<div dir="ltr">Hmmm, and then even weirder. After my screen was locked with XScreensaver. Monitor using usb->hdmi has frozen with a part of what was the screensaver at the time. Nothing new in Xorg.0.log. In dmesg I get this. Then monitor is frozen with that until I turn it off with xrandr and then back on again.<br><br>dmesg<br>[12829.941499] NVRM: GPU at PCI:0000:01:00: GPU-2b1c658b-6a27-a224-308e-0390d9ce6746<br>[12829.941506] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12830.037145] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12830.896808] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12832.239084] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12833.679389] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12834.444186] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12837.606244] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12838.851853] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12841.142955] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12841.718110] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12842.301406] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12843.261192] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12843.826331] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12847.282295] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12847.852584] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12849.000491] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12850.245880] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12854.756696] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12857.820104] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12861.076843] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12862.617239] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12862.713768] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12863.191928] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12863.571298] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12867.842494] NVRM: Xid (PCI:0000:01:00): 12, COCOD 00000001 00000000 00000030 00000100 01eba420<br>[12871.524667] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12871.622157] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12873.248926] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12877.843699] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12879.189930] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12880.817791] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[12883.500081] NVRM: Xid (PCI:0000:01:00): 6, PE0001 <br>[16146.454233] [drm] write mode info 153<br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Oct 7, 2014 at 10:04 AM, daidoji70 <span dir="ltr"><<a href="mailto:daidoji70@gmail.com" target="_blank">daidoji70@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div>Hmm, thats weird.

I switch the mode to one I know the monitor can support and I'm back to the grey screen background.

(Almost there, just can't get my mouse onto the third monitor) Anyone have any ideas what was causing all these udl issues above and more importantly, how can I use my mouse on that third monitor?
