CHROME et écran TFT "spécial"
Bonjour à tous,
J'essaye d'installer la 10.04 sur une config spéciale avec un VIA C7M (CN700) donc avec OpenChrome.
Mon écran externe marche bien (VGA externe) et c'est un écran "normal".
Mon écran "embarqué" est un sharp (ou équivalent) d'une résolution de 800x480.
Le PB est que le serveur X quand il démarre foire complètement la config du petit écran et celui-ci part en vrille (extrait du log, je vous épargne la longue liste ensuite):
(II) CHROME(0): ViaDFPDetect
