I've been playing around with Xinerama, using a 21" Sun GDM-5410 and an old 19" Dell P990 with a Matrox G450 dual-head graphics card. Good stuff. About 20 minutes after getting the idea that I should put two heads on soul, it was done. The primary display was the Sun monitor at 1920x1440x16, and the Dell monitor at 1600x1200x16. All was well. Then I found a killer deal on eBay for another Sun GDM-5410. $250 ship Then I found a killer deal on eBay for another Sun GDM-5410. $250 shipped from Chicago. The monitor was 2 years old and in perfect health. I had it shipped FedEx 2-day to minimize the possibility that UPS Ground troglodytes would mangle it during shipping.Alas.The monitor arrived on Wednesday, and the box looked fine. I pulled the monitor out and placed it on the desk, which is no small feat with a 75lb monitor. All cables were routed, soul was dropped to runlevel 3, the required changes were made to XF86Config-4, and I powered up the new monitor… and it blew the UPS. On closer inspection of the monitor, it seems that the box was dropped, upside down, during shipping. The visual ramifications were slight, only a crack in the rear panel and a 1/4″ separation of the front bezel and the screen. What actually happened was that the picture tube was forced down into the base of the monitor, causing enough damage to apparently short out the monitor, and my UPS.It then got interesting.Resigning myself to what is surely to be a month-long battle with FedEx over a damage claim, I replaced the broken Sun monitor with the Dell and brought soul back into runlevel 5… and the other GDM-5410 freaked out. It seems that some damage was done to the G450 when the broken Sun monitor was powered up, resulting in severe image degradation and scan fluctuations at 1920×1440. At 1600×1200 everything was fine, but I could no longer bring it up to the resolution I’ve been running it at for 2 years. On another system with a single-head nVidia graphics card, the monitor was fine. Three hours, three SVGA cables, another graphics card, three systems, and several hundred expletives later, all was back to normal…. I wound up reflashing the BIOS on the G450, then upgrading the XFree86 drivers on soul. Why did this work? I have no idea, but it did. Perhaps there was actually no permanent damage done to the G450, and my gyrations were all for naught… I have no idea. The monitor is at a repair shop, awaiting expert diagnosis, and I’m contacting the seller to see what can be done with FedEx. For all those interested, the damage photos are available. The worst part is that a beautiful monitor has been ruined by an uncaring shipping company. Is there no justice?
