Dobrý den,
během práce s F21 (KDE) se mi začalo stávat, že se ztratí hlavní dolní panel a nejde kliknout na plochu, pouze lze klávesnicí přepínat mezi běžícími okny a v nich pracovat. Můžete mi prosím poradit, jaký log mám sledovat, kde bych se dozvěděl, co se stalo, případně jaké další údaje potřebují zdejší odborníci pro odhalení problému?
Děkuji.
Zkus ~/.xsession-errors ale je to takovy pelmel. Taky bych se podival do /var/log/messages jestli tam neni nejaky “segmentation fault” coz bude nejpravdepodobnejsi dost mozna to souvisi s grafickou kartou.
Jako “workaround” muzes zkusit
Alt+F2
killall plasma-desktop && plasma-desktop
Zdravím.
Tak jednak jsem zjistil, kdy se to stane. Používám Chrome a když přepnu nějakou flash aplikaci do plné obrazovky, tak po návratu je pád. V messages jsem našel toto:
