Support for Ubuntu 20.04

[rakeshtembhurne]

I haven't tried with Ubuntu 20.04 yet but I would like to know if the script is built to support newer versions automatically, or it needs to be changed per LTS and would need modifications.

Basically would like to install Ubuntu 20.04 LTS

The scripts themselves have no (or extremely limited and specific) knowledge of the specific distributions. One .specific exception to this is a check for the version of pulseaudio (introduced in Ubuntu 17.04, I THINK) that caused pulseaudio startup to fail because of soem interaction with a particular version of systemd. This is not really hard-coding the DISTRIBUTION, but doing some checks around the version of pulseaudio and/or systemd, which probably MAP to specific Ubuntu distributions. So you should be able to JUST TRY the remastering on Ubuntu 20.04 by setting source.iso to point at a live ISO of Ubuntu 20.04. That being said, by default, my remastering script by default either builds a new kernel or pulls in pre-compiled kernel from my PPA to make some of the hardware on the RDP Thinbook work. Ideally, my remastering script should do the following: - Check kernel version on the source.iso - Check kernel config on source.iso (/boot/config-$(uname -r) - If all required config elements are OK and kernel versionis >= required kernel version - do not compile kernel or replace kernel This is only an OPTIMIZATION of the remastering time / space. Beyond that, if you try Ubuntu 20.04 and you see some (new) problems, please report an issue. I have myself not (yet) tried remastering 20.04.

You can use it out of the box without remastering.

Using Ubuntu 20.04 on RDP 1130 fresh without remastering. All function key working fine. Audio still an issue #36 but not definitely #47 every thing seems working fine as in remastering. I think you can use Ubuntu 20.04 with out remastering it. Will check and give update if i find any other issue except #49 .

issue #36 solved in ubuntu 20.04 clean install with out remastering. llink given below
https://askubuntu.com/questions/768463/laptop-headphone-jack-produces-no-sound
https://askubuntu.com/questions/219342/no-sound-output-from-headphone-jack-ubuntu12-04?rq=1
Edit 1:
Also i have noticed that alsactl restore to be done in every reboot to get sound from headphone so i have done this

• Save alsa configuration to my local .config directory:
  alsactl store -f ~/.config/alsa.conf

• Add the following line to ~/.bashrc:

# reload alsa settings

if [[ -f ~/.config/alsa.conf ]]; then
alsactl restore ~/.config/alsa.conf
fi

Edit 2: find out updating bashrc file does not always produce the outcome i have tried another work around.
first when sound not coming from headphone i use:
sudo alsactl restore
then reboot the computer.
after getting sound from headphone i just save the alsa state by
sudo alsactl --file asound.state store to a local file and the replace the original file by cp asound.state /var/lib/alsa/asound.state
Now sound coming from headphone even after shut down.. Enjoy

issue #49 may be solved by unplug battery from laptop then reset by power on using only ac without battery. I haven't tried this as i am unable to find my screw-driver (lol). But will give update if it is solved...
