Can i upgrade LMDE to Kernel 3.19?
i want to install LMDE on my Surface and the 3.19 kernal has the necessary hardware support for the power button, the keyboard, and a few other things.
I was wondering if I had to go with Ubuntu or if I could upgrade to 3.19 on Debian?
Thank you.

''Linux kernel 3.19 has been officially announced by none other than its father, Linus Torvalds, on February 8, 2015.''

I'll try it in a few minutes and let you know.
Wish me luck?

Re: Can i upgrade LMDE to Kernel 3.19?
Linux mint's latest kernel is 3.13.0-46-generic. I doubt LMDE is much further along.
Whatever version of linux you decide to install there's always the option of downloading and compiling 3.19.
Good luck
UPDATE:
I just viewed Fred Barclay's post. I stand corrected

Re: Can i upgrade LMDE to Kernel 3.19?
Try one: FAIL.
My first hint something was wrong was that the Linux Mint icon seemed larger than normal. It hung longer than normal, so I ctrl+alt+f4 and sure enough, it was having trouble booting.
I downloaded linux-image-3.19.0-trunk-686-pae (3.19-1~exp1) from the link in my first post and installed it with GDebi (which I had used earlier to install 3.16--successfully ).
Restarted and found that nice little error message just waiting for me.
I'll probably try a little bit more in the next few days, but my call would be to use a different kernel if at all possible. For one, LMDE ships with 3.11; 3.19 is probably a bit out of its league.
Second, the package wasn't even in Debian Unstable repos, but rather in Debian Experimental. Breakages are expected--and wanted. This is how Linux tests itself.

Re: Can i upgrade LMDE to Kernel 3.19?
Update 2:
I removed the 3.19 kernel using GDebi and decided to try the reinstallation after installing linux-headers-3.19.0-trunk-686-pae. Unfortunately, (at least) one of the header's dependencies, linux-kbuild-3.19, is not available at the moment. So it might be a few before I can try installing 3.19 again.

Re: Can i upgrade LMDE to Kernel 3.19?
If you are willing to not use the stock Debian kernel, then you should be able to use 3.19. In fact, I'm typing this right now on a 3.19 kernel, distributed by Liquorix
HOWEVER: I installed the Liquorix 3.19 kernel on LMDE Betsy and Debian Sid. I have not installed it on the old LMDE, but I suspect it will do fine.
If you want to install it, do the following:
and add the following lines:
Save the file.
Now verify that the lines were saved.
Prepare LMDE to install the kernel.
Now it is ready to install, however, you will need to decide what kernel architecture you want. You have 3 options: 32-bit without PAE, 32-bit with PAE, or 64-bit. If you are unsure which to choose, see here.
For 32-bit without PAE, run
For 32-bit with PAE
For 64-bit
Reboot after the process completes.
That's it! You will now be running the 3.19 kernel on LMDE. On Betsy, I'm getting Liquorix updates through the Update Manager, just like for other software, but they are level 5 and you will have to manually select them if you have not chosen to automatically install level 5 updates. Also, you will not be able to see them if you haven't chosen for level 4 and 5 updates to be visible. So in a nutshell, if you don't choose for level 4 and 5 updates to be visible in Update Manager, you will not see (and therefore not install) updates for Liquorix.
Keep in mind this is for Betsy. I'm not sure how it would look in the old LMDE.
Special thanks to richyrich for making me aware of the liquorix kernel.

Re: Can i upgrade LMDE to Kernel 3.19?
Stupid question: did you run apt update before attempting the install?
Re: Can i upgrade LMDE to Kernel 3.19?
I did run apt-get update i did it again and posted results below.
Oh i failed to answer your previous question. Im using the LMDE 3/2014. LMDE-2 has dependency problems installing Compiz Which makes my home theater system look awesome.

But now i cannot install my ATI catalyst drivers. I do not use the repo drivers, i download the drivers from ATI and install them. So when i try to install the ATi drivers i get an error stating missing dependencies.

Any ideas?

Looks like their drivers are not updated for the new kernel yet. The open source radeon drivers worked out-of-the-box for me.zaileion wrote:killer de bug wrote:Maybe you should compile this kernel:
