HDMI er usynlig på PC1 men ikke PC2, hardwareproblem?

[Finn Bjerke]

Jeg har 2 laptops med nyeste Ubuntu, jeg forbinder med HDMI kabel til Lydpanel der så forbinder til tilhørende TV (LG), den gamle laptop finder HDMI den anden gør ikke

PC1: Acer Intel® Core™ i5-4210U CPU @ 1.70GHz × 4, kører 64 bit Ubuntu 14.04, finder ikke HDMI
PC2: Compaque Presario CS 238 Intel celeron b820 @ 1,70 X2 Kører 32 Bit Ubuntu 14.04 Finder HDMI

Jeg har 2 laptops med nyeste Ubuntu

Nej, 14.10 er den nyeste. Der er dog kun ca. 1 måned til 15.04 udkommer.

[Finn Bjerke]

OK OK men jeg formoder det hardware eller 32/64 bit som er forskellen her ? Eller måske jeg kan opgradere mig ud af problemet.... LTS er vel at foretrække generelt

[AJenbo]

32/64 bit gør ingen forskel. Nyre version af Ubuntu kommer med nyre og flere drivere der kan gøre at mere hardware fungere bedre, særlig nyre. Det der kan være at fortrække ved LTS er at man ikke skal opgradere så ofte, men så får man heller ikke de mange forbedringer der kommer med at opgradere. Så prøv om ikke det virker med seneste udgave, eventuelt også beta af 15.04

[Finn Bjerke]

Det er jo spændende om det løser problemet ....
