I was unable to test another graphics card in the pcie slot, but the intel graphics from the cpu do not reproduce this issue.
I've also tested with another monitor with similar specs and the issue doesn't occur on that one, so I think it's isolated to only one monitor I have (the affected monitor is the NEC one in MonitorsUser.xml.txt). I do think that the PCI bus errors are probably related to the motherboard. Freezing and lockups are common with the SKU (XPS-8940 w/ discrete gpu). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065430 Title: Screen doesn't wake from keyboard action when keyboard is connected to monitor USB hub.
