Dell XPS 9350 (4.4.0 kernel)
The laptop has been running well on 4.4-rc7 but the new 4.4.0 kernel came out and I’d rather be on the newest officially released kernel (until Dell releases the official XPS 13 with an official kernel that is).
So I grabbed the newest kernel and installed it by running
cd /tmp wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-headers-4.4.0-040400_4.4.0-040400.201601101930_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-headers-4.4.0-040400-generic_4.4.0-040400.201601101930_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4-wily/linux-image-4.4.0-040400-generic_4.4.0-040400.201601101930_amd64.deb sudo dpkg -i linux-headers-4.4*.deb linux-image-4.4*.deb
Rebooted (remember to hit a key while grub is booting to select the kernel you want). Things are running like a champ so far. Will keep you posted and for anyone that installs please respond in the comments with your experiences.
Also, I wanted to clean up kernels I had installed (not the 4.2.x one that came with ubuntu though) and ran the following (help from this link)
(list kernels) [jim@xps~]$ dpkg -l | grep linux-image ri linux-image-4.2.0-16-generic 4.2.0-16.19 amd64 Linux kernel image for version 4.2.0 on 64 bit x86 SMP rc linux-image-4.3.0-wifitest-custom 4.3.0-wifitest-custom-10.00.Custom amd64 Linux kernel binary image for version 4.3.0-wifitest-custom ii linux-image-4.4.0-040400-generic 4.4.0-040400.201601101930 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP ii linux-image-4.4.0-040400rc7-generic 4.4.0-040400rc7.201512272230 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP ii linux-image-extra-4.2.0-16-generic 4.2.0-16.19 amd64 Linux kernel extra modules for version 4.2.0 on 64 bit x86 SMP ii linux-image-generic 126.96.36.199.18 amd64 Generic Linux kernel image (remove version i want) [jim@xps~]$ sudo dpkg --remove linux-image-4.3.0-wifitest-custom (rinse and repeat, i do not recommend deleting the 4.2.x kernel) (when you are finished uninstalling kernels run the following) [jim@xps~]$ sudo update-grub
