Hello everybody
at first I’m new to Linux world
I’m using debian buster 4 months ago with gnome desktop environment along side with windows 10 and everything was awesome.
after updates(as i remember) gnome startup became slower than before ( its takes about 10 seconds to show gnome login screen and another 5-7 seconds to show desktop after pressing login button).
after gnome startup i don’t have any problem and apps is running normally, the problem is only on startup.
trying to fix the problem:
1- i reinstalled the whole system many times and nothing changes.
2- i tried another operating systems with gnome like linux mint , manjaro linux and ubuntu and the same problem happens .
3- i disabled extensions and nothing changes.
does UEFI insecure boot has limitation that affect performance ?
does new gnome get more heavy than before ?
