In-reply-to: Your message of "Sat, 25 Jul 1998 21:32:52 BST." <199807252032.VAA00175@awfulhak.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Date: Tue, 04 Aug 1998 08:04:28 +0100 From: Brian Somers Sender: owner-freebsd-ports@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I've found out more about this flickering problem.... it only occurs when the laptop is physically warm - the warmer, the more flickering. If the machine sleeps for ~15 minutes, it'll wake up with a perfect picture and that picture will start to deteriorate with the building heat. If I switch the display off for 15 minutes it makes no difference. This is all under load. If the machine is idle it lasts a lot longer (the fan is more effective I guess....) Has anyone else seen this problem ? I'm pretty much convinced that it's a hardware problem now, so I'll probably return the machine (second time) nearer the end of the week.
