Dotaz: Ubuntu 20.04 (gmrun, grun) strasne pomale, cista instalacia

[gsnak]

Spravil som cistu instalaciu Ubuntu 20.04, niektore programy startuje strasne pomaly (25 sekund). Spustil som to cez strace a okolie toho kde to na 25 sekund zamrzne je tu, stoji to 25s tam kde je napisane (Timeout):

Netusite niekto cim by to mohlo byt? Ako to opravit? V top nic nezerie cpu, v dmesg neni nic. Je plne aktualizovane. Ten FD 12 je asi libgiognomeproxy.so?

$ cat zzz | grep -e Timeout -e open | grep -e 12 -e Timeout

Máš dostupnou síť, DHCPD ?

[gsnak]

Ano, internet normalne funguje.

[Peter Golis]

Tu ide ale o intranet, nie o internet. Hostname toho počítača má korektný záznam v /etc/hosts alebo v inom resolveri (DNS/DHCP)?

Podobná chyba sa totižto objavuje po premenovaná počítača.

[gsnak]

ok, takze ako to vyriesit? Mam do /etc/hosts pridat toto?

127.0.0.1 localhost
127.0.1.1 nazov

[Peter Golis]

Pre začiatok áno, ak sa ten počítač volá nazov.

Ale bolo by dobré vedieť, ako nastalo to, že to tam nie je. Teda či to je buģ inštalátora ktorý má dosah aj na iných užívateľov.

[gsnak]

Overim zajtra.

[gsnak]

Nie je to tym. V /etc/hosts je uz aj po instalacii toto:

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

[Peter Golis]

Škoda. Ak by toto bola východzia inštalácia, tak by stálo za to túto chybu reprodukovať a nahlásiť.

PS: Už som zažil aj non printable chars v hostname ktoré mali podobný efekt.

[gsnak]

Chybu som nahlasil: https://bugs.launchpad.net/ubuntu/+bug/1891245 V hodtname nie su neviditelne znaky.

[z_sk]

Spravne:

echo -e "127.0.0.1\tlocalhost\n127.0.0.1\t"`hostname`"\n" >> /etc/hosts

[gsnak]

Nepomohlo, nie je riesenim.

[ZAH]

Zkusil bych instalaci s vypnutým IPV6.

[pavele]

sudo apt install appmenu-gtk2-module

reboot

[gsnak]

nepomohlo

[gsnak]

Oprava, pomohlo, Uz to funguje. Preistotu som nainstaloval este aj libcanberra-gtk-module, neviem ktore z toho pomohlo.

sudo apt-get install appmenu-gtk2-module; sudo apt-get install libcanberra-gtk-module

Vdaka!

[gsnak]

Ok, funguje to ale len v unity, ked dam iny wm (napr. lwm) tak to zase caka 25s. Co musim spustit aby sa to aktivovalo?

[gsnak]

Uz som to nasiel. Porovnal som `ps aux` pri spustenom lwm a unity a skusanim som zistil ze je to toto: /usr/libexec/gsd-xsettings

[pavele]

Palec nahoru.
