Installing unofficial kernels

In addition to the officially supported kernel versions, other kernels are available for ROSA R9 and newer. They may be helpful when support for a newer (or, sometimes, older) hardware is needed but is missing in the current kernel. They can also be used for debugging, experimentation, etc.

Several stable kernel versions are available here: for 64-bit systems, for 32-bit systems.

Note 1. Network connection is needed to install these kernels. Please, do not turn off the power during the installation process.

Note 2. Proprietary drivers (e.g., nvidiaXYZ) may or may not work well with the unofficial kernels.

One can execute the following commands to install kernel 4.12.x, for example.

for x86_64:

  sudo urpmi.addmedia kernel_4.12 http://abf-downloads.rosalinux.ru/kernels_stable_personal/repository/rosa2016.1/x86_64/kernel_4_12/release/
  sudo urpmi kernel-nrj-desktop-4.12-latest kernel-nrj-desktop-4.12-devel-latest cpupower

for i586:

  sudo urpmi.addmedia kernel_4.12 http://abf-downloads.rosalinux.ru/kernels_stable_personal/repository/rosa2016.1/i586/kernel_4_12/release/
  sudo urpmi kernel-nrj-desktop-4.12-latest kernel-nrj-desktop-4.12-devel-latest cpupower

It is needed to reboot the system after that and then select the new kernel at boot time.

To use the previous kernel again, just select it in the GRUB (boot loader) menu at boot time.
