Dit is een probleem waar ik al een tijdje last van heb. Telkens wanneer ik een video voor een minuut of 10 aan het kijken ben valt het screen op zwart. Dit is normaal gesproken in te stellen op Systeem --> voorkeuren --> energiebeheer. Echter zodra je xgl gebruikt staat dit standaard op 10 min. en dit is niet aan te passen.
Dit geld voor meerdere ati systemen, ik heb het gezien op een ati radeon mobile 1100 en een ati radeon mobile 1300 beiden in combinatie met xgl.
Ik heb heel wat af gezocht en heb het idee dat ik steeds in een kringetje zoek. Tot nog toe ben ik niemand met hetzelfde probleem tegen gekomen. Weet iemand hier iets over of waar ik verder zou kunnen?
EDIT: ik gebruik gutsy, echter het probleem deed zich ook al in feisty voor.
