It's, uhm, interesting, isn't it? For clarity sake, this is a bit of an odd system. It's a Shuttle motherboard. From "dmidecode": Handle 0x0002, DMI type 2, 8 bytes Base Board Information Manufacturer: Shuttle Inc Product Name: FN78S Version: V10 Serial Number: > Rick a few interesting notes > In the last attachment Xorg.log claims that it's starts at ~81.456, whereas > dmesg states that X was running ~19.627541. > * Are those logs matching (ie. captured from the same boot/system startup) > I'm assuming that you've started your screensaver ~55.041877.

I booted the machine and as soon as the display locked up, I ssh'd to it from another machine and simply did a "dmesg >/rick/dmesg.txt" to capture as much as I could. The Xorg.0.log was already generated by the time I logged in via ssh. I combined the various logs into one file and shot it off to bugzilla. As far as the screen saver, I'm running XFCE and the lockup occurred as soon as I went through the "Applications Menu->Settings->Screensaver" menu tree. It tried to render the Screensaver window, got as far as drawing the box around it and everything locked up. After about a minute, the graphical screen blanked and I started getting the GPU lockup and going back to fbcon messages appeared on the console. The GUI screen then reappeared but it was still locked up. Again it cleared, the GPU lockup message appeared again and around and around we go. It might do the same thing rendering other windows, but I'm trying to be consistent to help debug this. I'll be more than happy to keep tinkering, but I've had like 3 hours of sleep in the last two days and I'm a bit knackered. I can pick this back up Monday. I'm in California if that's of any help. > Note: the following messages are harmless > nouveau E[ PBUS][0000:02:00.0] MMIO read of * FAULT at 0x1002** Glad to hear that! That's the first thing that appears after the plymouth "fill the bubble" screen and before I get the GDM login. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital <a href="mailto:ricks@alldigital.com">ricks@alldigital.com</a> - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - Squawk!
