I’ve managed to install the latest EOS (3.5) on Asus EEE 1215B but at first I couldn’t see the logon screen because it was too dark. This is a known problem on some Linux distros and specific hardware.
After some googling, I’ve managed a successful logon by temporarily editing GRUB kernel parameters at boot time. The following parameters do solve the problem: acpi_osi=Linux acpi_backlight=vendor
Problem is I can’t make these kernel parameters stick permanently. The traditional GRUB configuration method of editing variable “GRUB_CMDLINE_LINUX_DEFAULT” on file “/etc/default/grub” e using command “update-grub” does not work on EOS. I get a message stating that the command does not work on a OSTREE system.
How can I add these kernel parameters to GRUB configuration on EOS? Is there another way to configure the kernel? Is it possible to install EOS with permanent kernel configuration changes?
If I can’t find a workaround to this, I’ll have to give up EOS. I can’t even run the live ISO image from a usb stick without editing the GRUB kernel parameters at boot time.
Any help would be appreciated. Thanks in advance.
