Kernel 4.0 RC (Release Candidate) series

[VinDSL]

I almost always run the mainline kernel for this leading edge stuff.

Me, too. I always run mainline kernels on all Linux distros - love them! Sometimes I compile, some times I don't.

Also, I seldom do fresh installs...

vindsl@Zuul:~$ echo && echo -n "Last Fresh Install: " && echo | ls -ld /var/log/installer | awk '{ print $6 " " $7 " " $8 }' && echo

Last Fresh Install: Jan 25 2014

... but, that's just me.

I was proposing one thread for the whole 4.0RC series this time, just to see if we like it or not [...]

While we're all on the same page, so to speak -- and, I'm thinking about it.

Here's the link I use to check the mainline kernel directory for updates...

I finally worked out what I was doing wrong and Ventrical put me on the path.

I was downloading linux-headers-blah-blah_amd64.deb and linux-image-blah-blah_amd64.deb but not linux-headers-blah-blah_all.deb.

EDIT: This is how I am getting on. Kernel 4.0 and Nouveau work well together but Nouveau has GPU lockup when selecting more than 10 lines of text in a Writer document. And not just on kernel 4.0. So, I move on to Nvidia which does not give GPU lockup but kernel 4.0 does not like Nvidia 340.76. It gives a very large/low screen resolution.

Oh, well. Such is life.

EDIT 2: I have been thinking. It is as if the Nvidia driver is not loading on kernel 4.0. Well, I did install it on kernel 3.18.13. I am now considering installing a later version Nvidia driver. Living dangerously. It must be spring. Either that or the tablets are having no effect.

Just played a dvd and it left my core cool.

nvidia-current will not build against this rc 4.n.n-n kernel. Not Supported; error.

edit: oh .. graham already said that

[grahammechanical]

For me getting an Nvidia driver working has gone from interesting to boring. Nvidia 346.35 is in the repositories as this command will reveal

sudo apt-cache search "NVIDIA binary driver"

So it should install with

 sudo apt-get install nvidia-346

And it does seem to install but on kernel 4.0 and 3.18.13 (latest stable) Ubuntu loads to very low resolution llvmpipe. The bottom of the Make.log file has this

make[2]: Target '__build' not remade because of errors.
Makefile:1390: recipe for target '_module_/var/lib/dkms/nvidia-346/346.35/build' failed
make[1]: *** [_module_/var/lib/dkms/nvidia-346/346.35/build] Error 2
make[1]: Target 'modules' not remade because of errors.
make[1]: Leaving directory '/usr/src/linux-headers-4.0.0-040000rc1-generic'
NVIDIA: left KBUILD.
nvidia.ko failed to build!
nvidia-modules-common.mk:248: recipe for target 'module' failed
make: *** [module] Error 1

It becomes really strange because Details will say llvmpipe or Gallium but Additional Drivers will say a proprietary driver is in use. So, the OS is as confused as I am Things work fine on Nouveau and I would be happy with it if it did not have that GPU lockup when selecting text in Writer.

Yes, I am overdue to do a fresh install on my test computer. It is somewhat of a mess right now.

Very cool, I have replaced my bookmark with your version.

Yes, I am overdue to do a fresh install on my test computer. It is somewhat of a mess right now.

I had to bite_the_bullet last year.

After testing GS Staging for (like) a year, my rig got to the point where it was impossible to do incremental upgrades, without wiping half the packages off my drive.

I was usually able to pull_a_rabbit_out_of_my_hat when that happened, but it finally got so bad it was easier and less time-consuming to just give-up and do a fresh install.

To get Nvidia drivers working on this kernel, check this thread on devtalk.nvidia.com

It is for 346.xx drivers, but maybe it will work for 304.xx also.

4.0RC2 is out. (It will be awhile before I can try it.)
