cease doing so come December 2020.

So you would have to do it yourself which means:

You are completely unsupported Solus will not help you
Any issues you have may be specific to your setup so even searching for issues might not do you any good
Learning to package for Solus
Configure the kernel
Compile and install it
Rebuild any of the following packages you need against that kernel version

bbswitch
broadcom-sta
nvidia-340-glx-driver
nvidia-390-glx-driver
nvidia-glx-driver
nvidia-beta-driver
nvidia-developer-driver
open-vm-tools
razer-drivers
v4l2loopback
virtualbox
vhba-module

Stay up to date with kernel releases
Find and apply your own patches to the kernel to work around issues
Do all of this every week sometimes multiple times a week.

Basically what I'm saying is... you don't.

Harvey well my wifi drivers dosen't work on 4.9 and ethernet driver works but not properly. 4.9 is too old I think and 5.4 has random freezes issues.

DataDrake

lekkerlinux That's more an anecdotal exception to the rule than a dismissal of it.

Stability isn't the reason we provide an LTS kernel. We do so for better compatibility with older systems. The later 4 series kernels broke many small things on older systems that look awhile to be fixed. The 5 series kernels have been just as bad or worse.

DataDrake That's great news for me and my old hardware. One important point was that everything worked great during the installation and the first update. When I tried to install Debian 10 last week using the netinstaller, the installation failed when it could not contact some mirror site to get the desktop option or something.

Anyway Solus is far less trouble and wherever it's phones home the updates work well. I am in South Africa.

Thanks for a no worries Linux distro that's snappier than Ubuntu and more user friendly than anything based on Arch(enemy).
