I posted this on the ubuntu forum but they said to post it here:
Today i did the long needed upgrade from 20.04 to 24.04 with a stop in 22.04. When i first got to 22.04 i discovered i could not run snap programs under different user id (will explain more later); and saw somewhere the 24.04 would fix this problem. With 24.04 i had the same problem AND a new problem - snap programs would not accept keyboard input.
I’ve been running snap chromium since 20.04 but to fix these two issues i reverted to debian for 3 key applications thunderbird, chromium and firefox.
In my setup i run two instances of firefox and chromium - i sandbox them via running them under different user id - however i’ve run into cgroup permission issues with 22.04 and 24.04 and after spending 2 hours an reading many different threads on the issue i did not find the magic to make it work. Even more fatal under 24.04 no snap program would accept keyboard input (ala chrome, firefox and thunderbird) which forced me to load these apps from debian pkgs. I did find under my searching several threads suggesting this is a problem with ibus but while that is great i did not find a fix to actually make them work.
I’m reporting this as it should all just work even if my setup is bit weird.
Some more details while i am running ubuntu 24.04 i use xfce4 gui/interface via install xfce4 packages (not xubuntu). I also use gdm3 and Xorg
