2604lts, avoid snaps as usual, consider Brave web browser instead?

2504, on Xorg slow startup of GTK{3,4} apps?

apt install xwaylandvideobridge
apt autopurge xdg-desktop-portal
# ( if you can, stop and avoid everything Gnome related )

gsettings set org.gnome.desktop.interface monospace-font-name 'Ubuntu Mono 11'


journalctl --vacuum-time=1d   # if out of disk space

# remove snaps? e.g.
lsblk # note all 
umount /snap/core20/1169 
umount /snap/lxd/21624 
umount /snap/snapd/13170 
... ...
snap remove core20 
snap remove lxd
... ...
snap remove snapd 
systemctl stop snapd
systemctl stop snapd.socket 
apt -y purge snapd

Ubuntu default for nVidia (if auto-uninstalled😆)

  $ sudo ubuntu-drivers autoinstall # if why?


beware legacy

Huge /var/log/journal ? once:

  # journalctl --vacuum-size=100M
  # journalctl --vacuum-time=3d

permanently:

# vi /etc/systemd/journald.conf
   .
   .
   SystemMaxUse=100M

# systemctl restart  systemd-journald

kvm/qemu on debian

reshape a data array? man rs
