Ma alustasin siis sellega et uuesndasin ubuntu 16.10 peale seal on uus kernel kus pidi mitmeid teemakohaseid parandusi olema. Eks näeb kas see juba aitab.
Samsung U28E590D on ühendatud displayporti kaudu.
Vilkumine tähendaks midagi sellist, et arvuti äratab monitori iga ~10 sekundi tagant hetkeks üles.
Saan aru et mul on ainult enable_hangcheck lubatud. Proovisin lisada /etc/modprobe.d/i915.conf. Sisuga options i915 enable_dc=1
Aga peale restarti jääb väljund samaks.
