I've installed Ubuntu 20.04.1 64bit today (three times as I was testing
various different options). All GTK2 apps (for example gmrun, grun,
anything compiled from lazarus with gtk2 target which is default) starts
for 25 seconds. I ran strace to see what it was and I don't know. The
25s delay is at line containing the "(Timeout)" text.

I've tried to find what fd 12 is and it seems to be this:
$ cat strace.log | grep -e Timeout -e open | grep -e 12 -e Timeout
openat(AT_FDCWD, "/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 12
openat(AT_FDCWD, "/lib/x86_64-linux-gnu/libproxy.so.1", O_RDONLY|O_CLOEXEC) = 12
openat(AT_FDCWD, "/usr/lib/x86_64-linux-gnu/gio/modules/libgiognomeproxy.so",
O_RDONLY|O_CLOEXEC) = 12
poll([{fd=12, events=POLLIN}], 1, 25000) = 0 (Timeout)
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=7, events=POLLIN}], 3,
0) = 0 (Timeout)
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=7, events=POLLIN}], 3,
0) = 0 (Timeout)
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=7, events=POLLIN}], 3,
0) = 0 (Timeout)
So maybe libgiognomeproxy.so? On other forum I got suggestion that maybe
hostname is not in /etc/hosts but it is there:
127.0.0.1 localhost
127.0.1.1 desktop
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
This is how I installed ubuntu:
1. iso 20.04.1 amd64 on usb stick, tried bot SSD and normal hard drive
2. install ubntu in english
3. English (US), English (US)
4. Normal installation, Download updates, Install third party sw
5. Erase disk and install Ubuntu, Advanced features: Use LVM, Encrypt
6. 2x same password
7. Choose Bratislava location
8. Your Name: desktop
Computer name: desktop
username: desktop
2x password
Log in automatically
9. Wait for install to finish, restart, install updates, restart
10. Alt+F2 gnome terminal, sudo apt-get install gmrun
11. gmrun - it takes 20s to appear
