Fakt bych se tehle funce rad zbavil, na stanicich s horsim signalem radsi pouzivam Kaffeine, ale tam me zlobi zase jinci veci.

Koukam porad zadna reakce, no zatim sem s uspechem vyzkousel jen dat ve sledovani systemu zastavit proces account-daemon, a ikdyz porad v seznamu procesu je, zapisovani prestane, jestli se to rucni zastavovani osvedci, pokusim se doresit jak to udelat automaticky bez zadavani hesla, ono takhle mi to jednou prestalo zapisovat i samo, takze treba se to da i nekde nastavit.

Dalsi zjisteni, zapisuje se do /var/log/lightdm/lightdm.log a plni to zapisy:

Dela to tak s vlc, audacious, rhythmbox ale zadny dalsi program co sem zkouse mi tohle nedela.

[Savalas]

Tak to vypinani account-daemon nedela dobre nautilusu.

[Savalas]

Zkusil sem dat  /var/log/lightdm/ do ram disku, ale porad se nekam zapisuje, diskled intenzivne blika a neni cim zjistit co se deje.

[Savalas]

Takze klasika nekolik hodin prace a zase sem se o neco pohnutl takze krome /var/log/lightdm/lightdm.log, se tak intenzive prepisuje dokola cca 400B soubor v /var/lib/AccountsService/users, nejpodobnejsi bug sem nasel tenhle https://bugs.launchpad.net/ubuntu/+source/xfdesktop4/+bug/1318307 .  Kdyz dam  /var/log/lightdm/  a /var/lib/AccountsService/users do ramdisku, nezapisuje se na HDD prakticky nic, takze je to jasne identifikovane, dalsi zajimave zjisteni, ve virtual boxu nainstalovem 14.04 tenhle problem tak dramaticky neni, ale cim to je, se mi zjistit nepodarilo, oboji zapisuje, ale ne tolik intenzive, program strace  sem zkousel, ale log ma pak, kdyz dam neco prehrat ve vlc skoro 1MB, pro srovnani ve vboxu 80KB.

Doplneno: Neveril sem tomu, ale vypada to ze vyreseno, smazal sem /usr/share/dbus-1/interfaces/com.canonical.indicator.sound.AccountsService.xml a odkazujici /usr/share/accountsservice/interfaces/com.canonical.indicator.sound.AccountsService.xml. V /var/lib/AccountsService/users/"uzivatel" se totiz porad menily polozky:

Kód: [Vybrat]

[com.canonical.indicator.sound.AccountsService]
PlayerName=''
Timestamp=0
Title=''
Artist=''
Album=''
ArtUrl=''
PlayerIcon=<('themed', <['application-default-icon', 'application-default', 'application']>)>
Running=true
State='Playing'
a tak me google prez com.canonical.indicator.sound.AccountsService nasmeroval k tem souborum. Vysereno doplnim pocase, jestli se to osvedci a nenastanou problemy.

[Savalas]

Bez /usr/share/dbus-1/interfaces/com.canonical.indicator.sound.AccountsService.xml a /usr/share/accountsservice/interfaces/com.canonical.indicator.sound.AccountsService.xml, ubuntu funguje v poradku, zbytecne zapisovani prestalo, tazke beru za vyresene a asi by to mohlo tem co maji SSD a zaroven pouzivaji vlc, audacious nebo rhythmbox pomoct usetrit zivotnost disku.
