It’s been almost 4 years since my last linux OS upgrade. Last time it was Ubuntu 18.04, this time it is Ubuntu 22.04. Unfortunately, I do a lot of customization which can take plenty of post-installation time. This is one such list made primarily for self-reference later; it’d probably still be incomplete since I’m relying on memory.
sudo apt update sudo apt upgrade sudo reboot sudo apt install cpufrequtils xfce4 dolphin ark vlc sbcl kdeconnect timeshift texlive pdfgrep
Emacs packaged in the official ubuntu 22.04 repositories is version 27, while at the time of this writing, all the packages, .emacs and .emacs.d is tested for emacs 28.
sudo apt remove --autoremove emacs emacs-common sudo add-apt-repository ppa:kelleyk/emacs sudo apt install emacs28
I also do a fair bit of video processing from time to time. Having a capable GPU is handy; but putting it to use can be a bit of work. Fortunately, in this ubuntu version, I was able to get it to work in less than an hour or two.
Use a combination of the instructions at the following two pages:
- https://www.cyberciti.biz/faq/how-to-install-ffmpeg-with-nvidia-gpu-acceleration-on-linux/
- https://docs.nvidia.com/video-technologies/video-codec-sdk/12.0/ffmpeg-with-nvidia-gpu/index.html
Make sure to have hevc_nvenc for h265 encoding.
nvtop might be useful for checking GPU usage to see if the GPU is actually being used.
These include
- latest SBCL
- Mullvad VPN
- Zoom
- Google Chrome
- Syncthing
- Telegram
- For grub2 vs systemd-boot, see https://www.maketecheasier.com/grub-vs-systemd-boot/
- See the instructions at https://askubuntu.com/questions/1225791/how-to-replace-grub-with-bootloader-systemd-boot-in-ubuntu-20-04.
- It might be necessary to resize the EFI partition, for which these instructions might be useful.
Check with systemd-analyze blame to see the evil impact of snaps on boot time.
If convinced, follow the instructions at the following page or similar to disable snap: https://ubuntuhandbook.org/index.php/2022/04/remove-snap-block-ubuntu-2204/
Someone said that if boot speed is actually that much important, then one should consider hibernation instead of fooling oneself with fast startup.
Hibernation did work by default; I ended up using a swap partition.
- One needs to edit the
/etc/fstabto point to the swap partition. - And specify a
resume=UUID=[swap-partition-uuid]option to theGRUB_CMDLINE_LINUX_DEFAULTin/etc/default/grub, or equivalently in/boot/efi/loader/entries/[interesting-entry.conf]for systemd-boot.
Ubuntu 22.04 (too) showed a tendency to have random freezes. Though, fortunately, the issue seems distinct from those involving graphic drivers. In my case, I’m using XPS 9570, and the freezes happened during boot, before login, soon after login, as well as a few minutes after login, but also after suspend.
Perhaps there are two aspects here -
The solution as suggested here and that also worked for me is the following
sudo apt remove xfce4-screensaver sudo apt install light-locker # This additional fix seems required because I started with a Ubuntu 22.04 # base system instead of Xubuntu 22.04; so, both might be competing with # each other in some respects sudo apt remove xfce4-power-manager
Ubuntu 22.04 shipped with kernel 6.2 and 5.19. Unfortunately, the problem occured with both of them. The exact problem is still a mystery, but at the time of this writing, a suggestion to install kernel 6.0 seems to have yielded success and stop the freezing behaviors.
See instructions on a page such as this one.
