The only installation method possible on this computer is from a USB key. Create one following this page.
In the following the MBR booting mode is assumed (UEFI boot mode was not tested).
To turn on the Legacy BIOS boot mode (aka MBR) in the BIOS menu, press
F2 at startup. Set Secure Boot to off and set boot list order to legacy.
Also change function keys from the multimedia mode.
After the GRUB menu a first couple of lines are garbage. To remedy, see Kernel mode setting#Early KMS start.
Built-in microphone does not work out of the box. To enable,
create a file
/etc/modeprobe.d/modeprobe.conf with a line
options snd-hda-intel model=laptop
and unmute microphones in alsamixer (press
M on devices with an
Backlight (and XFCE)
For those with sensitive eyes the default handling of backlight in XFCE can be troublesome.
The range of the intel_backlight on this laptop is 7812 steps, however hardcoded 10 steps what might be too coarse.
acpi_backlight=vendor to the kernel parameters creates
max_brightness=15, and power-manager now steps with 20% of it (3 points), which may also be suboptimal.
The usual workaround to assign commands
xbacklight +5 and
xbacklight -5 to the function keys
Fn+F5/F4 (using Settings->Keyboard) to finer-grained control does not solve the problem, because the power manager intercepts keystrokes.
Disabling the brightness keys in the power manager AND enabling the above keyboard shortcuts somehow works (decreasing brightness and increasing it again does not always give you the same number). Test it to see if you are fine with such a behavior.
Finest grained control of the backlight can be achieved with the direct setting
# echo XXX > /sys/class/backlight/intel_backlight/brightness
To complicate things even more, this value is not saved after reboot if it is less than 390, because systemd is hardcoded to have at least 5% of max_brightness at start-up. If your favorite brightness is below 390, the only way is to run this number on every boot.
