PAE Kernel question

[joejohnston3]

Hi All,

Do I need to install the PAE Kernel under additional software with Linux Lite 1.0.8 or does it automatically use a PAE Kernel if it detects one during install? System Info seemed to show a newer Kernel then the one used through the PAE install so I am confused and need some clarification on what to use. Thank you.

Hi Joe. LL 106 uses a stock pae kernel. LL 108 uses a non-pae kernel at install and you can upgrade later by going to menu>system>install additional software.

Well, I wondered why there was a PAE Kernel installer. I was confused though as I went into System Info and it showed both processors and and SMP kernel and normally with non-PAE it was not showing both processors. I will now boot into the PAE Kernel and use that as it should probably help performance even though LL is already flying!

One last thing, it seems that this kernel is older with PAE. If that is so, is there a newer one we can use or should I stick with the one the installer chooses?

Hello!

Welcome to Linux Lite!

UIAM, I believe that the non-PAE kernel installed in Linux Lite is the last one that was produced, as all the newer kernels are PAE only...

Hmm. I've never tried what you're asking but here's the approach I'd take:
Update to pae with menu>system>install additional software
Reboot (at this point I'm assuming you've just installed a new kernel)
After reboot check for updates menu>install updates
Reboot if necessary (depending on any updates from above)

Before updating the kernel again use the system for some time. Is everything working? Upgrading the kernel further may not be necessary.

To determine what other kernel choices might be available:
Open synaptic menu>system>install/remove software
Reload
Mark all upgrades
Apply (**but don't install, yet**)
Read what Synaptic is suggesting. If packages were held back from menu>install updates they will probably be listed here. If nothing was held back then you'll need to select kernel packages by hand (and beyond the scope of what I can help with).
Determine what you want to do knowing that adding packages can cause system instability.
Cancel Synaptic install dialog if you don't want to install packages

Thank you for the input and I think I figured out that I am using the newest kernel as I tried to use sudo apt-get install linux-generic-pae linux-headers-generic-pae and it stated I had the newest already in use.

Everything is working very well and I have been using it for the last day with no issues. Linux Lite is so stable, fast and smooth that it is a pleasure to use. I am going to be using LL for my customers that are moving to Linux.

You're welcome. Happy to hear everything is working, stable, and fast.

I thought I had installed the PAE extensions to LL 1.0.8  but it was overlooked. Running System / Install Additional s/w / Install PAE Kernal it says:

Once you have installed and rebooted into the new kernel, you will need to install your drivers again to work with the PAE Kernel.

So which drivers are those likely to be? I've installed a video driver and CUPS printer driver. I can't recall any others. What about VBOX, CryptKeeper, DropBox, Skype and Wine?

Also, is it best to uninstall the drivers / above s/w if relevant before installing the PAE?

thanks
Alan
