I truly love Mint 18 Beta, but as I mentioned in my last post, I’ve been having random freezes, 2 or 3 a day when doing general computer work, and 100% of the time if I try to Normalize audio in Audacity. These freezing problems were also occurring in Mint 17.3 after I let a kernel update proceed.
After much experimenting while running Mint 17.3, I found the 3.16 kernel to be totally stable on my current platform.. Wanting to run Mint 18 Beta for its obvious software upgrades, I decided to attempt to downgrade the kernel.
Because the Update Manager does not offer a way to downgrade kernels using the GUI, I did it manually.
First was to find the kernel I wished to install. The kernel I wanted is in the Ubuntu Trusty kernel repository.
It is extremely important that you download the kernel image for your hardware architecture!
The kernel designed for my machine is the: linux-image-3.16.7-992-generic_3.16.7-992.201604152257_amd64.deb package
Once downloaded, you can simply double click on the package to open the package installer automatically, and once the installer reports that all dependencies are met, go ahead and install it.
Next, reboot your machine, and using the grub menu, select the kernel you wish to boot into. If you don’t see a grub menu at system startup, you can follow these instructions:
To show the grub menu at boot, you need to edit the GRUB config file, as I was booting quietly, not displaying the boot menu. To do that, simply drop to a terminal and edit it with your favorite text editor. I use medit
$ sudo medit /etc/default/grub
will open your text editor in super user mode.
You’ll see in the above example, I’ve commented out, using the # symbol, to have the boot process ignore the two commands at lines 7 and 8. Doing this, will now let me see the grub boot menu at startup. Save and close the file, and then, it’s very important that you tell grub that you’ve changed it. Do this by issuing the command:
$ sudo update-grub
Now it’s time to reboot. When you do, at the grub boot window, arrow down to Select previous Linux version, and select that.
Since downgrading my kernel, I have had zero, none, nada freezes on this machine. All the applications that are designed for Mint 18 work without issue, and I am one happy goat farmer!
When you’re done, go ahead and uninstall the kernels that were causing you problems.
As new versions of kernel version 4.2+ are released, I will of course give them a try as time allows.
