By default, EFI installs will not show the boot menu and boot directly into Solus. By hitting space bar (repeatedly) during boot, the boot menu will appear (it may take a couple of goes to get the timing right). ## Appending kernel parameters to Solus boot Kernel parameters can be appended to boot via creating a file for `clr-boot-manager` to use when updating kernels. For example, to add `nomodeset` to boot options, you would create the file `/etc/kernel/cmdline` (as sudo): ``` echo 'nomodeset' | sudo tee /etc/kernel/cmdline ``` The settings should be on one line with a space between them. You will need to run `sudo clr-boot-manager update` for the options to be appended to boot. ## Displaying the Solus boot menu by default on boot The following command will set the timeout of the boot loader so that it appears by default. ``` sudo clr-boot-manager set-timeout 5 && sudo clr-boot-manager update ``` ## Installing an alternative kernel By default from `Solus 3`, the ISO ships with the `linux-current` kernel. The separate kernel branches can be added by installing the `linux-lts` or `linux-current` packages. Note that each kernel has separate module packages, so if you use these kernel modules, you'll need to install the one related to the kernel you are adding. |linux-lts |linux-current | |------------------------|--------------------------------| |bbswitch |bbswitch-current | |broadcom-sta |broadcom-sta-current | |linux-lts-headers |linux-current-headers | |nvidia-304-glx-driver |nvidia-304-glx-driver-current | |nvidia-340-glx-driver |nvidia-340-glx-driver-current | |nvidia-glx-driver |nvidia-glx-driver-current | |razer-drivers |razer-drivers-current | |v4l2loopback |v4l2loopback-current | |vhba-module |vhba-module-current | ### Change the default kernel branch to boot After successfully booting into a kernel from the `current` or `lts` branches running `sudo clr-boot-manager update` will make the booted kernel branch the default boot option going forward.
